By the end, you'll have a working Ignisign agent that can start a new signature request for a contract, add a new signer to this application, delete a completed document by its id through natural language commands. This guide will help you understand how to give your LangChain agent real control over a Ignisign account through Composio's Ignisign MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Ignisign with - [OpenAI Agents SDK](https://composio.dev/toolkits/ignisign/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/ignisign/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/ignisign/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/ignisign/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/ignisign/framework/codex) - [OpenClaw](https://composio.dev/toolkits/ignisign/framework/openclaw) - [Hermes](https://composio.dev/toolkits/ignisign/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/ignisign/framework/cli) - [Google ADK](https://composio.dev/toolkits/ignisign/framework/google-adk) - [Vercel AI SDK](https://composio.dev/toolkits/ignisign/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/ignisign/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/ignisign/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/ignisign/framework/crew-ai) ## TL;DR Here's what you'll learn: - Get and set up your OpenAI and Composio API keys - Connect your Ignisign project to Composio - Create a Tool Router MCP session for Ignisign - Initialize an MCP client and retrieve Ignisign tools - Build a LangChain agent that can interact with Ignisign - Set up an interactive chat interface for testing ## What is LangChain? LangChain is a framework for developing applications powered by language models. It provides tools and abstractions for building agents that can reason, use tools, and maintain conversation context. Key features include: - Agent Framework: Build agents that can use tools and make decisions - MCP Integration: Connect to external services through Model Context Protocol adapters - Memory Management: Maintain conversation history across interactions - Multi-Provider Support: Works with OpenAI, Anthropic, and other LLM providers ## What is the Ignisign MCP server, and what's possible with it? The Ignisign MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Ignisign account. It provides structured and secure access to your electronic signature workflows, so your agent can perform actions like sending signature requests, managing documents, onboarding signers, and handling signature operations on your behalf. - Automated signature request management: Let your agent create, cancel, or delete signature requests, streamlining the entire e-signature process from start to finish. - Document initialization and deletion: Have the agent initialize new documents for signing or permanently delete documents when they're no longer needed. - Signer onboarding and removal: Effortlessly add new signers to your application environment or remove existing ones as your workflows change. - Webhook endpoint management: Allow your agent to create or delete webhook endpoints, enabling real-time notifications and integrations for signature events. - Application context retrieval: Fetch global application settings and environment configurations so your agent always works with up-to-date information. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `IGNISIGN_API_AUTHENTICATION` | Ignisign API Authentication | Tool to authenticate an application over Ignisign API and retrieve a JWT. Use when obtaining a bearer token before making other API calls. | | `IGNISIGN_CANCEL_SIGNATURE_REQUEST` | Cancel Signature Request | Cancel (close) a signature request to terminate it. This uses the Ignisign /close endpoint which permanently cancels the signature workflow. Use this when you need to abort a signature request that is in DRAFT or IN_PROGRESS status. This operation is idempotent - calling it on an already cancelled request returns success without error. | | `IGNISIGN_CREATE_DOCUMENT` | Initialize Document | Tool to initialize a document for a signature request. Use when linking a new document to an existing signature request after creating that request. | | `IGNISIGN_CREATE_SIGNER` | Create Signer | Tool to create a new signer. Use when onboarding a signer to an application environment after selecting a signer profile. | | `IGNISIGN_CREATE_WEBHOOK_ENDPOINT` | Create Webhook Endpoint | Tool to create a new webhook endpoint for an application. Use after obtaining application ID and environment to register for event notifications. | | `IGNISIGN_DELETE_DOCUMENT` | Delete Document | Tool to delete a specific document by its ID. Use when you need to permanently remove a document after processing is complete. | | `IGNISIGN_DELETE_SIGNATURE_REQUEST` | Delete Ignisign Signature Request | Permanently deletes a signature request from Ignisign by its ID. This action is irreversible and removes the signature request along with all associated data. The signature request ID can be obtained from the IGNISIGN_INIT_SIGNATURE_REQUEST action or IGNISIGN_GET_SIGNATURE_REQUESTS action. | | `IGNISIGN_DELETE_SIGNER` | Delete Signer | Tool to revoke/delete a signer from an Ignisign application environment. This action permanently revokes the signer's access and is idempotent (can be called multiple times on the same signer). Use when you need to remove a signer after confirming their signer ID. | | `IGNISIGN_DELETE_WEBHOOK_ENDPOINT` | Delete Webhook Endpoint | Delete a webhook endpoint by its ID. After deletion, returns the list of remaining webhook endpoints configured for the application environment. Use this tool when you need to remove a webhook that is no longer needed or to clean up unused webhooks. The webhook ID can be obtained from the create webhook or list webhooks endpoints. | | `IGNISIGN_GET_APPLICATION_CONTEXT` | Get application context | Tool to retrieve the global context of an application. Use when you need configuration and environment settings for a given app. | | `IGNISIGN_GET_DOCUMENT_INFORMATION` | Get Document Information | Tool to retrieve document metadata by ID. Use when you need detailed information of a specific document after obtaining its ID. | | `IGNISIGN_GET_MISSING_SIGNER_INPUTS` | Get Missing Signer Inputs | Tool to determine missing inputs needed for a signer in a specific signature profile. Use after selecting a signature profile and signer to identify required fields. | | `IGNISIGN_GET_SIGNATURE_REQUEST_DETAILS` | Get Signature Request Details | Tool to retrieve detailed information for a specific signature request. Use after creating or listing a signature request to inspect its details. | | `IGNISIGN_GET_SIGNATURE_REQUEST_DOCUMENT` | Get Signature Request Document | Tool to retrieve the document associated with a specific signature request. The action downloads the original file of a document. Provide `documentId` to select a specific document or omit to use the first available document of the request. | | `IGNISIGN_GET_SIGNATURE_REQUESTS` | Get Signature Requests | Retrieves a paginated list of signature requests for a specific Ignisign application and environment. Use this to list all signature requests (drafts, in-progress, completed, cancelled) in an application. Each signature request can have associated documents and signers. Returns pagination metadata to iterate through large result sets. Note: The app_env parameter must match your API key's environment scope. | | `IGNISIGN_GET_SIGNED_DOCUMENT` | Get Signed Document | Tool to download the signed document (signature proof) for a signature request. The action will: 1) Resolve the first documentId from the signature request details. 2) Try v4: GET /documents/{documentId}/signatures/PDF_WITH_SIGNATURES 3) Fallback v3: GET /v3/documents/{documentId}/signature-proof 4) Final fallback: GET /documents/{documentId}/file (original file) | | `IGNISIGN_GET_SIGNER_INPUT_CONSTRAINTS` | Get Signer Input Constraints | Tool to get signer input constraints. Use when you need to know which fields are required from signers for a given signer profile. | | `IGNISIGN_GET_SIGNER_INPUTS` | Get Signer Inputs | Retrieves the inputs provided by a specific signer for a signature request. Returns field values the signer has submitted (e.g., firstName, lastName, email). Use this after a signer has been added to a signature request to fetch their profile information. The signer must be associated with the specified signature request. | | `IGNISIGN_GET_SIGNER_PROFILE` | Get Signer Profile | Retrieve detailed information about a specific signer profile by its ID. Use this to get profile settings including integration mode, authentication methods, and associated signers. First use 'Get Signer Profiles' to list available profile IDs. | | `IGNISIGN_GET_SIGNER_PROFILES` | Get Signer Profiles | Retrieve all signer profiles for a specific Ignisign application environment. Use this tool to list all configured signer profiles that define how signers interact with signature requests. Each profile specifies integration mode (BY_SIDE, EMBEDDED, or MACHINE_TO_MACHINE), authentication methods, and other settings. Returns profile IDs which can be used when creating signers or signature requests. | | `IGNISIGN_GET_WEBHOOKS` | Get Webhooks | Retrieves all webhook endpoints configured for a specific Ignisign application environment. Returns the list of webhooks including their URLs, descriptions, and creation timestamps. Use this to audit existing webhook integrations or verify webhook configurations. | | `IGNISIGN_INIT_SIGNATURE_REQUEST` | Initialize Ignisign Signature Request | Initialize a new signature request in Ignisign. This is the first step in creating a signature workflow. After initialization, you can add documents (IGNISIGN_CREATE_DOCUMENT), assign signers (IGNISIGN_CREATE_SIGNER), and publish the request (IGNISIGN_PUBLISH_SIGNATURE_REQUEST) to start the signing process. | | `IGNISIGN_LIST_DOCUMENTS` | List Documents | Tool to retrieve documents linked to a signature request. The action works by calling the signature request context endpoint and extracting its documentIds, then fetching each document detail. | | `IGNISIGN_PROVIDE_DOCUMENT_CONTENT_DATA_JSON` | Provide Document Content Data JSON | Provides JSON content to an existing document in Ignisign. Use this action after creating a document with IGNISIGN_CREATE_DOCUMENT to attach structured JSON data that will be associated with a signature request. The JSON content is stored and can be used for document generation or data binding in signature workflows. | | `IGNISIGN_PROVIDE_DOCUMENT_CONTENT_FILE` | Provide Document Content File | Tool to provide file content for a document. Use after creating a document to attach its file content. | | `IGNISIGN_PROVIDE_DOCUMENT_CONTENT_PRIVATE_FILE` | Provide Document Content Private File | Provides private document content by submitting its SHA-256 hash to IgniSign. Use this after creating a document with IGNISIGN_CREATE_DOCUMENT when the document content should remain private (not uploaded). The hash proves document integrity without exposing its contents. The document status will change to 'PROVIDED' upon success. | | `IGNISIGN_PUBLISH_SIGNATURE_REQUEST` | Publish Signature Request | Tool to publish a draft signature request. Use after adding all documents and signer details to the draft. | | `IGNISIGN_SEARCH_SIGNERS` | Search Signers | Tool to search for signers within an application environment with pagination support. Use after obtaining application ID and environment. Requires a non-empty filter string to search by name, email, or external ID. Use '*' to match all signers. Supports page and pageSize parameters to paginate through large result sets. | | `IGNISIGN_UPDATE_DOCUMENT_INFORMATION` | Update Document Information | Tool to update document metadata. Use when you need to change a document's label, description, or external identifier after creation. | | `IGNISIGN_UPDATE_SIGNATURE_REQUEST` | Update Signature Request | Tool to partially update a signature request in DRAFT state. Use when you need to modify draft request metadata before sending. | | `IGNISIGN_UPDATE_SIGNER` | Update Signer | Updates an existing signer's profile assignment. Use this to change which signer profile a signer is associated with. The signer must already exist in the application environment. Requires: app_id (from Get Application Context), signer_id (from Create Signer or Search Signers), and signer_profile_id (from Get Signer Profiles). | | `IGNISIGN_UPDATE_WEBHOOK_ENDPOINT` | Update Webhook Endpoint | Tool to update an existing webhook endpoint. Use when you have a webhook ID and want to modify its destination URL or description. Example: Update the URL of webhook `68e7adc882353ea4e072bdbe` to `https://example.com/webhook`. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Ignisign MCP server is an implementation of the Model Context Protocol that connects your AI agent to Ignisign. It provides structured and secure access so your agent can perform Ignisign operations on your behalf through a secure, permission-based interface. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites No description provided. ### 1. Getting API Keys for OpenAI and Composio OpenAI API Key - Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider. - Keep the API key safe. Composio API Key - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Navigate to your API settings and generate a new API key. - Store this key securely as you'll need it for authentication. ### 2. Install dependencies No description provided. ```python pip install composio-langchain langchain-mcp-adapters langchain python-dotenv ``` ```typescript npm install @composio/langchain @langchain/core @langchain/openai @langchain/mcp-adapters dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates your requests to Composio's API - COMPOSIO_USER_ID identifies the user for session management - OPENAI_API_KEY enables access to OpenAI's language models ```bash COMPOSIO_API_KEY=your_composio_api_key_here COMPOSIO_USER_ID=your_composio_user_id_here OPENAI_API_KEY=your_openai_api_key_here ``` ### 4. Import dependencies No description provided. ```python from langchain_mcp_adapters.client import MultiServerMCPClient from langchain.agents import create_agent from dotenv import load_dotenv from composio import Composio import asyncio import os load_dotenv() ``` ```typescript import { Composio } from '@composio/core'; import { LangchainProvider } from '@composio/langchain'; import { MultiServerMCPClient } from "@langchain/mcp-adapters"; import { createAgent } from "langchain"; import * as readline from 'readline'; import 'dotenv/config'; dotenv.config(); ``` ### 5. Initialize Composio client What's happening: - We're loading the COMPOSIO_API_KEY from environment variables and validating it exists - Creating a Composio instance that will manage our connection to Ignisign tools - Validating that COMPOSIO_USER_ID is also set before proceeding ```python async def main(): composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY")) if not os.getenv("COMPOSIO_API_KEY"): raise ValueError("COMPOSIO_API_KEY is not set") if not os.getenv("COMPOSIO_USER_ID"): raise ValueError("COMPOSIO_USER_ID is not set") ``` ```typescript const composioApiKey = process.env.COMPOSIO_API_KEY; const userId = process.env.COMPOSIO_USER_ID; if (!composioApiKey) throw new Error('COMPOSIO_API_KEY is not set'); if (!userId) throw new Error('COMPOSIO_USER_ID is not set'); async function main() { const composio = new Composio({ apiKey: composioApiKey as string, provider: new LangchainProvider() }); ``` ### 6. Create a Tool Router session What's happening: - We're creating a Tool Router session that gives your agent access to Ignisign tools - The create method takes the user ID and specifies which toolkits should be available - The returned session.mcp.url is the MCP server URL that your agent will use - This approach allows the agent to dynamically load and use Ignisign tools as needed ```python # Create Tool Router session for Ignisign session = composio.create( user_id=os.getenv("COMPOSIO_USER_ID"), toolkits=['ignisign'] ) url = session.mcp.url ``` ```typescript const session = await composio.create( userId as string, { toolkits: ['ignisign'] } ); const url = session.mcp.url; ``` ### 7. Configure the agent with the MCP URL No description provided. ```python client = MultiServerMCPClient({ "ignisign-agent": { "transport": "streamable_http", "url": session.mcp.url, "headers": { "x-api-key": os.getenv("COMPOSIO_API_KEY") } } }) tools = await client.get_tools() agent = create_agent("gpt-5", tools) ``` ```typescript const client = new MultiServerMCPClient({ "ignisign-agent": { transport: "http", url: url, headers: { "x-api-key": process.env.COMPOSIO_API_KEY } } }); const tools = await client.getTools(); const agent = createAgent({ model: "gpt-5", tools }); ``` ### 8. Set up interactive chat interface No description provided. ```python conversation_history = [] print("Chat started! Type 'exit' or 'quit' to end the conversation.\n") print("Ask any Ignisign related question or task to the agent.\n") while True: user_input = input("You: ").strip() if user_input.lower() in ['exit', 'quit', 'bye']: print("\nGoodbye!") break if not user_input: continue conversation_history.append({"role": "user", "content": user_input}) print("\nAgent is thinking...\n") response = await agent.ainvoke({"messages": conversation_history}) conversation_history = response['messages'] final_response = response['messages'][-1].content print(f"Agent: {final_response}\n") ``` ```typescript let conversationHistory: any[] = []; console.log("Chat started! Type 'exit' or 'quit' to end the conversation.\n"); console.log("Ask any Ignisign related question or task to the agent.\n"); const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: 'You: ' }); rl.prompt(); rl.on('line', async (userInput: string) => { const trimmedInput = userInput.trim(); if (['exit', 'quit', 'bye'].includes(trimmedInput.toLowerCase())) { console.log("\nGoodbye!"); rl.close(); process.exit(0); } if (!trimmedInput) { rl.prompt(); return; } conversationHistory.push({ role: "user", content: trimmedInput }); console.log("\nAgent is thinking...\n"); const response = await agent.invoke({ messages: conversationHistory }); conversationHistory = response.messages; const finalResponse = response.messages[response.messages.length - 1]?.content; console.log(`Agent: ${finalResponse}\n`); rl.prompt(); }); rl.on('close', () => { console.log('\n👋 Session ended.'); process.exit(0); }); ``` ### 9. Run the application No description provided. ```python if __name__ == "__main__": asyncio.run(main()) ``` ```typescript main().catch((err) => { console.error('Fatal error:', err); process.exit(1); }); ``` ## Complete Code ```python from langchain_mcp_adapters.client import MultiServerMCPClient from langchain.agents import create_agent from dotenv import load_dotenv from composio import Composio import asyncio import os load_dotenv() async def main(): composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY")) if not os.getenv("COMPOSIO_API_KEY"): raise ValueError("COMPOSIO_API_KEY is not set") if not os.getenv("COMPOSIO_USER_ID"): raise ValueError("COMPOSIO_USER_ID is not set") session = composio.create( user_id=os.getenv("COMPOSIO_USER_ID"), toolkits=['ignisign'] ) url = session.mcp.url client = MultiServerMCPClient({ "ignisign-agent": { "transport": "streamable_http", "url": url, "headers": { "x-api-key": os.getenv("COMPOSIO_API_KEY") } } }) tools = await client.get_tools() agent = create_agent("gpt-5", tools) conversation_history = [] print("Chat started! Type 'exit' or 'quit' to end the conversation.\n") print("Ask any Ignisign related question or task to the agent.\n") while True: user_input = input("You: ").strip() if user_input.lower() in ['exit', 'quit', 'bye']: print("\nGoodbye!") break if not user_input: continue conversation_history.append({"role": "user", "content": user_input}) print("\nAgent is thinking...\n") response = await agent.ainvoke({"messages": conversation_history}) conversation_history = response['messages'] final_response = response['messages'][-1].content print(f"Agent: {final_response}\n") if __name__ == "__main__": asyncio.run(main()) ``` ```typescript import { Composio } from '@composio/core'; import { LangchainProvider } from '@composio/langchain'; import { MultiServerMCPClient } from "@langchain/mcp-adapters"; import { createAgent } from "langchain"; import * as readline from 'readline'; import 'dotenv/config'; const composioApiKey = process.env.COMPOSIO_API_KEY; const userId = process.env.COMPOSIO_USER_ID; if (!composioApiKey) throw new Error('COMPOSIO_API_KEY is not set'); if (!userId) throw new Error('COMPOSIO_USER_ID is not set'); async function main() { const composio = new Composio({ apiKey: composioApiKey as string, provider: new LangchainProvider() }); const session = await composio.create( userId as string, { toolkits: ['ignisign'] } ); const url = session.mcp.url; const client = new MultiServerMCPClient({ "ignisign-agent": { transport: "http", url: url, headers: { "x-api-key": process.env.COMPOSIO_API_KEY } } }); const tools = await client.getTools(); const agent = createAgent({ model: "gpt-5", tools }); let conversationHistory: any[] = []; console.log("Chat started! Type 'exit' or 'quit' to end the conversation.\n"); console.log("Ask any Ignisign related question or task to the agent.\n"); const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: 'You: ' }); rl.prompt(); rl.on('line', async (userInput: string) => { const trimmedInput = userInput.trim(); if (['exit', 'quit', 'bye'].includes(trimmedInput.toLowerCase())) { console.log("\nGoodbye!"); rl.close(); process.exit(0); } if (!trimmedInput) { rl.prompt(); return; } conversationHistory.push({ role: "user", content: trimmedInput }); console.log("\nAgent is thinking...\n"); const response = await agent.invoke({ messages: conversationHistory }); conversationHistory = response.messages; const finalResponse = response.messages[response.messages.length - 1]?.content; console.log(`Agent: ${finalResponse}\n`); rl.prompt(); }); rl.on('close', () => { console.log('\nSession ended.'); process.exit(0); }); } main().catch((err) => { console.error('Fatal error:', err); process.exit(1); }); ``` ## Conclusion You've successfully built a LangChain agent that can interact with Ignisign through Composio's Tool Router. Key features of this implementation: - Dynamic tool loading through Composio's Tool Router - Conversation history maintenance for context-aware responses - Async Python provides clean, efficient execution of agent workflows You can extend this further by adding error handling, implementing specific business logic, or integrating additional Composio toolkits to create multi-app workflows. ## How to build Ignisign MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/ignisign/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/ignisign/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/ignisign/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/ignisign/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/ignisign/framework/codex) - [OpenClaw](https://composio.dev/toolkits/ignisign/framework/openclaw) - [Hermes](https://composio.dev/toolkits/ignisign/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/ignisign/framework/cli) - [Google ADK](https://composio.dev/toolkits/ignisign/framework/google-adk) - [Vercel AI SDK](https://composio.dev/toolkits/ignisign/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/ignisign/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/ignisign/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/ignisign/framework/crew-ai) ## Related Toolkits - [Google Drive](https://composio.dev/toolkits/googledrive) - Google Drive is a cloud storage platform for uploading, sharing, and collaborating on files.

With a standalone Ignisign MCP server, the agents and LLMs can only access a fixed set of Ignisign tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Ignisign and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with LangChain? Yes, you can. LangChain fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Ignisign tools. ### Can I manage the permissions and scopes for Ignisign while using Tool Router? Yes, absolutely. You can configure which Ignisign scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Ignisign data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
