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 Acculynx MCP server, and what's possible with it? The Acculynx MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Acculynx account. It provides structured and secure access to your construction project data, so your agent can create jobs, manage contacts, schedule appointments, and organize calendars on your behalf. - Automated job creation and management: Instantly create new jobs in your Acculynx system, specifying contacts, addresses, categories, and more to streamline project setup. - Contact and lead management: Add new contacts or leads with detailed information, helping you keep your pipeline up to date and organized without manual data entry. - Appointment scheduling and tracking: Schedule initial job appointments or retrieve summaries of all job-related events, making it easy to keep teams and clients in sync. - Company representative assignment: Assign representatives to specific jobs to clarify project responsibilities and maintain accurate records of team involvement. - Calendar and contact type retrieval: Fetch lists of company calendars or contact types, supporting smarter scheduling, filtering, and contact management across your organization. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ACCULYNX_ADD_JOB_APPOINTMENT` | Add job appointment | This endpoint allows users to schedule the initial appointment for a specific job in the acculynx system. it is used to set up the first meeting or site visit for a construction or roofing project. the endpoint requires the job id, start date and time, and end date and time for the appointment. this is crucial for initiating the project workflow and ensuring that all parties involved are aware of the scheduled time for the first interaction. the appointment details are set in the context of the company's timezone unless otherwise specified. use this endpoint when a new job has been created and the first appointment needs to be scheduled with the client or at the job site. | | `ACCULYNX_CREATE_A_CONTACT` | Create a contact | Creates a new contact in the acculynx system with detailed information for use in roofing and construction project management. this endpoint allows for the addition of comprehensive contact details including personal information, company affiliation, communication preferences, and address information. it's particularly useful for adding new customers, leads, vendors, or any other type of contact relevant to construction projects. the endpoint provides flexibility in the amount of information that can be added, with only the contact type being required. use this when you need to add a new contact to your acculynx database or update your system with new lead information. note that while many fields are optional, providing as much information as possible will enhance the usefulness of the contact record for future project management and communication purposes. | | `ACCULYNX_CREATE_A_JOB` | Create a job | Creates a new job in the acculynx system with the provided details. this endpoint allows you to initialize a job with essential information such as the associated contact, location, job category, work type, priority, and trade types. it's particularly useful for setting up new projects or tasks within the acculynx platform for the roofing and construction industries. the endpoint requires at minimum a contact id and location address, with several optional fields to further customize the job entry. use this when you need to programmatically create new jobs in acculynx, such as when integrating with other systems or automating job creation processes. | | `ACCULYNX_CREATE_A_LEAD` | Create a lead | This endpoint creates a new lead in the acculynx system, specifically for residential roofing projects. it should be used when a new potential customer expresses interest in roofing services or when importing lead data from external sources. the endpoint captures essential contact information to initiate the lead management process. while it creates the lead, it does not assign priorities or sales representatives; these actions would need to be performed separately. the endpoint is designed for simplicity and quick lead entry, focusing on the most crucial identifying information. | | `ACCULYNX_JOB_APPOINTMENT_SUMMARY` | Job appointment summary | Retrieves a list of appointments from the calendar associated with a specific job in acculynx. this endpoint is used to fetch scheduled events, such as site visits, inspections, or project milestones, for a particular roofing or construction job. it provides valuable information for project management and scheduling purposes. the endpoint should be used when you need to view or manage the timeline of events for a specific job. it will not provide general calendar information or appointments unrelated to the specified job id. the response likely includes details such as appointment dates, times, descriptions, and associated team members, though the exact structure is not specified in the given schema. | | `ACCULYNX_LIST_OF_CALENDARS_FOR_THE_LOCATION` | List of calendars for the location | Retrieves a list of calendars associated with the authenticated user or organization in acculynx. this endpoint provides access to the calendar data, which is crucial for scheduling and organizing tasks in the roofing and construction project management context. it should be used when you need to obtain an overview of all available calendars or to gather calendar ids for use in other api operations. the endpoint returns basic information about each calendar, likely including identifiers, names, and possibly associated metadata. it does not modify any calendar data and is intended for read-only operations. keep in mind that the response may be paginated for large datasets, and additional parameters might be available for filtering or sorting the results, although they are not specified in the current schema. | | `ACCULYNX_LIST_OF_CONTACT_TYPES_RELATED_TO_THE_COMPANY` | List of contact types related to the company | Retrieves a list of all available contact types in the acculynx system. this endpoint is used to fetch the predefined categories or classifications for contacts, such as residential, repair, property management, and other job categories. it's essential for organizing and filtering contact information within the acculynx platform. the endpoint should be used when setting up new contacts, updating existing ones, or when needing to populate dropdown menus or filter options in the user interface. it does not create, modify, or delete contact types; it only provides the current list of available options. the response will likely include unique identifiers and names for each contact type, allowing for easy integration with other parts of the acculynx api or external systems. | | `ACCULYNX_UPDATE_COMPANY_REPRESENTATIVE` | Update company representative | This endpoint allows you to add a company representative to a specific job within the acculynx system. it is used when you need to associate a representative with a particular project or task. the endpoint requires the job's unique identifier and the representative's id to establish the connection. this operation is useful for assigning personnel to projects, tracking responsibilities, and maintaining accurate job records. it's important to note that this endpoint only adds the association and doesn't create new representative or job entries. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Acculynx MCP server is an implementation of the Model Context Protocol that connects your AI agent to Acculynx. It provides structured and secure access so your agent can perform Acculynx 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 Acculynx 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 Acculynx 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 Acculynx tools as needed ```python # Create Tool Router session for Acculynx session = composio.create( user_id=os.getenv("COMPOSIO_USER_ID"), toolkits=['acculynx'] ) url = session.mcp.url ``` ```typescript const session = await composio.create( userId as string, { toolkits: ['acculynx'] } ); const url = session.mcp.url; ``` ### 7. Configure the agent with the MCP URL No description provided. ```python client = MultiServerMCPClient({ "acculynx-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({ "acculynx-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 Acculynx 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 Acculynx 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=['acculynx'] ) url = session.mcp.url client = MultiServerMCPClient({ "acculynx-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 Acculynx 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: ['acculynx'] } ); const url = session.mcp.url; const client = new MultiServerMCPClient({ "acculynx-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 Acculynx 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 Acculynx 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 Acculynx MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/acculynx/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/acculynx/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/acculynx/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/acculynx/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/acculynx/framework/codex) - [OpenClaw](https://composio.dev/toolkits/acculynx/framework/openclaw) - [Hermes](https://composio.dev/toolkits/acculynx/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/acculynx/framework/cli) - [Google ADK](https://composio.dev/toolkits/acculynx/framework/google-adk) - [Vercel AI SDK](https://composio.dev/toolkits/acculynx/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/acculynx/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/acculynx/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/acculynx/framework/crew-ai) ## Related Toolkits - [Hubspot](https://composio.dev/toolkits/hubspot) - HubSpot is an all-in-one marketing, sales, and customer service platform.

With a standalone Acculynx MCP server, the agents and LLMs can only access a fixed set of Acculynx tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Acculynx 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 Acculynx tools. ### Can I manage the permissions and scopes for Acculynx while using Tool Router? Yes, absolutely. You can configure which Acculynx 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 Acculynx data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
