And MCP makes the experience even better. With Signwell MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Signwell with - [OpenAI Agents SDK](https://composio.dev/toolkits/signwell/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/signwell/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/signwell/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/signwell/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/signwell/framework/openclaw) - [Hermes](https://composio.dev/toolkits/signwell/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/signwell/framework/cli) - [Google ADK](https://composio.dev/toolkits/signwell/framework/google-adk) - [LangChain](https://composio.dev/toolkits/signwell/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/signwell/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/signwell/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/signwell/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/signwell/framework/crew-ai) ## TL;DR ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Signwell to Codex ### How to install Signwell MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## What is the Signwell MCP server, and what's possible with it? The Signwell MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Signwell account. It provides structured and secure access to your document signing workflow, so your agent can perform actions like sending signature requests, managing documents, handling webhooks, and retrieving account info on your behalf. - Automated document creation and sending: Have your agent generate new documents and instantly send them out for e-signature—no manual uploads or email juggling required. - Real-time document status retrieval: Let your agent fetch the latest status and details of any document, so you always know who has signed and what’s still pending. - Bulk send management: Effortlessly list and track large batches of signature requests, helping you stay organized when sending documents to multiple recipients. - Webhook automation and monitoring: Register or remove webhooks so your agent can monitor document events and respond instantly to completed, signed, or cancelled documents. - Credential and account validation: Quickly check and verify your Signwell account details and API credentials directly through your agent. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `SIGNWELL_CREATE_DOCUMENT` | Create Document | Tool to create and optionally send a new document for signing.

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