And MCP makes the experience even better. With Flexisign MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Flexisign with - [OpenAI Agents SDK](https://composio.dev/toolkits/flexisign/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/flexisign/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/flexisign/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/flexisign/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/flexisign/framework/openclaw) - [Hermes](https://composio.dev/toolkits/flexisign/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/flexisign/framework/cli) - [Google ADK](https://composio.dev/toolkits/flexisign/framework/google-adk) - [LangChain](https://composio.dev/toolkits/flexisign/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/flexisign/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/flexisign/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/flexisign/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/flexisign/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 Flexisign to Codex ### How to install Flexisign 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 Flexisign MCP server, and what's possible with it? The Flexisign MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Flexisign account. It provides structured and secure access to your e-signature templates, so your agent can perform actions like listing document templates, surfacing available forms, and streamlining your e-signature workflow automatically. - Template discovery and listing: Quickly retrieve and display all available Flexisign templates directly through your agent. - Automated onboarding workflows: Let your agent surface the right template for onboarding, contracts, or agreements without manual searching. - Pre-signature document preparation: Enable your agent to fetch templates so you can prepare documents for signature faster. - Template-driven workflow automation: Use agent-powered discovery to launch automated processes based on the exact templates you need. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `FLEXISIGN_LIST_TEMPLATES` | List Templates | Tool to list all available document templates. Use when you need to retrieve and display templates from your FlexiSign account after connecting. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Flexisign MCP server provides comprehensive access to Flexisign operations through Composio. Once connected, you can perform all major Flexisign actions directly from Codex using natural language commands. ## Complete Code None listed. ## Conclusion ### Conclusion You've successfully integrated Flexisign with Codex using Composio's MCP server. Now you can interact with Flexisign directly from your terminal, VS Code, or the Codex App using natural language commands. Key benefits of this setup: - Seamless integration across CLI, VS Code, and standalone app - Natural language commands for Flexisign operations - Managed authentication through Composio - Access to 20,000+ tools across 1000+ apps for cross-app workflows - CodeAct workbench for complex tool chaining Next steps: - Try asking Codex to perform various Flexisign operations - Explore cross-app workflows by connecting more toolkits - Build automation scripts that leverage Codex's AI capabilities ## How to build Flexisign MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/flexisign/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/flexisign/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/flexisign/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/flexisign/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/flexisign/framework/openclaw) - [Hermes](https://composio.dev/toolkits/flexisign/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/flexisign/framework/cli) - [Google ADK](https://composio.dev/toolkits/flexisign/framework/google-adk) - [LangChain](https://composio.dev/toolkits/flexisign/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/flexisign/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/flexisign/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/flexisign/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/flexisign/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 Flexisign MCP server, the agents and LLMs can only access a fixed set of Flexisign tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Flexisign 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 Flexisign tools. ### Can I manage the permissions and scopes for Flexisign while using Tool Router? Yes, absolutely. You can configure which Flexisign 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 Flexisign data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
