And MCP makes the experience even better. With Convex MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Convex with - [OpenAI Agents SDK](https://composio.dev/toolkits/convex/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/convex/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/convex/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/convex/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/convex/framework/openclaw) - [Hermes](https://composio.dev/toolkits/convex/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/convex/framework/cli) - [Google ADK](https://composio.dev/toolkits/convex/framework/google-adk) - [LangChain](https://composio.dev/toolkits/convex/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/convex/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/convex/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/convex/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/convex/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 Convex to Codex ### How to install Convex 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 Convex MCP server, and what's possible with it? The Convex MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Convex account. It provides structured and secure access so your agent can perform Convex operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `CONVEX_CREATE_DEPLOY_KEY` | Create deploy key | Tool to create a deploy key for use with the Convex CLI.

With a standalone Convex MCP server, the agents and LLMs can only access a fixed set of Convex tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Convex 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 Convex tools. ### Can I manage the permissions and scopes for Convex while using Tool Router? Yes, absolutely. You can configure which Convex 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 Convex 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)
