And MCP makes the experience even better. With Leexi MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Leexi with - [OpenAI Agents SDK](https://composio.dev/toolkits/leexi/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/leexi/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/leexi/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/leexi/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/leexi/framework/openclaw) - [Hermes](https://composio.dev/toolkits/leexi/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/leexi/framework/cli) - [Google ADK](https://composio.dev/toolkits/leexi/framework/google-adk) - [LangChain](https://composio.dev/toolkits/leexi/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/leexi/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/leexi/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/leexi/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/leexi/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 Leexi to Codex ### How to install Leexi 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 Leexi MCP server, and what's possible with it? The Leexi MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Leexi account. It provides structured and secure access so your agent can perform Leexi operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `LEEXI_CREATE_MEETING_EVENT` | Create Meeting Event | Tool to create a new meeting event in Leexi with timing, participants, and recording preferences. Use when scheduling a meeting that needs to be tracked and potentially recorded in the Leexi system. | | `LEEXI_DELETE_MEETING_EVENT` | Delete Meeting Event | Tool to delete a specific meeting event by UUID. Use when you need to permanently remove a meeting event record from the Leexi system. This is a destructive operation that cannot be undone. | | `LEEXI_GET_CALL` | Get Call | Tool to get details of a specific call or meeting by UUID from Leexi. Use when you need to retrieve call details including topics and transcripts. The simple_transcript provides paragraph-level timestamps, while the transcript includes word-level timestamps. | | `LEEXI_GET_MEETING_EVENT` | Get Meeting Event | Tool to retrieve a specific meeting event by UUID from Leexi. Use when you need to fetch details of a particular meeting event including timing, participants, and recording preferences. | | `LEEXI_LIST_CALLS` | List Calls | Tool to list all calls and meetings in your Leexi workspace with pagination support. Use when you need to retrieve call records. Note: AI-generated content like summaries and chapters may not be immediately available for newly created calls. | | `LEEXI_LIST_MEETING_EVENTS` | List Meeting Events | Tool to list all meeting events in your Leexi workspace with pagination support. Use when you need to retrieve meeting events from the workspace. | | `LEEXI_LIST_TEAMS` | List Teams | Tool to list all teams in your Leexi workspace with pagination support. Use when you need to retrieve team information or iterate through all teams in the organization. | | `LEEXI_LIST_USERS` | List Users | Tool to list all users in your Leexi workspace.

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