And MCP makes the experience even better. With Exa MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Exa with - [OpenAI Agents SDK](https://composio.dev/toolkits/exa/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/exa/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/exa/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/exa/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/exa/framework/openclaw) - [Hermes](https://composio.dev/toolkits/exa/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/exa/framework/cli) - [Google ADK](https://composio.dev/toolkits/exa/framework/google-adk) - [LangChain](https://composio.dev/toolkits/exa/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/exa/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/exa/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/exa/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/exa/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 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Exa to Codex ### How to install Exa 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 Exa MCP server, and what's possible with it? The Exa MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Exa account. It provides structured and secure access to your Exa data platform, so your agent can perform actions like extracting answers from web data, running semantic searches, managing imports, and automating monitoring across your datasets. - Citation-backed question answering: Have your agent generate direct, source-cited answers or detailed summaries for your research questions using Exa’s advanced search. - Semantic similarity search: Quickly find web pages or documents that are semantically related to a given URL, complete with highlights or summaries for context. - Data import and webset management: Let your agent create, configure, or delete imports and websets to streamline data gathering and enrichment workflows. - Automated data monitoring: Schedule and manage monitors for websets to keep your data fresh and up-to-date with minimal manual intervention. - Event tracking and retrieval: Access a full history of system events or fetch details for specific events to stay on top of activity within your Exa environment. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `EXA_ANSWER` | Generate an answer | Generates a direct, citation-backed answer to a clear natural language question or topic using exa's search, adept at both specific answers and detailed summaries for open-ended queries. | | `EXA_CREATE_IMPORT` | Create Import | Tool to create a new import to upload data into a webset. use when you need to initialize an import before uploading the data file. | | `EXA_CREATE_MONITOR` | Create a Monitor | Tool to create a new monitor. use when you need to schedule automated updates for a webset without manual runs. | | `EXA_CREATE_WEBSET` | Create Webset | Tool to create a new webset with search, import, and enrichment setup. use when you need to configure and seed a webset in one call. | | `EXA_DELETE_IMPORT` | Delete import | Tool to delete an existing import. use when you need to permanently remove an import by its id. | | `EXA_DELETE_WEBSET` | Delete webset | Tool to delete a webset. use after confirming the webset id to permanently remove the webset and all its items. | | `EXA_FIND_SIMILAR` | Find similar | Finds web pages semantically similar to a given url using embeddings-based search, optionally retrieving full text, highlights, or summaries for results. | | `EXA_GET_CONTENTS_ACTION` | Get contents from URLs or document IDs | Retrieves configurable text and highlights from a list of exa document ids or publicly accessible urls. | | `EXA_GET_EVENT` | Get Event | Tool to get details of a specific event by its id. use when you have an event id and need its full details. | | `EXA_LIST_EVENTS` | List events | Tool to list all events that have occurred in the system. use when you need to paginate through the event history. | | `EXA_LIST_IMPORTS` | List imports | Tool to list all imports for the webset. use when you need to paginate through and monitor import jobs. | | `EXA_LIST_WEBHOOKS` | List webhooks | Tool to list all webhooks for websets. use when you need to view existing webhooks and paginate through results. | | `EXA_SEARCH` | Search | Performs a web search using the exa engine, useful for queries requiring advanced filtering, specific content categories, or ai-optimized prompting. | | `EXA_UPDATE_IMPORT` | Update import | Tool to update an import configuration by id. use when you need to modify an import's title or metadata. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Exa MCP server provides comprehensive access to Exa operations through Composio. Once connected, you can perform all major Exa actions directly from Codex using natural language commands. ## Complete Code None listed. ## Conclusion ### Conclusion You've successfully integrated Exa with Codex using Composio's MCP server. Now you can interact with Exa 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 Exa operations - Managed authentication through Composio - Access to 20,000+ tools across 870+ apps for cross-app workflows - CodeAct workbench for complex tool chaining Next steps: - Try asking Codex to perform various Exa operations - Explore cross-app workflows by connecting more toolkits - Build automation scripts that leverage Codex's AI capabilities ## How to build Exa MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/exa/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/exa/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/exa/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/exa/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/exa/framework/openclaw) - [Hermes](https://composio.dev/toolkits/exa/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/exa/framework/cli) - [Google ADK](https://composio.dev/toolkits/exa/framework/google-adk) - [LangChain](https://composio.dev/toolkits/exa/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/exa/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/exa/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/exa/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/exa/framework/crew-ai) ## Related Toolkits - [Firecrawl](https://composio.dev/toolkits/firecrawl) - Firecrawl automates large-scale web crawling and data extraction.

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