Exa MCP Server

Exa MCP Server HTTP MCP proxy to Exa's hosted MCP server at https://mcp.exa.ai/mcp. This Actor exposes a streamable HTTP endpoint so MCP clients can connect using an Apify-hosted URL with Bearer auth. ## How to use This server uses mcp-remote to connect to Exa and supports optional EXA_API_KEY (appended to the URL as exaApiKey). ## Connection URL MCP clients can connect to this server at: https://mcp-servers--exa-mcp-server.apify.actor/mcp ## Client Configuration Use this configuration in your MCP client (replace your-apify-token with your token from Apify Console): { "mcpServers": { "exa": { "type": "http", "url": "https://mcp-servers--exa-mcp-server.apify.actor/mcp", "headers": { "Authorization": "Bearer YOUR_APIFY_TOKEN" } } } } Optionally set EXA_API_KEY as an Actor environment variable to use your Exa key. ### Pay per event This Actor uses the Pay Per Event (PPE) model. Exa tool calls map to events defined in .actor/pay_per_event.json such as exa-get-code-context, exa-web-search, etc. Unknown tools fall back to tool-request. To charge users, define events in JSON format and save them on the Apify platform. Here is an example schema with the tool-request event: Event charging is performed in src/billing.ts based on the MCP method and tool name. To set up the PPE model: in Actor Monetization settings, choose Pay per event and paste the content of .actor/pay_per_event.json. ## Credits and links - What is Anthropic's Model Context Protocol? - How to use MCP with Apify Actors - All credits to the original authors of https://github.com/exa-labs/exa-mcp-server (or hosted Exa at https://mcp.exa.ai/mcp) - Claim this MCP server – write to ai@apify.com. - Apify MCP servers monorepo - Apify MCP server - Apify MCP server documentation - Apify MCP client - Model Context Protocol documentation - TypeScript tutorials in Academy - Apify SDK documentation ## Getting started For complete information see this article.
