TrueFoundry

TrueFoundry AI Gateway is an enterprise-grade proxy layer between your applications and LLM providers or MCP servers. It provides unified access to 1,000+ LLMs with centralized observability and governance. TrueFoundry provides Exa as an official remote server in its MCP Gateway. Connect the Exa MCP server to give your teams one managed endpoint for web search, content fetching, and agentic research.

Add Exa to TrueFoundry

Open MCP Servers in the TrueFoundry sidebar and select Add new MCP Server.
Select Connect Official Remote MCP Servers.

TrueFoundry's Add MCP Server picker with Connect Official Remote MCP Servers selected — Choose the official remote MCP server catalog

Find Exa in the catalog and select + Add.
Confirm the pre-filled server details:

Field	Value
Name	`exa`
Description	Search Engine made for AIs by Exa
URL	`https://mcp.exa.ai/mcp`
Authentication	Optional (The MCP Server works without authentication. You only need an Exa API key if you reach the free rate limit.)

Add the users or teams that should manage or use the server. Leave Auth Data off, then select Update MCP Server.

Exa MCP server registration form with its name, URL, collaborators, and authentication settings — Configure the Exa server and its collaborators

Open the Tools tab and confirm that Exa’s search, content fetching, and agentic research tools are available.

Configure the Exa server

The pre-filled URL exposes Exa’s default toolset. Change it only if you need to restrict the available tools or use your own API key.

Choose which tools are available

Pass a comma-separated list of tool names in the tools query parameter:

https://mcp.exa.ai/mcp?tools=web_search_exa,web_fetch_exa,agent_tools

You can enter the URL in the server form or use Apply using YAML:

url: >-
  https://mcp.exa.ai/mcp?tools=web_search_exa,web_fetch_exa,agent_tools
name: exa
type: mcp-server/remote
description: Search Engine made for AIs by Exa
collaborators:
  - role_id: mcp-server-manager
    subject: user:you@your-company.com

You can find available tool names in the Exa MCP documentation.

Use your Exa API key to bypass the free rate limit

If you reach the free rate limit, add your Exa API key to the server URL:

https://mcp.exa.ai/mcp?exaApiKey=YOUR_API_KEY

Get your Exa API key

Connect an MCP client

Open the Exa server’s How To Use tab and select your client. TrueFoundry generates the tenant-specific endpoint and ready-to-paste configuration for Cursor, Claude Code, VS Code, Windsurf, Codex, and other MCP clients.
