Exa MCP Server for Zed
A Zed extension that connects Zed's Agent Panel to Exa's hosted MCP server (https://mcp.exa.ai/mcp) via mcp-remote, giving your agent web search, page fetching, and Exa Agent tools.
Install
Open Zed's Extensions view (zed: extensions), search for Exa, and click Install.
Tools
Enabled by default:
Available via the tools setting:
Note: setting tools replaces the defaults entirely — list every tool you want enabled.
Configuration
Add an exa_api_key and/or tools under the server's settings in settings.json:
{
"context_servers": {
"mcp-server-exa-search": {
"settings": {
"exa_api_key": "YOUR_API_KEY",
"tools": "web_search_exa,web_fetch_exa,agent_run"
}
}
}
}
Authentication
The hosted server works anonymously with rate limits — no key required for web_search_exa and web_fetch_exa. An API key from dashboard.exa.ai/api-keys raises your rate limits and unlocks agent_run (Exa Agent). The key is passed to the server as ?exaApiKey=.
Without the extension
Zed natively supports remote MCP servers (with OAuth), so you can skip the extension entirely and add this to settings.json:
{
"context_servers": {
"exa": {
"url": "https://mcp.exa.ai/mcp"
}
}
}
Using it in the Agent Panel
Open the Agent Panel settings and check the indicator dot next to the Exa server — green means it's running. Tools can be toggled per agent profile. See the Zed MCP docs for details.
