Exa Agent requires authentication (OAuth or an API key).
Agent Skills
Skills live in skills/ and load with Agent Plugin / Claude plugin installs.
| Skill | Path | Use when |
| --- | --- | --- |
| search | skills/search/ | Deep research, lead gen, competitive analysis, multi-step web investigation |
| exa-agent | skills/exa-agent/ | Exa Agent runs, enrichment, structured output, Connect providers |
Invoke from your client's skill UI (or /skill-name where supported). MCP-only setups still get the tools; skills add orchestration on top.
Authentication
The hosted MCP server works anonymously with rate limits. For higher limits and access to Exa Agent, use either OAuth or an API key.
OAuth is preferred: most clients prompt you to sign in to Exa. To force the login flow (useful for shared connectors and plugins), use https://mcp.exa.ai/mcp?login or https://mcp.exa.ai/mcp/oauth.
If you prefer, you can get an API key from the dashboard and pass it on the URL as ?exaApiKey=…. You can also send it as a Authorization: Bearer … header or an x-api-key header.
