search_agents

Advertised by the server during the last successful anonymous check.

Search the Agent Index open dataset of GRC, security, and operations AI agents. Defaults to the main GRC directory. Named products from the agent-security catalog are returned as a separate agent_security group. Pass segment=agent-security for that catalog only, or segment=all for both. Returns canonical theagentindex.io URLs. Not a ranking.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http agent-index-mcp-theagentindex https://theagentindex.io/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add agent-index-mcp-theagentindex --url https://theagentindex.io/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable agent-index-mcp-theagentindex in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "agent-index-mcp-theagentindex": {
      "url": "https://theagentindex.io/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "agent-index-mcp-theagentindex": {
      "type": "streamableHttp",
      "url": "https://theagentindex.io/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start agent-index-mcp-theagentindex and inspect its tools.

VS Code configuration

{
  "servers": {
    "agent-index-mcp-theagentindex": {
      "type": "http",
      "url": "https://theagentindex.io/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http agent-index-mcp-theagentindex https://theagentindex.io/api/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

      "url": "https://theagentindex.io/api/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
