MCP server

Legible, inside your AI client

Legible is a Model Context Protocol server. Connect it to Claude, Cursor, or any MCP-capable assistant and score how findable, citable, and buyable any brand is to AI — without leaving the chat. A company built to make you legible to agents should be callable by them.

Streamable HTTP · no API key required.

Connect

Most MCP clients accept a remote URL directly. Add Legible to your client config:

{
  "mcpServers": {
    "legible": { "url": "https://legibleindex.com/api/mcp" }
  }
}

· Claude Desktop — Settings → Developer → Edit Config (claude_desktop_config.json), then restart.
· Cursor — Settings → MCP → Add server, paste the URL.
· Other clients — use the URL anywhere a remote MCP server is accepted.

If your client only supports local (stdio) servers, bridge it:

npx mcp-remote https://legibleindex.com/api/mcp

Unlock the Pro tools (full Fix Pack, Share-of-Voice, Verification, Deep Audit) — generate a token in your account and send it as a bearer header:

{
  "mcpServers": {
    "legible": {
      "url": "https://legibleindex.com/api/mcp",
      "headers": { "Authorization": "Bearer lgbl_…" }
    }
  }
}

Once connected, ask your assistant:

“Use Legible to score stripe.com — what should they fix first?”
