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.

Endpoint

https://legibleindex.com/api/mcp

Streamable HTTP · no API key required.

Tools

score_brand(url)Free
The Legible Readiness Index (0–100) across 8 dimensions, a band, and prioritized gaps to fix.
get_fix_pack(url)Free preview
A guided preview of what to fix (structured data, llms.txt, robots, ai-facts, FAQ, hreflang). The full ready-to-paste pack and the deep modules live in the Legible web app.

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

Once connected, ask your assistant:

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