AgenticWebScore

AgenticWebScore MCP server

Scan a public website for AI agent readiness: 60 checks, a score, and the evidence for each.

AgenticWebScore measures how well a public website serves AI agents. One scan runs 60 checks from the outside, the way a crawler or an agent reaches the site:

• robots.txt and AI crawler rules;
• sitemaps, headings and structured data;
• HTTP caching and real 404s;
• markdown negotiation and llms.txt;
• OpenAPI and MCP servers.

Each check returns its status, the evidence it read, the source it follows, and a shell command that repeats the measurement. The score is 70% adopted web standards and 30% agent conventions, and every record carries a fingerprint you can verify.

This repository holds the listing files for the hosted server: this README, server.json for the official MCP Registry, the logo and client configs. The server itself runs at https://agenticwebscore.com/mcp.

Connect

• Transport: Streamable HTTP. The server is stateless: one JSON-RPC message per POST, no session, and GET answers 405.
• Authentication: none. No API key and no sign-up.
• Protocol versions: 2025-11-25 and 2025-06-18.

Claude Code:

claude mcp add --transport http agenticwebscore https://agenticwebscore.com/mcp

Any client that reads an mcpServers file:

{
  "mcpServers": {
    "agenticwebscore": {
      "type": "http",
      "url": "https://agenticwebscore.com/mcp"
    }
  }
}

Gemini CLI, as an extension (gemini-extension.json):

gemini extensions install https://github.com/marifeting/agenticwebscore-mcp

This repository is also a Cursor plugin (.cursor-plugin/plugin.json and mcp.json) and carries a LobeHub manifest (lhm.plugin.json). All of them point to the same remote endpoint.

Tools

Tool	What it does	Annotations
scan_site	Scans a public domain and returns the full record: the score and its two parts, the level, each check's status and evidence, and the fingerprint. A stored record younger than 6 hours is returned without a new scan, unless fresh is true.	not read-only, open world
get_score	Returns the stored record for a host. Starts no scan.	read-only
list_checks	Lists the 60 checks of rubric v0.9 with their kind, module, dimension and rationale.	read-only
get_report	Returns the markdown report of a stored record, or one check of it. Starts no scan.	read-only

Example prompts

• "Scan example.com for agent readiness and list the checks that failed."
• "What does example.com's robots.txt say to GPTBot and ClaudeBot?"
• "Read the stored AgenticWebScore report for cloudflare.com and explain its MCP result."
• "Which of the 60 checks are about llms.txt, and how is each scored?"

Limits

• A new scan counts against 10 per client per minute and 3 running at once.
• A scan runs for up to 60 seconds. If a call times out first, the scan still finishes and is stored.
• A scan sends only GET requests to the site, apart from an MCP handshake (initialize and tools/list) when the site runs an MCP server. It never calls that server's tools.
