Inspect a site's AI-search readiness: AI crawler access, llms.txt, schema markup, meta directives
Overview
Local MCP server that lets an assistant inspect a website's AI-search readiness: AI crawler rules, llms.txt, schema markup and meta directives.
- What you can do
- Check robots.txt rules for AI crawlers such as GPTBot, ClaudeBot and CCBot, plus sitemaps
- Check whether a site publishes llms.txt or llms-full.txt and whether it is spec-valid
- Detect JSON-LD blocks, schema.org types and sameAs disambiguation on a page
- Read meta robots tags, including noai and bot-specific tags, and X-Robots-Tag headers
- Return a readable summary plus structured JSON for each check
- When to use it
- Useful when you want to know whether a site allows AI crawlers to train on or cite its content, or how well it is set up for AI search and citation. It suits quick audits of a few pages rather than bulk crawling.
- Requirements
- Runs as a local process over stdio, started with npx from the npm package geo-inspector-mcp, so Node.js and network access are needed. No accounts, API keys or environment variables are declared.
Installation
In SourceWeft
- Open GEO Inspector in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
README
geo-inspector-mcp
[npm] [MCP Registry] [license]
An MCP server that gives an AI assistant four tools for inspecting how a website presents itself to other AI systems: which AI crawlers it blocks, whether it publishes llms.txt, what schema markup it ships, and how its indexing directives are set.
Published on npm and listed in the official MCP Registry as io.github.Bigsupe55/geo-inspector-mcp. Works with Claude Code, Claude Desktop, or any MCP client.
[geo-inspector-mcp inspecting three sites]
Tool output above is verbatim from a live run against nytimes.com, docs.anthropic.com,
and stripe.com, captured by driving the built server over MCP stdio. The sitemap list is
collapsed to a count; nothing else is edited. Regenerate with npm run demo.
Why this exists
AI assistants are becoming a primary way people find and cite content, and sites signal their intent to AI systems through a handful of plumbing files: robots.txt rules for AI crawlers, the emerging llms.txt standard, schema.org structured data, and meta directives. Checking those by hand means juggling curl, a robots.txt parser in your head, and view-source. This server turns all of it into questions you can just ask Claude.
Quickstart
That is the whole install. Point your MCP client at it:
Claude Code
Claude Desktop (claude_desktop_config.json)
Then ask things like: "Which AI crawlers does nytimes.com block?" or "Does stripe.com publish an llms.txt?"
Tools
Every tool returns a readable summary plus structured JSON (structuredContent) for programmatic use.
How it is built
The interesting part of an MCP server is not the tools, it is the contract around them.
Every tool returns two things. A readable summary for the model to reason over, and
structuredContent for anything downstream that needs to compute. That split is what
lets a separate scoring layer (ai-visibility-audit)
derive deterministic numbers from the same call the model is reading in prose. The model
never has to parse its own tool output back into data.
Parsers are pure functions. robots.txt, llms.txt, JSON-LD, and meta directives
each parse in isolation, with no I/O and fixture-based tests. A tool handler is a thin
shell: fetch, parse, format. This is what makes the behavior testable without a network,
and it is why the test suite runs with no fixtures to record and no site to hit.
All network access goes through one helper. A single fetch path with a size cap, a redirect limit, and a timeout. An MCP server runs inside someone else's agent loop with their API budget attached, so a tool that can hang or stream an unbounded response is a tool that can ruin a session. One choke point means those limits cannot be forgotten in a new tool.
robots.txt parsing follows RFC 9309 rather than a regex, because the whole value of
the tool is being right about whether a specific crawler is allowed. Longest-match wins,
user-agent groups merge, and Allow can override a broader Disallow.
Development
Parsers are pure functions with fixture-based tests; all HTTP goes through one capped, redirect-limited fetch helper.
Regenerating the demo GIF
Or the steps separately:
demo-data.json is committed, so rendering works offline and the GIF's claims stay
auditable: diff it against what the tools return today. The capture script mocks
nothing, so if a site changes its robots.txt, the demo changes with it. The only
authored text in the pipeline is the human question line; the sites to inspect are
configured at the top of scripts/capture-demo.mjs.

ai-visibility-audit is the workflow layer on top of this one: it orchestrates these four tools into a scored, client-ready report. This repo is the raw tools.
