stillindexed_bulk_checkIndexability check for up to 20 URLs in one call.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Indexability check for up to 20 URLs in one call. Order preserved. Invalid URLs become per-row errors; HTTP status stays 200. Counts against the 60 fetches/hour budget, one per URL.

- openWorldHint: true

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check robots.txt for the 13 tracked AI crawlers (ChatGPT search, Claude, Perplexity, Gemini grounding, and the training crawlers) and report, per crawler, whether the given URL's path is allowed or blocked, naming the deciding group and rule. Also probes the edge once as each of the three AI search crawlers (OAI-SearchBot, Claude-SearchBot, PerplexityBot) against a browser request. Costs up to 5 fetches. Same check as https://stillindexed.com/tools/ai-crawler-checker.

Anlyon alternative

5 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
