Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_tool_status | Check whether an AI tool is still alive. Returns active, deceased, or acquired — with the date and cause if it shut down, and live alternatives if it did. Use this before recommending a tool to avoid suggesting one that no longer exists. | Read-only |
| compare_tools | Compare two AI tools side by side by their directory slugs. Returns each tool’s profile (pricing, rating, editorial verdict, lifecycle) plus the editor’s head-to-head verdict and bottom line when one exists for the pair. | Read-only |
| find_alternatives | Find curated alternatives to a given AI tool by its directory slug. If the tool has shut down, returns live replacements. Good for "what should I use instead of X" questions. | Read-only |
| get_tool | Get the full profile of one AI tool by its directory slug: description, pricing, key features, editorial verdict and rating, the date it was last human-verified, lifecycle status, and the official site URL. | Read-only |
| list_tools | List the top-rated active AI tools in a category or for a job role, optionally filtered by pricing. Good for "what are the best AI tools for sales" or "free tools in <category>". | Read-only |
| search_tools | Search the AI Tool Directory catalog (2,000+ AI tools) by keyword, use case, or category using hybrid semantic search. Returns ranked tools with slug, one-line description, pricing model, and rating. Use this to discover tools, then get_tool for full detail. | Read-only |
