Search the agentage MCP directory - a public catalog of Model Context Protocol servers crawled from the official registry - for servers matching a keyword, optionally narrowed by type, category, language, or license. Use this FIRST whenever the user wants to discover, find, compare, or pick an MCP server ("is there an MCP for X", "which MCP servers do Y"). Results are ranked by text relevance to the query first, then by popularity, so the best match is on top. Returns a page of lean cards (slug, title, description, category, transport, match_score - text relevance the ranking is based on, details_url). To read one server's full packages, tools, and install command, call mcp_get with the slug from a result; open a card's details_url for the human detail page. Valid category, language, and license values come from the mcp_categories tool, not from guesswork - call it before filtering and pass its labels verbatim, or the call is rejected. Read-only - never installs or runs anything.
Fetch the complete record for ONE MCP server in the agentage directory by its canonical slug: full description, categories, the packages and remote endpoints it ships, the tools it exposes, a ready-to-run install command, and a README excerpt. Use this after mcp_search to get the depth a result card omits - pass a slug exactly as returned by mcp_search. Slugs are canonical and registry-derived ("io-github-github-github-mcp-server"), NOT the plain product name ("github"); if you pass a plain name anyway it is resolved by search as a fallback - a single confident match returns that server (with `resolved_from` set), anything else returns an error naming the candidate slugs to retry with. No slug yet? call mcp_search first. Read-only.
List the directory's available filter values - every category, language, and license, each with how many servers carry it. Call this BEFORE mcp_search when you intend to filter, so you pass exact, existing values for the type/category/language/license arguments instead of guessing. Takes no input. Read-only.
