    searchSearch Index Agentica: the directory of agent-usable resources (skills, harnesses, MCP servers, tools, protocols, APIs, information sources, finance/payments, directories) plus its long-form content (guides, comparisons, stacks and downloadable Agent Skills). Matches the query words against name/title, id, tags, summary and description and returns the best matches first, each with its type, a relevance score and links (HTML, markdown, JSON). Optionally filter by type (entry, guide, comparison, stack, skill; default all), category (entries only) and/or tags (ALL given tags must match). An empty query with a filter lists everything in that filter. For full details use get_entry for type entry, or get_content with the type and id for long-form items.
    get_entryFetch one Index Agentica entry by its id (kebab-case slug, e.g. "model-context-protocol"). Returns every field: name, category, summary, description, url, repo, docs, tags, license, pricing, status, agent_access (llms_txt, openapi, mcp_endpoint, auth), related ids, sources, dates and links. If the id is unknown the result is an error with suggested ids.
    get_contentFetch one Index Agentica long-form item by type and id (as returned by search). Returns its metadata (title, summary, author, tags, dates, referenced entries with links, related items, sources, links) and its markdown (scheme links resolved to absolute URLs). Comparisons include the structured table (criteria, one row per entry, verdict); stacks include the use case and components; skills include the full SKILL.md (skill_md) plus download links (links.zip, links.skill_md). Unknown ids return an error with suggestions.
    list_categoriesList all Index Agentica categories with their slug, name, description, entry count and links (HTML page and JSON). Use a slug as the category filter for search.
