Index Agentica tools (4)
write = sends, deletes, buys or postsget_contentFreeFetch 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.
get_entryFreeFetch 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.
list_categoriesFreeList 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.
searchFreeSearch 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.

Endpoints
Errors are always JSON: {"error":{"status":400,"code":"badrequest","message":"..."}} (codes: badrequest, notfound, methodnotallowed, ratelimited, upstream_error).
MCP tools
Every tool has a JSON-Schema inputSchema, an outputSchema, readOnlyHint annotations, and returns both structuredContent and the same JSON as a text content block. Bad arguments and unknown ids come back as isError: true tool results (so the model can correct itself); an unknown tool name is JSON-RPC -32602.
Scoring: per query word, exact id/name match 12, id segment 6, name substring 5, exact tag 4 (partial tag 2), summary 2, category 1.5, description 1; +8 if the whole phrase is in the name; multiplied by the fraction of words matched.
