Tools of Agent Nexus
	Description		Read-only	Idempotent	Open world
`discover_capabilities`Call this first whenever a task needs an external service (email, payments, search, storage, LLMs, data...) or when a service you use is failing. Maps a plain-language goal (e.g. 'send a transactional email') to callable APIs, MCP servers or CLIs. Returns matches[] with slug, endpoint, auth, formats, rate limit, pricing and a 0-100 reliability score; if nothing fits, coverage='none' and matches[] lists reliable starting points. Rate limits: 100 calls/day anonymous, 1,000/day with a free key, 50,000/day on Agent Pro. For a known keyword or slug, use search_registry.

`get_entry`Fetches the full record of ONE approved registry entry whose exact slug you already have, e.g. from a previous discover_capabilities, search_registry or list_entries result. Read-only and idempotent: the same slug always returns the same entry until its health probe changes. Returns {entry} with endpoint, auth mode and parameters, input/output formats, rate limit, pricing, capabilities, docs URL, invocation example and the latest health probe (hourly for priority entries, otherwise on a rolling daily cycle) — the detail level the listing tools omit. This is the single-record lookup: it takes no filters and no paging. If you do not have a slug, do not guess one — use search_registry for a keyword or discover_capabilities for a plain-language need; to walk the whole catalogue use list_entries. An unknown or unapproved slug is an error, not an empty result.

`list_categories`Return the fixed taxonomy of Agent Nexus: the three interface layers it indexes ('api', 'mcp', 'cli'), each with a label, a one-line definition and its live count of approved entries. Read-only, idempotent and parameterless — call it once to learn the exact values accepted by the 'category' argument of search_registry, list_entries and discover_capabilities, and to size the catalogue before paging. It never returns entries themselves: use list_entries to enumerate a layer, search_registry for a keyword, discover_capabilities for a plain-language need.

`list_entries`Enumerate the whole approved catalogue in deterministic slug order, page by page — use this when you want everything (mirroring, auditing, building your own index), not when you are looking for something specific. Read-only and idempotent. Returns {total, page, per_page, pages, results[]}: read 'pages' from the first response and increment 'page' until you reach it; 'total' and 'pages' reflect the 'category' filter when one is set, so keep the filter identical across pages or the paging shifts. Entries come back in summary form; call get_entry with a slug for the full record. For a keyword use search_registry, for a plain-language need use discover_capabilities, and for the accepted category values call list_categories. Bulk mirror alternative: GET https://agentnexus.app/api/public/entries.ndjson streams the full catalogue in one request.

`search_registry`Keyword lookup in the Agent Nexus registry when you already know what to look for: a product name, vendor, slug or endpoint fragment, optionally narrowed to one category. Matches literal text only — it does not interpret a goal. To go from a plain-language need to a callable interface, use discover_capabilities instead; to walk the whole catalogue in order use list_entries, and for the full record of one known slug use get_entry. Read-only and side-effect free. Returns {count, results[]} where each result is a summary entry record (slug, name, category, summary, endpoint, trust fields). Results are ordered alphabetically by name, not by relevance; there is no pagination beyond the limit parameter — raise limit (max 50) or narrow the query to see more. An empty results[] when nothing matches is a valid answer, not an error.

`submit_entry`Register a new interface (HTTP API, MCP server or CLI) in the Agent Nexus catalogue. Callers authenticate either as a signed-in member or with a free agent key (POST https://agentnexus.app/api/public/keys), which allows one submission per key and per source address per 24 hours. This is a write: it creates a pending row, it does NOT publish anything — every submission is reviewed by a human before it becomes discoverable, so nothing you send here is visible to other agents until it is approved. Nothing is overwritten or deleted, and re-submitting the same name creates a second pending row rather than updating the first. Five fields are required (name, category, summary, endpoint, auth_mode); everything else is optional but directly decides whether the entry is approved and how well it ranks: capabilities[] is what other agents are matched against, so list concrete verbs, and docs_url plus invocation_example are what a reviewer checks first. Rate limited to 20 submissions per hour for members and 1 per 24 hours per agent key and per source address, and the endpoint must answer a live health probe to keep a reliability score. Returns {slug, status}; poll GET https://agentnexus.app/api/public/submission?slug=<slug> for the decision, or pass contact_email to be emailed instead. Use list_my_submissions to review what you already submitted; use search_registry first to check the interface is not already listed.
