Tools

• discover_capabilities ~404 tokens
  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
• get_entry ~386 tokens
  Before calling a known service, check it is live right now and get its exact contract. 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
• list_categories ~202 tokens
  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
• list_entries ~503 tokens
  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 'pag
• search_registry ~583 tokens
  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_
• submit_entry ~1859 tokens
  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.
