Parameters from the server's own tool schema.
This tool is a discovery/search tool that retrieves and returns information about available tools — their names, descriptions, and schemas. It has no side effects, does not modify any data, and purely queries a catalogue of tools. Severity is low because misuse can only expose tool metadata.

Find tools by describing the data or task. Use when you need to browse, search, look up, or discover what tools exist for: SEC filings, financials, revenue, profit, FDA drugs, adverse events, FRED economic data, Census demographics, BLS jobs/unemployment/inflation, ATTOM real estate, ClinicalTrials, USPTO patents, weather, news, crypto, stocks. Returns the top-N most relevant tools with names, descriptions, and full input schemas (with curated examples) — each result is ready to call directly, no second schema lookup needed. Call this FIRST when you have many tools available and want to see the option set (not just one answer). It is categorised as a Read tool in the Mcp Horoscope MCP Server, which means it retrieves data without modifying state.
discover_tools accepts 6 parameters: q, task, limit, query, search, description. Required: query. The full parameter table on this page comes from the server's own tool schema.
