Live reliability for AI agent tools: is it working right now, and how do I call it correctly?

Find LIVE tools that can accomplish a task you describe in plain language — call this when you do NOT yet know which tool to use. Unlike find_alternatives / find_related_tools (which need a tool id you already have), this takes a free-text capability query (e.g. 'send a slack message', 'convert currency', 'search arxiv papers') and returns ready-to-use tool ids ranked by semantic similarity, filtered to tools that are live right now — each result carries the tool's advertised input schema, its actual connection endpoint (the MCP endpoint URL, or the package to launch for stdio servers), and whether it is FREE or PAID with the price + how to pay — so you can invoke it immediately without a second lookup or an MCP-registry search (on-demand / MCP-Zero style tool discovery). The discovery entry point at the start of a new task.

Parameter	Type	Description
limit	number	Max results (default 8, max 25).
query*	string	Plain-language description of the capability you need (e.g. 'send an email').
category	string	Optional capability category to narrow results.

Every field above is reproduced as the server published it at the time shown. The description and the annotations are claims by the server's author. Toolpin does not call tools, so we cannot tell you whether a tool does what it says.

What we can tell you is whether the claim changed. The hash covers the fields the MCP specification defines, so a vendor build stamp does not move it but a rewritten description does. See how we monitor, or this server's change history.
