# Discover live tool schemas

Collection: mcp
Human docs: https://zei.sh/docs/mcp

Use tools/list instead of hard-coding an outdated tool catalog.

Call tools/list after connecting. The response is the source of truth for names, descriptions, and JSON schemas exposed by the deployed server.
Tool results are returned as text content. Validate arguments against the schema returned by the server.

Example:

```
{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}
```
