host.tool_run
shallowdev.mcphost/mcphost · Verify this server
Debug run of a published tool: the same sandbox and limits as a real call, but returns full stdout and stderr (each capped at 64 KiB) and the exit code alongside the result, and records no `calls` row and no metering. Only kinds with a notion of a subprocess (`python`) support this; other kinds return `tool_run_unsupported`. Rate-limited to 30 calls per tenant per minute, independent of `host.usage`.
