Recorded tools

description — populates the schema's description field
schema — raw JSON Schema fragment that overrides the derived schema entirely (useful for enum constraints, patterns, or numeric bounds Scala types can't express)

More MCP options

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
Hint	Meaning
title	Human-readable display name (distinct from the wire-level name)
readOnlyHint	The tool only reads state; safe to call without confirmation
destructiveHint	The tool may irreversibly modify state; clients should confirm
idempotentHint	Repeated calls with the same args have the effect of one call
openWorldHint	The tool reaches outside the local process (network, filesystem, APIs)
returnDirect	Return the result directly to the user, skipping LLM post-processing
