Tools of Agent Preflight
	Description		Read-only	Idempotent	Open world
`check_request`Validate an HTTP API request body against a supplied JSON Schema before sending it. This tool does not execute the request. Use it when an agent needs to determine whether a proposed JSON body satisfies its expected schema. Optional economics adds proceed/abort advice from expected waste versus a $0.002 check.

No	Yes	Yes	No
`preflight_tool_call`Free MCP decision for generic search:web_search or browse:fetch proposals only. Returns structuredContent and JSON text, never destination results. Caller supplies cost estimates, post-consultation budget and history, executes tools and retrieves resultReference itself. Reuse requires explicit permission, positive TTL and matching nonempty goal hashes; history must belong to the caller. estimated fees/savings are hypothetical, not receipts; confidence is not calibrated. Paid HTTP is a separate $0.002 per settled POST interface. Full contract: https://agent-preflight.com/docs	Free MCP decision for generic search:web_search or browse:fetch proposals only.
