Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (3)

`get_service`read-only	Inspect one enabled public SignalHarness service before invoking it. Use an exact service_id returned by list_services. This free, read-only call returns the canonical description, input and output schemas, price, endpoint, and supported payment metadata when available; an unknown or disabled ID returns a normalized not-found error.
`invoke_service`	Run exactly one enabled public SignalHarness service with caller-supplied input. Call get_service first and validate input against its input_schema. An unpaid call returns the canonical x402 V2 PAYMENT-REQUIRED challenge plus the equivalent x402 V1 JSON challenge; a client can then retry once with payment in params._meta["x402/payment"]. The server never retries automatically. A paid call may settle the advertised charge and perform external work, then returns service-specific structured JSON or a normalized error.
`list_services`read-only	Discover the currently enabled public SignalHarness service catalog before choosing a service. This free, read-only call takes no arguments and returns a compact service array with canonical IDs, descriptions, prices, and supported payment metadata. Results follow the canonical catalog order; compare services by their exact service_id.

Schemas: list_tools.
