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 (8)

xguard_discoverread-onlyFind the paid API catalog and buying instructions, plus explicit provider operations and input schemas.
xguard_executedestructiveExecute an explicit scoped provider operation, or a supported public-source outcome. intent:demo is free. Never infer a mutation from ambiguous text.
xguard_get_resultread-onlyRecover a paid public outcome with its payment identifier and original signed quote without execution or another payment.
xguard_preflightread-onlyInspect validation, scope and remaining capability budget without reserving, billing or executing. Execution rechecks everything.
xguard_quoteread-onlyInspect XGuard credit pricing for a capability, or obtain a signed x402 quote for a public outcome. Does not execute.
xguard_secretless_calldestructiveCall an allowed provider operation with a capability. Enforces scope, call/credit budget and billing before server-side credential injection. Writes require idempotency_key.
xguard_statusread-onlyRead observed execution/MCP metrics and configuration; empty observations do not imply uptime.
xguard_verify_receiptread-onlyVerify a ProofRail proof and optionally its bound x402 receipt and result digest. Signature validity does not prove source truth.

Schemas: list_tools.
