Read-only status lookup for public ProofRelay discovery metadata. Use first to confirm the hosted MCP endpoint, server-card URL, product URL, public tool count, and trust boundary. Requires no authentication, performs no network call from this local wrapper, mutates nothing, and returns JSON text with status, URLs, counts, and non-confidential boundary notes.

Read-only checkpoint recommendation for a high-level agent action class. Use before relied-upon actions such as paid_tool_call, revenue_action, external_reliance, or financial_transaction; use get_verifier_status for discovery only and verify_bundle after evidence metadata exists. Requires no authentication, mutates nothing, and returns JSON text with status pass, skipped, or needs_review plus checkpoint and reason fields.

Read-only public-safe bundle shape check for synthetic or non-confidential evidence metadata. Use when you already have a bundle fixture and need a local pass/fail boundary check before sharing or routing to hosted verification; use recommend_checkpoint when deciding whether a checkpoint is needed. Requires no authentication, mutates nothing, does not certify real-world facts, and returns JSON text with status, checks, problems, verifier, and hosted endpoint fields.

Read-only advisory scan of caller-supplied public MCP descriptor metadata. Use before registering or trusting an MCP server to flag mutating tools, payment or wallet language, credential signals, or missing public metadata; use verify_bundle for evidence bundles instead. Requires no authentication, does not fetch server_url, mutates nothing, is not a security certification, and returns JSON text with status, findings, recommended_control, non_claims, and boundary fields.

Read-only integration guide for the invisible pass/fail/review helper pattern. Use when an agent or developer needs to understand how to wrap actions with ProofRelay-style checkpoint statuses; use recommend_checkpoint for a specific action decision. Requires no authentication, mutates nothing, and returns JSON text describing statuses, hosted endpoint, and the action-to-audit flow.
