pin_tool_surface — Compute a stable digest over an MCP server's tools/list — each tool's name, description and inputSchema — and return a signed attestation.
check_tool_surface_drift — Compare an MCP server's current tools/list against a baseline digest you hold and return a signed attestation naming every tool added, removed or silently redefined since then.
check_tx_finality — Read a Base transaction's receipt and return a signed settlement statement: succeeded or reverted, every USDC transfer it carried, block time, confirmations, and whether the block is safe or finalized by the chain's own tags.
check_ai_permission — May a named AI agent fetch, or train on, a URL?
witness_keys — Fetch a counterparty's JWK Set (OIDC jwks_uri or web bot auth key directory) and return a signed record of every key by RFC 7638 thumbprint, its defects, and a set digest; pass your prior digest or thumbprints to be told whether the keys rotated and which.
read_url — Fetch a public page and return its title and extracted text, bound to signed evidence of the bytes it came from — URL, time, status, SHA-256 — so what you quote is traceable to what was served.
