The real catalog of tools for AI agents

MCP server for verifying receipts: POPCORN-WITNESS/2.0 signature, digest, and time. Free, read only.

MCP server for signed time and witness receipts. Prove when an agent action happened. Verify free.

Witness: agreed terms, delivery checks, signed receipts, dispute bundles and evidence packs.

Production proofs for breaking JSON Schema/MCP changes; UNKNOWN/NO_WITNESS_FOUND not compatible.

A witness layer for AI agent tool calls.

Distills your sessions or any text corpus into a dated history of how its subject changed.

Verify VerixID proof-of-existence records and optionally prove ownership.

Agent leases, signed receipts, watchdogs, and optional paid source-verification evidence.

Verifies legal citations vs primary sources: existence, quote match, proposition support.

Stamp or notarize data into a public witnessed transparency log. Proves timing, not truth.

Now part of GAIP Witness: tests supplier claims and compares them with published metadata.

One API, all things verified — control, delegation, human approval, anti-impersonation.

Evidence-backed web verification for agents with deterministic JSON, text evidence, and screenshots.

Timestamp & verify evidence on-chain, free. Proofpack: a portable BEEF+BUMP proof bundle per txid.

Cryptographically anchored evidence for agents: verified run receipts, proof-gated settlement.

Now part of GAIP Witness: verifies GAIP receipts; evidence packs and incident bundles.

Verify timestamp proofs offline, anchor hashes through ProofLedger, keep agent run receipts.

Verify emails, validate phone numbers, look up carriers and score IP addresses.

Remote-first MCP adapter for emitting Settlement Attestation Receipts; not a verifier.

Cryptographic AI governance and audit. 75 tools, 84 frameworks. EU AI Act, NIST, CMMC, MCP Top 10.
