"XState" matching MCP servers:

Enables agents to construct SHA-256 Merkle trees, generate and verify state inclusion proofs, validate JWT HMAC signatures, perform Schnorr zero-knowledge proofs, and enforce nonce replay protection for immutable state attestation.

Enables Claude to drive a gated incident-response runbook that enforces step order and logs all actions via an XState machine.

Enables a locally hosted AI, running entirely inside the client's building with no outside network access, to reach line-of-business systems, document stores and email through a small set of narrow, task-specific and schema-validated tools. It applies least-privilege per-tool credentials, personal-data masking, output leak checks and tamper-evident audit logging, keeping actions read-only by default and gating any write behind human approval so untrusted document content cannot trigger privileged operations.
