Setup
Install RapidTools Validate in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/tailored-tools/rapidtools-mcp-server
Follow the installation instructions in the repository README, then restart your MCP client.
MCP server forRapidTools— deterministic JSON Schema validation with signed attestations.
Exposes three tools to any MCP-compatible client (Claude Code, Cursor, Cline, VS Code Copilot):
- validate— Validate a JSON payload against a JSON Schema. Returns a signed attestation.
- verify— Verify the cryptographic signature of a previous attestation.
- get_attestation— Retrieve a stored attestation by ID.
Every validation is deterministic (same inputs = same result), idempotent, and cryptographically signed.

Validate data against a JSON Schema and get a signed attestation.
Input: schema (object, required) — JSON Schema (Draft 2020-12 subset) payload (any, required) — Data to validate metadata (object, optional) — Key-value pairs to attach idempotency_key (string, optional) — For deduplication Output: attestation_id — Unique attestation identifier valid — true/false errors — Array of validation errors (if any) schema_hash — SHA-256 of the schema payload_hash — SHA-256 of the payload signature — HMAC-SHA256 cryptographic signature timestamp — ISO 8601 timestamp
Verify that an attestation signature is valid and untampered.
Input (option A): attestation_id — ID of a stored attestation Input (option B): id, schema_hash, payload_hash, valid, created_at, signature — Full attestation record Output: attestation_id — The verified attestation ID signature_valid — true/false
Input: attestation_id — The attestation ID to retrieve Output: Full attestation record including signature and metadata
