MCP server for RapidTools — deterministic JSON Schema validation with signed attestations
Rapidtools MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCP server for RapidTools — deterministic JSON Schema validation with signed attestations.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Once Rapidtools is connected, these are the calls the assistant has available:
Cursor — The Cursor tool exposed by this servervalidate — Validate data against a JSON Schema and get a signed attestationverify — Verify that an attestation signature is valid and untamperedget_attestation — Output: Full attestation record including signature and metadataYou will need 2 environment variables: RAPIDTOOLS_API_KEY, RAPIDTOOLS_API_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Rapidtools's toolset — Cursor, validate, verify and 1 more — is a fair guide to whether it matches your workflow. It is maintained by tailored-tools; worth a glance at recent repository activity before you build anything load-bearing on it.
