Frequently asked questions

What is Contract Guard?

Deterministic JSON Schema validation with exact violations and conservative type normalization.

How do I install Contract Guard?

It runs as a remote server. In Claude Code: claude mcp add --transport http contract-guard 'https://contract-guard-production.up.railway.app/mcp' --header 'X-API-Key: <Contract Guard API key. Free trial keys are available from https://contract-guard-production.up.railway.app/v1/trial-keys?source=mcp-registry>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Contract Guard need an API key?

Yes. It expects X-API-Key, which you set in its configuration.

Who maintains Contract Guard?

It is published by othepro211. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
