# schemadriftgate-mcp

Monitors agent tool schemas, blocks breaking interface updates, and logs release audits. Useful when automated pipelines depend on strict schema compatibility.

## What it does

The server guards agent workflows against unexpected interface shifts. It evaluates tool definitions using `check_schema_drift` and clarifies issues through `explain_breaking_change`. The gateway also tracks approvals and exports audit logs.

This is a hosted paid service. You will not find the application source code in the repository. Connecting requires Streamable HTTP client support and an `Authorization: Bearer <token>` header. Without an active account, requests to `https://schemadriftgate.clauxel.com/mcp` fail.

## When to use it
- Catch breaking tool definition drifts before agents trigger errors
- Approve new interface signatures with `approve_tool_schema`
- Inspect incompatibility details using `explain_breaking_change`
- Export release audit histories for pipeline compliance

## Example prompts
- Check our tool definitions for schema drift using schemadriftgate-mcp.
- Explain what broke in the latest tool schema update.
- Export the interface audit log for the current release.
