# SchemaPin Verification
Verify the cryptographic integrity of MCP tool schemas to ensure they haven't been tampered with.
## Verification Process
1. Identify the MCP server to verify (from .mcp.json or the user's request)
2. Use the `verify_schema` tool from the symbi MCP server to check the schema
3. Report the verification result:
- **Verified**: Schema signature matches the publisher's key
- **TOFU**: First-time use, key has been pinned for future verification
- **Failed**: Schema has been modified since signing — DO NOT USE
- **No signature**: Schema is unsigned — warn the user about risks
## When to Verify
- Before first use of any new MCP tool
- After updating MCP server configurations
- When security audit is requested
- When a tool returns unexpected results
