SchemaPin Verification

Verify the cryptographic integrity of MCP tool schemas to ensure they haven't been tampered with.

Verification Process

Identify the MCP server to verify (from the extension manifest or the user's request)
Use the symbi__verify_schema tool to check the schema
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

Note on Tool Names

In Gemini CLI, MCP tools are prefixed with the server alias and double underscore. The symbi MCP tools are accessed as symbi__verify_schema, symbi__list_agents, etc.
