Tool Invocation Metadata Capture And Serialization

Drop-in Treeship attestation for MCP tool calls

Unique: Captures metadata at the MCP protocol boundary, extracting tool name, arguments, caller, and timing information automatically without requiring tool-level instrumentation — enables uniform metadata collection across heterogeneous tools

vs others: More complete than manual logging because it captures all MCP context automatically; more standardized than ad-hoc logging because metadata is serialized in a canonical format
