bluerock vs SchemaPin

bluerock: BlueRock is a lightweight runtime security sensor for Python MCP servers. It monitors MCP tool calls, resource access, session lifecycle, and module imports with zero code changes, emitting structured NDJSON events for every operation.; SchemaPin: SchemaPin enables tool developers to sign schemas and skill folders with ECDSA P-256 keys, and AI agents to verify schema integrity. Public keys are discovered via .well-known/schemapin.json, and Trust-On-First-Use pinning prevents key substitution. It supports key revocation, trust bundles, and multiple languages (Python, JS, Go, Rust).
