MCP Observatory

What it does

MCP Observatory is a professional security and reliability suite for developers building MCP servers. It allows teams to catch broken tools, unsafe schemas, and security vulnerabilities before they are deployed into production agent environments.

Tools

• scan: Auto-discovers servers and runs security/health checks.
• check_server: Tests a specific server for reliability.
• score_server: Provides a health grade (0-100) for a server.
• record/replay/verify: Implements a VCR-like workflow for regression testing MCP tool calls.
• diff_runs: Detects schema drift between different versions of a server.
• suggest_servers: Recommends MCP servers based on the project's technology stack.
