Use cases

• Enforce access control policies on MCP tool invocations
• Audit and log tool usage in AI agent pipelines
• Apply rate limiting or validation rules to MCP tool calls

Pros

• Lightweight Python implementation that slots into existing MCP setups
• Focuses specifically on governance without overcomplicating the protocol layer
• Open source with potential for custom policy extensions

Cons

• Zero stars on GitHub indicates very limited community adoption and testing
• Documentation and sample usage are minimal based on repository status
• Requires familiarity with MCP protocol to configure effectively
