Community signal: 3 GitHub stars.
What problem does it solve?
Long policy prompts in every agent turn waste tokens and still fail to block disallowed tool calls at execution time.
Who is it for?
Indie builders running multiple MCP tools who need consistent enforcement before production agent workflows go live.
Skip if: Teams that only need one-shot code review without ongoing agent runtime control.
What do I get? / Deliverables
Governance rules can gate agent actions at the MCP runtime layer so shipping automated workflows stays within defined boundaries.
- Runtime policy enforcement layer for agent tool calls
- Reduced reliance on verbose in-context safety instructions
- Auditable gate between LLM plans and MCP execution
