Matimo - An SDK with Meta-Tools, Policy Engine, and Human-in-the-Loop control. 200+ production tools, self-extending agents with enterprise-grade governance. Works with LangChain, CrewAI, Claude MCP. Open source under MIT.
Hi everyone!
We built this while building Nova, our own agent platform, because every tool integration was one-off and nobody was thinking seriously about governance.
What's actually in the code today:
151 YAML tool definitions across 10 providers (Slack, GitHub, HubSpot, Notion, Gmail and more),
12 agent meta-tools that let agents propose new tools at runtime (with a human approval gate),
TypeScript + Python SDKs with ~4,200 tests, and framework converters for LangChain, CrewAI, and MCP.
The policy engine classifies every tool call before it runs — auto, approval-required, or blocked.
MIT. No usage caps.
Build on it, fork it, tell us what's missing.

Hope you enjoy today’s launch — and we'd love your feedback!
