Open sourceSelf-hosted
What to know▼

Open sourceSelf-hosted
What to know▼
How it works

What's different
Open source and self-hostable, replacing guesswork with statistically grounded experiment results.
Best for
ML engineers trying to prove which changes to an AI pipeline actually improve quality.

MCP Boundary

Live

Sits between your AI agent and its MCP tools, blocking calls that break rules you write and telling the agent why instead of just failing — a policy layer for developers.

Self-hosted
What to know▼
How it works
Sits as a local checkpoint between an AI agent (e.g. Claude Desktop) and the MCP tools it calls, checking each routed call against rules you write before it runs.
What's different
When it blocks a call it sends back a short, machine-readable reason the agent can act on instead of just failing, and it can tie a write to the data the agent read first so a stale read forces a re-read before the write proceeds.
Best for
Developers who want a policy layer between an AI agent and the tools it's allowed to call.

What's different
Notes feed directly back into the coding agent's session rather than staying siloed in the review tool.
Pricing
Free, MIT / Apache-2.0 licensed, runs on your machine.
Best for
Developers reviewing large volumes of AI-agent-generated code across multiple version control systems.

Open sourceSelf-hosted
What to know▼

Best for
Teams and individuals who think visually and want an AI agent's output to live alongside their own notes and diagrams, not in a separate chat log.
