Marrow AI MCP Server

`@getmarrow/mcp`: the control layer for AI agents. Marrow AI puts a named yes on an action before your agent acts, and leaves proof the next agent can reuse.

**Which Marrow?** This is Marrow AI from [getmarrow.ai](https://getmarrow.ai) (npm `@getmarrow/mcp`, MCP Registry `ai.getmarrow/marrow`). It is not affiliated with marrow.id, HyperMarrow, marrow.works or other projects named Marrow.

Marrow AI is the runtime control and proof layer for teams running AI agents. It applies policy and prior lessons before consequential actions, then records the evidence and outcome afterward.

Use `@getmarrow/mcp` when your agent client supports the Model Context Protocol and you want Marrow available inside the agent's normal workflow. It works with Claude Code, Claude Desktop, Cursor and other MCP-compatible clients without replacing the model or harness.

Quick start

**Create a key.** Sign up at [getmarrow.ai/signup](https://getmarrow.ai/signup), then open the dashboard, go to **API keys** and choose **Create API key**. The key is shown once.
**Activate.** Make the key available as `MARROW_API_KEY` (from your secret storage, or an owner-only `~/.marrow/env`), then run the installer from a terminal:
```
npx -y @getmarrow/install@latest activate
```
Fallback if you cannot set the key first (a key typed on a command line stays in your shell history): `MARROW_API_KEY= npx -y @getmarrow/install@latest activate`.
**Restart** the agent hos
