Common questions
Is Gatekeeper safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed 36 days ago, and the latest version (0.1.2) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Runestone Gatekeeper — MCP Server
An MCP server that lets any MCP client (Claude Desktop, Claude Code, Cursor, …) run real tool calls — shell, file writes, HTTP, or any Gatekeeper tool — only through [Runestone Gatekeeper](https://github.com/Runestone-Labs/gatekeeper). Every call is policy-checked, may require human approval, and is audited. The model never touches your systems directly; Gatekeeper sits in front.
MCP client (LLM) ──tools/call──▶ gatekeeper-mcp ──policy-gated──▶ Gatekeeper ──▶ shell / files / HTTPRequirements
A running Gatekeeper server (see the repo root). This package is just the MCP front door; it does nothing on its own.
Install / configure
It runs over stdio. Add it to your MCP client config, e.g. Claude Desktop (claude_desktop_config.json):
{"mcpServers": { "gatekeeper": { "command": "npx", "args": ["-y", "@runestone-labs/gatekeeper-mcp"], "env": { "GATEKEEPER_URL": "http://127.0.0.1:3847", "GATEKEEPER_ROLE": "openclaw" } } } }
| Env | Required | Default | Meaning |
|---|---|---|---|
GATEKEEPER_ROLE | yes | — | The policy role this server presents to Gatekeeper for every call. |
GATEKEEPER_URL | no | http://127.0.0.1:3847 | Gatekeeper base URL. |
GATEKEEPER_AGENT_NAME | no | mcp-client | Name recorded in audit logs. |
Shared approvals for unattended agents
Local Gatekeeper and this MCP integration are free. Need a teammate to handle approvals while your agents run unattended? We're testing Gatekeeper Team at $49/month, for up to five members and five instances. The proposed Cloud service would coordinate a held action, a teammate's approval or denial, and a record of the outcome. Cloud is planned, not publicly available, and no payment is collected during this test. Only actions actually routed through Gatekeeper are covered; installing the MCP server does not cover a client's other tools.
See the proposed workflow and share your team's needs. The form also lets you optionally report a first real routed action or return use on a later day. These are manual self-reports, not verified external activation. Don't send commands or raw audit logs; this test adds no automatic usage reporting to the MCP server.
Tools
| Tool | Gatekeeper tool | Use |
|---|---|---|
shell_exec | shell.exec | Run a shell command. |
files_write | files.write | Write a file. |
http_request | http.request | HTTP GET/POST (egress-policed). |
gatekeeper_call | *(any)* | Generic escape hatch — call any Gatekeeper tool (e.g. memory.query) by name. |
gatekeeper_health | — | Check the Gatekeeper server is reachable. |
Every gated call returns one of:
- allow → the tool output.
- deny → an *error* result explaining why (the call did not run).
- approve → an *error* result saying a human must approve it in Gatekeeper; the call did not run.
Security model
This server is a policy boundary, so it is deliberately strict:
- Identity is pinned server-side. Role comes from
GATEKEEPER_ROLE; origin is fixed tomodel_inferredand taint tomcp_client. The MCP client cannot set or override actor / role / origin / taint / capability tokens via tool arguments — there is no code path from a tool argument to any of those. - Fail closed. A deny, a pending approval, or *any* malformed/unexpected Gatekeeper response is surfaced as an error — never as a successful result.
- No endpoint traversal. Generic tool names are validated as strict dotted identifiers;
../, slashes, and the like are rejected before any request. - No leakage. The Gatekeeper URL and anything resembling a credential are scrubbed from error messages before they reach the client.
These invariants are covered by an adversarial test suite (src/*.test.ts).
Distribution
Published to npm as @runestone-labs/gatekeeper-mcp and listed on the MCP Registry as io.github.runestone-labs/gatekeeper (see server.json). The MCP Registry is in preview.
