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 / HTTP

Requirements

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 to model_inferred and taint to mcp_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.
