AgentBridge MCP Server

Bridges GitHub webhooks + an AI coding agent's git actions to a mobile app, via phone-issued approve/commit/push/pull commands.

Setup

npm install cp .env.example .env # then edit ALLOWED_REPO_ROOT to point at your repo's parent dir npm run build npm start

Related MCP server: github-mcp-server

Endpoints

• POST /webhooks/github — point your GitHub repo webhook here (same secret as .env)

• POST /action — phone app calls this on Approve/Reject tap: { actionId, decision }

• GET /health — liveness check

• ALL /mcp — MCP endpoint for the AI agent (Claude Code, etc.) to call tools: git_status, get_diff, request_commit, request_push, request_pull

• WS /ws — phone app connects here to receive live action notifications

Important: ALLOWED_REPO_ROOT

The server refuses to run git commands outside this directory (path-traversal guard, tested). Set it to the folder that CONTAINS your demo repo, and pass the repo's folder name as repoPath in tool calls / webhook payloads.

Tested end-to-end (see conversation log)

• Real git status/diff/commit/push/pull against a live repo

• Path-escape rejection

• GitHub webhook HMAC signature verification (forged + valid cases)

• Full loop: MCP tool call -> phone WebSocket notification -> phone approves via /action -> real git push lands on the remote test test test3 AgentBridge live demo test - 19:21:08 AgentBridge live demo test - 19:22:40 test commit A - 19:29:41 test commit B - 19:30:52 test commit C - 19:32:19 test commit D - 20:10:24 test commit - 23:16:51 test commit - 01:13:38 test commit - 12:25:20
