Editor Relayv2.0.0 · VS Code 1.101+

Your agent asks.
VS Code answers.

Editor Relay is a VS Code extension that runs a small MCP server on your machine. Any AI agent can use it to read what you're working on, and to use the language servers, terminal, git and debugger you already have.

Nothing leaves your machine. The relay only listens on localhost.

§1 Setup

  1. Install the extension. The server starts with VS Code, and the status bar reads Editor Relay: Running.

    code --install-extension SahilTiwaskar.vscode-context-bridge

  2. Connect your agent. Copilot finds it on its own. Other clients need the URL and your token:

    claude mcp add --transport http editor-relay \
  http://127.0.0.1:3210/mcp --header \
  "Authorization: Bearer $(cat ~/.vscode-context-bridge/token)"

  3. Ask normally: who calls this function? rename it everywhere. why did my last command fail? The agent picks the tools.

§3 Safeguards

Edits wait for you. Proposals, quick fixes and renames open as a diff with Accept and Reject. Nothing is written until you accept.

Commands wait for you. Terminal commands ask first, then run in a terminal you can see.

It stays local. The relay listens on 127.0.0.1 only and every request needs your token. Files like .env can be hidden from it entirely.

§4 In practice

› fix the error I'm looking at

get_context          main.ts, line 4 selected
get_diagnostics      Cannot find name 'multiply'
go_to_definition     src/math.ts:5
get_code_actions     Add import from "./math"
apply_code_action    waiting for review … accepted
run_task test        exit 0

Added the missing import. Tests pass.
