Behavry Integration — VS Code + GitHub Copilot

VS Code 1.99+ supports MCP servers for use with GitHub Copilot Chat. The configuration file uses the key servers (not mcpServers like other clients).

Requires: VS Code 1.99 or later + GitHub Copilot extension.

Prerequisites​

Config File Locations​

OSPath
macOS~/Library/Application Support/Code/User/mcp.json
Windows%APPDATA%\Code\User\mcp.json
Linux~/.config/Code/User/mcp.json

Quick Setup​

make setup

This detects VS Code, provisions a vscode-local agent, and merges into the VS Code MCP config — all in one step.

After setup, reload the VS Code window: Command Palette → Developer: Reload Window

To connect only VS Code:

cd backend && poetry run python ../demos/setup/create_dev_agent.py --client vscode

Note: VS Code uses "servers" (not "mcpServers") as the top-level key in mcp.json.

Verify​

  1. Open Copilot Chat (Ctrl+Alt+I)
  2. Click the tools icon — Behavry servers should appear
  3. Ask: "Using the filesystem tool, list files in /workspace"
  4. Check http://localhost:5173 → Live Activity

Token Refresh​

Tokens expire in ~8 hours. Refresh all enrolled editors at once:

make tokens

Then reload the VS Code window (Developer: Reload Window).

Troubleshooting​

MCP servers not visible in Copilot Chat

  1. Confirm VS Code version is 1.99+: Help > About
  2. Confirm the Copilot Chat extension is installed and you are signed in
  3. Reload the window after applying the config

"servers" key vs "mcpServers"

VS Code uses "servers" (not "mcpServers"). If you copy config from another client, update the key name.

Backend not reachable

Run curl http://localhost:8000/health to confirm the Behavry stack is up.
