VS Code - OnePerfectSlice

VS Code connects to the hosted OnePerfectSlice server through GitHub Copilot’s MCP support. Nothing to install beyond Copilot.

MCP servers are used by Copilot’s Agent mode in the Chat view. Make sure GitHub Copilot is installed and you’re signed in.

Connect

Add the server

Open the Command Palette (Cmd/Ctrl+Shift+P) and run MCP: Add Server. Choose HTTP and enter:

URL: https://mcp.oneperfectslice.ai/mcp
Name: ops

This writes an entry to your mcp.json (workspace .vscode/mcp.json or your user profile):

{
  "servers": {
    "ops": {
      "type": "http",
      "url": "https://mcp.oneperfectslice.ai/mcp"
    }
  }
}

Authenticate

Start the server when prompted (or run MCP: List Servers → ops → Start). VS Code opens a browser for OAuth — log in to OnePerfectSlice and select the team whose data this connection should access. Approve the authorization back in VS Code if asked.

Verify

Run MCP: List Servers and confirm ops is running with its tools available. In the Chat view, open the tools picker (Agent mode) and check that the ops tools appear.

Test it

In the Chat view (Agent mode), try:

Use ops to list available slices

You should see a list_slices tool call and get back your team’s slices.

Troubleshooting

Problem	Solution
`ops` not in tools picker	Run MCP: List Servers, start `ops`, and ensure you’re in Agent mode
Authorization didn’t complete	Restart `ops` from MCP: List Servers and finish login + team selection
Wrong team’s data	Remove `ops` from `mcp.json`, re-add it, and select a different team
Server won’t start	Confirm the URL and that `type` is `http` in `mcp.json`

Switching teams

Each connection is scoped to one team. To switch, remove and re-add the ops server, then select the new team during sign-in.
