VS Code (Copilot)

Overview

VS Code connects to MCP servers through GitHub Copilot’s agent mode. It supports remote Streamable HTTP servers directly.

Setup

StackOne’s MCP endpoint is a remote, Streamable HTTP server:

https://api.stackone.com/mcp

Get your MCP URL

In the StackOne dashboard, open a connector, click Use in Agent, select a linked account, and copy the generated token URL.

Add the server to VS Code

Create .mcp.json in your workspace (or run MCP: Add Server from the Command Palette):

{
  "servers": {
    "stackone": {
      "type": "http",
      "url": "https://api.stackone.com/mcp?token={session_token}"
    }
  }
}

Verify

Open Copilot Chat in Agent mode, click the tools icon to confirm StackOne’s tools are listed, then ask:

What StackOne tools are available?

For API-key auth instead of a token URL, see Authentication & Security. Confirm the latest format in VS Code’s MCP servers docs.

Handling large tool catalogs

If the connector exposes many actions, add the tool-mode=search_execute query parameter to the MCP URL in your config. The client then registers just two tools — search + execute — and the agent discovers actions at runtime, so the context footprint stays flat however large the catalog:

https://api.stackone.com/mcp?tool-mode=search_execute

For a token URL, append it as an extra parameter: https://api.stackone.com/mcp?token=<session_token>&tool-mode=search_execute. See Tool Discovery for how search works, its accuracy, and the other modes.

Optimize and secure

With your agent connected, use StackOne’s platform features to optimize performance and secure every call.

Search & Execute

Reduce context and save tokens.

Data Sync

Reduce latency and enable semantic search.

Defender

Block prompt injections before they reach your agent.
