How to add Substack to VS Code & GitHub Copilot

Open the Command Palette and run MCP: Add Server. Choose HTTP for a server URL or Command (stdio) for a local install command.
Or edit .vscode/mcp.json in your workspace: VS Code’s format puts servers under a top-level "servers" object (remote: "type": "http" + "url"; local: "type": "stdio" + "command"). Portable Copilot files (.mcp.json, ~/.copilot/mcp-config.json) use "mcpServers" instead, so don’t copy between them unchecked.
Sign in if the server asks, then use its tools in Copilot agent chat.

Example for Substack by Cotlet (from the table above), in .vscode/mcp.json:

{
  "servers": {
    "substack": {
      "type": "http",
      "url": "https://cotlet.dev/mcp/v1/substack/connect"
    }
  }
}

Menus change, so check the VS Code MCP configuration reference. Every server page has a copy-paste config for VS Code & GitHub Copilot.

Is it safe to connect Substack to VS Code & GitHub Copilot?

Check the publisher and trust grade first. Substack doesn't run an official MCP server we can verify, so every server here comes from a third party and can see whatever your account can.
