VS Code Synapse Lounge extend_hit

How to: VS Code Synapse Lounge extend_hit

client:VS Code transport:streamable-http tool:extend_hit

Add Synapse Lounge to VS Code

  1. 01

    Open .vscode/mcp.json and merge this in. Keep any servers already there.

{
  "servers": {
    "synapse-lounge": {
      "type": "http",
      "url": "https://synapse-lounge.synapse-lounge.workers.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart VS Code.

  2. 03

    Ask for something extend_hit does. VS Code lists the server's tools on connect and calls extend_hit itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Synapse Lounge's identifier in your config matches the one above exactly.

Requires agent mode. MCP: Open User Configuration puts the same block in every workspace. VS Code docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
