Zed B4 Index b4_compare

How to: Zed B4 Index b4_compare

client:Zed transport:streamable-http tool:b4_compare

Add B4 Index to Zed

  1. 01

    Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.

{
  "context_servers": {
    "b4-index": {
      "url": "https://b4-index.vercel.app/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

    Ask for something b4_compare does. Zed lists the server's tools on connect and calls b4_compare itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that B4 Index's identifier in your config matches the one above exactly.

Merge this into your existing settings object — do not replace the file. Zed 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.
