Zed Lob MCP by usefulapi lob_create_letter

How to: Zed Lob MCP by usefulapi lob_create_letter

client:Zed transport:streamable-http tool:lob_create_letter

Add Lob MCP by usefulapi to Zed

  1. 01

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

{
  "context_servers": {
    "lob": {
      "url": "https://lob.usefulapi.io/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Lob MCP by usefulapi'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 14 November 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.
