How to: Zed Rendex: Rendering API for Images, PDFs & Content Extraction watch_update

client:Zed transport:streamable-http tool:watch_update

Add Rendex: Rendering API for Images, PDFs & Content Extraction to Zed

  1. 01

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

{
  "context_servers": {
    "rendex-mcp": {
      "url": "https://mcp.rendex.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Rendex: Rendering API for Images, PDFs & Content Extraction's identifier in your config matches the one above exactly.

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

Set these first

Rendex: Rendering API for Images, PDFs & Content Extraction will not start until these are set, so watch_update never becomes available.

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.
