Gemini CLI pdfedit mcp pdf_preview

How to: Gemini CLI pdfedit mcp pdf_preview

client:Gemini CLI transport:streamable-http tool:pdf_preview

Add pdfedit mcp to Gemini CLI

01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "pdfedit-mcp": {
      "httpUrl": "https://pdfedit-mcp-remote.niubai-pdfedit-remote-worker.workers.dev/mcp"
    }
  }
}

02
Save the file and restart Gemini CLI.
03
Ask for something pdf_preview does. Gemini CLI lists the server's tools on connect and calls pdf_preview itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that pdfedit mcp's identifier in your config matches the one above exactly.

Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs

Set these first

pdfedit mcp will not start until these are set, so pdf_preview never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 16 October 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.
