Gemini CLI PostAgent Resource/formats

How to: Gemini CLI PostAgent formats

client:Gemini CLI transport:streamable-http resource:formats

Add PostAgent to Gemini CLI

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

{
  "mcpServers": {
    "postagent": {
      "httpUrl": "https://api.postagent.sh/mcp"
    }
  }
}

02
Save the file and restart Gemini CLI.
03
formats is surfaced wherever your client lets you attach context. It is context to attach, not an action to run.
04
If it does not appear, check that PostAgent is connected and that you are looking at its resources rather than its tools.

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

Same resource, other clients

Read from the server itself, by connecting to it and calling resources/list on 24 September 2026. A listing does not declare its resources, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each resource's type and contents.
