01 · Install Llmtrim

before you install - you'll need

Set LLMTRIM_UPSTREAM_PROXY before connecting.

Claude Code

claude mcp add fkiene-llmtrim -- npx -y @llmtrim/cli

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "fkiene-llmtrim": {
      "command": "npx",
      "args": [
        "-y",
        "@llmtrim/cli"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MPL-2.0 - declared in the repository

npm package @llmtrim/cli - the @llmtrim scope differs from the repo owner (fkiene); confirm it's the project's official package

registry namespace io.github.fkiene is GitHub-verified and matches the repo owner
