Cursor Acp

Use your Cursor subscription models (Claude Opus/Sonnet 5.5, Composer 2.5, GPT-5.6, Grok) inside Hermes Agent via the Cursor CLI's ACP server (`agent acp`). Install with one command (`npx hermes-cursor-acp`) or `hermes plugins install cursor-acp`. The plugin rewrites `.cursor/cli.json` in an empty private workspace every run with a deny-all list (`Read`, `Write`, `Shell`, `WebFetch`, `Mcp`) to prevent Cursor's native CLI tools from accessing host files. It includes a custom extractor that recovers both flat `{"name", "arguments"}` and inline `<tool_call>` blocks that standard regex bridges drop, retries on concurrent `set_model` calls, and reports `usage=None` so Hermes proactive context compression functions correctly.

Good to know before installing

Sends the full conversation, Hermes tool schemas and tool results to Cursor through your locally installed, signed-in Cursor CLI (`agent acp`); Cursor's own tools are fenced by a deny-all `.cursor/cli.json` that the plugin rewrites in a private workspace under `$HERMES_HOME/cache/cursor-acp-workspace` on every start (a differing existing file is backed up to `cli.json.bak`), and Hermes executes every tool call under its own approvals.

From the plugin's catalog listing.

How to install

  1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
    hermes plugins install cursor-acp
  2. Said no? Turn it on later:
    hermes plugins enable cursor-acp
  3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
