Turn any MCP server into a portable Agent Plugin (mcp.json + workflow skill) built from evidence: the server's self-description, your past sessions with it, its docs and a read-only probe. Validates and installs the package in linked mode, and checks a built plugin for server drift and new errors in use.

## Good to know before installing

Starts the target MCP server to introspect it; reads this profile's state.db read-only; logs redacted mcp__* call summaries locally (log_calls: false turns it off); inline server launches, writes outside its data dir and installs ask for approval.

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.

```bash
hermes plugins install mcp-plugin-creator
```

2. Said no? Turn it on later:

```bash
hermes plugins enable mcp-plugin-creator
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
