True402 swap guard
Blocks token buys when true402 finds a honeypot or a rug in progress — one pre_tool_call hook in front of every trading tool, MCP server and terminal command (Base, Ethereum, BSC, Solana). Free edition: it never pays, holds no wallet key and has no payment code.
Good to know before installing
The pre_tool_call hook reads the command string of every tool call and the parameters of trading-named tools; when a call looks like a buy, each candidate token address and its chain (every 0x address in a trading shell command except well-known majors and an unambiguous sold token, which can include a recipient or wallet address) is sent to true402.dev's free check endpoint, with no prompts, amounts or other tool data. Uses true402's small daily free allowance; when it is used up, a token counts as unchecked and passes by default (configurable to ask or block). Blocks only on a definite danger verdict for a token being bought; a possible sale or a configured caution goes to the Hermes approval gate, and one "always" answer there silences all later guard prompts. No stored data, no shell commands, background processes or telemetry.

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install true402-swap-guard - Said no? Turn it on later:
hermes plugins enable true402-swap-guard - 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).
