Non-custodial burner wallet for AI agents: make a wallet, check balance, send, swap.
Non-custodial burner wallet for AI agents: make a wallet, check balance, send, swap.
A security suite for AI agents — the seatbelt that catches the dangerous thing BEFORE it happens. Three guards, each callable on its own (and as MCP tools), pairing with any wallet or identity stack:
chain-signer on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Configuration is passed through the environment: ETHERSCAN_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by Kevthetech143; worth a glance at recent repository activity before you build anything load-bearing on it.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
