Summary

An open-source tool that enables AI agents to make Bitcoin Lightning payments with hard spending caps enforced server-side, preventing abuse even under prompt injection. Includes an MCP server for Claude Desktop/Cursor integration and Python/TypeScript SDKs.

I built an open-source way for an AI agent to make real payments (Bitcoin over Lightning) with spending limits enforced in code, not vibes. The agent gets a scoped API key and a virtual balance with a hard policy: per-transaction / daily caps, rate limit, destination allowlist. The limits are enforced server-side before anything moves — so even a jailbroken or prompt-injected agent can't spend more than you allowed, or pay anyone you didn't allowlist. The agent never holds a signing key. There's an MCP server, so Claude Desktop / Cursor can pay directly as a tool call, plus Python + TypeScript SDKs. Self-hosted, MIT-licensed, runs on your own node. pip install conduit-btc Curious what this community thinks about the trust model for agents touching money. Code:
