Energy is the universal key.

A bitcoin-orange softwar fortress glowing against an indigo storm sky. Anvil-shaped power-grid silhouette stands above stone parapets, candlelit blueprints unfurl on a desk below, copper conduits run along the walls. The word "ENERGY" is rendered at the bottom in clean white sans-serif.

MCP Suite for AI Agents

Building AI agents that call each other? Every one needs to know: who's calling, can I trust them, how much should I charge them? The MCP suite is identity-priced agent infrastructure on Lightning. Drop-in, no accounts, no KYC.

Identity-gated MCP auth. Price tool calls by Depth-of-Identity score. Lightning-paid via L402.
npm install @powforge/mcp-identity
@powforge/vote
Sybil-resistant voting weighted by DoI. Each vote weighed by the voter's accumulated proof-of-work.
npm install @powforge/vote
@powforge/news-witness
DoI-weighted news credibility scoring. NIP-33 vouching events for collaborative news verification.
npm install @powforge/news-witness
@powforge/comment-witness
DoI-weighted comment credibility for discussion threads. One long-tenured human outweighs 500 sock-puppet replies.
npm install @powforge/comment-witness
@powforge/forge-whisper-mcp

Why Proof-of-Work?

CAPTCHAs train AI models with your labor. Bot detection services track your users across the web. API keys create vendor lock-in. There is a better way: make every request cost a tiny amount of energy.

Proof-of-work is the oldest anti-spam technique in computing. Bitcoin proved it scales. PowForge brings it to your website, your API, your relay. Bots fail because energy is real. Humans pass because the cost is trivial.

You proved it when you entered this page.
