K402 is a Model Context Protocol (MCP) server: Agent-payable APIs on Kaspa: LLMs, chain data, covenants, zk proofs — pay per call, no API key. In practice that means any MCP-compatible AI assistant can call K402's tools directly — the model decides when to use them in a conversation or agent run.
You can run K402 two ways: connect to the hosted endpoint at https://x402-compute.68cxgfyr0.workers.dev/mcp with no local install, or run it on your own machine via the Python package k402-mcp (via uvx). The current release is v0.7.0.
K402 is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below. If you maintain K402 for Kali123411, claim this listing to verify ownership, earn the Verified badge, and keep the details current.
