Orcpin

Overview

Orcpin is a Model Context Protocol (MCP) server: Paid x402 facts for AI agents: on-chain snapshots, endpoint reliability, trade math, free directory. In practice that means any MCP-compatible AI assistant can call Orcpin's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package orcpin-mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need ORCPIN_PRIVATE_KEY. The current release is v0.4.0.

Orcpin 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.
