@xenarch/agent-mcpMCP Server30/100 via “mcp protocol integration for claude, cursor, langchain, and crewai”
x402 MCP server for AI agent payments. Lets Claude, Cursor, LangChain and CrewAI pay for HTTP 402–gated APIs with USDC micropayments on Base L2. Non-custodial, 0% fee. Unlike Cloudflare Pay-Per-Crawl, works on any host and settles directly on-chain.
Unique: Implements MCP as the primary integration surface, allowing agents to access paid APIs through standard tool-calling semantics without SDK-specific code. Supports multiple agent frameworks (Claude, Cursor, LangChain, CrewAI) through a single MCP server, reducing integration surface area and enabling cross-framework agent composition.
vs others: More flexible than framework-specific SDKs because MCP is protocol-agnostic; agents can switch frameworks without rewriting payment logic. Simpler than building custom API wrappers for each agent framework.
