BlockRunAI/blockrun-mcp

Live data for AI agents — search, research, markets, crypto, X/Twitter. Pay-per-call via x402 micropayments.

What it solves

BlockRun MCP removes the friction of integrating multiple data and action providers for AI agents. Instead of requiring agents to manage separate accounts, API keys, and credit card subscriptions for every vendor, it provides a single, self-custody wallet interface. This allows agents to access a wide array of tools—ranging from real-time market data to media generation—using a pay-per-call model settled in USDC.

How it works

It is an open-source server implementing the Model Context Protocol (MCP), which integrates with clients like Claude Desktop or Cursor. It uses a self-custody wallet (on Base or Solana) as the primary method for authentication and payment via the x402 protocol.

When an agent needs a tool, it makes a request through the MCP server; the server then routes the request to the provider and charges a small fee in USDC from the user's wallet. For high-stakes actions like trading on Polymarket, the system uses a non-custodial architecture where the agent signs transactions locally, ensuring the user maintains control of their funds.

Who it’s for

  • AI Agent Developers: Those building agents that need real-time web, on-chain, and financial data without managing complex API infrastructures.
  • Power Users of MCP Clients: Users of Claude Code, Cursor, or Windsurf who want to extend their AI's capabilities with live data and trading tools.
  • Agentic Workflows: Developers creating autonomous agents that require a budget-controlled, pay-as-you-go payment system.
