Mpp32 Mcp Server

mpp32/mpp32

Turns paid API calls into a single line of agent code. Instead of managing API keys, billing accounts, and payment handlers for every premium service, your agent browses a federated catalog of 4,500+ endpoints across token analytics, market data, image generation, and DeFi intelligence, then pays per call in USDC on Solana or Base. The x402 protocol handles settlement on chain in seconds while you never touch the money. Ships with a free Solana token intelligence tool that returns alpha scores, rug risk, whale flow, and pump probability. Useful when your agent needs real data that costs real money and you would rather write logic than payment plumbing.

Install

From registry metadata

$ npx add-mcp mpp32-mcp-server --name mpp32 --env 'MPP32_AGENT_KEY=${MPP32_AGENT_KEY}' --env 'MPP32_SOLANA_PRIVATE_KEY=${MPP32_SOLANA_PRIVATE_KEY}' --env 'MPP32_PRIVATE_KEY=${MPP32_PRIVATE_KEY}'

Run in your terminal. add-mcp asks which agents to add it to, then asks for each value it needs. Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Run in your terminal. Replace YOUR_* placeholders with real values; add --scope user to install for every project.
