Model Context Protocol
Connect Proxygate as an MCP server
Give your AI agent one identity and one prepaid USDC balance to discover and call any API in the marketplace. The agent searches the catalog, calls an endpoint, and pays per request in USDC on Solana. Provider keys never leave the gateway.
Connect in one step

It is a Model Context Protocol server that gives an AI agent one identity and one prepaid USDC balance to discover and call any API in the Proxygate marketplace. The agent searches the catalog, calls an endpoint, and pays per request in USDC on Solana, all from inside its MCP client.
Each call_api request spends from the agent’s prepaid USDC balance and returns a signed receipt with the exact amount charged. There is no subscription and no upstream API key to manage: Proxygate injects the provider key server-side per request.
Any MCP-compatible client over Streamable HTTP, including Claude, Claude Code, and Cursor. Point the client at https://gateway.proxygate.ai/mcp and authenticate to start spending from your balance.
No. Keys live in the gateway and are injected per request. Agents authenticate to Proxygate only; they never see or handle the upstream provider credentials.
Ways to connect your agent
Four integration paths reach the same marketplace, one prepaid USDC balance, and the same provider keys kept server-side. Pick the one that fits how your agent runs.
