Synapse Network MCP Server for paid API calls

synapsenetworkai/synapse-network-mcp-server

A payment gateway that turns MCP tools into paid API calls. You get three operations: discover_services to browse available APIs, invoke_and_pay to call them with USDC micropayments, and get_receipt for audit trails. The hosted Remote MCP endpoint at mcp.synapse-network.ai/mcp works with ChatGPT custom apps and Claude connectors without local setup, or install the stdio version via npm. Authentication uses Synapse Agent Keys. This is infrastructure for agent-to-API payments, not a bionetworks platform. Reach for it when you want agents to discover and pay for third-party services at runtime rather than managing API keys and billing yourself.

Synapse Network MCP Server for paid API calls

License: MIT MCP

Synapse Network MCP Server for paid API calls is the official Model Context Protocol (MCP) server from SynapseNetworkAI. "Synapse Network MCP" with a space and "SynapseNetwork MCP" without a space refer to this same SynapseNetworkAI/Synapse-Network-MCP-Server project. It gives ChatGPT custom MCP apps, Claude connectors, Cursor, Claude Desktop, Devin, and MCP-compatible agent frameworks a stateless way to discover external APIs, invoke them, and retrieve receipts through SynapseNetwork agent payments.
