MCP protocol adds remote server support with new auth methods

By PulseAugur Editorial · [1 sources] ·

The MCP protocol has been updated to support remote servers, which are hosted HTTP endpoints that clients can connect to over the network. This contrasts with local stdio servers, which clients spawn and manage directly. The remote server protocol involves three core calls: initialize, tools/list, and tools/call, with variations in authentication methods including Bearer tokens, OAuth 2.1, and a novel x402 payment challenge using USDC on the Base network. AI
