Architecture
MCP Server Network
edwin cloud operates as a distributed network of MCP servers:
Central MCP Server: Routes requests to protocol-specific MCP servers
Protocol MCP Servers: Handle protocol-specific transaction construction, execution, and context understanding
edwin-client SDK: Integrated into the agent, providing secure communication with edwin cloud
edwin Protocol
The edwin Protocol enables secure communication between the client and server:
