Architecture

• src/index.ts is the root public barrel and package entrypoint.
• src/mcp/ contains MCP handlers, tools, prompts, and resources.
• src/provider-mcp.ts is part of the package's public or composition surface.

Notes

• MCP protocol compliance is critical; transport layer must stay spec-compliant.
• Do not introduce runtime-specific (Node/browser) dependencies in the transport layer.
