Changelog

0.3.1.0

Added

• Simple unauthenticated HTTP transport (SimpleHTTPAPI / simpleHttpApp) in MCP.Server.HTTP, for local development or use behind a reverse proxy.
• MCP.Server.HTTP.Internal: shared handler core factored out of the HTTP transport, eliminating duplication between the JWT and simple transports.
• --simple-http flag in the example server.
• Integration tests for the simple HTTP transport.

0.3.0.1

Added

• Protocol types extracted into mcp-types; server remains as mcp.
• MCP.Server.Common: transport-agnostic types, state, request routing, and tool helpers.
• MCP.Server.HTTP: Servant-based HTTP transport with JWT authentication and SSE responses.
• MCP.Server.Stdio: stdio transport reading/writing JSON-RPC messages line-by-line.
• MCP.Server: re-exports all three submodules for backwards compatibility.
• Re-exports MCP.Protocol and MCP.Types from mcp-types for convenience.
• Integration test suite covering both HTTP and stdio transports.

Migration

• Change import MCP to import MCP.Server.
• If you only need types, depend on mcp-types instead of mcp.
