Developer bypasses SDK, builds MCP server directly

By PulseAugur Editorial · [1 sources] ·

A developer built a Model Context Protocol (MCP) server without using the official SDK, opting instead to implement the wire protocol directly. This approach was chosen because the SDK's provided transports, STDIO and StreamableHTTPServerTransport, did not align with the developer's chosen backend framework, Hono, which uses a different request/response object structure. By adhering to the published MCP specification, the developer successfully created a server exposing nine tools over JSON-RPC 2.0, suitable for MCP-compatible clients like Claude Desktop and Cursor.

    I built an MCP server without the @modelcontextprotocol/sdk — here's what I learned

    <p>I shipped a Model Context Protocol server last month. It's live on Anthropic's official registry as <code>io.github.cammac-creator/openswissdata</code>. It exposes nine tools over JSON-RPC 2.0 to any MCP-compatible client (Claude Desktop, Cursor, Cline, you name it).</p> <p>I …
