Summary

AI summary

Added stdio transport support for local MCP clients and exposed additional server APIs.

Full changelog

Added

  • Added stdio transport support: new prts-mcp-ts-stdio npm bin and
    ts/src/server-stdio.ts entry point. Reuses the existing
    createMcpServer factory and runStartupSync; connects an
    StdioServerTransport for single-session local MCP clients (Claude
    Desktop, Claude Code, Cursor). Breaks the 2.0 transport split — the
    TypeScript implementation now supports both Streamable HTTP (existing
    prts-mcp-ts / prts-mcp-ts-bun bins) and stdio.
  • Added start:stdio / start:stdio:bun npm scripts.
  • Added e2eStdio.test.ts covering stdio initialize handshake, tools/list,
    and graceful error handling.
  • Extended smoke-package-bun.mjs to assert the prts-mcp-ts-stdio bin
    shim is installed and non-empty after npm pack + bun add.

Changed

  • server.ts now exports createMcpServer, SERVER_VERSION, and log
    (previously module-private) so the stdio entry point can reuse them
    without duplicating tool registration logic.

Install

# Run directly with npx (Node.js entrypoint, zero extra runtime install)
npx prts-mcp-ts

# Or install globally
npm install -g [email protected]

# Bun runtime (default production runtime since 2.2.0)
bunx --bun -p [email protected] prts-mcp-ts-bun

The default Docker image (prts-mcp-ts:latest) runs under Bun since 2.2.0;
ts/Dockerfile.node provides the legacy Node.js image.
