Pmcp MCP server

PMCP - Pragmatic Model Context Protocol

<!-- QUALITY BADGES START --> <!-- QUALITY BADGES END -->

Production-grade Rust implementation of the Model Context Protocol (MCP) - 16x faster than TypeScript, built with Toyota Way quality principles

Overview

PMCP is a complete MCP ecosystem for Rust, providing everything you need to build, test, and deploy production-grade MCP servers — in Rust, or from configuration alone:

• 🧩 Config-Driven Servers - Build SQL & OpenAPI/HTTP MCP servers from a config.toml, or serve a governed Excel workbook from a compiled bundle — all no Rust required (pmcp-server-toolkit, pmcp-sql-server, pmcp-openapi-server, pmcp-workbook-server)
• 🤝 Agents & Teams - Build deploy-anywhere agents and small teams: the agent loop (pmcp-agent), four reference team servers (pmcp-team-servers), and a portable AI-Package format (pmcp-package) — driven from the cargo pmcp agent/team/package verbs
• 🦀 pmcp SDK - High-performance Rust crate with full MCP protocol support
• ⚡ cargo-pmcp - CLI toolkit for scaffolding, testing, and development
• 📚 pmcp-book - Comprehensive reference guide with 27 chapters
• 🎓 pmcp-course - Hands-on course with quizzes and exercises
• 🤖 AI Agents - Kiro and Claude Code configurations for AI-assisted development

Why PMCP?

• Performance: 16x faster than TypeScript SDK, 50x lower memory
• Safety: Rust's type system + zero unwrap() in production code
• Quality: Toyota Way principles - zero technical debt tolerance
• Complete: SDK, tooling, documentation, and AI assistance in one ecosystem

Quick Start

Choose your path based on experience and preference:

🧩 Path 1: Config-Only Servers — No Rust Required (SQL & OpenAPI)

New in v2.9 — this removes the biggest blocker to putting organizational data behind MCP: you no longer need a Rust programmer. Describe a production MCP server over a SQL database or any OpenAPI / HTTP backend in a config.toml — declare the backend, a handful of curated tools, and a Code Mode policy — and a prebuilt binary serves it. No Rust, no recompiling. Curated tools cover the common ~20%; Code Mode handles the long-tail ~80% by generating queries against your schema/spec under a static, default-deny policy. A business analyst curates the API slice in config; the toolkit does the rest.

SQL — SQLite / Postgres / MySQL / Athena (runnable from a checkout of this repo):

cargo install pmcp-sql-server
