PMCP - Pragmatic Model Context Protocol

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)
• 🦀 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

# Seed a tiny demo DB, then serve it from config alone — two curated tools
# (list_books, books_by_author) + Code Mode for the long tail.
sqlite3 /tmp/pmcp-sqlite-explorer.db < crates/pmcp-sql-server/examples/sqlite-explorer.sql
pmcp-sql-server \
  --config crates/pmcp-sql-server/examples/sqlite-explorer.toml \
  --schema crates/pmcp-sql-server/examples/sqlite-explorer.sql

OpenAPI / HTTP — any REST backend, with six outgoing-auth models including OAuth passthrough (the server holds no standing credential and forwards the caller's own token, so it can only act as the signed-in user):

cargo install pmcp-openapi-server

# Curated configs ship with the crate — e.g. a London Tube (api_key) showcase and
# a Microsoft-Graph / Excel "Contoso" (oauth_passthrough) example. These talk to a
# live backend, so supply any required credential per the example's comments.
pmcp-openapi-server --config crates/pmcp-openapi-server/examples/london-tube.toml

Excel workbook — a governed spreadsheet, served as one MCP tool per output table (no config.toml, no schema; the single input is a compiled bundle@version directory). Author inputs and outputs as named Excel Tables and each output table becomes its own well-named, well-typed MCP tool with a DAG-derived input schema:

cargo install pmcp-workbook-server

# Preview the exact tool surface an AI will see — BEFORE you compile or deploy:
cargo pmcp workbook explain pricing.xlsx          # e.g. calculate_tax, estimate_refund

# Compile a governed workbook to a deterministic bundle (ingest → lint → compile →
# reconcile → fail-closed gate → write), then serve one calculation tool per output
# table — plus explain / get_manifest / diff_version / render_workbook — from the bundle alone.
cargo pmcp workbook compile pricing.xlsx --workflow quote --approver alice
pmcp-workbook-server --bundle-dir bundles/quote@1.0.0

Want to extend and deploy it? cargo pmcp new my-server --kind sql-server (or --kind openapi-server / --kind workbook-server) scaffolds the same config-driven server as a small crate, ready for cargo pmcp deploy to AWS Lambda / Google Cloud Run / Cloudflare / pmcp.run.

🚀 Path 2: AI-Assisted (Recommended for Rapid Prototyping)

Build production-ready MCP servers with AI assistance in minutes:

Prerequisites:

# Install Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup update

# Install cargo-pmcp
cargo install cargo-pmcp

Install Claude Code AI Agent:

Build your server:

You: "Create a weather forecast MCP server with tools for getting current conditions and 5-day forecasts"

Claude Code: [Invokes mcp-developer subagent]

I'll create a production-ready weather MCP server using cargo-pmcp.

$ cargo pmcp new weather-mcp-workspace
$ cd weather-mcp-workspace

🦀 Path 4: pmcp SDK Directly (For Fine-Grained Control)

Use the pmcp crate directly for maximum control:

Installation:

[dependencies]
pmcp = "2.0"
tokio = { version = "1", features = ["full"] }
serde = { version = "1", features = ["derive"] }
schemars = "0.8"  # For type-safe tools

Type-safe server example:

use pmcp::{ServerBuilder, TypedTool, RequestHandlerExtra, Error};
use schemars::JsonSchema;
use serde::{Deserialize, Serialize};

#[derive(Debug, Deserialize, Serialize, JsonSchema)]
#[schemars(deny_unknown_fields)]
struct WeatherArgs {
    #[schemars(description = "City name")]
    city: String,

    #[schemars(description = "Number of days (1-5)")]
    days: Option<u8>,
}

#[derive(Debug, Serialize, JsonSchema)]
struct WeatherOutput {
    temperature: f64,
    conditions: String,
}

async fn get_weather(args: WeatherArgs, _extra: RequestHandlerExtra) -> pmcp::Result<WeatherOutput> {
    // Validate
    if args.city.is_empty() {
        return Err(Error::validation("City cannot be empty"));
    }

    let days = args.days.unwrap_or(1);
    if !(1..=5).contains(&days) {
        return Err(Error::validation("Days must be 1-5"));
    }

    // Call weather API...
    Ok(WeatherOutput {
        temperature: 72.0,
        conditions: "Sunny".to_string(),
    })
}

#[tokio::main]
async fn main() -> pmcp::Result<()> {
    let server = ServerBuilder::new()
        .name("weather-server")
        .version("1.0.0")
        .tool("get-weather", TypedTool::new("get-weather", |args, extra| {
            Box::pin(get_weather(args, extra))
        }).with_description("Get weather forecast for a city"))
        .build()?;

    server.run_stdio().await?;
    Ok(())
}

🧩 Config-Driven Servers (No Rust)

Build production MCP servers over SQL and HTTP backends from a config.toml alone — the toolkit synthesizes curated tools + a Code Mode long tail, so exposing organizational data over MCP no longer needs a Rust programmer.

Crate	What it is
pmcp-server-toolkit	The backend-agnostic library: config types, the [[tools]] synthesizer, Code Mode wiring, and the connector/auth seams that the binaries below build on.
pmcp-sql-server	Shape-A binary serving a SQL database (SQLite / Postgres / MySQL / Athena) from config.toml + a schema file. Ships a runnable sqlite-explorer example.
pmcp-openapi-server	Shape-A binary serving any OpenAPI / HTTP backend, with six outgoing-auth models (incl. OAuth passthrough). Ships london-tube (api_key) and contoso-m365 (oauth_passthrough, Microsoft Graph + Excel) examples.
pmcp-workbook-server	Shape-A binary serving a governed Excel workbook as one named MCP tool per output table (e.g. calculate_tax, estimate_refund) plus infrastructure tools (explain / get_manifest / diff_version / render_workbook) from a compiled bundle@version directory alone — no config.toml, no schema. The Excel reader and JS code-mode are compile-time only and absent from the served binary (purity gate).
pmcp-toolkit-postgres / -mysql / -athena	Per-backend SQL connectors for the toolkit.

These binaries have cargo pmcp new --kind {sql-server,openapi-server,workbook-server} scaffold siblings that generate the same config-driven server as a small, deployable crate. See Path 1 above and the Config-Driven SQL Servers / OpenAPI / Config-Driven Workbook Servers chapters in the pmcp-book.
