A Rust toolkit for building MCP servers, including config-driven options that need no Rust code. Use it to expose SQL databases or REST APIs.

## What it does

pmcp brings together a Rust SDK for the Model Context Protocol and tools for building servers. SQL and OpenAPI/HTTP servers can be described in `config.toml` and run with a prebuilt binary; an Excel workbook can be compiled into a bundle and served. The ecosystem also includes the `cargo pmcp` CLI, agent tooling, and a reference book.

SQL examples cover SQLite, Postgres, MySQL, and Athena. OpenAPI/HTTP servers support six outgoing-auth models, and demo configurations for live APIs require any credentials specified by their instructions. For a project you want to extend, `cargo pmcp new` scaffolds a Rust crate. Deployment targets include AWS Lambda, Google Cloud Run, and Cloudflare.

This is a development toolkit, not a ready-made database connection. Choose a server package and prepare its configuration or workbook first.

## Requirements
- Needs: a prebuilt binary from the repository releases

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- create a config-driven MCP server for a SQL database
- connect a REST backend through OpenAPI
- expose Excel output tables as MCP tools
- scaffold a Rust server for deployment

## Example prompts
- Build an MCP server for this SQL database from a configuration.
- Set up a server for this REST API using its OpenAPI description.
- Show me which tools would come from `pricing.xlsx`.
