pmcp — Claude Code MCP server: features and setup
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.
Open on GitHubWhat pmcp 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.
What it helps with
- 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 for the agent
- 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

Questions about pmcp
How do I install the pmcp SQL server?
Run cargo install pmcp-sql-server, then start it with pmcp-sql-server --config <path>. You can also pass the SQL schema with --schema <path>.
What does pmcp do?
It provides a Rust SDK and tooling for building MCP servers. SQL and OpenAPI/HTTP servers can be configured, while Excel workbooks can be compiled into bundles for serving.
Do I need Rust to build a pmcp server?
The config-driven SQL and OpenAPI/HTTP servers do not require you to write Rust code. To extend a server as a project, scaffold a crate with cargo pmcp new.
