概要

What is Sample MCP Server?

Sample MCP Server is a Model Context Protocol (MCP) server that connects to a PostgreSQL database. Built with Go and GORM, it provides CRUD operations and aggregation for financial accounts, categories, and transactions. It is intended as a reference implementation for MCP server development.

How to use Sample MCP Server?

Prerequisites: Go 1.24+, Mage, Docker, and Docker Compose. Clone the repository, then start the PostgreSQL database with mage docker:up and build with mage build. For development, run mage dev. Configuration is done via a config.yml file or the MCP_SERVER_CONFIG environment variable.

Key features of Sample MCP Server

  • Account management (create, read, update, delete)
  • Category management (create, read, update, delete)
  • Transaction tracking (create, read, update, delete)
  • Transaction aggregation (sum, count by account)
  • Configurable PostgreSQL connection (also supports MySQL and MSSQL)

Use cases of Sample MCP Server

  • Manage financial accounts with create, read, update, delete operations.
  • Organize transactions into categories for better tracking.
  • Record and retrieve financial transactions with amounts, dates, and descriptions.
  • Aggregate transaction data to compute sums and counts per account.

よくある質問

1

What runtime dependencies are required?

Go 1.24 or higher, the Mage build tool, Docker and Docker Compose, and a PostgreSQL instance (or the included Docker setup).

2

How do I configure the database connection?

Copy `config.yml.sample` to `config.yml` and edit the values. You can also point to a custom config file using the `MCP_SERVER_CONFIG` environment variable. Default settings are provided for host, port, user, password, and database name.

3

Which database systems are supported?

PostgreSQL is the default, but the configuration also supports MySQL and MSSQL via the `Type` field.

4

How can I run tests?

Unit tests: `mage test`. Integration tests: `mage integrationtest`, which automatically starts Docker services and waits for PostgreSQL.

5

What does the data model look like?

The model includes three entities: Account (ID, name, type), Category (ID, name, type), and Transaction (amount, date, description, with relationships to accounts and categories).
