This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.

We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

What is go-mcp-demo?

go-mcp-demo is an MCP Server and Client demo built on mark3labs/mcp-go that integrates with Ollama to enable local large language models to call tools via natural language. It targets developers who want to see how an MCP server communicates with an MCP client and performs tasks like reading SQL files and executing MySQL queries.

How to use go-mcp-demo?

Install Ollama and pull a model (e.g., qwen2:1.5b). Edit pkg/config/config.yml to set the Ollama model, MySQL connection, and a .sql file path. Then run cmd/server/main.go to start the main server (default port 2001), and separately run cmd/mcp-server/main.go to start the MCP server (default port 2002). The MCP server registers two tools: read_file and query_db.

Key features of go-mcp-demo

Integrates MCP Server and Client communication framework
Supports reading local .sql files via natural language
Supports executing arbitrary MySQL queries via natural language
Uses Ollama local LLM for inference (default port localhost:11434)

Use cases of go-mcp-demo

Demonstrate MCP communication with a local LLM and database tools
Allow users to query a MySQL database by simply describing what they want
Enable reading SQL file contents without manually opening files

Frequently asked questions

What runtime dependencies does go-mcp-demo require?

It requires Go (to run the code), Ollama (to serve a local LLM), and a MySQL database.

How is the LLM model configured?

Edit `config.yml` and set the `model` field to match the name used in `ollama pull` and `ollama run` (e.g., qwen2:1.5b).

Where does the SQL file path go?

In `config.yml` under `sql.sqlFilePath`, provide the absolute path to your `.sql` file.

What tools are registered by the MCP server?

Two tools: `read_file` (reads the specified .sql file) and `query_db` (executes arbitrary SQL and returns results).

What transport does go-mcp-demo use?

The servers listen on localhost TCP ports (2001 for the main client, 2002 for the MCP server). The README does not specify authentication.
