mcp-probe-go

A Go-based Model Context Protocol (MCP) server for searching and extracting code using ElasticSearch and AST-grep, with support for code block extraction and advanced code queries.

Features

• Search code in your repository using ElasticSearch queries.
• Query code using ast-grep structural pattern matching.
• Extract code blocks from files by line number or symbol name.
• Supports filtering, context lines, test code inclusion, and output formatting.

Getting Started

Prerequisites

• Go 1.23+ installed
• probe-go-sdk and mcp-go dependencies

Build

cd cli
go build -o probe-mcp-server main.go

Run

./probe-mcp-server

The server will start and listen for stdio requests.

Usage

The server registers the following tools:

• search_code: Search code using ElasticSearch queries.
• query_code: Search code using ast-grep patterns.
• extract_code: Extract code blocks by line or symbol.

Each tool exposes a set of arguments for flexible code search and extraction. See the code for details on each tool's options.

Development

• Main server logic is in main.go and cli/main.go.
• Tool handlers are in search_code.go, query_code.go, and extract_code.go.
• Uses the mcp-go server framework.
