Code Index MCP

基于 SQLite 的代码仓库索引 MCP 服务器

概述

Code Index MCP 是一个 MCP(Model Context Protocol)服务器,用于对代码仓库建立索引并提供强大的搜索能力。它使用 SQLite 存储索引数据,支持全文搜索(FTS5)、符号搜索和结构分析。

核心功能

  • 代码索引: 自动扫描代码仓库,提取文件、符号(函数、类、方法)和代码内容
  • 全文搜索: 基于 SQLite FTS5 的高速全文搜索
  • 符号搜索: 按名称搜索函数、类、方法等符号
  • 可观测性: 内置日志系统,记录所有工具调用和性能指标

快速开始

安装

pip install code-index-mcp-zeng

使用 MCP 客户端

配置你的 MCP 客户端(如 Claude Code):

{
  "mcpServers": {
    "code-index": {
      "command": "python",
      "args": ["-m", "code_index_mcp"]
    }
  }
}

基本使用

from code_index_mcp import CodeIndexServer

server = CodeIndexServer()

MCP 工具

本服务提供 8 个 MCP 工具:

1. index_repository

索引整个代码仓库。

{
  "name": "index_repository",
  "arguments": {
    "repo_path": "/path/to/repo",
    "force_rebuild": false
  }
}

参数:

  • repo_path (必填): 代码仓库路径
  • force_rebuild (可选): 是否强制重建索引,默认 false

返回:

{
  "success": true,
  "stats": {
    "files_indexed": 150,
    "symbols": 1200,
    "content_blocks": 5000,
    "elapsed_seconds": 2.5
  }
}

2. find_files

按文件名或路径搜索文件。

{
  "name": "find_files",
  "arguments": {
    "query": "test",
    "extensions": [".py", ".js"],
    "limit": 20
  }
}

3. find_symbols

搜索代码符号(函数、类、方法等)。

{
  "name": "find_symbols",
  "arguments": {
    "query": "calculate",
    "kind": "function",
    "limit": 20
  }
}

4. find_content

在代码内容中进行全文搜索。

{
  "name": "find_content",
  "arguments": {
    "query": "def.*main",
    "regex": true,
    "file_pattern": "*.py",
    "limit": 20
  }
}

5. get_structure

获取单个文件的结构信息。

6. get_stats

获取索引统计信息。

7. get_logs

查询工具调用日志(可观测性)。

8. get_call_stats

获取工具调用统计信息。
