Setup snapshot

git clone https://github.com/Undermybelt/skill-cerberus-mcp.git
  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Cerberus MCP Skill

AST-based code exploration with 90%+ token reduction

功能

Cerberus MCP 是一个模型上下文协议（MCP）服务器，通过抽象语法树（AST）分析提供高效的代码探索能力，可将 token 使用量减少 90% 以上。它实时生成调用图、依赖分析和代码结构概览，让 AI 代理能以极低成本理解大型代码库。

核心特性

  • ✅ 90%+ Token 减少 - AST 压缩大幅降低 LLM 上下文负担
  • ✅ 调用图生成 - 自动构建函数调用关系图
  • ✅ 实时代码探索 - 毫秒级响应，支持超大型仓库
  • ✅ MCP 原生 - 标准 Model Context Protocol，与所有 MCP 客户端兼容
  • ✅ 多语言支持 - 支持 Python、TypeScript/JavaScript、Go、Rust
  • ✅ 增量更新 - 仅分析变更部分，性能更优

使用场景

  • 代码审查助手 - 快速理解 PR 影响范围
  • 架构分析 - 生成系统依赖图谱
  • 调试辅助 - 追踪复杂调用链
  • 文档生成 - 基于 AST 自动生成 API 文档
  • 迁移规划 - 评估重构影响范围

命令

# 启动 Cerberus MCP 服务器
/cerberus-mcp start --repo /path/to/codebase --language python

# 查询调用图
/cerberus-mcp callgraph --function "main" --depth 3

# 查找依赖
/cerberus-mcp deps --module "utils" --include-transitive

# 分析影响
/cerberus-mcp impact --files changed.ts --max-hops 5

# 性能统计
/cerberus-mcp stats --format json

配置

cerberus-mcp.yaml:

mcp:
  server:
    port: 8080
    transport: stdio  # stdio|sse

analysis:
  languages:
    - python
    - typescript
    - go
    - rust
  max_files: 10000
  cache:
    enabled: true
    ttl: 1h
    path: ~/.cache/cerberus

reduction:
  ast_compression: true
  deduplicate_imports: true
  inline_small_functions: true
  threshold_lines: 3

output:
  format: mcp  # mcp|json|dot
  include_comments: false
  max_depth: 10

性能指标

| 指标 | 数值 | |------|------| | Token 减少率 | 90-95% | | 1000 文件分析时间 | <2s | | 内存占用 | ~100MB | | 调用图生成 | <100ms | | 首次启动 | <10s |

Integration

与 smartcat-mcp 配合使用可实现跨仓库代码导航：

# Cerberus 负责本地 AST 分析
cerberus-mcp start --repo . --language typescript

# Smartcat 提供云端语义搜索
smartcat-mcp start --api-key YOUR_KEY

技术栈

  • Model Context Protocol (MCP)
  • Tree-sitter (多语言 AST 解析)
  • Node.js (MCP 服务器)
  • LRU Cache (增量分析)
  • Graphviz (可选可视化)

    }
  }
}

安全

  • 仅读取，不修改源代码
  • 缓存数据本地存储（可选加密）
  • 无网络外连（除非配置远程仓库）
