🧠 MCP 聚合工具服务 / MCP Aggregated Tool Service

License Python FastAPI Dockerized

一个基于 FastAPI + fastapi_mcp 实现的多工具统一接入平台,支持模块化、自动注册与异步扩展。适用于将多个 AI 工具或微服务聚合为一个统一接口服务,支持标准化输入输出格式,便于前端集成或 LLM 系统调用。

A modular, extensible and FastAPI-based MCP (Multi-Component Platform) tool aggregation service. Easily connect and expose independent tools through standardized APIs. Perfect for frontend integration or large language model (LLM) orchestration.


🌟 功能特点 / Features

  • ✅ 支持多工具自动注册(基于目录扫描)

  • ✅ 所有接口统一 POST 方式 + BaseModel 校验

  • ✅ 支持异步 httpx 接口调用

  • ✅ 标准化 JSON 响应格式(success/error)

  • ✅ Docker 一键部署支持

  • ✅ 配套开发说明文档,便于扩展工具模块

🚀 快速开始 / Quick Start

🧰 依赖要求 / Requirements

  • Python 3.8+

  • pip

  • Docker / Docker Compose(可选)

📦 本地运行 / Local Dev

# 安装依赖
pip install -r requirements.txt

# 启动服务
python main.py

默认服务地址:http://localhost:8000/mcp

🐳 使用 Docker 部署 / Docker Deployment

# 构建 & 运行
docker-compose up --build -d

# 访问 MCP 工具服务
http://localhost:8000/mcp

🧱 工具模块开发规范 / Tool Module Guidelines

每个工具应放置于 tools/ 目录下(可多层嵌套),并包含:

  1. 使用 pydantic.BaseModel 定义参数;

  2. 使用 @__mcp_server__.tool() 注册工具函数;

  3. 返回 success_response()error_response()

  4. (可选)异步调用外部接口 + 缓存结果。

示例参考:

from pydantic import BaseModel
from main import __mcp_server__, success_response

class MyParams(BaseModel):
    name: str

@__mcp_server__.tool()
async def hello_tool(params: MyParams):
    return success_response({"message": f"Hello {params.name}!"})

🔗 接口说明 / API Usage

所有工具接口统一通过 /mcp 路径访问,自动根据模块注册。

请求方式:POST
请求格式:application/json
响应格式:

{
  "status": "success",
  "result": {
    ...
  }
}
