That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
📘 ApiBridge MCP
基于 Python 3.10+ 和 FastAPI 开发的HTTP API桥接MCP服务,支持多工具集(Toolkits)、动态工具加载、多种认证方式和自动API文档生成。
🚀 功能特性
多工具集支持: 从
toolkits/目录动态加载多个工具集(每个 JSON 文件一个工具集),每个工具集有独立的配置和工具。动态工具加载: 根据JSON配置文件自动创建和注册工具,无需修改代码。
灵活的认证机制: 支持
http basic和oauth2_jwt两种认证方式,可为每个工具集独立配置。中间件驱动的路由: 通过
ToolkitRoutingMiddleware中间件,根据Toolkit-CodeHTTP头动态路由到正确的工具集。内置工具: 提供
current_time,get_api_docs,api_version等实用内置工具。自动文档生成: 支持通过命令行生成所有或单个工具集的Markdown格式API文档。
异步HTTP客户端: 使用
aiohttp进行高效的异步外部API调用。容器化部署: 提供完整的Docker和Docker Compose配置,方便快速部署。

安装依赖
pip install -r requirements.txt配置工具集
在 toolkits/ 目录下创建JSON文件来定义你的工具集。例如, my_toolkit.json:
```json
{
"code": "my_toolkit",
"name": "My Custom Toolkit",
"description": "A toolkit for custom operations.",
"auth": {
"type": "http_basic",
"user_name": "myuser",
"password": "mypass"
},
"tools": [
{
"name": "my_tool",
"description": "Does something awesome.",
"path": "/custom/endpoint",
"method": "POST",
"parameters": { ... },
"response": { ... }
}
]
}
```配置环境变量 (可选)
创建
.env文件并根据.env.example的内容进行配置,可以覆盖settings.py中的默认值。
运行服务
python main.py服务默认启动在 http://0.0.0.0:8200。
🚀 使用方法
工具调用
所有工具调用都通过 /tools/ 端点进行。你需要提供 Toolkit-Code HTTP头来指定要使用的工具集。
请求示例:
POST /tools/ HTTP/1.1
Host: localhost:8200
Content-Type: application/json
Toolkit-Code: my_toolkit
{
"tool_name": "my_tool",
"parameters": { ... }
}内置工具
current_time: 获取当前时间。get_api_docs: 获取API文档。可使用toolkit_code参数获取特定工具集的文档。api_version: 获取服务版本。
📚 API文档生成
通过命令行生成Markdown格式的API文档。
生成所有工具集的文档:
python main.py --doc生成特定工具集的文档:
python main.py --doc --toolkit your_toolkit_code
文档将生成在 docs/ 目录下。
✅ 测试
项目包含一套完整的单元测试和集成测试。运行测试:
pytest🐳 Docker部署
使用提供的脚本构建和运行Docker容器。
构建镜像:
cd docker ./build_image.sh使用Docker Compose运行:
cd docker docker-compose up -d

📦 工具包列表(简版) / Toolkits List (Simple)
路由:GET
/debug/toolkits-simple返回:每个工具包的
toolkitCode、工具数量toolsCount和内置工具数量builtinCount
示例(PowerShell):
Invoke-RestMethod "http://127.0.0.1:8201/debug/toolkits-simple" | ConvertTo-Json -Depth 3English:
Endpoint: GET
/debug/toolkits-simpleReturns:
toolkitCode,toolsCount,builtinCountfor each toolkit
🔗 MCP Stream 调用约定 / MCP Stream Protocol
服务端内部注册名统一为:
toolkitCode__toolCode(避免跨工具包重名冲突,便于统计与治理)mcp:list-tools响应返回组合名toolkitCode__toolCode列表(与内部注册保持一致,避免客户端拿到纯名后底层出现 Unknown tool)mcp:call-tool支持两种调用方式:组合名:传
tool_name=toolkitCode__toolCode(推荐;同时提供Toolkit-Code以校验工具集存在与权限)纯名:传
tool_name=toolCode(兼容;中间件会根据Toolkit-Code自动改写为组合名)
Header 要求:
Accept必须包含application/json, text/event-stream,Content-Type使用application/json会话要求:若返回 “Missing session ID”,请先进行一次会话初始化(例如通过浏览器打开
/dashboard或按你的会话流程),再调用mcp:call-tool
示例(PowerShell):
# 初始化(内置方法)
Invoke-WebRequest -Uri "http://127.0.0.1:8200/mcp/stream" -Method POST -Headers @{ "x-client-key"="abc123"; "toolkit-code"="sale-solution-tools"; "Accept"="application/json, text/event-stream" } -ContentType "application/json" -Body '{"jsonrpc":"2.0","id":"init-1","method":"initialize","params":{"clientName":"CherryStudio","clientVersion":"1.0"}}'
# 列表工具(内置方法)
Invoke-WebRequest -Uri "http://127.0.0.1:8200/mcp/stream?toolkit-code=sale-solution-tools" -Method POST -Headers @{ "x-client-key"="abc123"; "Accept"="application/json, text/event-stream" } -ContentType "application/json" -Body '{"jsonrpc":"2.0","id":"list-1","method":"mcp:list-tools","params":{}}'
# 调用具体工具(纯 toolCode + Toolkit-Code)
Invoke-WebRequest -Uri "http://127.0.0.1:8200/mcp/stream" -Method POST -Headers @{ "x-client-key"="abc123"; "toolkit-code"="sale-solution-tools"; "Accept"="application/json, text/event-stream" } -ContentType "application/json" -Body '{"jsonrpc":"2.0","id":"call-1","method":"mcp:call-tool","params":{"tool_name":"current_time","arguments":{}}}'English:
Server internal registration uses
toolkitCode__toolCodeto avoid cross-toolkit naming conflicts and keep stats consistent.mcp:list-toolsreturns combined namestoolkitCode__toolCode(consistent with server registration; avoids Unknown tool when calling).mcp:call-toolsupports both:Combined name: send
tool_name=toolkitCode__toolCode(recommended; still provideToolkit-Codefor toolkit validation)Pure name: send
tool_name=toolCode(compatible; middleware rewrites usingToolkit-Code)
Headers:
Acceptmust includeapplication/json, text/event-stream,Content-Typeshould beapplication/json.Session: If you receive “Missing session ID”, initialize a session first (e.g., open
/dashboardin browser or follow your session init flow), then callmcp:call-tool.
🔐 日志脱敏策略 / Log Sanitization Policy
为满足安全规范,服务会对以下 Header/字段进行脱敏输出:
authorization、x-client-key、x-api-key、x-token、token、password日志中的敏感值统一显示为
***
English:
For security, logs mask sensitive headers/fields:
authorization,x-client-key,x-api-key,x-token,token,password.Masked values appear as
***in logs.
❗ 错误码与常见排错 / Error Codes & Troubleshooting
说明 / Notes:以下错误示例为典型形态,实际返回格式可能因 FastAPI 的异常处理而有所差异(可能返回 { "detail": "..." });建议客户端同时兼容 detail 和自定义 error.message 两种字段。
常见场景 / Common Cases:
缺失 Toolkit-Code(工具调用)/ Missing Toolkit-Code (tool call)
条件:调用
mcp:call-tool时未在 Header 或 Query 提供Toolkit-Code/toolkit-code请求示例(PowerShell):
Invoke-WebRequest -Uri "http://127.0.0.1:8201/mcp/stream" -Method POST -Headers @{ "x-client-key"="abc123" } -ContentType "application/json" -Body '{"jsonrpc":"2.0","id":"call-1","method":"mcp:call-tool","params":{"tool_name":"current_time","arguments":{}}}'预期响应(400):
{
"error": {
"code": 400,
"message": "Toolkit-Code required for tool call (send header 'Toolkit-Code' or query 'toolkit-code')",
"hint": "Use pure toolCode plus Toolkit-Code. Example: header Toolkit-Code=sale-solution-tools"
}
}或(FastAPI 默认)
{ "detail": "Toolkit-Code is required when calling tools" }工具名建议 / Tool naming recommendation
推荐:使用组合名
toolkitCode__toolCode;纯名也兼容(中间件会根据Toolkit-Code自动改写)。请始终提供
Toolkit-Code(header 或 query),以便服务在鉴权与治理上进行工具集校验。
工具包不存在 / Toolkit JSON not found
条件:
Toolkit-Code指向不存在的工具包 JSON请求示例:
Invoke-WebRequest -Uri "http://127.0.0.1:8201/mcp/stream" -Method POST -Headers @{ "x-client-key"="abc123"; "toolkit-code"="unknown-toolkit" } -ContentType "application/json" -Body '{"jsonrpc":"2.0","id":"call-3","method":"mcp:call-tool","params":{"tool_name":"current_time","arguments":{}}}'预期响应(404):
{
"error": {
"code": 404,
"message": "Toolkit not found: unknown-toolkit",
"hint": "Check available toolkits via /debug/toolkits-simple or /debug/tools-simple"
}
}或(FastAPI 默认)
{ "detail": "Toolkit not found: unknown-toolkit" }工具不存在(在指定工具包下)/ Tool not found in toolkit
条件:
tool_name在该Toolkit-Code下未注册请求示例:
Invoke-WebRequest -Uri "http://127.0.0.1:8201/mcp/stream" -Method POST -Headers @{ "x-client-key"="abc123"; "toolkit-code"="sale-solution-tools" } -ContentType "application/json" -Body '{"jsonrpc":"2.0","id":"call-4","method":"mcp:call-tool","params":{"tool_name":"non_exist_tool","arguments":{}}}'预期响应(404):
{
"error": {
"code": 404,
"message": "Tool not found in toolkit",
"hint": "Use /debug/tools-simple?toolkit=sale-solution-tools to confirm available toolCode"
}
}或(FastAPI 默认)
{ "detail": "Tool not found in toolkit" }内置 JSON-RPC 方法(不需要 tool_name)/ Built-in methods (no tool_name required)
条件:
initialize、mcp:list-tools等方法无需tool_name,会直接透传到 FastMCP请求示例:
Invoke-WebRequest -Uri "http://127.0.0.1:8201/mcp/stream" -Method POST -Headers @{ "x-client-key"="abc123"; "toolkit-code"="sale-solution-tools" } -ContentType "application/json" -Body '{"jsonrpc":"2.0","id":"init-1","method":"initialize","params":{"clientName":"CherryStudio","clientVersion":"1.0"}}'
Invoke-WebRequest -Uri "http://127.0.0.1:8201/mcp/stream?toolkit-code=sale-solution-tools" -Method POST -Headers @{ "x-client-key"="abc123" } -ContentType "application/json" -Body '{"jsonrpc":"2.0","id":"list-1","method":"mcp:list-tools","params":{}}'网络错误 / Network Errors:
“无法连接到远程服务器”:检查服务是否运行、端口是否开放(8201)、本机防火墙策略、代理软件拦截;可使用
netstat -ano | findstr 8201验证监听状态。
English:
Notes: Response formats may vary ({"detail":"..."} vs. custom error.message). Clients should handle both.
Common cases:
Missing Toolkit-Code (tool call)
Condition: Calling
mcp:call-toolwithoutToolkit-Code(header or query)Expected 400:
{ "error": { "code": 400, "message": "Toolkit-Code required", "hint": "Send header Toolkit-Code or query toolkit-code" } }Tool naming recommendation
Preferred: use combined names
toolkitCode__toolCode; pure names are compatible (middleware rewrites usingToolkit-Code).Always provide
Toolkit-Code(header or query) so the service can validate toolkit in auth and governance.
Toolkit JSON not found
Condition:
Toolkit-Codepoints to a non-existent toolkitExpected 404:
{ "error": { "code": 404, "message": "Toolkit not found: unknown-toolkit" } }Tool not found in toolkit
Condition:
tool_namenot registered under the given toolkitExpected 404:
{ "error": { "code": 404, "message": "Tool not found in toolkit" } }Built-in JSON-RPC methods
initializeandmcp:list-toolsrequire notool_name; they are passed through to FastMCP.
Network errors:
"Cannot connect to remote server": ensure the service is running, port 8201 is open, firewall allows local connections, and no proxy blocks requests; use
netstat -ano | findstr 8201to verify the listening state.
