MCP Connector

MCP 连接器

Connect to any MCP (Model Context Protocol) server and interact with its tools, resources, and prompts.

连接至任意MCP（Model Context Protocol）服务器，与其工具、资源和提示词进行交互。

Supported Transports

支持的传输方式

stdio — Launch a local MCP server as a subprocess (e.g.
```
npx @modelcontextprotocol/server-filesystem /path
```
)
sse — Connect to a remote MCP server via HTTP Server-Sent Events
streamable-http — Connect via the newer streamable HTTP transport (POST with SSE response)

stdio — 将本地MCP服务器作为子进程启动（例如
```
npx @modelcontextprotocol/server-filesystem /path
```
）
sse — 通过HTTP Server-Sent Events连接远程MCP服务器
streamable-http — 通过较新的流式HTTP传输方式连接（带SSE响应的POST请求）

Usage Flow

使用流程

Browse available servers with
```
mcp_browse
```
(or filter by category)
Connect by name from the registry:
```
mcp_connect(name="coingecko")
```
Discover available tools/resources with
```
mcp_list_tools
```
or
```
mcp_list_resources
```
Use them via
```
mcp_call_tool
```
or
```
mcp_read_resource
```
Disconnect when done with
```
mcp_disconnect
```

使用
```
mcp_browse
```
浏览可用服务器（或按类别筛选）
通过注册表中的名称连接：
```
mcp_connect(name="coingecko")
```
使用
```
mcp_list_tools
```
或
```
mcp_list_resources
```
发现可用的工具/资源
通过
```
mcp_call_tool
```
或
```
mcp_read_resource
```
使用它们
使用完毕后通过
```
mcp_disconnect
```
断开连接

Pre-configured Registry

预配置注册表

A curated list of MCP servers is maintained in

config/mcp_servers.yaml

. Connect to any of them by name — no URL or transport details needed:

mcp_connect(name="coingecko")     # Crypto market data
mcp_connect(name="exa")           # Neural web search
mcp_connect(name="dexpaprika")    # DEX data across chains

Use

mcp_browse()

to see all available servers, or filter by category:

mcp_browse(category="blockchain")
mcp_browse(category="developer")

Some servers require environment variables (API keys). The tool will tell you which ones are missing.

我们在

config/mcp_servers.yaml

中维护了一份精选的MCP服务器列表。只需通过名称即可连接其中任意服务器——无需提供URL或传输细节：

mcp_connect(name="coingecko")     # 加密货币市场数据
mcp_connect(name="exa")           # 神经网络网页搜索
mcp_connect(name="dexpaprika")    # 跨链DEX数据

使用

mcp_browse()

查看所有可用服务器，或按类别筛选：

mcp_browse(category="blockchain")
mcp_browse(category="developer")

部分服务器需要环境变量（API密钥）。工具会提示您缺少哪些变量。

Ad-hoc Connections

临时连接

You can still connect to any MCP server not in the registry by providing transport details:

您仍可通过提供传输细节，连接至注册表中未收录的任意MCP服务器：

stdio (local subprocess)

stdio（本地子进程）

mcp_connect(
    name="fs",
    transport="stdio",
    command="npx",
    args=["-y", "@modelcontextprotocol/server-filesystem", "/workspace"]
)

mcp_connect(
    name="fs",
    transport="stdio",
    command="npx",
    args=["-y", "@modelcontextprotocol/server-filesystem", "/workspace"]
)

SSE (HTTP Server-Sent Events)

SSE（HTTP Server-Sent Events）

mcp_connect(
    name="remote-tools",
    transport="sse",
    url="https://mcp.example.com/sse"
)

mcp_connect(
    name="remote-tools",
    transport="sse",
    url="https://mcp.example.com/sse"
)

Streamable HTTP

mcp_connect(
    name="api-server",
    transport="streamable-http",
    url="https://mcp.example.com/mcp"
)

mcp_connect(
    name="api-server",
    transport="streamable-http",
    url="https://mcp.example.com/mcp"
)

Using Connected Servers

使用已连接的服务器

Call a tool

调用工具

mcp_call_tool(
    server="coingecko",
    tool="get_price",
    arguments={"coin": "bitcoin"}
)

mcp_call_tool(
    server="coingecko",
    tool="get_price",
    arguments={"coin": "bitcoin"}
)

Read a resource

读取资源

mcp_read_resource(
    server="remote-tools",
    uri="file:///data/config.json"
)

mcp_read_resource(
    server="remote-tools",
    uri="file:///data/config.json"
)

Notes

注意事项

Connections persist for the duration of the session
Multiple servers can be connected simultaneously
Server names must be unique — reconnecting with the same name replaces the old connection
Environment variables can be passed to stdio servers via the
```
env
```
parameter
Registry entries are in
```
config/mcp_servers.yaml
```
— add new servers there (no code changes needed)

连接在会话期间保持有效
可同时连接多个服务器
服务器名称必须唯一——使用相同名称重新连接会替换旧连接
可通过
```
env
```
参数将环境变量传递给stdio服务器
注册表条目位于
```
config/mcp_servers.yaml
```
中——可在此添加新服务器（无需修改代码）
