读取资源请求示例：

<use_mcp_tool> <server_name>mongodb</server_name> <tool_name>read_resource</tool_name>

{ "uri": "mongodb://localhost:27017/common" }

</use_mcp_tool>

CallToolRequestSchema、ReadResourceRequestSchema 的区别

CallToolRequestSchema： 用于执行特定操作 适合执行命令、处理数据等主动操作 示例：获取集合列表、插入数据等

ReadResourceRequestSchema： 用于读取资源内容 适合提供对资源的只读访问 示例：读取集合文档、获取数据库状态等

多表联查示例

<use_mcp_tool> <server_name>mongodb</server_name> <tool_name>multi_collection_query</tool_name>

{ "database": "common", "collection": "players", "pipeline": [ { "$lookup": { "from": "platform", "localField": "platform", "foreignField": "appKey", "as": "platformInfo" } }, { "$unwind": "$platformInfo" }, { "$project": { "_id": 1, "pid": 1, "__v": 1, "bank": 1, "ip": 1, "lobbyUrl": 1, "platform": "$platformInfo", "rtp": 1, "_collection": { "$literal": "players" } } }, { "$limit": 2 } ] }
