About Mcp Mongodb
Mcp Mongodb is an MCP server project for working with MongoDB databases. Its examples distinguish tool-based operations from read-only resource access and include a multi-collection aggregation query.
Key features
- 01MongoDB resource reads
- 02Collection-list and insert operations
- 03Multi-collection aggregation query
Use cases
- 01Reading database resources
- 02Listing collections or inserting data
- 03Joining collections with an aggregation pipeline
MCP support
The MCP server exposes MongoDB operations as tools and read-only database content as resources. The README includes a resource URI example and a multi-collection query tool example.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

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 } ] }

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
