mongodb-mcp-vn

# MongoDB MCP VN English | [Tiếng Việt](#tiếng-việt) `mongodb-mcp-vn` is a Python MCP server for bounded MongoDB discovery, read, and explicitly guarded mutation operations. It returns MongoDB Extended JSON and never returns a configured connection URI or driver exception details. ## Install and run Install the released package: ```sh uv tool install mongodb-mcp-vn ``` Or, from a source checkout: ```sh cd uvx/mongodb uv sync --extra dev ``` Set a least-privilege URI outside source control. This local example contains no credentials: ```sh export MONGO_URI='mongodb://localhost:27017' ``` ### stdio (default) Use stdio for a local MCP client such as Codex or Claude Desktop: ```sh MCP_TRANSPORT=stdio mongodb-mcp-vn ``` The equivalent source command is `uv run mongodb-mcp-vn`. ### MCP client JSON configuration (stdio) Add this to your Codex or Claude Desktop MCP configuration. Do not set `MCP_TRANSPORT`; stdio is the default. ```json { "mcpServers": { "mongodb-mcp-vn": { "command": "uvx", "args": ["mongodb-mcp-vn"], "env": { "MONGO_URI": "mongodb://localhost:27017", "MONGO_ALLOW_WRITE": "false" } } } } ``` Set `MONGO_ALLOW_WRITE` to `true` only when the MCP client must create, update, delete documents, or drop a collection; restart the client after changing it. Tool inputs are direct JSON fields: call `mongodb_ping` with `{}`, and call `mongodb_list_databases` with `{"limit": 50}`. Do not wrap them in `params`. ### Streamable HTTP Use streamable HTTP only behind an appropriate network boundary. The defaults are `127.0.0.1:8005`; `streamable_http` is accepted as an alias. ```sh MCP_TRANSPORT=streamable-http MCP_HOST=127.0.0.1 MCP_PORT=8005 mongodb-mcp-vn ``` `MCP_PORT` must be an integer from 1 through 65535. Unsupported transports fail at startup rather than silently changing transport. ## Tools All collection and database names preserve the supplied bytes; blank-only names are rejected. Read to…
