Mongodb Mcp Server
mongodb-js/mongodb-mcp-serverOfficial
The MongoDB MCP Server provides LLM-based access to MongoDB databases by exposing tools for querying, inserting, updating, and deleting documents through the Model Context Protocol. It enables AI assistants to interact with MongoDB instances by accepting a connection string and offering read-only or read-write operations depending on configuration. This server solves the problem of integrating database operations into AI workflows by allowing language models to perform structured data manipulation without direct code execution.

MDB_MCP_AGGREGATION_COUNT_MAX_TIME_MS_CAPDeprecated. Use `aggregationCountTimeoutMs` instead.
MDB_MCP_AGGREGATION_COUNT_TIMEOUT_MSThe maximum time in milliseconds for the count phase of aggregation operations. This is used to limit the time spent counting documents when determining if results were capped.
MDB_MCP_ALLOW_REQUEST_OVERRIDESWhen set to true, allows configuration values to be overridden via request headers and query parameters.
MDB_MCP_API_CLIENT_IDsecretAtlas API client ID for authentication. Required for running Atlas tools.
MDB_MCP_API_CLIENT_SECRETsecretAtlas API client secret for authentication. Required for running Atlas tools.
MDB_MCP_ASSISTANT_BASE_URLBase URL for the MongoDB Assistant API.
MDB_MCP_ATLAS_TEMPORARY_DATABASE_USER_LIFETIME_MSTime in milliseconds that temporary database users created when connecting to MongoDB Atlas clusters will remain active before being automatically deleted.
MDB_MCP_CONFIRMATION_REQUIRED_TOOLSComma separated values of tool names that require user confirmation before execution. Requires the client to support elicitation.
MDB_MCP_CONNECTION_IDLE_TIMEOUT_MSMilliseconds a MongoDB connection may stay unused (no tool call touching it) before it is closed to release the underlying connection pool and its server-side state. Applied per connection regardless of its connection scope; the preconfigured connection is excluded, and the reape
MDB_MCP_CONNECTION_SCOPEVisibility scope for MongoDB connections created at runtime. With 'session' (the default), each MCP session only sees the connections it created (plus the shared 'preconfigured' one) and they are closed when the session ends. With 'global', connections are shared across all sessi
MDB_MCP_CONNECTION_STRINGsecretMongoDB connection string for direct database connections, exposed under the connectionId "preconfigured". Optional, if not set, you'll need to call the connect tool before interacting with MongoDB data. Deprecated: prefer the "preconfigured" entry of connectionStrings.
MDB_MCP_CONNECTION_STRINGSsecretMongoDB connection strings keyed by name, as a JSON object (e.g. {"preconfigured": "mongodb://...", "analytics": "mongodb://..."}). Each name becomes a connectionId that the MongoDB tools can use directly, so one server can reach several deployments. Connections are opened on fir
MDB_MCP_DANGEROUS_HOST_BINDINGWhen set to true, allows binding the HTTP server (and monitoring server) to a non-loopback host such as 0.0.0.0, a LAN IP, or an empty host (all interfaces). Binding to a non-loopback host exposes the server to the entire network and can allow unauthorized access. Off by default:
MDB_MCP_DISABLE_SERVER_SIDE_JSWhen set to true, disallows the use of server-side JavaScript operators (such as $where, $function, and $accumulator) in query filters and aggregation pipelines.
MDB_MCP_DISABLE_UNTRUSTED_DATA_WARNINGWhen set to true, tool responses include potentially untrusted data (such as documents or query results) as-is, without wrapping it in delimiters and a prompt-injection warning.
MDB_MCP_DISABLED_TOOLSComma separated values of tool names, operation types, and/or categories of tools that will be disabled.
MDB_MCP_DRY_RUNWhen true, runs the server in dry mode: dumps configuration and enabled tools, then exits without starting the server.
MDB_MCP_ELICITATION_TIMEOUT_MSTime in milliseconds the user has to respond to an elicitation request (such as a tool confirmation prompt) before it fails.
MDB_MCP_EVICTION_IDLE_GRACE_M_SHow long a session must be idle before it becomes eligible for least-recently-used eviction when the HTTP transport is at its maxSessions cap (only used when transport is 'http'). Swept back to idleTimeoutMs when larger.
MDB_MCP_EXPORT_CLEANUP_INTERVAL_MSTime in milliseconds between export cleanup cycles that remove expired export files.
MDB_MCP_EXPORT_TIMEOUT_MSTime in milliseconds after which an export is considered expired and eligible for cleanup.
MDB_MCP_EXPORTS_PATHFolder to store exported data files.
MDB_MCP_EXTERNALLY_MANAGED_SESSIONSWhen true, the 2025-era HTTP transport accepts a session ID supplied externally through the 'mcp-session-id' header. When an external ID is supplied, the initialization request is optional, and an implicitly re-initialized session restores the client's previously negotiated capab
MDB_MCP_HEALTH_CHECK_HOSTDeprecated. Use `monitoringServerHost` instead. Host address to bind the healthCheck HTTP server to (only used when transport is 'http'). If provided, `healthCheckPort` must also be set.
