Query and manage MongoDB databases, collections, documents, aggregations and indexes.

Tools (27):

Tool	Description
`mongodbListDatabases`	List databases on the MongoDB server with sizes. Use to discover what data is available before querying.
`mongodbPingServer`	Ping the MongoDB server to verify connectivity and get server hello metadata. Use to validate the connection.
`mongodbListCollections`	List collections (and views) in a database with their types. Use to discover queryable collections.
`mongodbDatabaseStats`	Get database storage stats: data size, index size, collection and object counts. Use for capacity review.
`mongodbCollectionStats`	Get collection stats: document count, sizes, index details and shard info. Use to inspect a collection before heavy queries.
`mongodbCreateCollection`	Create a new collection, optionally capped or with a JSON-schema validator. Use before inserting into a fresh namespace.
`mongodbDropCollection`	Drop a collection and all its documents and indexes. Irreversible — confirm with the user first.
`mongodbRenameCollection`	Rename a collection within its database. Updates the namespace; indexes move with it.
`mongodbFindDocuments`	Find documents with filter, projection, sort, skip and limit. Defaults to 50 docs (max 1000). Use for reads and exploration.
`mongodbFindOne`	Find the first document matching a filter. Use for fetching a single record by id or unique key.
`mongodbInsertOne`	Insert a single document into a collection. Returns the generated _id.
`mongodbInsertMany`	Insert multiple documents in one batch (max 1000 per call). Returns inserted ids.
`mongodbUpdateOne`	Update the first document matching a filter with $set/$inc/etc. Supports upsert.
`mongodbUpdateMany`	Update all documents matching a filter. Use for bulk status changes and migrations.
`mongodbReplaceOne`	Replace a whole document (keeping _id) with a new one. Supports upsert.
`mongodbDeleteOne`	Delete the first document matching a filter.
`mongodbDeleteMany`	Delete all documents matching a filter. Returns the deleted count — confirm scope with the user first on broad filters.
`mongodbFindOneAndUpdate`	Atomically update one document and return it (before or after the change). Use for counters, reservations and read-modify-write.
`mongodbFindOneAndDelete`	Atomically delete one document and return it. Use for queue-style claim-and-remove patterns.
`mongodbBulkWrite`	Run mixed insert/update/delete operations in one batch for efficiency.
`mongodbAggregate`	Run an aggregation pipeline ($match, $group, $lookup, $unwind, …) for analytics and reports.
`mongodbCountDocuments`	Count documents matching a filter exactly (scans the collection). Use for filtered totals.
`mongodbEstimatedDocumentCount`	Fast estimated collection size from metadata (no filter). Use for quick size checks on large collections.
`mongodbDistinct`	List distinct values of a field, optionally filtered. Use for dropdowns, facets and cardinality checks.
`mongodbCreateIndex`	Create an index (single, compound, text, geospatial, TTL) to speed queries and enforce uniqueness.
`mongodbListIndexes`	List indexes on a collection with keys, uniqueness and sizes. Use to review query coverage.
`mongodbDropIndex`	Drop an index by name (use "*" for all non-_id indexes). Use to remove unused or blocking indexes.
