Best MongoDB MCP Servers

A Model Context Protocol Server for MongoDB

PostGraphile is an automated tool that converts a PostgreSQL database schema into a fully functional GraphQL API. It serves as a GraphQL execution engine and schema orchestrator, utilizing database schema introspection to retrieve strongly typed metadata directly from PostgreSQL. The project features a modular system for composing and standardizing GraphQL schemas through plugins, which manage naming conventions and connections. It includes a PostgreSQL query builder that constructs dynamic, SQL-injection-proof queries using tagged template literals. The system employs a declarative query pl

The MongoDB Node.js Driver is a programmatic interface and NoSQL database client used to manage document storage and execute operations within a MongoDB database. It serves as an asynchronous database interface and connection manager that enables Node.js applications to integrate with MongoDB servers. The project implements client-side field encryption to secure sensitive data and queries locally before transmission. It also provides a BSON serialization library to convert JavaScript objects into a binary format for efficient storage and network transmission. The driver covers a broad range

EdgeDB is a graph-relational database that combines a PostgreSQL backend with a graph-based schema and query language. It functions as an object-relational mapper and graph query engine, allowing data to be modeled as objects and links to align storage with modern programming language structures. The system features a composable query language designed to retrieve deeply nested or interconnected data without the use of manual SQL joins. It includes an integrated AI-driven data retrieval solution with built-in support for vector embeddings. The platform provides a schema migration tool for tr

Directus is a headless content platform that functions as a backend service, automatically generating REST and GraphQL APIs by performing introspection on existing SQL database schemas. It serves as a unified data orchestration layer, decoupling content management from frontend delivery while providing a secure, stateless gateway for database transactions. The platform distinguishes itself through a granular role-based access control engine that enforces security policies at the field level across all API endpoints. It includes a visual, low-code administrative dashboard that allows non-techn

Mongoid is an object-document mapper for Ruby that translates Ruby objects into MongoDB documents. It serves as a document database mapper and client library, providing a structured way to manage data persistence and retrieval within a NoSQL environment. The project distinguishes itself by offering advanced data retrieval tools, including vector search for semantic similarity and full-text search for keyword matching. It implements high-security data protection through client-side field-level encryption, encryption key rotation, and TLS connection security to protect sensitive information. B

DBeaver is a universal database client and administration environment designed for managing diverse relational and non-relational database systems. It provides a unified graphical interface that enables users to perform data manipulation, schema migration, and performance monitoring across multiple platforms. By utilizing a standardized driver abstraction layer, the application translates generic requests into database-specific commands, ensuring consistent interaction regardless of the underlying technology. The project distinguishes itself through an extensible, plugin-based architecture th

MongoEngine is a Python object-document mapper that translates database records into objects to provide an object-oriented interface for data persistence. It serves as a document manager and schema validator for MongoDB, mapping classes to documents to enforce data types and validation rules. The project provides a lazy-loaded queryset system for filtering, sorting, and aggregating collections using Pythonic syntax. It manages complex data structures through features such as document inheritance, recursive embedded document handling, and reference-based object linking. The library covers bro

SurrealDB is a multi-model database engine designed to store and query document, graph, relational, and vector data within a single ACID-compliant platform. It functions as an AI-native data store, integrating vector search, graph traversal, and machine learning model execution directly into its query layer. By providing a unified declarative query language, the platform eliminates the need for external middleware to synchronize data across different storage models. The platform distinguishes itself through its ability to manage agent memory and complex workflows natively. It allows developer

LanceDB is a vector database and columnar data store designed to function as a versioned dataset manager and vector search engine. It serves as a high-performance backend for indexing and retrieving high-dimensional embeddings, providing the foundation for machine learning data pipelines. The system distinguishes itself through a combination of cloud-native object storage and immutable version tracking, allowing for data time-travel and reproducible AI experiments. It integrates hybrid search capabilities, merging dense vector similarity with BM25 full-text search and SQL-like scalar filters

CASL is a JavaScript authorization library for defining and enforcing declarative access control rules across both frontend and backend environments. It provides an attribute-based access control system that manages permissions based on user roles and specific object properties. The library is designed for isomorphic access control, allowing a consistent set of permission rules to be shared between a server API and a client interface. It enables the serialization of permission sets as plain data objects to maintain synchronization across these different layers. Its capabilities include trans

This project is a reactive, offline-first NoSQL database engine designed for JavaScript applications. It provides a robust framework for managing application state by synchronizing data across browsers, mobile devices, and server-side runtimes. By treating local storage as the primary source of truth, it enables applications to remain functional without network connectivity, automatically reconciling changes with remote backends once a connection is restored. The database distinguishes itself through a modular architecture that supports cross-environment synchronization and high-performance d
