Side-by-side comparison

The AgentRank database category covers 910 repositories. Both the MongoDB and Neon servers are official vendor-maintained tools — unusual in a space where most MCP servers are community projects. The 9.86-point score gap (88.44 vs 78.58) reflects MongoDB's higher star count and contributor depth.

Data from March 19, 2026 crawl. Score = composite of stars 15%, freshness 25%, issue health 25%, contributors 10%, inbound dependents 25%.

MongoDB MCP deep dive

mongodb-js/mongodb-mcp-server — score 88.44

mongodb-js/mongodb-mcp-server is the highest-scoring database MCP server in the AgentRank index. It is maintained by MongoDB Labs — the same team that maintains the official MongoDB Node.js driver. Last commit: March 14, 2026.

The server exposes MongoDB and MongoDB Atlas capabilities to AI agents: collection inspection, document CRUD, aggregation pipelines, schema inference, and Atlas management operations. The Atlas integration is particularly valuable for teams that use Atlas Search, Vector Search, or multi-cloud deployments.

With 25 contributors and 959 stars, it has a healthy open-source profile for a vendor-maintained tool. The issue close rate is not public in our index, but active commits through March 2026 are a strong proxy for responsiveness.

Neon MCP deep dive

neondatabase/mcp-server-neon — score 78.58

neondatabase/mcp-server-neon is Neon's official MCP server for serverless Postgres. It scores 78.58 and was last committed on March 17, 2026 — the most recently updated database tool in the index. Freshness drives a significant portion of the AgentRank score (25% weight), so the March 17 commit is a strong signal.

The server covers two distinct surfaces: the Neon management API (create projects, manage branches, configure compute) and raw SQL execution (run queries against any Neon Postgres database). The branching capability is the differentiator — agents can create database branches for safe testing, then merge back to main. No other database MCP server exposes database branching natively.

17 contributors is lower than MongoDB's 25, which explains part of the score gap. Neon is a smaller company and a newer platform — but the freshness signal (March 17 commit) offsets some of the contributor-count disadvantage.

Verdict

This comparison is not zero-sum — MongoDB and Neon serve different database paradigms. The right choice depends on your data model:

• You use Postgres (or want serverless Postgres): neondatabase/mcp-server-neon — score 78.58, freshest commits, unique branching capability.
• You use MongoDB or Atlas: mongodb-js/mongodb-mcp-server — score 88.44, highest in database category, Atlas integration.
• You use multiple database types: bytebase/dbhub — score 78.12, zero dependencies, supports Postgres, MySQL, SQL Server, MariaDB, and SQLite from a single server.

If your stack is Postgres only and you are not on Neon, look at the other Postgres options in the database category — the full database ranking covers 7 top-scored servers including Redis, DuckDB, and dbt.

Setup guide

Install MongoDB MCP server

Add to your MCP client config (claude_desktop_config.json or .cursor/mcp.json):

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": ["-y", "mongodb-mcp-server"],
      "env": {
        "MDB_MCP_CONNECTION_STRING": "mongodb+srv://..."
      }
    }
  }
}

Install Neon MCP server

{
  "mcpServers": {
    "neon": {
      "command": "npx",
      "args": ["-y", "@neondatabase/mcp-server-neon"],
      "env": {
        "NEON_API_KEY": "your-neon-api-key"
      }
    }
  }
}

Both servers require an account with the respective database provider. MongoDB requires a connection string (Atlas or self-hosted). Neon requires an API key from the Neon console.
