Does it support MongoDB Atlas?

Yes — pass the standard SRV connection string from the Atlas UI. The MCP also wraps Atlas Admin endpoints when you provide an Atlas API key, but you can run pure-data workflows without those scopes.

Read-only or read-write?

Both. Read-only is the safe default. Pass --readOnly=false (or set MDB_READ_ONLY=false) to enable insert/update/delete tools — only do this on dev clusters.

How does it infer schema?

It samples a configurable number of documents per collection and returns the union of field types. Useful for the model, but treat the result as a sketch — not a contract.

Can I scope to one database?

Yes. Pass --database= to restrict every tool to that database. Combine with a database user that only has access to that namespace as defence in depth.

Does it support transactions?

No agent-facing transaction tool by design — multi-statement consistency in an LLM conversation is a footgun. Use a regular MongoDB driver for transactional workloads.

Quick answer

What it does

Connects to a MongoDB deployment and exposes database/collection enumeration, schema inspection, find queries, and aggregation pipelines to AI models.

Best for

Collection schema exploration
Aggregation pipeline drafting
Document inspection
Reporting queries

Not for

Transactional multi-document writes
Long-running Change Streams

Setup recipe

Pick your client, then follow the three steps.

Install

claude_desktop_config.jsonjson

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server",
        "--connectionString=\"mongodb+srv://user:pass@cluster.mongodb.net\""
      ],
      "env": {
        "MDB_CONNECTION_STRING": "${MDB_CONNECTION_STRING}"
      }
    }
  }
}

Paste under mcpServers. Fully quit and reopen Claude after editing.

CLI or .mcp.jsonshell

# export MDB_CONNECTION_STRING=mongodb+srv://user:pass@cluster.mongodb.net
claude mcp add mongodb -- npx -y mongodb-mcp-server --connectionString="mongodb+srv://user:pass@cluster.mongodb.net"

Run from your repo. Commit .mcp.json to share with your team.

.cursor/mcp.jsonjson

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server",
        "--connectionString=\"mongodb+srv://user:pass@cluster.mongodb.net\""
      ],
      "env": {
        "MDB_CONNECTION_STRING": "${MDB_CONNECTION_STRING}"
      }
    }
  }
}

Global path: ~/.cursor/mcp.json. Reload window after editing.

.vscode/mcp.jsonjsonc

{
  "servers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server",
        "--connectionString=\"mongodb+srv://user:pass@cluster.mongodb.net\""
      ],
      "env": {
        "MDB_CONNECTION_STRING": "${MDB_CONNECTION_STRING}"
      }
    }
  }
}

VS Code uses the "servers" key (not "mcpServers").

~/.codeium/windsurf/mcp_config.jsonjson

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server",
        "--connectionString=\"mongodb+srv://user:pass@cluster.mongodb.net\""
      ],
      "env": {
        "MDB_CONNECTION_STRING": "${MDB_CONNECTION_STRING}"
      }
    }
  }
}

Open via Cascade → hammer icon → Configure.

cline_mcp_settings.jsonjson

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": [
        "-y",
        "mongodb-mcp-server",
        "--connectionString=\"mongodb+srv://user:pass@cluster.mongodb.net\""
      ],
      "env": {
        "MDB_CONNECTION_STRING": "${MDB_CONNECTION_STRING}"
      }
    }
  }
}

Open via the Cline sidebar → MCP Servers → Edit.

~/.continue/config.jsonjson

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "npx",
          "args": [
            "-y",
            "mongodb-mcp-server",
            "--connectionString=\"mongodb+srv://user:pass@cluster.mongodb.net\""
          ],
          "env": {
            "MDB_CONNECTION_STRING": "${MDB_CONNECTION_STRING}"
          }
        }
      }
    ]
  }
}

Continue uses modelContextProtocolServers with a transport block.

~/.codex/config.tomlshell

# ~/.codex/config.toml
[mcp_servers.mongodb]
command = "npx"
args = [
  "-y",
  "mongodb-mcp-server",
  "--connectionString=\"mongodb+srv://user:pass@cluster.mongodb.net\"",
]
env = { MDB_CONNECTION_STRING = "${MDB_CONNECTION_STRING}" }

Codex uses TOML. Each server is a [mcp_servers.<name>] subtable.

~/.config/zed/settings.jsonjsonc

{
  "context_servers": {
    "mongodb": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "mongodb-mcp-server",
          "--connectionString=\"mongodb+srv://user:pass@cluster.mongodb.net\""
        ]
      },
      "env": {
        "MDB_CONNECTION_STRING": "${MDB_CONNECTION_STRING}"
      }
    }
  }
}

Zed calls them "context_servers". Settings live-reload on save.

ChatGPT → Apps directorynone

MongoDB doesn't ship a hosted HTTPS endpoint today. ChatGPT supports remote MCP servers only — to use this server in ChatGPT you'll need to deploy it to a public HTTPS URL first (e.g. via Cloudflare Workers or Vercel) or wait for an official remote build.

Tools & permissions

Tool	Description	Args	Side effects
`list_databases`	List databases on the cluster.	—	Read
`list_collections`	List collections within a database.	database: string	Read
`find`	Run a find query against a collection.	collection: string, filter?: object	Read
`aggregate`	Run an aggregation pipeline.	collection: string, pipeline: array	Read

Security & scope

Access scope: Read-only
Sandbox: Connects via standard MongoDB driver to the connection string in MDB_CONNECTION_STRING. Read-only mode disables write tools at the MCP layer; combine with a database user scoped to the smallest namespace your workflow needs.
Gotchas: Read-only is enforced at the tool level, not the MongoDB role. Always pair MCP read-only mode with a read-only database user.
Schema inference samples N documents; rare fields may be missing from the inferred schema.
The Atlas Admin tools require a separate Atlas API key — do not reuse the connection-string password for admin scope.

Agent prompt pack

— copy into Claude, Cursor, or ChatGPT.

Paste into Claude, Cursor, or ChatGPT. Edit the [brackets] before sending.

Recommend the best MCP servers for [task: e.g. databases work] in [client: Claude].

Constraints:
- Prefer tools that are [official | open-source | read-only] — pick what matters for my use case.
- Exclude MCPs that require [e.g. a paid plan, OAuth-only flows, remote-only transport].
- Return at most 3 picks, ranked.

For each pick include:
1. One-sentence rationale.
2. The ready-to-paste install snippet for my client.
3. Any required secrets I need to create before installing.

Cross-check the top-mcps.com listing: https://top-mcps.com/top-mcps-for-databases

Compare MongoDB against a real alternative. Swap the second MCP in [brackets] if you want a different match.

Compare MongoDB MCP vs [Postgres MCP Pro MCP] for the following job: [describe the job, e.g. "let an agent create GitHub issues on bug triage"].

Judge them on:
- Setup time and complexity (what a new user hits first).
- Auth model (none / API key / OAuth 2.1) and credential risk.
- Transport (stdio / Streamable HTTP / SSE) and where the server runs.
- Required secrets and the blast radius if they leak.
- Operational risk in an unattended agent loop.
- Which one is "good enough" for a weekend prototype vs. production.

End with one sentence: which should I pick for my scenario, which is: [my scenario].

Asks the agent to install and verify. Works inside Claude Code, Cursor Agent, Codex CLI.

Install the MongoDB MCP server for my [client: Claude] at the default config path for that client.

Use the exact install snippet published at https://top-mcps.com/mcp/mongodb (fetch https://top-mcps.com/mcp/mongodb.json for the canonical server.json if you can read URLs).

Before finishing:
1. Create the required secrets (MDB_CONNECTION_STRING) and put them in the appropriate env block — do not hard-code them.
2. Restart or reload the client so it picks up the new server.
3. Verify the server is connected (green / running state) and at least one tool is listed.
4. If anything fails, read the client's MCP logs and report the exact error — do not silently retry.

Confirm when done and list the tools the server now exposes.
