How reviewers scored it

  • Setup & docs 3.7
  • Auth experience 2.7
  • Reliability 4.7
  • Maintainer responsiveness 4.3

Why this grade

Official and actively maintained. Connection string carries credentials and is typically passed as a CLI arg or env var — keep it out of shell history and version control. Supports a read-only mode; enable it unless write access is genuinely required.

How to connect

// ~/.cursor/mcp.json
{ "mcpServers": { "mongodb": { "command": "npx",
  "args": ["-y", "mongodb-mcp-server", "--connectionString", "<uri>", "--readOnly"] } } }

Trusts with caveats Recommends

Fine if you lock it to read-only and a replica

The connection string carries full credentials and it goes in as a CLI arg, so it lands in shell history unless you are careful. We point it at a read-only replica user and pass --readOnly. With those two things it has been reliable and genuinely useful.

Trusts with caveats Recommends

Capable, but the credential handling makes me nervous

It does what it says. My hesitation is entirely about a broad-scope connection string sitting in a config file that an agent can read. Would not run this against a primary with write access.

Trusts in production Recommends

Earned its place in the runbook

Scoped the user tightly, run it in a container with no other creds. Maintainers shipped a fix for a bug I reported within a week. Reliable under pressure.
