How to Connect MongoDB to Gemini — via MCP

💡 No install? Use cloud.anythingmcp.com directly. Sign in, click Connectors → MongoDB, paste your credentials, mint an MCP API key — done. No Docker, no git clone, no local server.

MongoDB + Gemini

Query a MongoDB database directly: introspect collections and their field shapes, and run read-only find queries with filter, projection, sort and limit. Installs read-only; credentials are held encrypted rather than in the connection string.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

MONGODB_HOST, MONGODB_PORT, MONGODB_DATABASE, MONGODB_USER, MONGODB_PASSWORD, MONGODB_AUTH_SOURCE

Step 1 — Get credentials

Setup

1. Create a user with only read on the database the agent should see:

   use admin
   db.createUser({
     user: "amcp_reader",
     pwd: "change-me",
     roles: [{ role: "read", db: "shop" }]
   })
   

2. Set MONGODB_HOST, MONGODB_PORT (27017), MONGODB_DATABASE, MONGODB_USER and MONGODB_PASSWORD.

MONGODB_AUTH_SOURCE is the field that decides whether this works at all. MongoDB authenticates a user against the database the user was created in, not the one you want to read. A root or admin account created the usual way lives in admin, so MONGODB_AUTH_SOURCE must be admin even though MONGODB_DATABASE is shop. …

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Gemini

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

Gemini CLI reads MCP servers from ~/.gemini/settings.json (or %APPDATA%\gemini\settings.json on Windows). Add:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID",
      "headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
    }
  }
}

1. Get your MCP API key from AnythingMCP → MCP Servers → your server → API keys.
2. Save the file and restart gemini.
3. Run /mcp inside the Gemini CLI — MongoDB should be listed as available.
4. Vertex AI Studio: pass https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID to the tools array of your request with the same X-API-Key header.

FAQ

Does Gemini 1.5 Pro or 2.x support MCP? Yes — Gemini CLI ≥ 0.4 and Vertex AI tools API both accept MCP httpUrl connectors with custom headers.
