| Configure MongoDB MCP connection |
MongoDB Tools Setup
Source: mongodb-js/mongodb-mcp-server
Configure the MongoDB MCP server with your connection string.
Step 1: Check Current Status
Read the MCP configuration from ${CLAUDE_PLUGIN_ROOT}/.mcp.json.
Check if MongoDB is configured:
- If
mongodb.env.MDB_MCP_CONNECTION_STRINGcontainsREPLACE_WITH_CONNECTION_STRING, it needs configuration - If it contains a value starting with
mongodb://ormongodb+srv://, already configured
Report status:
- "MongoDB MCP is not configured - needs a connection string"
- OR "MongoDB MCP is already configured"
Step 2: Show Setup Guide
Tell the user:
To configure MongoDB MCP, you need a connection string.
Formats:
- Atlas: mongodb+srv://username:password@cluster.mongodb.net/database
- Local: mongodb://localhost:27017/database
Get Atlas connection string:
1. Go to cloud.mongodb.com
2. Navigate to your cluster
3. Click "Connect" → "Drivers"
4. Copy connection string
Note: MCP runs in READ-ONLY mode.
Don't need MongoDB MCP? Disable it via /mcp command.
Step 3: Ask for Connection String
Use AskUserQuestion:
- question: "Do you have your MongoDB connection string ready?"
- header: "MongoDB"
- options:
- label: "Yes, I have it" description: "I have my MongoDB connection string ready to paste"
- label: "No, skip for now" description: "I'll configure it later"
If user selects "No, skip for now":
- Tell them they can run
/mongodb-tools:setupagain when ready - Remind them they can disable MongoDB MCP via
/mcpif not needed - Exit
If user selects "Yes" or provides connection string via "Other":
- If they provided connection string in "Other" response, use that
- Otherwise, ask them to paste the connection string
Step 4: Validate Connection String
Validate the provided connection string:
- Must start with
mongodb://ormongodb+srv://
If invalid:
- Show error: "Invalid connection string format. Must start with 'mongodb://' or 'mongodb+srv://'"
- Ask if they want to try again or skip
Step 5: Update Configuration
- Read current
${CLAUDE_PLUGIN_ROOT}/.mcp.json - Create backup at
${CLAUDE_PLUGIN_ROOT}/.mcp.json.backup - Update
mongodb.env.MDB_MCP_CONNECTION_STRINGvalue to the actual connection string - Write updated configuration back to
${CLAUDE_PLUGIN_ROOT}/.mcp.json
Step 6: Confirm Success
Tell the user:
MongoDB MCP configured successfully!
IMPORTANT: Restart Claude Code for changes to take effect.
- Exit Claude Code
- Run `claude` again
To verify after restart, run /mcp and check that 'mongodb' server is connected.
Troubleshooting
If MongoDB MCP fails after configuration:
Common fixes:
1. Authentication failed - Add ?authSource=admin to connection string
2. Network timeout - Whitelist IP in Atlas Network Access settings
3. Wrong credentials - Verify username/password, special chars need URL encoding
4. SSL/TLS errors - For Atlas, ensure mongodb+srv:// is used
