Available BullMQ MCP Tools

Connection Management

• connect - Connect to a Redis instance

  { id: string, // Connection identifier url?: string, // Redis URL (e.g., redis://user:pass@localhost:6379/0) host?: string, // Redis host (default: localhost) - ignored if url is provided port?: number, // Redis port (default: 6379) - ignored if url is provided password?: string, // Redis password (optional) - ignored if url is provided db?: number // Redis database number (default: 0) - ignored if url is provided }

  The tool will use the Redis URL in this order of preference:

  1. url parameter if provided

  2. REDIS_URL environment variable if set

  3. Individual connection parameters (host, port, password, db)

  Docker Auto-redirect: When running in a Docker container (detected via DOCKER env variable or DOCKER_HOST), localhost will automatically redirect to host.docker.internal to connect to Redis on the host machine.

• disconnect - Disconnect from current Redis instance

• list_connections - List all saved connections

• switch_connection - Switch to a different connection

  { id: string // Connection identifier to switch to }

Queue Management

• list_queues - List all queues in the current connection

  { pattern?: string // Queue name pattern (supports wildcards, default: "*") }

• stats - Get queue statistics

  { queue: string // Queue name }

• pause_queue - Pause queue processing

  { queue: string // Queue name }

• resume_queue - Resume queue processing

  { queue: string // Queue name }

• drain_queue - Remove all jobs from a queue

  { queue: string // Queue name }

• clean_queue - Clean jobs from queue

  { queue: string, // Queue name grace?: number, // Grace period in milliseconds (default: 0) limit?: number, // Maximum number of jobs to clean (default: 1000) status?: "completed" | "failed" // Job status to clean (default: "completed") }

Job Management

• get_jobs - Get jobs from queue by status

  { queue: string, // Queue name status: "active" | "waiting" | "completed" | "failed" | "delayed" | "paused" | "repeat" | "wait", start?: number, // Start index (default: 0) end?: number // End index (default: 10) }

• get_job - Get a specific job by ID

  { queue: string, // Queue name jobId: string // Job ID }

• add_job - Add a new job to the queue

  { queue: string, // Queue name name: string, // Job name data: object, // Job data (JSON object) opts?: { // Job options delay?: number, // Delay in milliseconds priority?: number, // Job priority attempts?: number, // Number of attempts backoff?: object, // Backoff configuration removeOnComplete?: boolean, // Remove job when completed removeOnFail?: boolean // Remove job when failed } }

• remove_job - Remove a job from the queue

  { queue: string, // Queue name jobId: string // Job ID }

• retry_job - Retry a failed job

  { queue: string, // Queue name jobId: string // Job ID }

• promote_job - Promote a delayed job

  { queue: string, // Queue name jobId: string // Job ID }

Job Logs

• get_job_logs - Get logs for a job

  { queue: string, // Queue name jobId: string // Job ID }

• add_job_log - Add a log entry to a job

  { queue: string, // Queue name jobId: string, // Job ID message: string // Log message }

BullMQ MCP Examples - How to Use BullMQ with Claude

Connect to Redis and List Queues

Add and Monitor a Job

Queue Maintenance

Advanced Job Management

Getting Started with BullMQ MCP

Prerequisites

1. Redis Server: Ensure Redis is running locally or accessible remotely

   # Check if Redis is running redis-cli ping # Should return: PONG

2. Claude Desktop: Install and configure Claude Desktop with the BullMQ MCP server

Basic Workflow

1. Connect to Redis

   Connect to Redis using the bullmq tool with id "local"

2. Explore Queues

   List all queues and show me their statistics

3. Monitor Jobs

   Show me failed jobs in the email-queue

4. Manage Jobs

   Add a test job to my-queue with some sample data

Docker Usage Notes

When using the Docker version:

• Redis Connection: The server automatically redirects localhost to host.docker.internal when running in Docker, so you can use either:

  • redis://localhost:6379 (will auto-redirect)

  • redis://host.docker.internal:6379 (explicit Docker host)

• Connection Timeout: Connections have a 10-second timeout to prevent hanging on unreachable hosts

• Environment Variables: Set REDIS_URL=redis://localhost:6379 - it will auto-redirect in Docker

• Network Access: The Docker container needs network access to reach your Redis instance

• Persistence: The container is ephemeral - all data is stored in Redis, not the container

Common BullMQ MCP Use Cases

1. Monitoring Queue Health

2. Debugging Failed Jobs

3. Retrying Failed Jobs

4. Queue Maintenance

5. Managing Multiple Environments

Testing the Connection

After configuring Claude Desktop, restart Claude and test the connection:

1. Open Claude Desktop

2. Start a new conversation

3. Test the MCP connection:

If successful, you should see a confirmation message. You can then:

• List all available queues

• Check queue statistics

• View job details

• Perform queue operations

Development

Troubleshooting

Connection Issues

• Redis not running: Ensure Redis is running on the specified host and port

  # Start Redis (macOS with Homebrew) brew services start redis # Start Redis (Linux) sudo systemctl start redis # Test connection redis-cli ping

• Authentication failed: Check that the Redis password (if any) is correct

  # Test with password redis-cli -a yourpassword ping

• Wrong database: Ensure you're connecting to the correct Redis database number

Common Errors

• "No active connection": Use the connect tool first before other operations

  First connect to Redis with: connect to Redis using bullmq with id "local"

• "Job not found": Ensure the job ID exists in the specified queue

  List jobs in the queue first to see available job IDs

• "Queue not found": The queue may not exist or have any jobs yet

  List all queues to see what's available

• Connection timeout: Check firewall settings and Redis bind address

  # Check Redis config grep "^bind" /etc/redis/redis.conf

MCP Server Issues

• Server not starting: Check Claude Desktop configuration file syntax

• Tools not available: Restart Claude Desktop after configuration changes

• Permission denied: Ensure the MCP server has execute permissions

Debugging

1. Enable verbose logging in Claude Desktop:

   • Run Claude from terminal to see logs

   • macOS: /Applications/Claude.app/Contents/MacOS/Claude

   • Windows: Run Claude from Command Prompt

   • Linux: Run from terminal

2. Test the MCP server directly:

   # Run the server manually to check for errors npx @adamhancock/bullmq-mcp

3. Check Redis connection:

   # Test Redis connectivity redis-cli -h localhost -p 6379 ping # Check Redis info redis-cli info clients

4. Verify environment variables:

   # Check if REDIS_URL is set echo $REDIS_URL

Requirements

• Node.js 18+

• Redis server

• BullMQ-compatible Redis setup
