Prefect MCP Server Integration

What does “Prefect” MCP Server do?

The Prefect MCP (Model Context Protocol) Server acts as a bridge between AI assistants and the Prefect workflow orchestration platform. By exposing Prefect APIs through MCP, it enables AI clients to manage, monitor, and control Prefect workflows and related resources using natural language commands. This integration allows for automated flow management, deployment scheduling, task monitoring, and more—all through AI-powered interfaces. The Prefect MCP Server enhances development workflows by offering tools for querying workflow states, triggering deployments, managing variables, and interacting with all major components of Prefect programmatically or via conversational agents.

List of Prompts

No prompt templates are mentioned or included in the repository or documentation.

List of Resources

No explicit MCP “resources” are listed or described in the available documentation or code. The server exposes Prefect’s entities (flows, runs, deployments, etc.) via its APIs, but no resource primitives are documented.

List of Tools

• Flow Management: List, get, and delete flows.
• Flow Run Management: Create, monitor, and control flow runs.
• Deployment Management: Manage deployments and their schedules.
• Task Run Management: Monitor and control task runs.
• Work Queue Management: Create and manage work queues.
• Block Management: Access block types and documents.
• Variable Management: Create and manage variables.
• Workspace Management: Get information about workspaces.

Use Cases of this MCP Server

• Automated Workflow Management: Developers and operators can list, trigger, and monitor Prefect flows or deployments through AI agents, streamlining repetitive or complex orchestration tasks.
• Flow Run Monitoring and Troubleshooting: Instantly check the status of recent runs, identify failed flows, and take remediation actions (like restarting or deleting runs) via conversational interfaces.
• Deployment Scheduling and Control: Pause, resume, or trigger deployment schedules directly from chat-based assistants, accelerating response to changing business needs.
• Variable and Configuration Management: AI can assist in listing, creating, or updating variables and configurations, reducing manual errors and improving auditability.
• Work Queue and Task Management: Administrators can manage work queues and monitor tasks in real-time, helping balance workloads and maintain high system reliability.

How to set it up

Windsurf

1. Ensure you have Docker and Windsurf prerequisites set up.
2. Export required environment variables:

   export PREFECT_API_URL="http://localhost:4200/api"
   export PREFECT_API_KEY="your_api_key"
   

3. Add the Prefect MCP server to your configuration (e.g., in a JSON config file):

   {
     "mcpServers": {
       "mcp-prefect": {
         "command": "mcp-prefect",
         "args": ["--transport", "sse"],
         "env": {
           "PYTHONPATH": "/path/to/your/project/directory"
         },
         "cwd": "/path/to/your/project/directory"
       }
     }
   }
   

4. Start the server: docker compose up
5. Verify the server is running and that your AI tools can access it.

Securing API Keys:
Use environment variables as above (see env in JSON config) to protect sensitive information.

Claude

1. Make sure the Claude integration supports external MCP servers.
2. Set your Prefect API environment variables as above.
3. Edit the Claude integration config to add the Prefect MCP server:

   {
     "mcpServers": {
       "mcp-prefect": {
         "command": "mcp-prefect",
         "args": ["--transport", "sse"],
         "env": {
           "PYTHONPATH": "/path/to/your/project/directory"
         },
         "cwd": "/path/to/your/project/directory"
       }
     }
   }
   

4. Restart Claude or reload the MCP integration.
5. Test by issuing a Prefect-related command through Claude.

Cursor

1. Install Docker and ensure Cursor’s MCP integration is enabled.
2. Set Prefect-related environment variables.
3. Add the MCP server to Cursor’s config (JSON example):

   {
     "mcpServers": {
       "mcp-prefect": {
         "command": "mcp-prefect",
         "args": ["--transport", "sse"],
         "env": {
           "PYTHONPATH": "/path/to/your/project/directory"
         },
         "cwd": "/path/to/your/project/directory"
       }
     }
   }
   

4. Launch the server: docker compose up
5. Confirm integration by running a test command.

Cline

1. Install and configure Cline per its documentation.
2. Export PREFECT_API_URL and PREFECT_API_KEY.
3. Add the MCP server to your Cline configuration using a JSON object as above.
4. Save the configuration and restart Cline.
5. Verify connectivity and run a sample Prefect command.

Securing API Keys with Environment Variables Example:

{
  "mcpServers": {
    "mcp-prefect": {
      "command": "mcp-prefect",
      "args": ["--transport", "sse"],
      "env": {
        "PREFECT_API_URL": "http://localhost:4200/api",
        "PREFECT_API_KEY": "your_api_key"
      }
    }
  }
}

How to use this MCP inside flows

Using MCP in FlowHunt

To integrate MCP servers into your FlowHunt workflow, start by adding the MCP component to your flow and connecting it to your AI agent:

Click on the MCP component to open the configuration panel. In the system MCP configuration section, insert your MCP server details using this JSON format:

{ “mcp-prefect”: { “transport”: “streamable_http”, “url”: “https://yourmcpserver.example/pathtothemcp/url" } }

Once configured, the AI agent is now able to use this MCP as a tool with access to all its functions and capabilities. Remember to change “mcp-prefect” to whatever the actual name of your MCP server is and replace the URL with your own MCP server URL.

Overview

Our opinion

The Prefect MCP Server provides comprehensive API coverage for Prefect operations and clear setup instructions. However, it lacks documentation for advanced MCP features such as prompt templates, explicit resources, roots, or sampling. Its configuration security is solid, but the absence of prompt and resource definitions reduces its MCP completeness.

MCP Score

Overall Rating:
Given the clear documentation and tool coverage but lack of resource and prompt support, and absence of a LICENSE, I would rate this MCP at 6/10 for completeness and readiness for production MCP use.
