What can you do with this server?

The Prefect MCP Server enables AI assistants to interact with Prefect's workflow orchestration platform through natural language via the Model Context Protocol (MCP), providing comprehensive management and monitoring capabilities through 45+ API endpoints. Core Capabilities: * Flow Management: List, filter, view, and delete flows; query flow runs with extensive filtering (state, deployment, tags, time ranges); control flow run lifecycle (create, restart, cancel, delete, set states); retrieve flow run details and logs * Deployment Operations: List, filter, view, update, and delete deployments; create flow runs from deployments with custom parameters, names, tags, and idempotency keys; manage deployment schedules (view, set cron/interval-based schedules, pause, resume); configure work queue assignments * Task Run Monitoring: List and filter task runs by name, state, tags, and time ranges; retrieve task run details and logs; query task runs by flow run; manually set task run states with optional messages * Work Queue Operations: Create, list, update, pause, resume, and delete work queues; manage concurrency limits and configuration; filter by name or paused status * Variable Management: Create, read, update, and delete variables with support for string, dict, list, or other JSON-serializable values; manage variable tags; filter by name with pagination * Block Management: List available block types with slug-based filtering; retrieve block type schemas; query, retrieve, and delete block documents (configuration instances) * Workspace Management: List accessible workspaces; get current workspace context; retrieve workspace details by ID or handle * Artifact Management: Perform CRUD operations on Prefect artifacts * Automation Control: Create, view, update, delete, pause, and resume automations * System Monitoring: Check Prefect server health status and connectivity; create and retrieve logs for debugging Key Features: Comprehensive filtering on most operations (tags, names, states, dates), pagination support with limit/offset, UUID-based precise resource targeting, tag-based organization, and state management with custom messages.

Which integrations are available for this server?

Allows AI assistants to interact with Prefect through natural language, providing access to flow management, flow run management, deployment management, task run monitoring, work queue management, block management, variable management, and workspace information.

How do I use Prefect MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Prefect MCP Server show me my recent flow runs and their statuses" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.
