EventCatalog MCP

What it does

The EventCatalog MCP Server allows AI assistants to interact directly with your EventCatalog instance. It provides deep visibility into event-driven architectures, enabling users to ask questions about domains, services, messages, and ubiquitous language without leaving their IDE or chat client.

Tools

• find_resources: Search for services, domains, events, and flows.
• get_schema: Retrieve OpenAPI, AsyncAPI, or JSON schemas for events and services.
• find_owners: Identify the teams or users responsible for specific architectural components.
• find_producers_and_consumers: Map out the message flow and dependencies between services.
• review_schema_changes: Analyze new schemas for breaking changes and suggest fixes.
• eventstorm_to_eventcatalog: Convert EventStorming session images into structured catalog entries.
