📖 EventCatalog - MCP Server Save time and money by getting insights from your EventCatalog directly from your MCP Client (Claude, Cursor, Windsurf, etc)
-->
Features: Ask about domains, services and messages. Get answers in seconds. Request schemas, who owns what and much more.
EventCatalog is an Open Source tool that helps you document your event-driven architecture. Using EventCatalog you can document your domains, services and messages, schemas and much more.
Using the EventCatalog MCP Server you can get more value from your EventCatalog by asking questions about your architecture in the tools you already use.
Example questions:
UserCreated
in EventCatalog.UserCreated
schema, what downstream consumers will be affected by this change?Rather then digging through your architecture to find the answers you need, you can ask the MCP server directly from your MCP Client.
First, you need to enable the LLMS.txt
feature in your EventCatalog instance.
LLMS.txt
feature in your EventCatalog instance, by configuring your eventcatalog.config.js
file.LLMS.txt
feature enabled.Next, you will need to get a EventCatalog Scale license key, you can get a 14 day trial license key from EventCatalog Cloud.
To install EventCatalog for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install @event-catalog/mcp-server --client claude
Each MCP client has a different way of adding the MCP server.
You can find some helpful links below to get started.
To use this with Claude Desktop, add the following to your claud_desktop_config.json
file. The full path on MacOS: ~/Library/Application Support/Claude/claud_desktop_config.json
, on Windows: %APPDATA%\Claude\claud_desktop_config.json
{ "mcpServers": { "eventcatalog": { "command": "npx", "args": [ "-y", "@eventcatalog/mcp-server", "https://demo.eventcatalog.dev", // Replace with your EventCatalog URL "ABCD-1234-5678-9012-3456-7890" // Replace with your EventCatalog Scale license key ] } } }
Go to Cursor Settings -> MCP Servers -> Add MCP Server.
eventcatalog
npx
-y @eventcatalog/mcp-server {URL_TO_YOUR_EVENTCATALOG_INSTANCE}
You can also create .mcp.json
files in your project to configure the MCP server for your project using Cursor.
{ "mcpServers": { "eventcatalog": { "command": "npx", "args": ["-y", "@eventcatalog/mcp-server", "https://demo.eventcatalog.dev", "ABCD-1234-5678-9012-3456-7890"] } } }

We are working on adding more APIs to the MCP server. If you need something specific, please open an issue and we will add it to the server.
pnpm install
to install the dependenciespnpm run build
To use the build as your MCP server you can point your MCP client to the dist
folder.
Example for Cursor:
{ "mcpServers": { "eventcatalog": { "command": "npx", "args": ["-y", "tsx /PATH_TO_YOUR_REPO/src/index.ts", "https://demo.eventcatalog.dev", "ABCD-1234-5678-9012-3456-7890"] } } }
