About TalkEventsToMe

TalkEventsToMe is a learning project showing how Cursor and other MCP-compatible clients can query an organization's EventCatalog for event-driven architecture details. It uses the EventCatalog MCP Server to explore resources, schemas, ownership, and event flows.

Key features

  1. 01Queries EventCatalog through MCP
  2. 02Finds resources and detailed records
  3. 03Inspects schemas and schema changes
  4. 04Explores producers, consumers, and event flows
  5. 05Explains domain terminology

Use cases

  1. 01Finding ownership and consumers of an event
  2. 02Reviewing schemas for breaking changes
  3. 03Exploring how services and events relate

MCP support

The project configures the @eventcatalog/mcp-server for use with Cursor and other MCP-compatible clients. It exposes EventCatalog tools for discovery, schema inspection, and terminology, along with catalog resources.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
"mcpServers": {
"TalkEventsToMe": {
"command": "npx",
"args": [
"-y",
"@eventcatalog/mcp-server"
]
}
}
}
Run commandnpx -y @eventcatalog/mcp-server

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Packages
npm@eventcatalog/mcp-server

Tools

No tool list yet

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

TalkEventsToMe

A learning project focused on integrating with EventCatalog via MCP (Model Context Protocol) server to explore event-driven architecture questions and insights.

🎯 Project Purpose

This project demonstrates how to leverage the EventCatalog MCP Server to interact with our organization's EventCatalog instance and get insights about our event-driven architecture directly from AI assistants like Claude, Cursor, and Windsurf.

🏗️ Architecture Overview

  • EventCatalog Instance: https://eventcatalog.compassdigital.org/ (Google OAuth protected)
  • MCP Server: @eventcatalog/mcp-server
  • Client: Cursor IDE with MCP integration
  • Authentication: Requires EventCatalog Scale license key

🚀 Setup Instructions

Prerequisites
  1. EventCatalog Scale License: You'll need a license key for EventCatalog Scale

    • Get a 14-day trial from EventCatalog Cloud
    • Replace YOUR_EVENTCATALOG_SCALE_LICENSE_KEY in .mcp.json
  2. Access to EventCatalog Instance: Ensure you have access to https://eventcatalog.compassdigital.org/

Installation
  1. Configure MCP Server: The .mcp.json file is already configured for this project
  2. Install Dependencies: The MCP server will be installed automatically via npx
  3. Restart Cursor: After updating .mcp.json, restart Cursor to load the MCP server
Verification

Once configured, you should see the EventCatalog MCP server available in Cursor. You can verify by asking questions about your event catalog.

🤖 Available MCP Tools

The EventCatalog MCP server provides the following tools:

Tools

  • find_resource - Get detailed information about services, domains, events, commands, queries, or flows
  • find_producers_and_consumers - Get producers and consumers for a service
  • get_schema - Returns schema for services, events, commands, or queries
  • review_schema_changes - Reviews schema changes for breaking changes
  • explain_ubiquitous_language_terms - Explain domain-specific terminology
Resources
  • eventcatalog://all - All messages, domains and services
  • eventcatalog://events - All events
  • eventcatalog://domains - All domains
  • eventcatalog://services - All services
  • eventcatalog://queries - All queries
  • eventcatalog://commands - All commands
  • eventcatalog://flows - All flows
  • eventcatalog://teams - All teams
  • eventcatalog://users - All users

🔍 Learning Questions

Here are the key questions this project aims to explore:

Menu Publishing Events
  1. Is there an event when a new menu gets published?
  2. Which team owns that event?
  3. How can I subscribe to that event?
  4. What do I need to know in order to process that event?
  5. What other menu service related events exist?
Event Registration & Discovery
  1. I have my own service, how can I register a new event with the eventcatalog?
  2. Do I need to notify someone when I register the new event and how would they be able to subscribe to my event?
Architecture Insights
  1. Is there any information on our event driven architecture?
  2. Is there an event flow you could create that shows when a menu is being published and who are all the subscribers of that event?
Error Handling & Reliability
  1. What if an event fails to be delivered, how would a subscriber get to know about that situation?

🎓 Learning Objectives

Through this project, you'll learn:

  • How to configure MCP servers for EventCatalog integration
  • How to query event-driven architecture documentation programmatically
  • How to discover events, schemas, and relationships in your architecture
  • How to understand team ownership and responsibilities
  • How to identify event flows and dependencies
  • How to explore error handling and reliability patterns

📚 Resources

🔧 Troubleshooting

Common Issues
  1. License Key Issues: Ensure your EventCatalog Scale license key is valid and not expired
  2. Network Access: Verify you can access the EventCatalog instance from your network
  3. OAuth Issues: Make sure you're authenticated with Google OAuth for the EventCatalog instance
  4. MCP Server Not Loading: Restart Cursor after modifying .mcp.json
Debug Commands
# Test MCP server installation
npx -y @eventcatalog/mcp-server --help

# Verify EventCatalog accessibility
curl -I https://eventcatalog.compassdigital.org/

📝 Notes

  • This project is designed for learning and exploration
  • The EventCatalog instance is protected by Google OAuth
  • Requires EventCatalog Scale license for full functionality
  • MCP integration works with Claude, Cursor, Windsurf, and other MCP-compatible clients

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
