Context for AI engineering
Give your AI assistants and agents the architectural context they need.
Domains, services, events, and schemas—straight from your living catalog.
AI assistants are only as good as the context you give them. A copilot that doesn't know your domain boundaries, your event schemas, or who owns what will hallucinate, suggest the wrong service, or invent fields that don't exist.
EventCatalog gives your AI tooling a structured, machine-readable view of your architecture: domains, services, events, schemas, ownership, dependencies, and the business context behind them—so the model is reasoning about your system, not a generic one.
Connect via the MCP server, the SDK, or direct API access—and let your assistants, agents, and internal tooling pull live architectural context whenever they need it.
Built for humans and machines
The same catalog that helps engineers onboard also gives copilots, agents, and AI assistants the grounded context they need to be genuinely useful.
Why grounded context matters
AI without architectural context vs AI with EventCatalog
The difference between a hallucinating copilot and a useful one is whether it actually understands your architecture.
Generic, guessy, often wrong
- Invents service names, fields, and event types that don't exist.
- Doesn't know domain boundaries, so suggestions cross teams and ownership.
- No awareness of consumers, so it can't reason about breaking changes.
- Hallucinates business workflows because it has nothing to ground them in.
Grounded, accurate, useful
- Reasons against real services, events, and schemas from your catalog.
- Understands domains, ownership, and how teams map to bounded contexts.
- Can identify producers and consumers before suggesting a schema change.
- Speaks your team's ubiquitous language because it's right there in the catalog.
How it works
Build your catalog
Document services, events, schemas, domains, and ownership in EventCatalog—manually, automatically, or both.
Expose via MCP
Run the EventCatalog MCP server so any MCP-aware AI client can query your architecture in real time.
Plug into agents
Use the SDK, REST APIs, or MCP to give copilots, internal agents, and IDE assistants the same architectural ground truth.
Stay grounded as you change
As your architecture evolves, the catalog evolves with it—and your AI tooling inherits the latest context automatically.
Use it for
Real workflows where grounded architectural context unlocks better AI engineering.
Copilots that know your system
IDE assistants and chat copilots that recommend the right service, schema, or event because they're querying your catalog—not guessing.
Internal agents and assistants
Onboarding bots, architecture Q&A, and operational agents that answer "who owns this?" or "who consumes this event?" instantly.
Safer change with AI review
Let AI reason about producers, consumers, and dependencies in your catalog before approving a schema change or deprecation.
