Domain FAQs

Question 1

What is Domain (domain-mcp-server) and what problem does it solve?

Accepted Answer

Domain is a Model Context Protocol (MCP) server that clones and analyzes your microservices (code + documentation) to extract business logic, APIs, and database models, storing them in PostgreSQL. It solves the challenge of scattered knowledge in complex microservice architectures by centralizing domain understanding.

Question 2

How does Domain leverage AI/LLMs for analysis?

Accepted Answer

Domain employs LLM-assisted extraction (compatible with Claude and similar APIs) to deeply analyze code and documentation. This allows it to identify, understand, and map complex business logic, domain concepts, APIs, and data models automatically.

Question 3

What kind of information does Domain extract and how is it accessed?

Accepted Answer

Domain extracts and catalogs services, domain concepts, APIs, and database models/entities. This structured information is stored in a PostgreSQL database and can be queried rapidly using the Model Context Protocol for semantic insights.

Question 4

How does Domain integrate with other developer tools or systems?

Accepted Answer

Domain is designed to operate both standalone and in conjunction with other MCP servers, such as Datadog MCP. This integration allows developers to combine runtime data (traces, logs) with comprehensive domain semantics for enhanced debugging, root-cause analysis, and cross-service reasoning.
