Introduction

Compass is a context engine that builds a temporal knowledge graph of your organization — entities, relationships, and documents across every system — queryable by humans and AI agents alike. Search it. Traverse it. Reason over it.

The Problem

Organizations build complex systems — hundreds of services, pipelines, models, devices, and operations — all deeply interdependent. The knowledge about how these things connect, why they exist, and what depends on what lives in people's heads, scattered docs, and tribal memory.

Every day, engineers waste hours assembling context manually. AI agents hallucinate because they have no grounded knowledge to reason over. Changes break things nobody predicted. The missing layer is context.

Compass is that layer. It takes raw observations from collection systems like Meteor, resolves them into unified entities, builds a temporal graph of their relationships, and makes everything searchable and traversable — by humans and agents.

Key Features

  • AI-Native -- Composable MCP tools let AI agents search, traverse, assess impact, and read documents. Works with any MCP-compatible client.
  • Knowledge Graph -- Typed, directed, temporal relationships between entities including lineage, ownership, documentation, and custom edge types.
  • Context Assembly -- Multi-hop bidirectional traversal builds a subgraph around any entity — the full picture in one call.
  • Impact Analysis -- Blast radius analysis traces what depends on what and what breaks when something changes.
  • Hybrid Search -- Keyword precision combined with semantic similarity using Postgres-native full-text search and pgvector embeddings.
  • Documents -- Attach any document to entities — runbooks, decisions, postmortems, design docs — all indexed for semantic search.
  • Open Type System -- Any entity type, any edge type, any properties. Hardware, software, operations, people — anything fits.

Interfaces

  • CLI -- Manage entities, search, and run the server from the command line. See CLI.
  • API -- HTTP and gRPC via Connect RPC for programmatic access. See API.
  • MCP -- AI agents connect to the /mcp endpoint for tool-based access. See MCP.
