MindGraph Documentation
MindGraph is a cognitive OS for AI agents. Start with quick unstructured journal notes, then layer in structured knowledge through 18 cognitive endpoints that create typed nodes and edges automatically.
Keep the flexibility of unstructured data and the contextual power of a cognitive graph — one API for storage, reasoning, and retrieval.
Quickstart
Sign up, get an API key, and make your first call in under 5 minutes.
Agent Memory Patterns
How to read and write memory: journals, ingestion, retrieval, sessions, and the complete agent loop.
Agents
Autonomous research agents: templates, sessions, schedules, and the managed agent HTTP surface.
Projects & Synthesis
Scope a document corpus to a project, mine cross-document signals, and auto-generate synthesis articles.
Authentication
API key auth, JWT auth, and OAuth flows.
SDKs
TypeScript and Python clients for the MindGraph Cloud API.
API Reference
Full REST surface: CRUD, cognitive endpoints, synthesis, and managed agents.
Cognitive Endpoints
18 endpoints for structured knowledge: reasoning, planning, decisions, and more.
Concepts
Cognitive layers, node types, edge types, traversal, search, and more.
Architecture at a glance
Knowledge is organized into six cognitive layers that mirror how agents reason. Use journal entries for quick unstructured notes, or cognitive endpoints to create typed nodes (55 types) with automatic edges (77 types). Built-in full-text search, semantic vector search, BFS traversal, temporal decay, versioning, and multi-agent identity tracking.
