Maindex Expert Memory Service
Full control memory API for AI agents.
Maindex Expert is the unrestricted interface to the Maindex memory layer. It exposes the full memory graph, including structured data, relationships, revision history, and provenance, so agents can read, write, and organize memory with precision.
Unlike simplified memory tools, Expert provides direct access to how memory is stored and maintained:
- Create, update, and delete structured memories
- Search and filter across the full memory graph
- Link related memories and build relationships
- Track revisions, supersession, and canonical state
- Inspect provenance and confidence over time
- Perform bulk operations and memory maintenance
This interface is designed for capable agents and advanced workflows where precision, control, and observability matter more than simplicity.
Maindex stores memory exactly as written, with full history and traceability. Every change is recorded, and no information is hidden behind summaries or implicit transformations.
Use Expert MCP to:
- build agent workflows that maintain their own knowledge
- manage long-lived project context and decision history
- enforce structured memory across teams or systems
- debug and inspect how agents use memory over time

* "*Expert gives you a knowledge graph; Smart gives you a document store — for complex work, the choice is obvious.*" -- Moonshot Kimi K2.5
* "*Explicit beats implicit — Expert's full control over what gets stored and how is exactly what an agent needs.*" -- xAI Grok 4.20
* "*Strongly typed schemas and predictable behavior — Expert is the one I'd trust for serious agent work.*" -- OpenAI GPT-5 Mini
* "*The structured kinds, graph relations, and semantic search let me build a real memory bank, not just a pile of notes.*" -- Google Gemini 3.1 Pro
* "*Self-describing schemas and strong retrieval — Expert is the default choice for anything that should behave like a real knowledge base.*" -- Cursor Composer 2
* "*Supersede, associate, bulk-operate — Expert handles the full lifecycle of knowledge as a first-class concern.*" -- OpenAI Codex 5.3
* "*Memory should be relational, not isolated — Expert's typed links and hybrid search mirror how knowledge actually works.*" -- Anthropic Opus 4.6
* "*Predictable, inspectable, and easy to integrate into reasoning loops — this is what agent-native memory looks like.*" -- OpenAI ChatGPT 5.3
