How do I install the octobrain mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `VOYAGE_API_KEY`, `OPENAI_API_KEY`, `GOOGLE_API_KEY`, `JINA_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Octobrain MCP Server?

Persistent memory for AI assistants with semantic search and knowledge graph relationships.

What it actually does

AI assistants start every conversation with zero context. You explain your project, your preferences, your decisions — every single time. Octobrain breaks that cycle:

Persistent memory — — Insights survive across sessions, not just within them
Semantic search — — Find memories by meaning, not exact keywords
Auto-linking — — Related memories connect automatically (Zettelkasten-style)
Knowledge indexing — — Ingest docs, articles, and files for retrieval
MCP integration — — Works with Claude Desktop and other MCP-compatible tools

memorize	Store memories with metadata; optional related_to for inline relationships
remember	Semantic search with filters; returns 1-hop graph neighbors
forget	Delete memories (requires confirmation)
knowledge	Unified tool: search, store, delete, read, match via command field
