Frequently asked questions

An MCP memory server is a Model Context Protocol server that gives an AI assistant persistent memory. Instead of starting every session from zero, the assistant calls tools to save findings and search earlier ones. OttO stores that memory as a knowledge graph, so related notes, solutions and decisions are linked rather than kept as a flat list.

Install OttO Core, then add it to .mcp.json in your project (or ~/.claude/mcp.json globally) as an HTTP server at http://localhost:47821/mcp. Claude Code connects on the next session. The installer also registers a session hook in ~/.claude/settings.json that reminds Claude Code to use the OttO tools at the start of every session.

OttO works with any MCP client that supports the HTTP transport. Setup is documented for Claude Code, Cursor and Antigravity, and the OttO Desktop app and OttO Mobile app connect to the same graph.

Yes. OttO Core keeps the knowledge graph in a local vector database on your own machine; nothing is stored on OttO's servers. With Ollama for embeddings and chat, no text leaves your computer at all. If you choose OpenAI or Groq, the text being embedded or answered is sent to that provider using your own API key.

Embeddings can run locally through Ollama or through OpenAI. The built-in agent that answers questions from your graph can use Ollama, OpenAI or Groq, and you can switch providers in OttO Desktop under Settings → Provider.

OttO Core exposes 24 MCP tools. They cover adding knowledge, semantic and graph-spreading search, saving and searching inferences (solved problems), plans and decisions, reading attached PDF, Word and text files, and a task queue that agents and the mobile app share.

A vector database returns isolated chunks, and a notes app needs you to organize everything by hand. OttO classifies each note as you add it, links it to related nodes automatically, and searches along those links. It also records solutions, plans and decisions with their reasons, so an agent can recall why something was done, not just what was written.

OttO is free forever for personal use; you bring your own API keys, or use Ollama with no keys at all. Self-hosted team plans are billed annually: Team $2,000 (up to 10 seats), Business $4,500 (up to 25), Business+ $8,000 (up to 50) and Enterprise from $15,000 (100+ seats).

Yes. OttO Cloud, the multi-tenant edition of OttO Core, runs on your own servers and gives the whole organization one shared knowledge graph. Every write is attributed to the member who made it, roles control who can write or configure providers, and every client connects the same way a local install does.
