Persistent memory for AI agents. Infinite context with sub-millisecond recall.
Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON â–¾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for GrantAi Memory, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Documentation Overview
GrantAi
Deterministic Memory for AI
Local. Private. Secure.
Website • Download • Documentation
Free Edition — one command, no account
The free edition is the full local memory engine as an MCP server: no email, no license key, no trial, and no network after the one-time model download (about 650 MB).
The installer verifies both downloads against a published SHA-256 manifest, installs under ~/.grantai/free (Windows: %LOCALAPPDATA%\GrantAi\free), and registers the server with Claude Code, Claude Desktop, Cursor, Gemini CLI and Codex where they are installed. Any other MCP client takes the same command and arguments. Homebrew: brew install solonai/grantai/grantai-free. Air-gapped installs and the full list of what runs where are on the developers page.
The Problem
Every AI system today has the same flaw: it guesses instead of remembers.
RAG (Retrieval-Augmented Generation) converts your documents into vectors — numerical approximations of meaning. When you query, it returns content that is mathematically similar to your question. Similar is not the same as correct.
Ask for "HIPAA encryption penalties" and RAG returns chunks that look like compliance content. Maybe the right section. Maybe adjacent paragraphs. Maybe hallucinated ranges. You pay for every token retrieved, whether relevant or not.
This is the Retrieval Tax:
- Re-retrieval — Same questions, same searches, same cost
- Over-retrieval — 20 chunks when you need 3
- Labor — Engineers tuning embeddings instead of building products
- Risk — Approximate answers in domains that require precision
Enterprise AI spends 85% of compute on inference. Most of that is wasted on retrieving content that doesn't answer the question.
The Solution
GrantAi is deterministic memory for AI agents.
Instead of similarity search, GrantAi uses direct addressing. Every piece of knowledge has a unique identifier. Retrieval is a lookup, not a search. You get the exact content you indexed — verbatim, with attribution, in milliseconds.
| RAG | GrantAi |
|---|---|
| Returns similar content | Returns the exact content |
| 10-20 chunks, hope one is right | 1-3 sentences, always right |
| Slows down as corpus grows | Milliseconds regardless of size |
| No attribution | Full audit trail |
| Approximate | Deterministic |
Result: 97% reduction in tokens sent to the LLM. Faster responses. Lower cost. No hallucination from retrieval.
Why It Matters
- Compliance — Exact citations, not paraphrased guesses
- Multi-Agent — Shared memory across your AI workforce with speaker attribution
- Cost — Pay for answers, not for searching
- Security — 100% local, AES-256 encrypted, zero data egress

Multi-Agent Memory Sharing
Multiple agents can share knowledge through GrantAi's memory layer.
Basic shared memory (no setup required)
All agents read from and write to the same memory pool. No configuration needed.
With agent attribution (optional)
Use speaker to track which agent stored what, and from_agents to filter retrieval:
When to use speaker
| Scenario | Use speaker? | Why |
|---|---|---|
| Shared knowledge base | No | All contributions equal, no filtering needed |
| Session continuity | No | Same context, just persist and retrieve |
| Research → Code handoff | Yes | Coder filters for researcher's findings only |
| Role-based trust | Yes | Security agent's input treated differently |
Framework integration
GrantAi works with any MCP-compatible client. Point your agents at the same GrantAi instance:
All agents using this config share the same memory volume (grantai-data).
