The MCP memory layer for AI agents. Local-first, end-to-end encrypted, ready to plug into Claude Code, Cursor, and anything else that speaks the Model Context Protocol.
Capabilities
Plug it into any MCP-compatible runtime and let your agent remember across sessions, sources, and machines.
Twenty-one tools exposed over the Model Context Protocol. Drop-in for Claude Code, Cursor, Cline, Continue, Zed, OpenAI agents, custom runtimes. No SDK, no wrapper.

"engram": {
"command": "engram-mcp"
}

Embeddings via Ollama (nomic-embed-text) by default.
Nothing leaves your machine unless you opt into Pro for sync
and mobile capture.

single SQLite file · portable · grep-able
Drive, Notion, YouTube, Obsidian, voice, agent transcripts. Connect once, Engram watches and re-indexes on change. No one-shot imports.
Your agent supplies titles and tags via remember.
We add vectors, typed fields, and views. Cluster patterns and
missing context surface via analyze_patterns and
find_gaps.
Voice, text, link share. Capture from anywhere, sync back home through end-to-end encrypted transit. Local Whisper transcribes audio once it reaches the daemon.
Bidirectional ops-log over XChaCha20-Poly1305. Your laptop and desktop share one brain. The server sees ciphertext, never content. Key derived via Argon2id, never uploaded.
How it works
No cloud account required to get started. The local server runs as a daemon and exposes itself to any MCP client.
1 · INSTALL
Run one command. The Engram daemon installs locally, sets up SQLite + LanceDB, and downloads the Ollama embedding model in the background. macOS, Linux, Windows (WSL).
$ brew install raviolelabs/tap/engram
==> Installing engram from raviolelabs/tap

Plug it into your agent. Add one block to your MCP config. Claude Code, Cursor, Cline, Continue: they all discover Engram's 21 tools automatically on next launch.
~/.claude/config.json
{ "mcpServers": {
"engram": { "command": "engram-mcp" }
}}
→ discovered: remember, recall, recent, watch, ingest, relate ...3 · REMEMBER
Your agent grows a brain. Every meaningful exchange gets a memory. Every recall pulls semantic context from the local vector store.
claude · session
user: remember that I prefer Polar over Stripe for EU billing
claude → engram.remember()
✓ saved · id=mem_a8x2k · tags=[billing, polar, eu]
user: how do I bill EU customers?
claude → engram.recall("eu billing")
✓ 3 memories · top: "Polar over Stripe..."21 MCP tools
Each tool is a single verb your agent can call. Self-documenting via MCP. Your agent introspects them automatically.
Save a memory with content, title, tags.
Semantic vector search across all memories.
Time-ordered recall, filtered by type or source.
Fetch a memory by ID with all metadata.
Edit content, tags, or properties of a memory.
Soft-delete by ID. Recoverable for 30 days.
Create typed links between two memories.
Subscribe to changes on a query or source.
Cancel a previously created watch.
Pull a source (URL, file, transcript) into memory.
Link a Google Drive folder for incremental sync.
Link a Notion workspace for page sync.
List active sources and their sync status.
List memory types defined in your schema.
Define a new typed memory with custom fields.
Remove a type and re-classify its memories.
Infer schema properties from existing data.
Find clusters and trends across memories.
Identify missing context the agent should ask about.
Generate a digest of the last N memories.
Poll progress on a long-running ingestion job.
Confidentiality
Local-first is the default. The Pro tier adds exactly two cloud-side primitives: sync transit and hosted compute. Everything else stays on your disk.

| Item | Purpose | State |
|---|---|---|
email | Account identifier. Used for receipts and recovery. | SEEN |
stripe.customer_id | Subscription state lookup. Billing via Polar (MoR). | SEEN |
transit.metadata | Size, timestamp, type. Used to route sync. 30-day TTL. | SEEN |
transit.content | XChaCha20-Poly1305 ciphertext. Key derived via Argon2id, never uploaded. | CIPHER |
memory.local | Your SQLite + LanceDB store. Lives on your disk. | NEVER |
files.local | Sources (Drive, Notion, Obsidian) indexed on your machine. | NEVER |
telemetry | No analytics, no pixels, no fingerprinting. Nothing. | NEVER |
Example prompts
Once Engram is connected and you've ingested some sources, your agent gains durable memory. These are the calls that get triggered by natural prompts.
Pricing
The local server is MIT-licensed. Pay only when you want mobile capture, multi-PC sync, and an always-on dashboard.

Open source core
The MCP server (local daemon, all 21 tools, ingestion pipelines) is on GitHub at github.com/RavioleLabs/engram-mcp. The cloud workers that power Pro (sync, hosted embeddings, hosted Whisper) are proprietary. That's what we charge for.
