MCP-native memory for any agent

Memory for your AI agents. Kept by you.

Legate is memory as a service. One MCP endpoint gives Claude, your coding agent, and your own workers the same durable, searchable memory, stored as Markdown in a GitHub repo you own.

Why Legate

Agents forget between sessions. Legate doesn't.

Every framework ships its own memory that only it can read. Legate is one store behind a standard protocol, so context moves with the work instead of staying behind.

One memory, every agent

Hand a task from Claude to your coding agent to a background worker. They all read and write the same notes.

Recall that stays small

Keyword search returns short hits. Agents fetch only the notes they need, not 40 KB of context.

Safe with many writers

Appends are atomic and edits are diff-based, so parallel agents don't overwrite each other or your changes.

Plain Markdown you own

Notes are files in your GitHub repo with full history. Clone it, read it anywhere, and leave whenever you like.

How it works

Connect once. Remember everywhere.

Legate is MCP-first: the protocol is the product, and the web app is where you review what your agents know.

01

Add one MCP entry

Point your client at legate.studio/mcp and sign in with GitHub over OAuth. No API key to paste or rotate.
02

Agents write what they learn

Decisions, findings, and handoffs become notes. AI digestion titles them and files them by category, and agents link related notes.
03

Any session picks up the thread

Tomorrow, or in a different tool, an agent searches, reads the few notes it needs, and carries on.

Privacy

Private today. Unreadable to us next.

Now

Isolated and yours

Notes live in your private GitHub repository.
Each account gets its own isolated index database.
Your content is never used to train models.

Per-user encryption

Keys are derived from your passkey on your device.
Legate stores only wrapped keys, never the key itself.
Admins can't read your notes, even for support.
