Engram
Persistent, verbatim, searchable memory for AI assistants — one memory across every MCP client.
Installation
Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).
claude mcp add --transport http engram 'https://mcp.getengram.app/mcp'{
"mcpServers": {
"engram": {
"type": "http",
"url": "https://mcp.getengram.app/mcp"
}
}

Sommaire
Engram
Memory infrastructure for AI agents. Store every conversation verbatim. Search by meaning.
Engram is an MCP-native memory server that stores complete, uncompressed conversation transcripts and makes them searchable via semantic search. Connect any MCP-compatible client — Claude Desktop, Claude Code, Cursor, Windsurf, Zed — and your agent remembers everything across sessions.
Quick start
Claude Code
/plugin marketplace add get-engram/engram
/plugin install engram@engramRestart Claude Code and approve access in the browser. There is no API key to copy and no config file to edit — the server implements the MCP authorization flow (RFC 9728 / 8414 / 7591, PKCE), so the client discovers it, registers itself, and signs you in. A free account is created as part of signing in.
The plugin also ships a skill that tells Claude when to search memory and what is worth saving, so context accumulates without being asked.
Any other MCP client
Point it at the remote server and let OAuth handle access:
{
"mcpServers": {
"engram": {
"type": "http",
"url": "https://mcp.getengram.app/mcp"
}
}
}For a client that only speaks stdio, bridge to the remote server with mcp-remote — it drives the same browser OAuth flow, so there is still no key to copy:
{
"mcpServers": {
"engram": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://mcp.getengram.app/mcp"]
}
}
}(An older version of this README suggested npx @getengram/cli mcp; the CLI
has no such command and that configuration never worked.)
How it works
- Verbatim storage — every message stored exactly as sent, no summarization or compression
- Semantic search — find relevant context by meaning using bge-base-en-v1.5 embeddings
- MCP-native — speaks the Model Context Protocol natively, works with any compatible client
- Multi-tenant — per-organization isolation, team seats, and API key management
Architecture
Runs entirely on Cloudflare's developer platform:
- Workers — Hono.js API and MCP server
- D1 — SQLite at the edge for messages and metadata
- Vectorize — semantic search index
- Workers AI — embedding generation

Questions fréquentes
Qu'est-ce que Engram ?
Persistent, verbatim, searchable memory for AI assistants — one memory across every MCP client.
Comment installer Engram ?
Il fonctionne comme serveur distant. Dans Claude Code : claude mcp add --transport http engram 'https://mcp.getengram.app/mcp'. Pour les autres clients, collez la configuration JSON de cette page dans leurs réglages MCP.
Faut-il une clé API pour Engram ?
Son entrée au registre n'indique aucune clé ni secret obligatoire. Certaines fonctions peuvent tout de même demander un compte auprès du service auquel il se connecte.
Engram est-il open source ?
Son code est public sur GitHub, mais le dépôt ne déclare pas de licence standard.
Qui maintient Engram ?
Il est publié par get-engram. AI.tn le référence sans le maintenir ni le recommander.
Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
