Engram

Official registry Search and web

Persistent, verbatim, searchable memory for AI assistants — one memory across every MCP client.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)
Claude Code
claude mcp add --transport http engram 'https://mcp.getengram.app/mcp'
JSON configuration (Claude Desktop, Cursor, VS Code)
{
    "mcpServers": {
        "engram": {
            "type": "http",
            "url": "https://mcp.getengram.app/mcp"
        }

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@engram

Restart 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

Frequently asked questions

What is Engram?

Persistent, verbatim, searchable memory for AI assistants — one memory across every MCP client.

How do I install Engram?

It runs as a remote server. In Claude Code: claude mcp add --transport http engram 'https://mcp.getengram.app/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Engram need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is Engram open source?

Its code is public on GitHub, but the repository does not declare a standard license.

Who maintains Engram?

It is published by get-engram. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
