Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "engram": {
      "command": "npx",
      "args": [
        "-y",
        "engramx"
      ],
      "env": {
        "ENGRAM_API_TOKEN": "your-value",
        "ENGRAM_MISTAKE_GUARD": "your-value",
        "ENGRAM_ANTHROPIC_MEMORY_PATH": "your-value",
        "ENGRAM_MCP_CONFIG_PATH": "your-value",
        "ENGRAM_NO_UPDATE_CHECK": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add engram --env ENGRAM_API_TOKEN=your-value --env ENGRAM_MISTAKE_GUARD=your-value --env ENGRAM_ANTHROPIC_MEMORY_PATH=your-value --env ENGRAM_MCP_CONFIG_PATH=your-value --env ENGRAM_NO_UPDATE_CHECK=your-value -- npx -y engramx

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "engram": {
      "command": "npx",
      "args": [
        "-y",
        "engramx"
      ],
      "env": {
        "ENGRAM_API_TOKEN": "your-value",
        "ENGRAM_MISTAKE_GUARD": "your-value",
        "ENGRAM_ANTHROPIC_MEMORY_PATH": "your-value",
        "ENGRAM_MCP_CONFIG_PATH": "your-value",
        "ENGRAM_NO_UPDATE_CHECK": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "engram": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "engramx"
      ],
      "env": {
        "ENGRAM_API_TOKEN": "your-value",
        "ENGRAM_MISTAKE_GUARD": "your-value",
        "ENGRAM_ANTHROPIC_MEMORY_PATH": "your-value",
        "ENGRAM_MCP_CONFIG_PATH": "your-value",
        "ENGRAM_NO_UPDATE_CHECK": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

ENGRAM_API_TOKEN secret env
Optional HTTP bearer token. Auto-generated at ~/.engram/http-server.token if unset.
ENGRAM_MISTAKE_GUARD env
Pre-mortem warnings: '1' = warn, '2' = deny. Unset = off, zero overhead.
ENGRAM_ANTHROPIC_MEMORY_PATH env
Override path to Claude Code's Auto-Memory MEMORY.md.
ENGRAM_MCP_CONFIG_PATH env
Override path to ~/.engram/mcp-providers.json (plugin MCP server declarations).
ENGRAM_NO_UPDATE_CHECK env
Set to '1' to disable passive update notice. Auto-disabled when $CI is set.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Engram safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ENGRAM_API_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (4.5.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Engram

A local structural code graph and context toolkit for AI coding agents. Engram indexes source entities, Git relationships and selected project memory, then exposes focused context through a CLI, agent hooks, MCP and an authenticated local dashboard.

Use it to find relevant code before reading full files, inspect relationships and carry recorded mistakes into a later session. Read the source returned by a query before making a behavioral claim: graph retrieval is an aid to investigation.

Quickstart

The inspected package is engramx 4.5.0 and requires Node >=20. This source-build example is source-inspected, not executed; it does not assume a currently published package or extension version.

git clone https://github.com/NickCirv/engram.git

cd engram git checkout 9fa2a4b74ca8e66560d74d1255c16c43157d32bd npm install --ignore-scripts npm run build export ENGRAM_NO_UPDATE_CHECK=1 node dist/cli.js init ../your-project --no-hook node dist/cli.js query "authentication" --project ../your-project --budget 2000 node dist/cli.js stats --project ../your-project

Replace ../your-project with a codebase you can inspect. Indexing writes the project's .engram/ graph. The --no-hook flag matters: the default CLI init also installs a Sentinel hook. Start with the graph, examine the output, then decide which integration to enable. The build includes grammar bundling; inspect package scripts and dependencies before installation.

The query returns matching graph entities and an estimated token count, or a no-matching-nodes message. Counts depend on the indexed project; no benchmark output is fabricated here.

What is implemented

Workflow	Source-backed entry points
Explore structure	`query`, `path`, `gods`, `callers`, `callees`, `impact`, `stats`
Maintain context	`init`, `watch`, `reindex`, `learn`, `mistakes`
Generate agent documents	`gen`, `gen-mdc`, `gen-aider`, `gen-windsurfrules`, `gen-ccs`
Inspect hook integration	`install-hook --dry-run`, `hook-preview`, `hook-stats`, `hook-disable`, `hook-enable`
Serve context	`server`, `ui`, `engram-serve` MCP executable
Review measurements	`measure`, `bench`, `cost`, package benchmark scripts
Maintain installation	`doctor`, `setup --dry-run`, `update --check`, database/cache/plugin commands

These entry points are declared in the pinned CLI. Consult each command's help before a write operation. Generators, hook installers, cache/database commands and plugin installation can modify local state.

Architecture

Source miners extract entities, references, Git co-change and selected mistake/session information. The graph store persists project-local SQLite using sql.js. Queries traverse the graph and render bounded context. The provider resolver combines built-in sources and optional plugins/MCP providers; integrations can add external processes and network access.

The architecture and integration guide maps these paths, documents HTTP authentication and gives a local MCP configuration. Existing design records, release notes, integration documents and the ECP draft remain linked in the documentation inventory. They retain historical context and are not all certified against this revision.

Privacy and operational boundaries

The core graph is local, but the entire system is not guaranteed to be network-free. The CLI has npm update checks, Context7 can call an external wrapper, and configured MCP/plugin providers can execute their own processes. ENGRAM_NO_UPDATE_CHECK=1 disables the update-check path; it does not disable every optional integration. Review configured providers and the agent that receives graph output.

The HTTP server binds to 127.0.0.1, validates Host/Origin and requires a bearer token or dashboard cookie for protected routes. It resolves a token from ENGRAM_API_TOKEN or a local token file. Keep that token private and retain the existing security policy.

Limits and measurement

Structural context size, estimated token reductions, session replay and actual provider billing answer different questions. A smaller packet does not by itself demonstrate equal answer quality or a lower bill. Reproduce the included benchmarks on your own representative workload and track correctness alongside cost. This documentation review did not run a build, test suite, benchmark or agent session.

Development

npm run build

npm run lint npm test -- --run

The repository contains unit and integration test sources for graph storage, providers, hooks, HTTP security and other modules. Their presence is evidence of test coverage intent; results at this revision remain unverified here. See the preserved contribution guide before changing behavior.
