Engram runs on your own machine — the client starts it, so there is no endpoint to ping. 118 installs a week from npm. Last commit 22 Jun 2026.
Ranked local code-graph context for AI coding agents. Intercepts reads + greps. Apache-2.0.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

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