About Echo Memory
Echo Memory is an MCP server published by echo-mem.com. Shared memory for AI agents, as a graph in your own Postgres. Writes never call an LLM.
It runs on your own machine: your AI client starts it from the PyPI package echo-mem at version 0.5.6, or you can connect to the hosted version instead.
It asks for one secret: ECHO_MEMORY_DATABASE_URL. Give it a key with the least access that still works.
It also needs ECHO_MEMORY_USER_ID and ECHO_MEMORY_AGENT_ID set before it starts.
Version 0.5.6 was published on 27 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 10 automated checks on the registry entry and the package code: 8 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
ECHO_MEMORY_DATABASE_URL | Yes | Yes | Postgres connection string. `echo-memory quickstart` starts a suitable database and prints this. |
ECHO_MEMORY_USER_ID | Yes | No | Whose memory this is. Scopes every read and write. |
ECHO_MEMORY_AGENT_ID | Yes | No | Which tool is writing: claude-code, cursor, codex, claude-desktop. Recorded on every fact, and what makes a cross-tool recall visible afterwards. |
