Echo Memory

com.echo-mem/echo-mem

Shared memory for AI agents, as a graph in your own Postgres. Writes never call an LLM.

Version: 0.5.7
Runs: Hosted or local
Packages: pypi
Published: Nov 7, 2026

Get started

Add it to your agent

claude mcp add echo-memory -e ECHO_MEMORY_DATABASE_URL=… -e ECHO_MEMORY_USER_ID=… -e ECHO_MEMORY_AGENT_ID=… -- uvx echo-mem==0.5.7

Run in your terminal. Add --scope project to share it with your team through .mcp.json.

codex mcp add echo-memory --env ECHO_MEMORY_DATABASE_URL=… --env ECHO_MEMORY_USER_ID=… --env ECHO_MEMORY_AGENT_ID=… -- uvx echo-mem==0.5.7

Saved to ~/.codex/config.toml.

{
  "mcpServers": {
    "echo-memory": {
      "command": "uvx",
      "args": [
        "echo-mem==0.5.7"
      ],
      "env": {
        "ECHO_MEMORY_DATABASE_URL": "…",
        "ECHO_MEMORY_USER_ID": "…",
        "ECHO_MEMORY_AGENT_ID": "…"
      }
    }
  }
}

Add to ~/.cursor/mcp.json (or .cursor/mcp.json in a project).

{
  "servers": {
    "echo-memory": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "echo-mem==0.5.7"
      ],
      "env": {
        "ECHO_MEMORY_DATABASE_URL": "…",
        "ECHO_MEMORY_USER_ID": "…",
        "ECHO_MEMORY_AGENT_ID": "…"
      }
    }
  }
}

Add to .vscode/mcp.json, then start it from the MCP view in Copilot Chat.

gemini mcp add echo-memory uvx echo-mem==0.5.7

Saved to .gemini/settings.json.

claude mcp add --transport http echo-memory https://api.echo-mem.com/mcp

The project also runs a hosted endpoint, so you can skip the local install.
