Phloem

Phloem is a local-first AI memory server that stores memories as causal graphs, running entirely offline on the user's machine with no configuration.

What you can do

Store and recall AI memories locally, organized as causal graphs rather than flat notes or embeddings. Keep memory data on the user's own machine, with no cloud dependency. Run without configuration, since no environment variables, headers or authentication are declared. Operate as a desktop-only local process over stdio.

When to use it

Useful when an assistant should remember context across sessions while keeping that data private and offline, or when you want memory relationships expressed as cause-and-effect links rather than simple retrieval.

Requirements

Runs as a local process on the user's machine over stdio, distributed as a macOS (darwin-arm64) MCP bundle. Desktop only; no web execution. No accounts, API keys, environment variables or headers are declared.
