Phloem MCP is an MCP server that provides offline local-first agent memory using causal graphs.
About
Phloem MCP is a local-first memory server that stores agent context as causal graphs so Claude Code and similar hosts can recall relationships across sessions without a hosted vector database. developers in Build › Agent-tooling install the mcpb release for stdio transport when they need offline, zero-config persistence and strict data locality. Version 0.1.8 distributes a platform-specific MCP bundle from GitHub releases rather than npm, which matters for Apple Silicon Mac workflows called out in the registry entry. It complements cloud RAG stacks: you trade managed search scale for on-machine graph memory. Early 0.1.x maturity implies you should validate backup and corruption recovery before trusting sole production memory.
- Local-first AI memory with causal graphs (v0.1.8)
- Fully offline operation; zero config positioning; data stays on device
- Shipped as mcpb binary (darwin-arm64) with stdio transport
- Suited for privacy-sensitive solo builders avoiding cloud memory vendors

What it does
Give coding agents persistent local memory with causal graphs without sending context to a cloud vector DB.
Who is it for?
Privacy-first developers on supported platforms who want offline agent memory without managing Pinecone or similar.
Skip if: Skip if you need multi-user cloud sync, unsupported OS/arch binaries, or battle-tested enterprise memory SLAs.
What you get
After install, agents can read and write local causal-graph memory via MCP with data remaining on your machine.
- Running Phloem stdio MCP memory backend
- On-device causal graph memory accessible to agent tool calls
By the numbers
- Version 0.1.8; registryType mcpb

FAQ
Who is phloem for?
Developers building long-running coding agents who want local, offline memory with causal structure.
When should I use phloem?
Use it during Build when you wire MCP tooling and need persistent session memory before shipping customer-facing features.
How do I add phloem to my agent?
Register the mcpb stdio release (e.g. v0.1.8 phloem-darwin-arm64.mcpb from GitHub) in your MCP client config and point transport to the binary.
