Phloem
Give coding agents persistent local memory with causal graphs without sending context to a cloud vector DB.
Overview
Phloem MCP is an MCP server for the Build phase that provides offline local-first agent memory using causal graphs.
What is this MCP server?
- 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
- Version 0.1.8; registryType mcpb
- Published binary: phloem-darwin-arm64.mcpb (GitHub releases)
- Transport: stdio; offline local-first design per description
What problem does it solve?
Cloud memory SaaS forces context off-device and adds setup friction for solo agent projects.
Who is it for?
Privacy-first builders on supported platforms who want offline agent memory without managing Pinecone or similar.
Skip if: Teams needing multi-user cloud sync, unsupported OS/arch binaries, or battle-tested enterprise memory SLAs.
What do I get? / Deliverables
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

Journey fit
Agent memory infrastructure is built while you assemble tooling stacks, before you rely on it in production operate loops. Agent-tooling subphase covers MCP memory layers, context graphs, and offline persistence for long-horizon agents.
How it compares
Local causal-graph memory MCP, not a hosted RAG pipeline or generic note-taking skill.
Common Questions / FAQ
Who is phloem for?
Solo 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.
