PMB (Personal Memory Brain)

by oleksiijko

Stop re-explaining last week's decisions — your agent reads them back from a local memory you own.

Agent Memory
Summary
Reading is automatic and cheap — no LLM call sits on the recall path.

Lifecycle hooks call prepare and recall when memory is relevant, so you rarely invoke anything by hand, and because recall does not go through a model it stays fast enough to run constantly. The lesson loop is the unusual bit: surfaced lessons carry an id, and marking whether one actually changed behaviour is what feeds the self-improvement side rather than a claimed percentage.

What it is

A local-first memory workspace for MCP-aware coding agents. SQLite is the source of truth; search indexes sit beside it and are rebuildable.

What you get
  • prepare — one call at the start of a task returning project context, surfaced lessons, recent activity and open goals; session_brief re-orients you mid-session
  • recall, recall_smart and recall_deep — search memory, escalating to a deeper search only when confidence is low
  • overview and project_overview — a structured what-do-I-know about a topic or a project, from the entity graph
  • find_lessons and mark_lesson_followed — procedural rules with a surface_id, and a report of whether one actually changed behaviour
  • record_batch as the single write path, plus record_fact, record_fact_tree, record_keyed_fact, record_goal, update_goal, record_activity, record_milestone, pin and forget
  • index_pdf, index_project, record_code and record_image for pulling material in
  • Tool profiles so the agent is not overwhelmed: minimal at 10 tools by default, lean at 30, default at 34, full at around 65
  • graph_stats, graph_top_entities and graph_neighbors for inspecting the entity graph
Requirements

Pip install pmb-ai, then pmb setup to detect your agent and write the MCP entry, pmb warmup to preload the model, and a client restart. pmb doctor confirms the wiring. The CLI is pmb, with pmb-ai as an alias; an npm path exists too. No account, no API keys, and no LLM call on the read path — everything stays on your machine. PMB_TOOL_PROFILE picks the tool profile.

Setup effort

One command — pip install pmb-ai && pmb setup
