state-memory-mcp

Rules for tracking project sessions, tasks, decisions, dependencies, and blockers in a shared project graph.

In plain words
What is it for?
Use them before and during coding to start sessions, find runnable tasks and blockers, trace dependencies, and record work or decisions.
Why use it?
They provide a consistent record of what work is active, what decisions were made, and what is preventing progress.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

state-memory-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

98% identical to state-memory-mcp — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

State Memory (state-memory-mcp)

This project tracks workflow state, tasks, design decisions, and blockers using state-memory-mcp with project slug "spc".

1. Priority Order

Before doing any coding or investigation:

  1. manage_sessions(action: "start") — Start a tracking session for full change attribution.
  2. get_analytics(action: "summary") — Run to understand current project state, active branches, and overall progress.
  3. manage_tasks(action: "next") — Query prioritized runnable tasks.
  4. manage_tasks(action: "find_blockers") — Identify any active blockers preventing progress.
  5. manage_nodes(action: "list") — Find pending tasks, past decisions, or milestones.
  6. query_graph(action: "trace") — Trace what depends on or blocks a task.

2. When to Write to the Graph

You MUST update the graph as you work:

  • Starting a session: Always call manage_sessions(action: "start", agent_id: "my-agent") to track all mutations under a unique session.
  • Starting a new task: Create a node with manage_nodes(action: "create", type: "task", title: "...", session_id: session_id).
  • Making a design or implementation decision: Document it with manage_nodes(action: "create", type: "decision", title: "...", metadata: { "rationale": "..." }, session_id: session_id).
  • Encountering a blocker: Record the blocker with manage_nodes(action: "create", type: "blocker", title: "...", session_id: session_id) and connect it using manage_edges(action: "add", type: "blocks", source_id: blocker_id, target_id: task_id, session_id: session_id).
  • Adding observation notes: Atomically log notes using manage_nodes(action: "add_note", text: "...", attach_to: node_id).
  • Batch updates: Bulk update tasks/nodes using manage_nodes(action: "batch_update", ids: ["..."], status: "done").
  • Completing a task: Update status to done using manage_tasks(action: "complete", task_id: task_id) or manage_nodes(action: "update", id: task_id, status: "done").
  • Creating/generating a new file: Create an artifact node with manage_nodes(action: "create", type: "artifact", title: "...", session_id: session_id) and connect it using manage_edges(action: "add", type: "produces", source_id: task_id, target_id: artifact_id).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

state-memory-mcp is a cursor rule published in the GitHub repository putervision/spc (44 stars, last pushed 11d ago), licensed MIT. It adds 881 tokens to every session, about $0.0044 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to state-memory-mcp, differing in 2 lines, and is treated as a copy.
