What is memory-mcp CLAUDE.md?

Project instructions and memory notes for the memory-mcp system, including its design, decisions, pitfalls, and current progress. It uses CLAUDE.md and a separate state file to retain context across coding sessions.

Use it when setting up, searching, consolidating, or checking the status of project memory, or when continuing work on a large project.

It helps an agent recover project context and find deeper information without relying on a small conversation window. It also records decisions and known setup problems in one place.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00866	$0.00866
Opus 5.5	$0.00346	$0.00346
Sonnet 5.5	$0.00173	$0.00173
Haiku 4.5	$0.00087	$0.00087

Security

Grade A, and why

memory-mcp CLAUDE.md 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 2mo 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.
