mcp-memory-graph: Skill for Claude Code

.claude/skills/mcp-memory/SKILL.md

mcp-memory is a skill for Claude Code from YonasValentin/mcp-memory-graph. It costs 242 tokens per session (1,666 once invoked), scanned A, original, no licence file.

A local memory system for coding agents that stores information as connected facts over time in one SQLite database, a file-based database. It includes tools and local text embeddings, which help relate similar pieces of information, without cloud storage or telemetry.

In plain words
What is it for?
Use it to operate or develop the mcp-memory-graph server and manage long-term, time-aware knowledge about projects.
Why use it?
It gives an agent project memory that can remain on the local machine instead of being scattered across conversations or sent to a cloud service.

Skill for Claude Code

This is YonasValentin/mcp-memory-graph's own configuration. It tells Claude Code how to work on mcp-memory-graph itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-memory-graph configures →

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

mcp-memory 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
