store

store is a skill for Claude Code from mem9-ai/mem9. It costs 20 tokens per session (512 once invoked), scanned A, original, Apache-2.0.

A memory-saving skill for Mem9, an AI-agent memory service. It is used when a user explicitly asks the agent to remember one fact, preference, or instruction.

In plain words
What is it for?
Extracting one item the user wants remembered and storing it in Mem9, or reporting that setup is needed before it can be saved.
Why use it?
It gives the agent a defined way to save a single requested memory while keeping connection credentials private. Mem9 must already be configured.

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions .claude-plugin.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

About the project

mem9 is a persistent memory service for AI agents that preserves information across sessions and machines and can share it among multiple agents. It is used with OpenClaw, coding agents, workflow platforms, and custom clients that need shared storage and recall. The catalogue add-ons connect agents and workflows to mem9 memory.

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

store scanned grade A with 1 finding 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 1mo 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.

What it actually says

Mem9 Store

Use this skill only when the user explicitly asks Claude to remember or save something to Mem9.

Steps

  1. Extract the one fact, preference, or instruction that should be remembered.
  2. Use ${CLAUDE_PLUGIN_DATA}/auth.json only as request credentials. If auth is missing, tell the user to run /mem9:setup. Do not print the file contents or the API key.
  3. Store the memory with the single-message content API. Do not invent tags client-side.
set -euo pipefail

auth_file="${CLAUDE_PLUGIN_DATA}/auth.json"
test -f "$auth_file"
read_api_key_and_base_url="$(node -e 'const fs=require("node:fs"); const data=JSON.parse(fs.readFileSync(process.argv[1],"utf8")); const values=[data.api_key || "", data.base_url || "https://api.mem9.ai"]; process.stdout.write(values.join("\t"));' "$auth_file")"
api_key="${read_api_key_and_base_url%%	*}"
base_url="${read_api_key_and_base_url#*	}"
test -n "$api_key"
test -n "$base_url"
plugin_version="unknown"
if [ -n "${CLAUDE_PLUGIN_ROOT:-}" ] && [ -f "${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json" ]; then
  plugin_version="$(node -e 'const fs=require("node:fs"); const data=JSON.parse(fs.readFileSync(process.argv[1],"utf8")); process.stdout.write(data.version || "unknown");' "${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json")"
fi

curl -sf --max-time 8 \
  -H "Content-Type: application/json" \
  -H "X-API-Key: ${api_key}" \
  -H "X-Mnemo-Agent-Id: claude-code" \
  -H "User-Agent: mem9-plugin/claude-code/${plugin_version}" \
  -d '{"content":"REPLACE_WITH_MEMORY"}' \
  "${base_url%/}/v1alpha2/mem9s/memories"

Confirm back to the user what was saved. Never reveal secret values.

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.
