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.

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 | $0.00003 | $0.00159 |
| Opus 5 | $0.00002 | $0.00079 |
| Sonnet 5 | $0.00001 | $0.00032 |
| Haiku 4.5 | $0.00000 | $0.00016 |
Grade A, and why
maintenance 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 3d 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.
What it actually says
Perform database maintenance operations.
Subcommands:
- No args or
vacuum: Run basic maintenance (mcp__memory__db_maintenance) cleanup: Run comprehensive cleanup (mcp__memory__run_cleanup)validate: Check embedding model compatibility (mcp__memory__validate_embeddings)
db_maintenance performs:
- VACUUM to reclaim unused space
- ANALYZE to update query planner stats
- Auto-demote stale hot memories
run_cleanup additionally:
- Expires old mining patterns
- Deletes old output logs
- Applies type-specific retention policies
validate_embeddings checks if embedding model changed since database was created.
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.

maintenance is a command published in the GitHub repository michael-denyer/memory-mcp (7 stars, last pushed 15d ago), licensed MIT. It adds 3 tokens to every session and 159 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
