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 5.1 | $0.00075 | $0.00767 |
| Opus 5 | $0.00037 | $0.00383 |
| Sonnet 5 | $0.00015 | $0.00153 |
| Haiku 4.5 | $0.00007 | $0.00077 |
Grade A, and why
memory-guide 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
demo-mcp — shared memory guide
Remote private memory for Claude. MCP tools = capability. This skill = savoir-faire.
Product rules
| Rule | Detail |
|---|---|
| Auth | Every MCP call needs the plugin API key (userConfig.api_key) |
| Notes only | Markdown with OKF YAML frontmatter; type is required |
| Links | HTTP(S) URL ± optional human summary |
| Summaries | Never auto-generate link summaries. Only store what a human wrote. If missing → list needs_summary and invite contribution |
| Rate limit | 3 adds / min and 3 mods / min per IP — batch carefully |
| Surfaces | Same brain as https://demo-mcp.roxabi.dev (web) |
OKF note shape

## Body
Free markdown. Optional [[wikilinks]] or relative `[x](./other-id.md)` to link notes.
OKF fields: type (required), title, description, resource, tags, timestamp.
MCP tools (use these, not invent REST)
| Tool | When |
|---|---|
memory_search |
Default for “find / recall / what do we know about X” |
memory_list_notes / memory_get_note |
Browse or open one note |
memory_add_note / memory_update_note |
Write OKF markdown only |
memory_link_notes |
Explicit edge between two note ids |
memory_add_link |
Share URL; summary only if user provided it |
memory_list_links |
Especially needs_summary=true for contribution queue |
memory_contribute_summary |
Human summary for a link that has none |
memory_list_tags |
Taxonomy overview |
Decision tree
User wants context / recall → memory_search (then get_note if needed)
User wants to save prose/knowledge → memory_add_note (OKF template)
User pastes a URL → memory_add_link (summary only if they wrote one)
User wants to help fill gaps → memory_list_links needs_summary=true
User asks “how does this work” → explain this guide + web URL
401 unauthorized → ask user to re-enable plugin / set API key
429 rate_limit → wait Retry-After; do not spam retries
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.

memory-guide is a skill published in the GitHub repository MickaelV0/demo-mcp (0 stars, last pushed 1mo ago), licensed MIT. It adds 75 tokens to every session and 767 once invoked, about $0.0004 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 2026-09-01.
