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 | $0.00158 | $0.07809 |
| Opus 5 | $0.00079 | $0.03904 |
| Sonnet 5 | $0.00032 | $0.01562 |
| Haiku 4.5 | $0.00016 | $0.00781 |
Grade A, and why
iwac-mcp 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 6d 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 — 251 lines — stays where its author put it; the contents beside it link to each section on GitHub.
IWAC MCP Research Workflow
Structured methodology for academic research using the IWAC MCP server's 37 possible tools (34 core + 3 optional semantic). Adapted from ALA-compliant archival research practices. Applies to server v0.9.0+ — all matching is accent- and case-insensitive; result objects use short English keys (id, date, polarity, centrality, subjectivity, description_ai, url); list/search tools return a pagination envelope (count, total_matches, offset, limit, has_more, next_offset); and enumerated filters are validated (see Reading Results & Errors below). The essentials of this guidance are mirrored in the server's MCP instructions string (mcpb/src/index.ts) for skill-less clients — when updating one, update the other.
Prerequisites
Load reference files as needed, not all upfront:
- references/tools-by-phase.md — all 37 possible tools with parameters, defaults, and verified filter vocabularies. Read before the first search of a session.
- references/research-domains.md — French search terms and transliteration variants by domain. Read when crafting search-term variants (Extended mode, or when a Brief search comes back thin).
- references/biases-and-limitations.md — collection biases, coverage gaps, sentiment caveats. Read before writing the synthesis.
- references/capabilities-overview.md — plain-language description of the collection and recommended ways into the data. Read when the user asks what you can do (see "Capability Questions" below).
For data schema and Omeka S API details, defer to the iwac-data skill.
Capability Questions
When the user asks what you can do with IWAC ("what can you do?", "qu'est-ce que tu peux faire ?", "what's in this collection?", "how could I search this?"), do not launch the research workflow, present the depth choice, or enumerate the 37 tools. Read references/capabilities-overview.md and answer in plain language, in the user's language:
What ships with it
4 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.
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.

iwac-mcp is a skill published in the GitHub repository fmadore/iwac-mcp-server (2 stars, last pushed yesterday), licensed MIT. It adds 158 tokens to every session and 7,809 once invoked, about $0.0008 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.
