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 | $0.00083 | $0.01232 |
| Opus 5 | $0.00042 | $0.00616 |
| Sonnet 5 | $0.00017 | $0.00246 |
| Haiku 4.5 | $0.00008 | $0.00123 |
Grade A, and why
ourgroceries-cli 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 10d 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.

OurGroceries CLI
Overview
Use the @sergib/ourgroceries-mcp CLI for OurGroceries operations. Prefer the CLI when the user
wants concrete list data, scriptable JSON output, or terminal-driven mutations.
Critical Rule: Never Permanently Remove Items
MANDATORY: Never call remove-item. Always use cross-off-item instead.
Whenever the user asks to remove, delete, eliminate, erase, take off, get rid of, drop, scratch,
take out, or any equivalent verb in any language (e.g. Spanish "quitar", "eliminar", "borrar",
"sacar"; Catalan "treure", "eliminar", "esborrar"; French "enlever", "supprimer"; German
"entfernen", "löschen"; etc.), treat the request as a cross-off and run cross-off-item.
This applies even when the user explicitly says "remove" or "delete" — the user's intent is to
clear the item from the active list, and crossing it off preserves history and OurGroceries'
learning behavior. Never use remove-item unless the user explicitly insists on permanent deletion
after being told that cross-off is the default and confirms they want destructive removal anyway.
Authentication
The CLI reads saved credentials first, then OURGROCERIES_AUTH_COOKIE and
OURGROCERIES_TEAM_ID.
If credentials are missing, tell the user to run:
npx -y @sergib/ourgroceries-mcp login
Do not ask the user for their OurGroceries password in chat. Do not pass passwords on the command
line. logout removes the saved config file and does not modify environment variables:
npx -y @sergib/ourgroceries-mcp logout
Read Workflow
Start with lists unless the user already gave a listId:
npx -y @sergib/ourgroceries-mcp get-lists
Use IDs from that output for focused reads:
npx -y @sergib/ourgroceries-mcp get-active-items --list-id LIST_ID
npx -y @sergib/ourgroceries-mcp get-crossed-off-items --list-id LIST_ID --search "milk" --limit 20
npx -y @sergib/ourgroceries-mcp get-categories
npx -y @sergib/ourgroceries-mcp get-settings
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.
