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 | $0.00066 | $0.00598 |
| Opus 5 | $0.00033 | $0.00299 |
| Sonnet 5 | $0.00013 | $0.00120 |
| Haiku 4.5 | $0.00007 | $0.00060 |
Grade A, and why
tuma250 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.
What it actually says
Tuma250
Operate the Tuma250 grocery site, also called simply "Tuma", using the local tuma250 MCP server via mcporter.
Quick start (the 90% flow)
- Search
mcporter call tuma250.search_products query='eggplant' max_results=5
- If the product has sizes/variants, list them
mcporter call tuma250.get_product_variations product_url='https://tuma250.com/product/.../'
- Add to cart
- Simple product (slug from search_products or get_order_details):
mcporter call tuma250.add_to_cart --args '{"product_slug":"fresh-carrots-1kg","quantity":1}'
- Variable product (pass variation_attributes to pre-select variant):
mcporter call tuma250.add_to_cart --args '{"product_slug":"fresh-carrots-1kg","quantity":1,"variation_attributes":{"attribute_quantity":"500g"}}'
- View cart (basket)
mcporter call tuma250.get_cart --output json
Common tasks
Add an item (by name)
- Search with a good query (include brand/size if you can).
- If needed, select a variation.
- Add to cart.
Notes:
- Use
product_slug(e.g. from search result or get_order_details item). The slug is the last path segment of the product URL.
Confirm what’s currently in the basket
mcporter call tuma250.get_cart --output json
Return shape includes:
items[](name, qty, price, subtotal)shipping_options[]subtotal,total
Review recent orders
mcporter call tuma250.list_recent_orders limit=10
Get details for one order
mcporter call tuma250.get_order_details order_id='<id>'
Authentication
Usually you don’t need to do anything: tools auto-login as needed.
If you want to force it:
mcporter call tuma250.login()
Troubleshooting
If mcporter is not installed
It can be invoked via npx using npx mcporter
If the tuma250-mcp MCP server is not defined in mcporter configuration
It can be defined inline in the mcporter CLI using e.g. mcporter call --stdio "uvx tuma250-mcp" get_cart
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.
