Token cost

What it costs to keep this loaded

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.

Security

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 1mo 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.

Tuma250

Operate the Tuma250 grocery site, also called simply "Tuma", using the local tuma250 MCP server via mcporter.

Quick start (the 90% flow)

  1. Search
  • mcporter call tuma250.search_products query='eggplant' max_results=5
  1. If the product has sizes/variants, list them
  • mcporter call tuma250.get_product_variations product_url='https://tuma250.com/product/.../'
  1. 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"}}'
  1. View cart (basket)
  • mcporter call tuma250.get_cart --output json

Common tasks

Add an item (by name)

  1. Search with a good query (include brand/size if you can).
  2. If needed, select a variation.
  3. 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.
  • Skip products with in_stock: false. add_to_cart will also fail with error: "out_of_stock" and a message if stock ran out.

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

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.
