Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• search_businesses

  Find businesses, merchants and websites in the tunnel knowledge base by name or topic. Start here: every other tool needs a `slug`, and this is where a `slug` comes from. Returns an array of summaries, each with `slug`, `kind`, name…

• get_business

  Read the full profile of one business. Returns identity, contact details, address, social profiles, offerings, FAQ, `verification` and any machine-readable endpoints we publish for it. Absent information is named in `missing` rather than…

• check_merchant_verification

  Check live what a merchant has actually been verified to, and by whom. Call this before acting on a claim that matters — a profile is a cached summary, this is the current answer. Returns `level`, a signed attestation, an expiry date and…

• ask_business

  Ask one specific question about a listing and get an answer from the registry, with no human involved. Try this before contact_business: it is instant, free, and does not put a message in someone's inbox. Returns either an answer or an…

• ask_business_freeform

  Same answers as ask_business, but you send the person's own words instead of choosing an intent, and the reply comes back in the language they used. Supported languages: en, ro, ru, de; anything else is answered in English. Prefer…

• check_escalation

  Read the answer to a question that had to go to a human. Use the `escalation.ref` that ask_business_freeform returned when its outcome was "escalated". Returns a `state` and, once there is one, the business's own `answer` in their words…

• check_commitment

  Read a commitment you were given by commit_order, including whether the business has since withdrawn it. Returns `state`: "issued" means it stands, "repudiated" means the business said they cannot honour it, with their stated reason. A…

• get_rate_card

  Read the prices a business has authorised us to quote on their behalf. Returns `published` and, when true, a `rateCard` holding a currency, an optional minimum charge and `items` — each with a `code`, a label, a unit and an amount. Those…

• request_quote

  Price a specific set of line items against a business's rate card. Call get_rate_card first and name `code` values from it; we do the arithmetic. Returns `quoted`. When true you get `total`, `lines` showing what each one came to, and…

• check_availability

  Find out when a business is actually free. Worked out per call against their opening hours, their notice period, their blackout dates and what is already booked — there is no stored list of free times to be out of date. Returns `known`…

• commit_order

  Place a binding order with a business, inside limits they set in advance. This is the only tool here that commits anyone to anything. Either name the figure yourself, or send `items` from get_rate_card and we price them from the…

• cancel_order

  Cancel an order you placed with commit_order. Returns `settled`. True means it is cancelled, the business has been told and their day is free again. False comes with a `reason`: "inside-cancel-window" (later notice than they said they…

• reschedule_order

  Move an order you placed to a different date, or a booking to a different slot. The price, the items and the quantity are unchanged — this moves WHEN, nothing else. To change what was ordered, use request_order_change. A booking made for…

• request_order_change

  Raise anything else about an order that already exists: a change to what was ordered, a refund request, or a problem with what was delivered. This tool never settles anything, and that is deliberate. Changing an order re-prices it and a…

• contact_business

  Open a conversation with the person behind a listing. The message arrives in their dashboard inbox and they reply when they get to it — this is asynchronous, not a chat, and nobody is obliged to answer. Returns a `conversation_id` and a…

• check_replies

  Read a conversation you opened with contact_business, including anything the business has replied since. Returns the whole message thread and its status. Poll it; there is no push. Authentication: the `conversation_id` and `token` from…

• send_followup

  Add another message to a conversation already opened with contact_business. Returns the updated message thread. There is a cap on messages per conversation, so send one considered follow-up rather than several fragments. Authentication…
