On 2026-10-26 the server answered initialize and tools/list without a sign-in. First answer in 218 ms.

• Its tools do let AI assistants answer questions about prices and hours, but not convert assistant chats into scheduled appointments; receive customer inquiries in a dashboard inbox.
• Checked on 2 of the 7 days it takes to judge reliability.

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 (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). 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

  Search the CoreLoop business directory. Start here: every other tool on this endpoint needs a business, and each result carries the `business_id` and `slug` you pass to them as the `business` argument. `business_id` is a PUBLIC, OPAQUE…

• check_business_availability

  One business's opening hours, whether it is open right now, and when it next opens. Phase 1 returns published hours, not bookable slots.

• compare_business_services

  Compare one business's services within a category or keyword, with a price/duration summary. Each row reports `match_type`, so you can tell an exact category hit from an incidental keyword.

• get_business_agent

  The canonical ids and endpoint URLs for one business — its own MCP and A2A endpoints, agent card, llms.txt and public page, under `protocol_urls`. A null URL means that surface is switched off for this business right now: do not construct…

• get_business_info

  Full profile for one business found through search_businesses: identity, locations, contact, policies, images, public documents and the languages it publishes in.

• get_business_services

  One business's service catalogue, with filtering, sorting and pagination. Page with `offset`/`limit` and read `has_more` — the order is stable, so a second page will not repeat or skip a service.

• send_business_inquiry

  Send a message to one business. This has a real side effect — it notifies the owner and delivers an email — and is rate-limited both per business and across this directory, so send one considered inquiry rather than a broadcast.
