Worth a look

  • Tools that delete, send or pay without telling the client so: cancel
  • Tools that change data, on a server that answers without a sign-in: modify, cancel

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

    Start here. Every result carries trust (facts with who vouches for each and until when, lapsed facts, the job record); trust never changes the order, the price, who is eligible or what needs approval. A search result is not a promise…

  • discover

    Describe one merchant: services with pricing_model (packages: each package with its price, limits, kinds and the tasks it includes; the price is the cheapest package that fits the whole home and does every must-have task), typed inputs…

  • quote

    Quote one merchant's service. Every quote is a record: it returns transaction_id, quote_id, job_version and state quoted (or quote_incomplete). Pass transaction_id to quote the same job again (its next version; everything asked for before…

  • hold

    Reserve one window from a quote: the quoted job becomes held (same transaction_id). An expired or replaced quote answers QUOTE_EXPIRED: quote again. M-19: pick a window of the quote's job_hours; a window of another length, or one no…

  • book

    Commit a hold with the customer's details. Returns booked, or pending_approval (the owner must say yes: the quote's booking_authority was approval_required, or the owner's booking setting tightened since; the time stays reserved; poll…

  • modify

    Commit a change to a booked job: first quote it again with its transaction_id, then modify with that quote_token, optionally moving it to another window. The job stays booked; the old version and price are kept. The answer and every…

  • cancel

    Cancel your own held, waiting (pending_approval) or booked job and release the slot. Optional reason: customer_changed_plans, customer_booked_elsewhere, booked_in_error, customer_other. The answer carries cancellation (by, at, reason, fee…

  • status

    The authoritative state of one of your jobs and everything needed to act on it: the job (current version), price, quote, window, approval (what needs the owner's yes and why: reasons, the deadline, what happens at it), commitment (who…

  • taxonomy

    The fixed word list (version, groups, every key with its label and synonyms) agents use to describe a job and a home. Public, no key; the same answer as GET /api/v1/taxonomy/house_cleaning. Word list version 6.

  • register

    Get your own key, no human needed. Send agent_name (what your agent is called), owner_label (the plain name business owners will see next to a job, 1-40 characters) and contact_email. The key (ct_live_...) is in the answer ONCE: keep it…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "booking": {
      "type": "http",
      "url": "https://commontape.com/api/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http commontape https://commontape.com/api/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://commontape.com/api/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
