Tools 10 found in our last check

• pricing_conversation

  Ask Last Price what pricing inputs are missing. Start with request: {}, return its questions to the caller, then send continuation.request and answers. Prepare is free and does not compute. When ready, action compute uses the existing authenticated pricing API; configure a crede…

• compute_price

  Compute a price. Returns the price, the function that produced it, the metered cost and a `trace` of each stage. Send currency plus unit_cost (what the work costs you) or current_price. Missing inputs return an error naming them. For a competitor offer, put competitor_price, com…

• verify_price

  Ask whether a price makes sense for its context, rather than what the price should be. Returns a verdict (within_band, too_high, too_low, or unknown), the band it was judged against, a signed deviation from the reference, a confidence, and the evidence behind it. A verdict of "u…

• report_outcome

  Report whether a price from compute_price was used: once the buyer has accepted or turned down a price, report it. Pass receipt.id from that result as usage_event_id, or omit it to report the last price compute_price returned on this connection or tools instance, once (the hoste…

• list_functions

  List the pricing functions registered for the authenticated tenant.

• get_receipt

  Get the receipt for one of your workspace's priced calls, by its usage event id (the id list_usage_events returns and report_outcome takes): what was priced, by which function and agent, when, the amount, how it was paid, and the outcome if one was reported. Receipts are made on…

• search_tools

  Find the Last Price tool for a task. This connection lists only the tools that reach a price; the server has over 300 more (pricing functions, routing, experiments, webhooks, billing, orders, the marketplace and more). Pass query, a few words for the job, and get back the best m…

• call_tool

  Run any Last Price tool by name, including one this connection does not list. Find the name and its arguments with search_tools first. What it does, and whether it changes anything, is what that tool says.

• register_agent

  Sign up with no key and no human: creates a sandbox workspace of your own and returns its API key (shown once), its daily limits and a claim link a person can open to take the workspace into their account. Pass name (2 to 64 characters, such as your-system/role-name), and option…

• use_api_key

  Use a Last Price API key you already hold (a saved file, LASTPRICE_API_KEY) in this MCP connection, when it was opened without one: pass api_key. On the hosted MCP server this session then runs as that key's agent, so the tools that need a credential work at once with no header…
