mcphost

host.quickstart

Return the shortest ordered sequence of calls to a working tool of kind, with your namespace and a filled-in example already substituted in, plus the current limits and a try_before_call table naming the one dry-run tool for each case. Read-only -- this call alone never creates a tenant. Call this before host.tool_publish if you're not sure what a spec should look like. Unauthenticated callers get a worked example with no tenant data; any other host./billing. call creates a tenant on first use, no signup required.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`kind`	No	Which registered kind to return a worked example for, e.g. echo, http, python -- or a job-word alias (webhook, event, cron, ...) for its recipe. Omit to see every kind, alias and recipe name.
`tenant_key`	No	The key `signup` returned. Optional on the connection that ran signup (or host.redeem): that connection is already bound to the tenant it created, so later calls on it need no tenant_key. On a connection with no Authorization: Bearer header and no prior signup, omitting it implicitly signs that connection up as a brand-new tenant and runs this call as it -- see host.whoami's source field. When both a header and this argument are present, the header wins.
