Paid via x402. ## Connect - streamable-http: `https://webref.johnaio281.workers.dev/mcp` ## Tools (as reported by the server, not verified) - `http\_status`: Look up an HTTP status code: what it means, what the client must do, whether it is retryable, whether it is safe to replay, the defining RFC and the common causes. \($0.003 per call\) - `status\_for\_situation`: Find the HTTP status code that matches a described situation, when the code is not known in advance — for example 'the caller is being rate limited' or 'upstream returned garbage'. \($0.005 per call\) - `retry\_advice`: Decide how a client should react to a status code: retry with backoff, check the outcome before retrying, or do not retry. Includes a suggested backoff schedule. \($0.005 per call\) - `mime\_type`: Look up a MIME type by full type or by file extension: the top-level type, what it is for, and the usual file extension. \($0.003 per call\) - `list\_mime\_types`: List or search MIME types by top-level type or by keyword, for example image types or anything to do with calendars. \($0.003 per call\) - `content\_type\_advice`: Check whether a Content-Type header matches what an endpoint kind expects, and say what to send instead when it does not. \($0.003 per call\) - `http\_method`: Describe an HTTP method: whether it is safe, whether it is idempotent, whether it carries a body, and what it is for. \($0.003 per call\) - `time\_until`: How much time is between two instants: the direction, the total in every unit, and a day/hour/minute/second breakdown. Use it to compute a retry delay, a rate-limit reset, or whether a deadline has passed. \($0.003 per call\) - `describe\_instant`: Describe an instant: its date, weekday and time in UTC and in Tehran local time \(UTC+03:30\), plus the Unix timestamp. Use it when a response carries a timestamp and the local date matters. \($0.003 per call\) - `weekday\_of`: Which day of the week a date falls on, and whether it is a business day. Use it before scheduling work or setting a deadline that lands on a weekend. \($0.003 per call\) - `business\_days\_between`: Count the business days between two dates, excluding weekends. Use it to turn a calendar deadline into a working-day deadline. Public holidays are not excluded, so the count is an upper bound. \($0.005 per call\) - `add\_duration`: Add a duration to an instant and get the result, in UTC and in Tehran local time. Use it for a TTL, a lock expiry, or a token lifetime. \($0.003 per call\) - `convert\_duration`: Convert a duration between units and get it in plain language. Use it to express a timeout in the unit the caller asked for, or to check whether a limit is seconds, minutes or milliseconds. \($0.003 per call\) - `unix\_time`: Convert between a date and a Unix timestamp, in either direction. Use it when a payload carries one and the other is needed. \($0.003 per call\) Measured by MCP Station. Methods: https://mcpstation.net/methods.html · Terms: https://mcpstation.net/terms.html
