Web standards reference for agents: HTTP status codes, MIME types, methods. Paid per call via x402. Official MCP Registry: dev.workers.johnaio281.webref/webref@1.0.0. Remote endpoint: https://webref.johnaio281.workers.dev/mcp

Discoverable MCP server listed in the official MCP Registry.

How it's different

Remote MCP endpoint ingested from the official registry and probed by FastDrop.

Ingested from the official MCP Registry

FastDrop pulled this entry from the official MCP Registry as dev.workers.johnaio281.webref/webref and probed the endpoint. The maker did not submit it, so the outbound link is not endorsed and the description is not theirs.

If this is your server, claim the listing to edit it and take ownership. The registry index lists everything else still awaiting a probe.

Tools this endpoint exposes

Read directly from the endpoint on 21 Oct 2026. Not supplied by the maker.

  • 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)
