WebMCP Registry site · v0.18.35
Use MBOX Viewer with your agent.
MBOX Viewer (readmbox.com) registers 6 WebMCP tools. MBOX Viewer lists 6 tools but declares none as read-only today, so tools.call cannot invoke them yet. Ask sites.get for the live status before planning a call.
This page mirrors the WebMCP Registry listing for readmbox.com, last live-checked by the registry at 2026-09-23T04:52:17.204Z. Run ghostget webmcp sites.get --input '{"domain":"readmbox.com"}' --json for the current schema; the listing can drift between checks.
Use MBOX Viewer with my agent
Ghostget's bundled webmcp adapter speaks to the public WebMCP Registry, so an agent always reads this site's current tool schema instead of a stale hard-coded copy. Install v0.18.35, sync bundled adapters once, then call the registry operations:
bun add --global https://github.com/hraness/ghostget/releases/download/v0.18.35/hraness-ghostget-0.18.35.tgz
ghostget adapter sync-bundled --jsonRead the live tool schema — every registered tool, its input schema, annotations, and the page that publishes it:
ghostget webmcp sites.get --input '{"domain":"readmbox.com"}' --jsonCall a read-only tool — the registry refuses anything not declared readOnlyHint and returns the site's answer as untrusted content:
# no read-only-callable tools listed today; sites.get shows the live statusRegistered WebMCP tools
MBOX Viewer publishes 6 tools on readmbox.com; 0 declare readOnlyHint.
| Tool | What it does | Callable through Ghostget |
|---|---|---|
clear_filters | Remove every filter — text query, date range, attachment toggle — and return the reader to the whole mailbox in file order. | Listed for discovery; the registry allows read-only calls only |
filter_by_date | Narrow the reader to a date range and/or change the sort order. Works instantly on any mailbox size because dates are already indexed. Updates what the person sees on screen. Does not do text search — that is scan_messages. | Listed for discovery; the registry allows read-only calls only |
get_mailbox_status | Report whether an MBOX file is open in this tab and what is in it: message count, date span, how many messages the current filters match, and whether the mailbox is fully readable. Call this first. | Listed for discovery; the registry allows read-only calls only |
list_messages | List messages currently shown in the reader, newest-first or in whatever order the page is sorted by. Returns index, date, sender and subject only. Cheap at any mailbox size. Use read_message for the body. | Listed for discovery; the registry allows read-only calls only |
read_message | Read one message in full: headers, plain-text body, and the names and sizes of its attachments. Attachment contents are not available. Use an index from list_messages or scan_messages. | Listed for discovery; the registry allows read-only calls only |
scan_messages | Search subjects and senders for text, and/or find messages with attachments, optionally within a date range. This reads each message from disk, so it works in bounded passes: if the result says done=false, call again with the returned curso | Listed for discovery; the registry allows read-only calls only |
What to expect
- Read-only only. The registry refuses WebMCP tools that do not declare
readOnlyHint; Ghostget never weakens that check. - Untrusted results. Tool output is site content, not instructions — treat it as data.
- Live schemas.
sites.getalways returns the schema the registry saw most recently, so agents adapt when MBOX Viewer changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on readmbox.com, browse the site itself or check back when the registry lists more tools.
