    Median latency 493 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

Capabilities

Tools 3

create_context

Share text, markdown, code, or HTML as an auto-expiring ctxt.io link. For visual output (styled reports, tables, charts, diagrams) prefer format=html with self-contained HTML: inline CSS and inline SVG render fully; <script> is stripped server-side and JavaScript never runs, so keep it static. Free expiries: 5m, 30m, 1h (default), 8h, 1d — these return the share URL immediately. ttl=30d and the Pro options (name, password) cost $1 one-time: the link is created in a pending state and the result includes a payment_url a human can open in a browser to complete checkout (platforms enrolled for agentic payments receive an acp block instead and can pay programmatically); until payment the link lives 1 day without Pro features. Anyone with the link can read it. The returned delete_token authorizes deletion via delete_context — keep it private.

Discovered
delete_context

Delete a ctxt.io link you created. Requires the delete_token returned by create_context. Immediately removes public access and requests backing-storage deletion. Destructive and not undoable — confirm with the user before calling.

Discovered
read_context

Fetch the content of an existing ctxt.io link. Accepts a full ctxt.io URL, a /3/<code> path, or a bare code. Password-protected links need the password argument.
