Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

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.

contentstring, required

The content to share (max 4MB).

ttlstring

How long the link stays readable. 5m–1d are free; 30d costs $1.

langstring

With format=code: the language to highlight (e.g. python, javascript, diff). Omit to auto-detect.

namestring

Pro, ttl=30d only: human-readable name appended to the URL as a slug.

formatstring

How to render the content: text (verbatim), markdown (rendered rich), code (syntax highlighted), or html (sanitized and rendered — best for visual output; inline CSS/SVG work, scripts are stripped).

passwordstring

Pro, ttl=30d only: password required to read the link. Access control, not encryption — content is plaintext at rest.

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

destructive

Argument	Type	Description
url_or_key*	string	Full ctxt.io URL, /3/<code> path, or bare code.
delete_token*	string	The delete_token from create_context.
