Deletes or cancels 1Claude Code: deny
  • delete_contextDelete a ctxt.io link you created.No findings

    Why it is in this group

    • The name "delete_context" says "delete": a word for removing or ending something.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    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.

    Annotations the server declares

    • destructiveHint: true
    • idempotentHint: true
    • openWorldHint: true
    • readOnlyHint: false

    Why it is in this group

    • The name "create_context" says "create": a word for a change.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "read_context" says "read": a word for reading.
    Description, as the server wrote it
    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.

    • destructiveHint: false

    • readOnlyHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__ctxt__read_context"
    ],
    "ask": [
      "mcp__ctxt__create_context"

    "deny": [
      "mcp__ctxt__delete_context"
    ]
  }

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as ctxt. Review it before you use it.
