## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_context`

- 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:

```untrusted-server-text
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.
```

## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_context`

- The name "create_context" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `read_context`

- The name "read_context" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `ctxt`:

```json
{
  "permissions": {
    "allow": [
      "mcp__ctxt__read_context"
    ],
    "ask": [
      "mcp__ctxt__create_context"
    ],
    "deny": [
      "mcp__ctxt__delete_context"
    ]
  }
}
```
