Claude Code: deny. ### `tinyurl_change_destination` - The description's first verb is "write": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text WRITE: point an existing short link at a new destination. DESTRUCTIVE: everyone who opens the short link is sent to the new URL from now on and the old destination is overwritten. The new URL must be http(s). PATCH /change. ``` ### `tinyurl_set_link_archived` - The name "tinyurl_set_link_archived" says "set": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text WRITE: archive an active short link (archived = true) or restore an archived one (archived = false). Archiving moves the link to the archived list; nothing is deleted and it can be restored. The API's archive endpoint is a toggle, so the link's current state is read first and nothing is changed when it already matches, and the state afterwards is checked. Do not run two archive calls for the same link at once. GET /alias/{domain}/{alias}, then PATCH /archive. ``` ### `tinyurl_update_link` - The name "tinyurl_update_link" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text WRITE: change an existing short link's alias, tags, expiry, description or click-analytics switch. At least one new_* field is required. DESTRUCTIVE for what it replaces: new_tags REPLACES all existing tags, and renaming the alias (new_alias) makes the old short URL stop working. The destination URL is changed with tinyurl_change_destination. PATCH /update. ``` ## Changes things (1) Creates or changes something that can be changed back. Claude Code: ask. ### `tinyurl_create_link` - The name "tinyurl_create_link" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text WRITE: create ONE new short link for an http(s) destination URL. Optional custom alias (5-30 characters on tinyurl.com), domain (tinyurl.com or a branded domain), tags, expiry and description. Not idempotent: calling it again without an alias creates another link. Returns the new tiny_url. POST /create. ``` ## Only reads (4) Looks things up and changes nothing. Claude Code: allow. ### `tinyurl_count_links` - The name "tinyurl_count_links" says "count": a word for reading. Description, as the server wrote it: ```untrusted-server-text How many short links the account has (active or archived), optionally within a creation date range or filtered by alias or tag. GET /urls/{type}/count. ``` ### `tinyurl_get_analytics` - The name "tinyurl_get_analytics" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Aggregated click analytics for the account, or for one link (alias) or one tag, from a start date. report: timeline (clicks over time; interval minute/hour/day/week/month), general (browsers, operating systems, devices), weekday and hour (popularity), top_sources (referrers), top_languages, location (countries, or the regions of one country via region = ISO 3166 alpha-2 code). Which reports are available depends on the account's TinyURL plan. Visitor-level raw logs are not exposed. GET /analytics/*. ``` ### `tinyurl_get_link` - The name "tinyurl_get_link" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Details of one short link: destination URL, tiny_url, tags, created/expires dates, archived/deleted flags, analytics settings, total hits and owner. GET /alias/{domain}/{alias}. ``` ### `tinyurl_list_links` - The name "tinyurl_list_links" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the account's short links (type available = active, archived = archived), optionally created within a date range or filtered by alias or tag. The TinyURL API does not page this list: at most `limit` items (default 50, max 200) are returned together with the total, so narrow with from/to/search when truncated is true. GET /urls/{type}. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `tinyurl`: ```json { "permissions": { "allow": [ "mcp__tinyurl__tinyurl_get_link", "mcp__tinyurl__tinyurl_list_links", "mcp__tinyurl__tinyurl_count_links", "mcp__tinyurl__tinyurl_get_analytics" ], "ask": [ "mcp__tinyurl__tinyurl_create_link" ], "deny": [ "mcp__tinyurl__tinyurl_update_link", "mcp__tinyurl__tinyurl_change_destination", "mcp__tinyurl__tinyurl_set_link_archived" ] } } ```
