Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names generally align with their purpose (e.g., 'search_worlds', 'delete_world')
- Some tools include useful constraints (e.g., rate limits, required permissions)
Weaknesses
- Multiple descriptions are incomplete or cut off mid-sentence
- Parameter types like 'body' are defined as objects without further clarification
- Several tools with similar functions (e.g., 'get_world' vs 'get_my_world') lack clear differentiation
- Error handling and constraints are inconsistently documented across tools
search_worlds— Description cut off mid-sentence, missing critical information about 'liked' filter behaviorget_my_profile— Parameter names (worldId, creatorId) imply functionality not clearly explained in descriptioncreate_comment— Rate limit information (30 per hour) not clearly separated from other constraintsget_community— No mention of required permissions or error conditions in description

Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
search_worldsBrowse and search published worlds. Sort by newest, liked, or trending. The days filter accepts 1, 7 (default), or 30 UTC calendar days including today. Use days=all with sort=newest to discover all published worlds. Newest filters publication date unless days=all or creator is specified; liked and trending rank activity during the window and may include older worlds. Search text can include exact #tags; custom tags are supported without a fixed vocabulary. Liked and trending require the community flag. Follow nextCursor with unchanged filters until null. Drafts and offline worlds are excluded. Public; no authentication is required.

- Publish a webpage to a live URL, straight from your AI.yapp.page
Yapp turns "build me a page and publish it" into a live URL. Connect once (browser OAuth, or a token for terminal clients) and your AI can publish a webpage from HTML, or host a PDF, image, or ZIP exactly as-is to a public `<slug>.yapp.page` URL in seconds, then update, password-protect, set expiry, attach a custom domain, or read form submissions, all by asking. Free to start; no local install. **Tools (15):** `publish_page`, `publish_file`, `update_page`, `delete_page`, `get_page_stats`, `list_my_pages`, `rename_page`, `change_page_slug`, `set_page_expiry`, `set_page_password`, `list_submissions`, `add_custom_domain`, `list_custom_domains`, `check_custom_domain`, `remove_custom_domain`.

- Just Publishmcp.justpublish.ai
**Just Publish** turns a website you built with AI into a live, public URL — without leaving the chat. No git, no CLI, no build step, no dashboard, and no login to fumble through. You hand it your files, it hands back a working link. It's built for the person who made a site with ChatGPT, Claude, or Cursor and just wants it online. ### How it works Call `deploy` with your files (HTML, CSS, JS, images) and an email. You get back a live `url`, a `site_id`, and an `edit_token`. Keep the token and you can update the same site anytime — either a full redeploy or a single-file edit. That's the whole flow. ### Tools - **`deploy`** — Publish a static site to a public URL. First call creates a new site and returns its `url`, `site_id`, and `edit_token`; pass those back to update it in place. - **`update_site_file`** — Change one or a few files on an existing site without resending the whole thing. - **`get_site_files`** — Read what's currently live before you edit. ### Who it's for Non-tech
