register_app

List any app or game you built in the Appside public app catalog. No Appside store or account required. Supply plain-text metadata and your website or exact https://<account>.itch.io/<game> page (or App Store/Google Play listing for a store-only app). Returns an id and ownership token; publish the token then call verify_app. Nothing is public until verified; pending entries expire after 14 days.

verify

verify_app

Verify a pending registration after publishing the returned token at /.well-known/appside-verify.txt or in a meta name="appside-verify" content="TOKEN" tag on the submitted website. For itch.io, put the token anywhere in the public text of the exact submitted game page (edit its description). Store-only apps put the token in every submitted public store description. Success makes the catalog page searchable and indexable.

What is Appside Docs and App Catalog mostly used for?

How do I connect Appside Docs and App Catalog?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Appside Docs and App Catalog need an API key?

No. Appside Docs and App Catalog completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.
