KI Alternativen MCP Server

List live, same-category alternatives to a well-known AI tool (e.g. 'chatgpt', 'notion-ai', 'figma'). Call this when a user asks 'what are the alternatives to X' or wants competitors/substitutes for a named product. `target` is the well-known tool's slug, not a listing slug from this catalog.

Create a Stripe checkout URL for one paid add-on on one listing, and return it for a HUMAN to open. Never present this as a completed purchase: nothing is charged until a person completes checkout in a browser. Returns an error when the listing doesn't exist, the add-on isn't purchasable yet (free early access), or payments aren't configured in this environment.

List the optional paid add-ons a maker can buy to promote their listing (name, one-sentence effect, price in USD). Listing is always free; these only ADD reach and are always labeled 'Sponsored'. Call this to see what's purchasable before create_checkout. During free early access (early-bird), offers are not yet purchasable and this says so (purchasable=false).

Submit a new AI tool to KI Alternativen on behalf of its maker. We fetch the submitted url and look for the KI Alternativen badge. Badge found (status QUEUED): no account is needed — the badge proves the maker controls the site. The listing enters the free review queue and goes live within 7 days if it passes review; the result has its listingUrl. Badge not found (status DRAFT): the listing is a private draft. The result carries badgeHtml — once it is on the page, a later re-check queues the draft (drafts are re-checked in rotation, 25 per run, one run every 6 hours, for 90 days), so do not submit again — and a claimUrl where the maker can sign up with the same email instead. Refused: our own domains, private or non-https hosts (error reserved_host), and a host that already has a live, queued or pending listing (error duplicate_host). Call this only when a user explicitly wants to list their own tool — never to submit a tool on someone else's behalf without their email. Rate-limited globally to 5 submissions per hour. Supply tagline, problemSolved, logoUrl and imageUrls whenever you can: they are what make the published listing look like a real product page rather than a stub.

Fetch the full public detail for one AI tool by its listing slug (as returned by search_tools' toolUrl, e.g. '/tools/acme-writer' -> slug 'acme-writer'). Call this after search_tools to get a tool's full description, launch date, revenue signals (verified or self-reported), and for-sale status. Returns null if the slug doesn't resolve to a live KI Alternativen listing.

Search the KI Alternativen catalog of live, published AI tools by a free-text query. Matches on tool name, tagline, or category name (case-insensitive substring). Call this first when a user asks to find, discover, or compare AI tools by keyword, use-case, or category (e.g. 'agents', 'writing assistants'). Returns up to 20 results.
