Kong Reviews tools for choosing infrastructure vendors and estimating what they cost at scale. Start with recommend_stack: pass the product description in plain language and it reads the requirements and plans the stack in one call. Then show the user the requirements it read, ask them to confirm, and call plan_stack with any corrections. For one vendor use estimate_cost or find_cost_cliffs; for a category use compare_vendors; for a whole stack over time use project_stack. When something changes (bill, growth, a needed feature), use evaluate_change: it compares stay, optimise in place and…

- Is kongreviews live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is kongreviews free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does kongreviews have?
- 18 tools: list_capabilities, get_pricing, compare_vendors, project_stack, find_cost_cliffs, get_saved_stack, delete_saved_stack, delete_account, ….
- Is kongreviews safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

List the stacks the signed-in user saved, newest first, with their monthly cost when saved and a link to each.

Re-run a saved stack with today's catalogue and compare it with when it was saved: monthly cost then and now, picks that changed, and vendors whose pricing changed. Use it when the user asks about a stack they saved, or whether prices moved. Pass the id from list_saved_stacks. Needs sign-in. How to present the result: show the stack table (pick and runner-up per category, monthly cost now and at forecast) and the totals. For each price give its source's verified date, or say it is unverified seed data. Show every caveat word for word; never round, merge or drop one. Mention requirement gaps, blockers and trade-offs. Link share_url so the user can open the full result on kongreviews.com. Do not add vendors or prices that are not in the result.

Permanently delete the signed-in user's Kong Reviews account: their GitHub sign-in link and every saved stack. This cannot be undone. Only call it when the user explicitly asks to delete their account, after telling them what will be removed; pass confirm exactly as "delete my account". Needs sign-in.

Start here. Describe the product in plain language and get a recommended stack with costs now and at scale, in one call. Write the description as the user would: what the product does, who signs in and how, how it charges, which emails it sends, compliance or data-region needs, and expected users now and in 12 months. Example: "A booking app for yoga studios. Members sign in with Google and pay a monthly subscription. Studios get paid out. EU data. 2,000 users at launch, 20,000 within a year." Pass a PRD as the description if you have one. Numbers you pass (mau_now, mau_forecast, budget_monthly_usd, profile_id) override what is read from the text. Before treating the plan as final, show the user the requirements it read (each quotes its sentence) and the open questions, and ask them to confirm or correct them; then call plan_stack with the corrected requirements. How to present the result: show the stack table (pick and runner-up per category, monthly cost now and at forecast) and the totals. For each price give its source's verified date, or say it is unverified seed data. Show every caveat word for word; never round, merge or drop one. Mention requirement gaps, blockers and trade-offs.

Turn PRD or spec text into structured requirements (scale, capabilities, compliance, regions, budget) for plan_stack, without planning. recommend_stack does both in one call. Each requirement quotes the sentence it came from. Show them to the user to confirm before planning. Without a model on the server it reads the PRD with keyword rules (mode "rules") and also returns the capability vocabulary and instructions: as an assistant, prefer doing the extraction yourself and use the rules result only as a starting point.

Given confirmed requirements as capability ids, recommend a vendor per category with a runner-up, requirement fit, cost now, cost at forecast scale, year-one cost after perks, cost cliffs, trade-offs and blockers. Use recommend_stack instead when you only have a plain-language description. Example: {"mau_now":5000,"mau_forecast":20000,"profile_id":"booking_marketplace","requirements":[{"capability":"auth.google"},{"capability":"payments.merchant_of_record"}],"founder":{"gateways":["mercury"]}}.

When something changes (bill too high, growth, a missing feature such as SSO, a renewal), compare staying on the current plan, optimising with the same vendor, and switching vendor, including one-off switching cost and the month switching pays off. Example: {"category":"auth","current":{"vendor_id":"clerk","plan_id":"pro"},"mau_now":11000,"monthly_growth":0.18,"requirements":[{"capability":"auth.saml_sso"}]}. How to present the result: show stay, optimise and switch side by side with cumulative cost at each month given, the break-even month and any problems; show every caveat word for word.

Save a recommended stack to the signed-in user's Kong Reviews account so it can be reopened later and compared with current prices. Pass the share_url from recommend_stack or plan_stack (preferred) or the plan_stack arguments, plus a short name such as "Yoga booking MVP". Needs sign-in: if the user isn't signed in, the app will ask them to connect their Kong Reviews account. Only save when the user asks to keep or save a stack.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id74e577aa11a9b8fd.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/74e577aa11a9b8fd/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
