Registry code: 859e0cb4421afd78
HouseExhale helps households find out whether their bedrooms get enough fresh air at night, try free fixes, and, if needed, get a balanced ventilation system (an HRV or ERV) installed and proven. It is free for homeowners.
Connection help: read the houseexhale://setup resource for manual setup in Claude, ChatGPT, Claude Code and VS Code, or visit https://houseexhale.com/ai#manual-setup. The public endpoint is https://houseexhale.com/mcp (Streamable HTTP, no authentication).

- Is houseexhale live?
- Yes — it answered the hub's last check (checked 46m ago). It answered 100% of checks over the last 30 days.
- Is houseexhale free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does houseexhale have?
- 5 tools: find_rebates, units_to_ask_about, find_installers, check_ventilation_unit, explain_co2_reading.
- Is houseexhale 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.

what callers paid
Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run
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.
find_rebates unknown 46m ago
What HouseExhale’s research found for a state (by ZIP code or state): utility and state programs that pay toward an HRV or ERV by name, other ventilation rebates, air sealing and insulation help, the state’s federal home energy rebates, state tax credits, and the status of the federal tax credits. Each with its link and date. Never promises eligibility.

Lists up to three reviewed HRV/ERV families whose HVI-certified airflow covers what the household’s bedrooms need at night, with margin: units to ask installers about, never a single pick or a recommendation, and never paid placement. Also returns the night airflow target and how it was worked out.

Lists HRV and ERV installer companies for a US ZIP code in HouseExhale’s neutral order, with its ordering rule and coverage limits. Returns member companies where the installer program is open, otherwise researched companies from public pages covering the Colorado Front Range and New England. Contains no sponsored cards or paid recommendations. Does not contact anyone.

Checks a quoted HRV or ERV against bedroom airflow needs using exact-model HVI-certified data. Returns a screening verdict, reasons, assumptions and questions for the installer. Ambiguous model names return candidates for clarification rather than a guessed model. Does not provide a permit-ready design or guarantee installation performance.

Explains a bedroom CO₂ reading against the precautionary 800 ppm average-while-asleep goal: band, distance from the goal, whether the measurement is comparable, signs of a monitor reading low, and free fixes with trade-offs. The goal is not a health limit. Door-open nights appear only as one-night tests, not fixes.

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 id859e0cb4421afd78.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/859e0cb4421afd78/claim.

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.
