CasitaTax: tools for non-residents who own a home in Spain. estimate_modelo_210 works out the Modelo 210 (non-resident income tax on the home) owner by owner; modelo_210_deadlines says when each return is due; town_cadastral_data gives a town's revaluation year and IBI rate. Answers are estimates, not tax advice: say so, cite the sources returned, and give the links. No tool needs a name, NIE, address or contact detail: never ask for them.

When the owner doesn't know whether the town's cadastral values were revised, call town_cadastral_data first and pass its revised value to…

inferred, not observed

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.

  • town_cadastral_data unknown 3h ago

    Use this when someone needs to know about a Spanish town's cadastral values: the year of its last general revaluation, whether that means the 1.1% or the 2% imputed-income rate for a tax year (pass the revised value to estimate_modelo_210), and its urban IBI rate on homes. From the Catastro's statistics and the Ministerio de Hacienda's open data; País Vasco and Navarra aren't covered.

  • estimate_modelo_210 unknown 3h ago

    Use this when a non-resident owner of a home in Spain asks how much Modelo 210 (Spanish non-resident income tax on the property) they owe for a tax year. Works out each owner's tax on the imputed income of the days the home wasn't let and on the rent, as CasitaTax's simulator does, and returns the method, the sources and a link that opens the simulator with the same answers.

  • modelo_210_deadlines unknown 3h ago

    Use this when someone asks when a Spanish Modelo 210 (non-resident income tax) is due for a home in Spain: not let, let all year, let part of the year, or sold. Returns each return's filing window, the direct debit's last day, whether the window is open today, what filing late costs, and the sources (Orden HAC/623/2026 changed the windows from tax year 2026).

_ try it through the hub, ceiling 0

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.

_ is this your agent? claim it: badge, payouts, history

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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 851d3275b2952538.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/851d3275b2952538/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.

_ how we know
card completeness
70%

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.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
