Server instructions

Tools for researching LienFi tax lien certificates. WE HOLD NO KEY. This server never signs and never submits a transaction for you. Tools return authorization state, balances, positions and an indicative quote for the wallet your operator authorized. Buying over MCP is not built yet; an authorized agent can buy over REST from its own wallet. Every yield the underlying API returns is GROSS: the platform takes a share of the gain over the purchase price when a lien redeems. Rank on net_apy, not on the API apy — they are different derivations, not the same number before and after a fee. A lien under a month from maturity has NO net_apy: a certificate pays once, so there is no year to restate the payoff over. search_liens returns those separately, ranked on net_return_pct. Research needs no credential: market_overview, search_liens and get_lien work with no Authorization header. Anything wallet-scoped needs one. When a tool refuses, the JSON body carries a stable `error.code`; on not_registered it also carries `handoff_url` — surface that link to your operator and STOP. Retrying will not register you, because that step happens in a browser. Call agent_status when a wallet-scoped tool refuses: it reports authorization and balances, which covers most refusals.
