OpenAPI Specification
openapi: 3.2.0
info:
title: SENTINEL Property Research MCP API
version: 1.5.1
description: 'Per-address computed research for King, Snohomish, Pierce, and Whatcom counties, Washington: deterministic REET, seller net sheet, NWMLS deadline and monthly-payment calculators, seller-scenario and offer comparisons, and a seller packet combining math with optional cached evidence and Markdown (one metered answer per packet). A sanitized county property record accepts an address or county plus parcel ID, excludes owner identity, and carries exact field observations with explicit gaps. Permit history supplies City of Seattle building records and observed changes with issuing-agency coverage boundaries; listing status / price / days-on-market appear only when the listing row is RentCast-licensed, and portal links, photos and portal valuations never appear. An attributed market snapshot. Every response carries an `attributions` array whose `required` entries must be reproduced wherever the data is shown. Not affiliated with or endorsed by NWMLS, the Washington Department of Revenue, or any county.'

description: 'Keyed stateless JSON-RPC 2.0 dispatch — all ten tools, metered.
Auth and rate limits run before JSON-RPC parsing. Execution quota is
reserved only after tool arguments validate, leaving discovery usable
when a quota is exhausted. These rejections use HTTP errors with no-store.
Signed-out requests (only possible with MCP sign-in on) list every tool,
run the free calculators unmetered and answer keyed calls with a 401.'

description: 'Authless JSON-RPC 2.0 dispatch — the three calculators, never metered.
No key, no account, no DB session: every tool here is pure deterministic
math over the engines in src/deals. Abuse control is the per-IP
``public_mcp`` bucket (429 in the surface''s structured envelope with
Retry-After, headroom in X-RateLimit-Remaining) plus the body-size cap
(413 before any parsing); the keyed buckets and the usage ledger are
never touched.'
