Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 767 tokens (~255/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management63
- Stability observed for 19 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the SENTINEL Washington Real Estate MCP server?
SENTINEL Washington Real Estate is a hosted endpoint at https://app.sentineliq.net/api/v1/mcp/public, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
nwmls_deadlines NWMLS deadline calculator ~269
Compute the standard NWMLS transaction deadline set from a mutual-acceptance date: earnest money (Form 21), seller disclosure delivery + buyer rescission (Form 17, RCW 64.06), title contingency (Form 22T), inspection (Form 35), financing (Form 22A), and FIRPTA certification (Form 22E). Business-day counts exclude weekends and Washington state holidays per RCW 1.16.050 — never plain calendar arithmetic. Washington/NWMLS transactions only. Dates are the standard form DEFAULTS computed from public rules (no NWMLS data or form text); the result flags dates landing on non-business days and includes a verify-against-the-executed-contract disclaimer that must accompany any advice built on these dates. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.
| Name | Type | Req | Description |
|---|---|---|---|
| closing | – | – | Optional contract closing date (on/after mutual acceptance), ISO YYYY-MM-DD. |
| financingDays | integer | – | Form 22A financing-contingency length. |
| mutualAcceptance | string | yes | Mutual acceptance date, ISO YYYY-MM-DD (within 5 years of today). |

wa_net_sheet Washington seller net sheet ~243
Estimate a Washington home seller's net proceeds: commission, graduated REET, title/escrow/closing costs, mortgage payoff, and optional HOA/tax prorations — every line item computed deterministically by the same engine SENTINEL's product uses. Use for 'what will the seller walk away with' questions on WA sales; WA counties only. The result is an itemized dict. Uses no third-party data. The result includes an 'attributions' array (upstream source lines and the NWMLS/DOR/county non-affiliation line) and a professional-advice disclaimer — pass both through to end users.

wa_reet Washington REET calculator ~194
Calculate Washington State Real Estate Excise Tax (REET, RCW 82.45) for one sale: graduated state brackets plus the county's local rate, computed deterministically by SENTINEL's production engine — never estimated. Use when you need the exact excise tax owed on a WA home sale (seller-paid by default). Washington State counties only. The result includes the per-bracket breakdown, the $5 DOR technology fee, and rate-assumption caveats (verify the DOR location code for city-level exceptions). Uses no third-party data.
