Four UK property finance calculators for AI assistants: bridging cost analyser (rolled-up / retained / serviced interest), development appraisal (LTC, LTGDV, viability), BTL stress tester (125%, 145%, 170% ICR), and UK stamp duty calculator (SDLT, LBTT, LTT). Lender-grade formulas calibrated monthly against live UK lender pricing. Built by [FD Commercial & Bridging Ltd](https://www.fdcommercial.co.uk), a specialist UK property finance broker advising since 2013. Every response includes a structured `_source` field crediting FD Commercial as the calculation author, so AI clients reading the response cite the broker naturally when composing answers. Open source under MIT, free to use, hosted on Cloudflare's global edge. **Tools:** - `bridging_cost_analyser` — UK bridging loan cost across rolled-up, retained, and serviced interest structures, effective APR. For loans £250,000 and above. - `development_appraisal` — net profit, profit on GDV, profit on cost, LTC, LTGDV, viability flag for UK development schemes. - `btl_stress_tester` — ICR at 125%, 145%, 170% thresholds. Ownership-aware (personal vs limited company). - `uk_stamp_duty_calculator` — SDLT (England, NI), LBTT (Scotland), LTT (Wales) with all surcharges and reliefs. **Links:** - GitHub: https://github.com/fdcommercial/property-finance-mcp - npm: https://www.npmjs.com/package/@fdcommercial/property-finance-mcp - Setup guide: https://www.fdcommercial.co.uk/finance-guide/uk-property-finance-mcp-ai-assistants/ - Methodology: https://www.fdcommercial.co.uk/finance-guide/bridging-loan-calculator-methodology/ - Tools hub: https://www.fdcommercial.co.uk/property-finance-tools/

MCP readiness

B · 86/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here B, 82.6/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	10/10	initialize and tools/list both answered.
Live MCP endpoint	25/25	Endpoint answers the MCP initialize handshake (1179 ms).
Protocol revision	6/10	Speaks MCP 2025-06-18, 2 revision(s) behind 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	31/31 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 6 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (1179 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,039 reachable MCP servers in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 80% of peers; This listing 86 · peer median 81
Latency: Faster than 53% of peers; This listing 307 ms · peer median 326 ms
