# TrueCalci Precision Compute Engine Deterministic statutory, financial, and engineering computational tools for AI agents, developers, and autonomous workflows over the Model Context Protocol (MCP). ### Capabilities (25 Verified Engines): - **Specialist FinOps:** Remote Contractor vs. W-2 Parity, S-Corp Reasonable Compensation (IRS Rev. Rul. 74-44), Solo 401(k) Shelter, Cross-Border FX Drag, Billable Capacity Floor. - **Global & Cross-Border Tax:** US Form 2555 FEIE Nomad Stacking, B2B Foreign Withholding Radar, European VAT/Sales Tax, Indian Section 115BAC Income Tax, Statutory GST. - **Quantitative & Physics:** Black-Scholes-Merton Options & Greeks, US Mortgage (PITI & PMI), Euler-Bernoulli Beam Bending, 2D Ballistic Projectile Motion, Casio fx-991 Simultaneous & Linear Equation Solver. ### Zero Hallucination Guarantee: All calculations execute deterministically in sub-millisecond edge isolates with IEEE 754 precision and statutory legal references.

MCP readiness

B · 88/100

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, 86.0/100), 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 (698 ms).
Protocol revision	10/10	Speaks the current MCP revision 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	22/22 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 29 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	0/5	How to authenticate is not stated.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (698 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 95% of peers; This listing 88 · peer median 81
Latency: Faster than 36% of peers; This listing 448 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Verified identity −5 — Claim the listing and prove control of its domain.
Now: Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Auth declaration −5 — State how to authenticate (an auth scheme, or that none is needed).
Now: How to authenticate is not stated.
Freshness + modern flags −1 — Keep the listing current in the registry or source it comes from.
Now: seen in a source within 7 days.
