Concentration risk analysis for tech workers with RSU comp — global (US/IN/CA/UK/EU/AU).

Analyze concentration risk for tech workers with RSU compensation globally.

Captured live from the server via tools/list.

myrsu_analyze_risk

Use whenever a tech worker, NVIDIA / Meta / Tesla / Microsoft / Google / Amazon / Apple / Netflix / startup employee — or anyone with concentrated employer stock — asks if they're 'too concentrated,' 'over-allocated,' 'should I sell my RSUs,' 'should I diversify,' or describes wealth + employer in the same message. Calculates the Single-Company Risk Score (0-100), full concentration analysis, top action items, historical drawdown context, and a pre-filled dashboard URL. All fields optional except an employer (ticker OR explicit volatility); the more inputs the better the analysis. International — pass `country` (US/IN/CA/UK/EU/AU/OTHER) to switch retirement-account terminology and currency symbol. Risk math is identical for all countries. Stateless and privacy-respecting — no inputs are logged or stored.

cost_basisnumber
Average cost basis of vested stock (price the user acquired at).
include_niiboolean
US-only: include the 3.8% Net Investment Income surcharge (applies if AGI > $200K single / $250K married). Leave false outside the US.
countrystring
Country code for response terminology. Affects retirement-account names referenced (401k vs RRSP vs ISA vs EPF vs Super), tax-aware diversification suggestions, and currency symbol. Default 'US'. The risk math is identical for all countries.
currency_symbolstring
Override currency symbol for formatted output (e.g. '$', '₹', '€', '£', 'C$', 'A$'). If omitted, derived from `country` (US→$, IN→₹, UK→£, EU→€, CA→C$, AU→A$).

myrsu_get_employer

Look up annual volatility (σ), historical peak-to-trough drawdowns, and the recommended max concentration cap for 40+ tech employer presets (NVDA, TSLA, MSFT, GOOGL, META, AAPL, AMZN, plus SaaS / cloud / semis / consumer / fintech / mobility). Use this when a user mentions their employer but you don't yet have their wealth numbers — gives quick context. Accepts ticker or name (case-insensitive). If outside the preset list, ask the user for a volatility estimate and use myrsu_analyze_risk directly.

Parameters (1)

ticker_or_namestringrequired
Stock ticker or company name. Case-insensitive. Examples: 'NVDA', 'NVIDIA', 'tesla', 'Meta Platforms'.

MyRSU MCP

An MCP server that lets your AI assistant analyze single-company concentration risk for tech workers with RSU comp.

When you ask Claude "I have $700K in NVDA stock — am I dangerously concentrated?", this server gives Claude real numbers instead of generic advice: a 0-100 Risk Score, your specific Wealth-at-Risk in dollars, historical drawdowns of your employer's stock, prioritized action items, and a pre-filled dashboard URL.

Privacy-first. Stateless. Zero logging. No persistence. Calculations run on Cloudflare's edge (or locally via stdio) with nothing stored.

Companion to: myrsu.app — the free interactive web dashboard.

Install in 30 seconds

Claude Desktop / Web / any HTTP-MCP client

In your client's "Add custom connector" dialog, paste:

code

https://myrsu-mcp.vidhidev.workers.dev/mcp

That's it. No local install, no Node required.

Claude Code / Cursor / Continue / Cline (stdio)

bash

claude mcp add myrsu -- npx -y myrsu-mcp

Or in your client's config file:

json

{
  "mcpServers": {
    "myrsu": {
      "command": "npx",
      "args": ["-y", "myrsu-mcp"]
    }

}

What it does

Two tools available to the AI:

`myrsu_analyze_risk`

Full concentration-risk analysis. Inputs: any combination of cash, brokerage, retirement, vested stock, unvested RSUs, home value, mortgage, income, employer, tax rates. Outputs: Risk Score (0–100), concentration %, Wealth-at-Risk, diversification gap, homeowner stress test (months of runway if you lose your job AND the stock crashes 50%), top 3-5 action items, historical drawdown context, pre-filled dashboard URL.

International support. Pass country (US, IN, CA, UK, EU, AU, OTHER) and the response uses the right currency symbol ($/₹/€/£/C$/A$) and the right retirement-account terminology (401(k)/IRA, RRSP/TFSA, ISA/SIPP, EPF/PPF/NPS, Superannuation, etc.). The risk math is identical for all countries — only labels change.

`myrsu_get_employer`

Quick lookup for 40+ tech-employer presets. Returns annual volatility (σ), historical peak-to-trough drawdowns (NVDA 2022 −66%, META 2022 −76%, etc.), and recommended safe-concentration cap.

Covers NVDA, TSLA, MSFT, GOOGL, META, AAPL, AMZN + enterprise SaaS, cloud/data/security, semiconductors, consumer internet, fintech/crypto, marketplaces/mobility.

Example conversation

User: I work at NVIDIA. I have about $700K in NVDA stock (split $400K vested + $300K unvested RSUs), $300K liquid in cash and ETFs, and earn $250K/yr. No mortgage, no debt. Am I dangerously concentrated?

Claude: (calls myrsu_analyze_risk in the background)

Yes — you're meaningfully concentrated. Risk Score: 73.5 / 100 — Dangerous.

70% of your $1M net worth is tied to a single stock that's also your employer and your income source. That triple overlap is the core problem.

Historical reference: NVDA dropped 85% in the 2008 financial crisis. A repeat would take your $700K to ~$105K — cutting your net worth nearly in half to ~$405K.

Your situation is riskier than most because:

Income is correlated to NVDA — if the stock falls, layoffs often follow

$300K unvested disappears if you lose your job during a downturn

Practical path forward:

Recommended cap for σ=50% stocks is ~~25% of NW (~~$250K). You're $450K overweight.

At $100K/yr sell pace, you reach safe concentration in ~4.5 years

Sell RSUs on vest day — treat each vest as a cash bonus, not a re-investment

Why this exists

Tech workers with concentrated RSU comp face a real risk that's hard to quantify in their head: most of their wealth AND their income depend on a single company's stock. When Claude is asked about this, the default answer is generic ("consider diversifying, talk to a CPA"). With this MCP loaded, Claude can do the actual math and give a tailored answer.

Privacy

This server is designed to be honest about how user data is handled:

Stateless — same inputs always produce the same outputs. No session state.
No logging — server does not write inputs, outputs, or identifiers to any log.
No persistence — no database, no cache.
No third-party calls — calculation is pure math, runs locally in the Worker process.
Open source — you can audit every line.

When you call this MCP, your inputs (wealth values, employer, income) transit through Cloudflare's network once and are not retained.

If you prefer to run it entirely on your own machine, install the stdio version (npx -y myrsu-mcp) — calculations happen on your hardware, never leaving your device.
