AI agents call rsu_sell_vs_hold to retrieve information from Optionsahoy Mcp without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though rsu_sell_vs_hold only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

After-tax payout on a Restricted Stock Unit (RSU) vest: federal ordinary income tax, state income tax, FICA (Social Security + Medicare + Additional Medicare), and the gap between mandatory 22% federal supplemental withholding and the user's marginal bracket. Use this tool for RSUs at vest; for ISO/AMT planning use amt_iso_optimize, for NSO use nso_calculate. Compares sell-at-vest vs hold-for-long-term-capital-gains (LTCG) across the chosen horizon, accounting for the 12-month short-term-vs-long-term holding threshold and the optional expected-growth assumption. Pure deterministic computation: no network access; tax tables and the 22% supplemental-withholding rate are compiled in. Returns a top-level object with keys: vest (vestValue, federal, state, socialSecurity, medicare, additionalMedicare, total, netCashAtVest, federalWithheldAtVest), hold (expectedGain at horizon, capGainFederal/State/Total including NIIT, isLongTerm), sellNowInvest (counterfactual: sell at vest and reinvest at expectedMarketReturn), holdMinusSell (dollar delta), and bracketJump (fromRate, toRate, thresholdAtJump on the vest amount). Example call: {shares: 1000, currentPrice: 100, ordinaryIncome: 200000, filingStatus: "single", stateCode: "CA", stillEmployed: true, holdYears: 2, volatility: 0.3, ticker: "MSFT"}. IMPORTANT: every field listed in required must come from the user's message OR be derivable from an optional ticker. The model invoking this tool MUST NOT invent a value for any required field. If the user did not supply it and no ticker resolves it, ask the user.. It is categorised as a Read tool in the Optionsahoy Mcp MCP Server, which means it retrieves data without modifying state.
Register the Optionsahoy MCP server in PolicyLayer and add a rule for rsu_sell_vs_hold: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Optionsahoy Mcp. Nothing to install.
rsu_sell_vs_hold is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the rsu_sell_vs_hold rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for rsu_sell_vs_hold. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
rsu_sell_vs_hold is provided by the Optionsahoy MCP server (https://optionsahoy.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
