AI agents call concentration_analyze 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 concentration_analyze 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.

Single-stock concentration risk analysis on an existing position. For standalone hedge pricing use protective_put_price; for the tax math on the option exercise or RSU vest that created the concentration, route to amt_iso_optimize / nso_calculate / rsu_sell_vs_hold first. Quantifies drawdown exposure at 30/50/70% downside, then compares three after-tax strategies over a three-year horizon (sell-down to target weight, hold, hedge with put or zero-cost collar), accounting for federal LTCG, state tax, the 3.8% Net Investment Income Tax (NIIT), and reinvestment opportunity cost. totalAssets (concentrated position + everything else) frames risk relative to the portfolio and MUST come from the user, never inferred. Returns a top-level object with keys: concentration (position/totalAssets), riskBand (Low / Moderate / Concentrated / Highly concentrated / Extreme), isLongTermToday, longTermDate, daysUntilLongTerm, lossExposure ({drop, dollarLoss, newConcentration} for 30/50/70% drops), waitForLtInsight, schedule (yearly sales with per-year tax), hedging (NFV + cost when hedgeChoice provided), sectorContextLine, advisorBenchmarkLine. Example call: {positionValue: 400000, costBasis: 100000, acquisitionDate: "2022-01-01", sector: "tech_software", stateCode: "CA", filingStatus: "single", ordinaryIncome: 200000, totalAssets: 1200000, volatility: 0.45, ticker: "NVDA"}. 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 concentration_analyze: 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.
concentration_analyze 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 concentration_analyze 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 concentration_analyze. 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.
concentration_analyze 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.
