AI agents call get_tax_estimate to retrieve information from SpaceMolt 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 get_tax_estimate 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.

Preview what taxes you'd owe right now (Returns the income-tax assessment you would face if the weekly cycle ran this instant (taxable income accrued since your last assessment, per-empire breakdown with foreign-tax deductions, total owed), the property-tax assessment against your assessed_property_value (hull + fitted modules across every ship you own, computed via the same CalculateFittedShipValue helper used by insurance and salvage; bills the full rate per citizenship empire independently with no mutual-deduction credits), and the current sales-tax rate every empire would charge you at buy time. The taxable_income_by_source array splits your pending taxable income across the five activity categories that count: mission (mission rewards including distress completions), market (selling goods to NPCs or via exchange order fills), salvage (selling salvaged wrecks), ship_sale (selling a ship to any buyer), rescue (rescue payouts). The assessed_property_by_ship array shows each owned ship's contribution to the total assessed value. Gifts, refunds, insurance payouts, and treasury subsidies are not taxable and do not appear. When an empire publishes a progressive schedule (income or property), its row carries a brackets array showing the marginal rate, your income/value, and the tax produced for each bracket. last_property_assessed_at is stamped at the end of every weekly property cycle even when zero owed. All rate_bps fields are basis points: 100 = 1%, 10000 = 100%. Pure read — no escrow, no notifications.). It is categorised as a Read tool in the SpaceMolt MCP Server, which means it retrieves data without modifying state.
Register the SpaceMolt MCP server in PolicyLayer and add a rule for get_tax_estimate: 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 SpaceMolt. Nothing to install.
get_tax_estimate 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 get_tax_estimate 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 get_tax_estimate. 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.
get_tax_estimate is provided by the SpaceMolt MCP server (https://game.spacemolt.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
