What depreciation does on ScorpTech x402 API
AI agents call depreciation to retrieve information from ScorpTech x402 API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
cost | number | Yes | Asset cost (basis) |
method | string | — | |
salvage | number | — | Salvage value (ignored by MACRS) |
dbFactor | number | — | declining-balance factor (2 = double) |
lifeYears | integer | Yes | Useful life; for MACRS the recovery class 3, 5, 7, 10, 15 or 20 |
switchToStraightLine | boolean | — | Declining balance: switch to straight-line when it gives more |
Parameters from the server's own tool schema.
Why depreciation is rated Low
Even though depreciation only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs depreciation safely
PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For depreciation, this is the rule to start with:
depreciation is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every depreciation call is checked against it from then on.
Questions about depreciation
Depreciation schedules: straight-line, declining balance (any factor, optional switch to straight-line), double-declining, sum-of-the-years-digits and US MACRS GDS (3/5/7/10/15/20-year, half-year convention, computed from the IRS rules: 200% or 150% DB switching to straight-line). Year-by-year depreciation, accumulated depreciation and book value. Price: $0.002 USDC per successful call (x402, Solana). Same tool over HTTPS: GET https://scorptech.it.com/api/x402/v1/depreciation. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.
depreciation accepts 6 parameters: cost, method, salvage, dbFactor, lifeYears, switchToStraightLine. Required: cost, lifeYears. The full parameter table on this page comes from the server's own tool schema.
Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for depreciation: 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 ScorpTech x402 API. Nothing to install.
depreciation 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 depreciation 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 depreciation. 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.
depreciation is provided by the ScorpTech x402 API MCP server (https://scorptech.it.com/api/x402/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
