WHAT IT DOES

What totp does on ScorpTech x402 API

AI agents use totp to create or update resources in ScorpTech x402 API, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ScorpTech x402 API environment.

Parameter	Type	Required	Description
`uri`	string	—	parse-uri: otpauth://totp/... or otpauth://hotp/...
`code`	string	—	verify: the code to check
`mode`	string	—
`time`	integer	—	Unix time (default: now)
`bytes`	integer	—	new-secret: secret length in bytes
`digits`	integer	—
`issuer`	string	—
`period`	integer	—
`secret`	string	—	Base32 shared secret (spaces / lowercase OK)
`window`	integer	—	verify: steps accepted either side
`account`	string	—	Account label for the otpauth URI, e.g. alice@example.com
`counter`	integer	—	HOTP counter (switches to HOTP)

Parameters from the server's own tool schema.

RISK

Why totp is rated Medium

An AI agent can call totp faster than any human can review: one bad instruction and it creates or modifies resources in ScorpTech x402 API by the hundred, each call as confident as the last.

Risk signalsAccepts freeform code/query input (code) · Accepts URL/endpoint input (uri) · Handles credentials or secrets (secret) · High parameter count (13 properties)

RECOMMENDED RULE

The rule that runs totp 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 totp, this is the rule to start with:

totp Rate-limited

totp stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every totp call is checked against it from then on.

FAQ

Questions about totp

What does the totp tool do? +

TOTP / HOTP two-factor codes (RFC 6238 / 4226), compatible with Google Authenticator, Authy, 1Password and pyotp: generate the current code (plus previous / next and seconds remaining), verify a code with a drift window, create a new base32 secret with its otpauth:// URI for QR enrolment, or parse an otpauth URI. SHA1 / SHA256 / SHA512, 6–8 digits, any period; set time for reproducible results or counter for HOTP. POST so secrets never appear in URLs; secrets are not stored. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/totp. It is categorised as a Write tool in the ScorpTech x402 API MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does totp accept? +

totp accepts 12 parameters: uri, code, mode, time, bytes, digits, issuer, period, secret, window, account, counter. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on totp? +

Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for totp: 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.

What risk level is totp? +

totp is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit totp? +

Yes. Add a rate_limit block to the totp 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.

How do I block totp completely? +

Set action: deny in the PolicyLayer policy for totp. 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.

What MCP server provides totp? +

totp 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.
