What check_url_phishing does on Tanod
AI agents call check_url_phishing to retrieve information from Tanod 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 |
|---|---|---|---|
url | object | — | URL, host or domain to screen (at most 2,048 characters); only parsed, never fetched. |
domain | object | — | Alternative to url: a domain or host name. |
Parameters from the server's own tool schema.
Why check_url_phishing is rated Low
Even though check_url_phishing 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.
Risk signalsAccepts URL/endpoint input (url)
Attacks that exploit this kind of access
The rule that runs check_url_phishing safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Tanod, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For check_url_phishing, this is the rule to start with:
check_url_phishing 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 Tanod, apply this rule, and every check_url_phishing call is checked against it from then on.
Questions about check_url_phishing
chainpeek: Check if a URL or domain is phishing or a scam. For up to 1,000 URLs use check_urls_phishing_batch; for headers use check_security_headers. Returns whether a URL's host (or a domain) is on public phishing/scam domain lists: listed, the matched_domain, the sources that list it and shared_platform, with the lists' update time and a disclaimer. A screening aid: the host and its parent domains are matched against two public lists, PhishDestroy (CC0) and Phishing.Database (MIT), refreshed daily; the URL is never fetched. An unlisted host is not cleared: new phishing is on no list yet, and lists can be stale. Input that is not a URL, host or domain is a 422 invalid_input (not charged). Typically under 0.1 s (first call up to a few seconds). Price: USD 0.001. Free: 10 chain reads per IP per UTC day. The submitted text is never logged or stored. Docs: https://tanod.dev/learn/phishing-scam-url-checker-api.html. It is categorised as a Read tool in the Tanod MCP Server, which means it retrieves data without modifying state.
check_url_phishing accepts 2 parameters: url, domain. The full parameter table on this page comes from the server's own tool schema.
Register the Tanod MCP server in PolicyLayer and add a rule for check_url_phishing: 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 Tanod. Nothing to install.
check_url_phishing 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 check_url_phishing 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 check_url_phishing. 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.
check_url_phishing is provided by the Tanod MCP server (https://tanod.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
