List all domains on this account's trusted allowlist.
Allowlisted domains suppress the compound signal and brand impersonation floor in scoring. The full pipeline still runs — all signals remain visible for monitoring. Use this to see which domains are currently trusted.
Returns the list of domains, current count, and the 1,000-domain limit.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already convey read-only, idempotent, non-destructive behavior. The description adds valuable context: allowlisted domains suppress the compound signal and brand impersonation floor, the full pipeline still runs, and monitoring remains possible. It also discloses return contents (list, count, limit). No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three short sentences with the core purpose front-loaded. Every sentence earns its place, providing meaningful context without excess.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple, zero-parameter read-only tool, the description fully covers what it returns (list, count, limit), the behavioral effect of allowlisting, and the fact that it is a read operation. No output schema is needed because the return values are described.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are zero parameters, so the baseline of 4 applies. The description correctly omits parameter details since none exist.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The verb 'List' and resource 'all domains on this account's trusted allowlist' make the purpose unambiguous. It clearly distinguishes from sibling tools like add_to_allowlist and list_profiles.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states 'Use this to see which domains are currently trusted' and explains the context of allowlisting effects. It does not mention when not to use it or alternatives, but the sibling names and the specificity of the description make the use case clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have clearly distinct purposes: check_url vs check_urls distinguish single vs batch, allowlist CRUD tools are separated, and profile management is distinct from account billing. Minor overlap exists between get_balance and get_stats (both report balance) and between list_profiles and show_defaults (both relate to scoring configuration), but descriptions clarify the differences.
The vast majority of tools follow a verb_noun snake_case pattern (check_url, create_profile, list_allowlist, get_balance). A few outliers like purchase and signup are single verbs, but they are standard and do not break the overall predictability.
18 tools is above the ideal 3-15 range but appropriate for the server's broad scope: URL analysis, custom scoring profiles, allowlist management, account billing, and reporting. Each tool serves a distinct function and none feel redundant or superfluous.
The tool surface covers the core domain thoroughly: single and batch URL checks, credit estimation, profile CRUD (create, list, delete, show defaults), allowlist CRUD, history, and account management (signup, balance, pricing, purchase). Minor gaps exist, such as no delete history or direct retrieval of a single past check by ID, but these are not critical.
