Check BIMI (Brand Indicators for Message Identification) and VMC (Verified Mark Certificate) for a domain. Returns BIMI DNS record status, VMC certificate details, logo URL, trademark info, and expiry.
| Name | Required | Description | Default |
|---|---|---|---|
| domain | Yes | Domain name to check BIMI/VMC for (e.g. google.com) |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. 'Check' implies a read-only operation, and the description discloses what is returned, but it does not mention potential limitations, error scenarios, or any permissions/rate limits. This is adequate but not rich.
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 a single sentence, front-loaded with the action, and lists return values efficiently. No redundant or filler content.
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 single-parameter tool with no output schema, the description is fairly complete. It names the specific return items (DNS status, VMC details, logo URL, trademark info, expiry) and the input domain. Minor gaps like error handling or prerequisites are not critical here.
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?
Schema coverage is 100% with a descriptive 'domain' parameter. The description repeats 'domain' but adds no extra parameter semantics beyond what the schema already provides. Baseline 3 applies.
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 description clearly states the tool 'Check BIMI and VMC for a domain' with specific verb and resource, and lists return values. However, it does not explicitly distinguish itself from sibling tool 'bimi_check' or other DNS/SSL tools, so it lacks sibling differentiation.
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?
No guidance is provided on when to use this tool versus alternatives like 'bimi_check' or 'ssl_certificate'. The description only states what it does, not context or exclusions.
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.
Tools have mostly distinct purposes, e.g., dns_lookup vs dns_record vs dns_propagation are different operations. A few overlaps like bimi_check versus bimi_vmc and dns_lookup versus dns_record could cause slight confusion, but descriptions are clear enough.
All tools use snake_case with consistent verb_noun pattern (e.g., dns_lookup, bimi_check, uptime_check). The my_* prefix for account-specific tools provides a clear sub-pattern. No mixed conventions.
23 tools is somewhat high but justified for a DNS/domain monitoring server covering lookups, health checks, security, SSL, RDAP, BIMI, uptime, and account management. Each tool adds distinct value, though a few could be merged.
Covers DNS, SSL, security, hosting, BIMI, RDAP, and account monitoring comprehensively. Minor gaps: no direct WHOIS (RDAP covers registration) and no DNS record modification tools (read-only focus). Overall well-rounded.
