MCP AbuseIPDB Server

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions enrichment with AbuseIPDB data but lacks details on rate limits, authentication requirements, error handling, or what the output looks like (e.g., structured data vs. raw text). This is inadequate for a tool that likely involves external API calls and data processing.

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, efficient sentence that front-loads the core purpose without unnecessary words. Every part of the sentence contributes directly to explaining what the tool does, making it highly concise and well-structured.

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?

Given the tool's complexity (involving external API data enrichment) and lack of annotations and output schema, the description is insufficient. It doesn't cover behavioral aspects like rate limits or output format, leaving critical gaps for an AI agent to use it effectively in context with sibling tools.

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 description coverage is 100%, so the schema fully documents all parameters. The description adds no additional meaning beyond implying that 'log_line' contains IP addresses and 'threshold'/'max_age_days' relate to AbuseIPDB filtering. This meets the baseline for high schema coverage but doesn't enhance understanding.

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 specific action ('Extract and enrich'), the target resource ('IP addresses from a log line'), and the data source ('with AbuseIPDB data'). It distinguishes itself from sibling tools like 'check_ip' or 'bulk_check' by focusing on log line processing rather than direct IP checking or bulk operations.

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 provides no guidance on when to use this tool versus alternatives like 'check_ip' for single IPs or 'bulk_check' for multiple IPs. It doesn't mention prerequisites, such as needing AbuseIPDB access, or exclusions, like whether it handles IPv6 addresses or specific log formats.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
