MCP Web Scrape

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

No annotations are provided, so the description carries full burden. It mentions analysis for 'SEO and content insights' but lacks details on behavioral traits such as rate limits, authentication needs, whether it performs web scraping or uses APIs, what happens with cached data, or the format of returned insights. The description is too vague for a tool that likely involves external data fetching.

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 with no wasted words. It's front-loaded with the core purpose and uses clear, direct language appropriate for a tool name like 'analyze_competitors'.

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 no annotations, no output schema, and a tool that likely performs complex web analysis (inferred from sibling tools), the description is incomplete. It doesn't cover what the analysis returns, potential limitations, error handling, or how it integrates with other tools in the server, leaving significant gaps for an AI agent.

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 already documents all parameters (urls, metrics, useCache) with descriptions and defaults. The description adds no additional parameter semantics beyond what's in the schema, maintaining the baseline score of 3.

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's purpose: 'Analyze competitor websites for SEO and content insights.' It specifies the verb ('analyze'), resource ('competitor websites'), and domain focus ('SEO and content insights'). However, it doesn't explicitly differentiate from siblings like 'analyze_page_speed' or 'benchmark_performance' that might overlap in analyzing websites.

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. With many sibling tools like 'analyze_performance', 'extract_keywords', and 'compare_content', there's no indication of specific contexts, prerequisites, or exclusions for this tool's use.

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