Sentinel Solutions MCP Server

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the default limit of 100 results, which is useful, but doesn't address critical aspects like whether this is a read-only operation, potential rate limits, authentication requirements, error conditions, or pagination behavior. For a tool with 8 parameters, this leaves significant behavioral gaps.

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 efficiently structured in a single sentence that front-loads the core purpose. Every element serves a purpose: stating the action, resource, search parameters, and default limit. It could potentially be slightly more structured by separating search parameters from behavioral constraints, but it remains highly efficient.

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 (8 parameters, no annotations, no output schema), the description provides basic but incomplete coverage. It explains the core functionality and some behavioral constraints but lacks details about return format, error handling, authentication needs, and how to interpret results. For a list operation with multiple filtering options, more context would be helpful.

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 8 parameters. The description adds some context by mentioning three search parameters ('search by solution, name, or file path') and the limit parameter's default, but doesn't provide additional semantic meaning beyond what's in the schema. This meets the baseline expectation when schema coverage is complete.

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 action ('List Microsoft Sentinel watchlists') and resource ('watchlists'), making the purpose immediately understandable. However, it doesn't explicitly differentiate this tool from other list_* siblings in the server, which prevents a perfect score.

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 mentions search capabilities ('search by solution, name, or file path') and a default limit ('Returns max 100 results by default'), but provides no guidance on when to use this tool versus alternatives like other list_* tools or search_solutions. There's no mention of prerequisites, typical use cases, or exclusion criteria.

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