MCP Azure DevOps 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 effectively describes what the tool does (retrieves iterations), explains the Azure DevOps context, and specifies the return format (formatted string as markdown). However, it doesn't mention potential limitations like authentication requirements, rate limits, or error conditions.

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 well-structured with clear sections: purpose statement, usage guidelines, important context, parameters, and return value. Every sentence adds value without redundancy. The bulleted lists make it scannable while maintaining completeness.

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 tool with 3 parameters, no annotations, and no output schema, the description provides excellent coverage of purpose, usage, parameters, and return format. The only minor gap is the lack of explicit behavioral constraints (like authentication or error handling), but given the tool's read-only nature and clear parameter documentation, it's mostly complete.

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?

With 0% schema description coverage, the description fully compensates by providing detailed parameter documentation in the Args section. It explains each parameter's purpose (project_name_or_id, team_name_or_id, current), including the special behavior of the 'current' parameter ('If True, return only the current iteration'). This adds significant value beyond the bare schema.

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 ('Retrieves the iterations') and resource ('assigned to a specific team'), distinguishing it from sibling tools like get_all_teams or get_team_members. It explicitly mentions Azure DevOps context and what iterations represent, providing clear 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?

The description provides explicit usage scenarios in a bulleted list ('View a team's sprint schedule', 'Find date ranges for iterations', etc.), giving clear guidance on when to use this tool. It also explains the importance of iterations in Azure DevOps, helping the agent understand the context for application.

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