CData Sync MCP 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 adds context beyond the input schema: it details user roles (e.g., 'cdata_admin'), return types (list, get, count), and common errors with explanations (e.g., 'Access denied' requires admin role). This covers key behavioral aspects like permissions and error handling, though it could mention rate limits or pagination.

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 structured with sections (ROLES, RETURNS, COMMON ERRORS), which aids readability, but it's somewhat verbose and could be more front-loaded. Sentences like 'Access CData Sync user accounts and their permissions' are clear, but the detailed lists and error explanations add bulk without always being essential. It's adequately sized but not optimally concise.

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 (7 parameters, no annotations, no output schema), the description does a good job of adding context. It covers roles, return types, and errors, which compensates for the lack of annotations and output schema. However, it could be more complete by explicitly stating it's a read-only tool or mentioning sibling tools, but overall it's fairly comprehensive for the given context.

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?

The schema description coverage is 100%, so the schema already documents all 7 parameters thoroughly. The description adds no parameter-specific information beyond what's in the schema. However, it implies the tool's actions (list, get, count) and roles, which loosely relate to parameters like 'action' and 'filter', but doesn't provide additional syntax or usage details. Baseline 3 is appropriate as the schema does the heavy lifting.

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 as 'Access CData Sync user accounts and their permissions,' which is a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'write_users' or other 'read_' tools, though the 'Access' verb implies read-only operations. The purpose is clear but 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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'write_users' or other 'read_' tools, nor does it specify prerequisites or contexts for usage. The 'COMMON ERRORS' section hints at admin requirements but doesn't offer proactive usage advice.

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