Changes observed during successful MCP inspections.
v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The word 'Check' implies a read-only, non-mutating operation, which is useful behavioral information in the absence of annotations. However, the description does not disclose what happens after the check, whether any endpoint is contacted, or what the output represents beyond 'available updates.'
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?
A single clear sentence with no redundancy. It front-loads the action and immediately states the scope. Every word earns its place.
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 no-parameter, no-output-schema tool, the description is mostly sufficient: it names the operation and the scope. It could be improved by noting whether the tool only lists updates or performs any additional actions, but this is a minor gap given the simple signature.
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 tool has zero parameters, so there is no parameter documentation burden. The description accurately reflects the tool's scope without needing to explain any inputs.
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 states a specific verb ('Check') and a clear resource ('available firmware updates'), and scopes it to 'across all devices.' This clearly differentiates it from sibling tools like get_network_status or get_device_details, which target different resources.
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?
No guidance is provided about when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or any sibling tool that might also seem relevant, such as get_device_details or list_devices.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
