FlexSim MCP Server

webserver_status

Checks whether the FlexSim WebServer is online before model operations and reports status so users can start it if offline.

Instructions

A4.6/5.0

Behavior4/5

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

With no annotations, the description carries the burden and does reasonably well: it discloses the dependency relationship between the WebServer and every model operation, and tells the agent what to do on a negative result. It stops short of stating that the call itself is a side-effect-free query or what exact value a negative result yields, which is the only remaining gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with the purpose and followed by the sequential prerequisite and fallback. No redundant restatement of the tool name and nothing that could be cut.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter status probe with no output schema, the description covers purpose, prerequisite ordering and the failure branch, which is nearly everything an agent needs. The only omission is the shape of the returned status value, which matters slightly more because there is no output schema to fall back on.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so the baseline is 4. There is nothing for the description to disambiguate, and it correctly does not waste words on nonexistent inputs.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource — checking whether the FlexSim WebServer is online — and implicitly distinguishes the tool from the sibling start_webserver, which is named as the action to take when the check fails. An agent can identify the tool's role without inspecting the empty schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicit when-to-use guidance is given: check before any model operation because all of them depend on the WebServer. It also supplies an explicit alternative path — call start_webserver if it is not online — so both the positive and negative branches are resolved.

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