TDQS

B3/5.0
Behavior2/5

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

With no annotations provided, the description carries the full burden of disclosing behavior. It gives examples but does not mention return values, exit codes, error handling, side effects, environment specifics, or security implications. For a command execution tool, this is insufficient.

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

Conciseness4/5

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

The opening one-sentence description is concise and front-loaded. The three examples are redundant in structure but serve to illustrate cross-shell syntax. Each sentence earns its place, though the examples could be trimmed to one or two without loss.

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

Completeness2/5

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

For a tool that executes arbitrary system commands, there is no mention of output format, timeouts, working directory defaults, or safety considerations. The presence of sibling ssh_execute suggests a need to clarify local vs remote execution, which is absent. The examples help but do not fill all gaps.

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 schema already covers 100% of parameters, but the description adds value through concrete examples showing valid shell values, command syntax, and workingDir formatting (e.g., Windows paths vs Git Bash paths). This enhances understanding beyond the schema's terse descriptions.

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

Purpose4/5

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

The description clearly states the tool executes a command in a specified shell (powershell, cmd, or gitbash), which is a specific verb+resource. It is distinguishable from siblings like get_command_history and ssh_execute, though it does not explicitly call out these differences. The mention of the shell options adds specificity.

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

Usage Guidelines2/5

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

No guidance is given on when to use this tool versus alternatives such as ssh_execute (remote execution) or get_command_history. The examples imply usage but do not provide context, prerequisites, or exclusions. This is a clear gap.

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

get_command_historyA

Get the history of executed commands

Example usage:

{
  "limit": 5
}

Example response:

[
  {
    "command": "Get-Process",
    "output": "...",
    "timestamp": "2024-03-20T10:30:00Z",
    "exitCode": 0
  }
]
ParametersJSON Schema
NameRequiredDescriptionDefault
limitNoMaximum number of history entries to return (default: 10, max: 1000)

TDQS

A4/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden. It adds transparency by showing a detailed example response with fields (command, output, timestamp, exitCode), which clarifies the return format. However, it does not explicitly state whether history is session-scoped, how results are ordered, or that it has no side effects. Given the absence of annotations, there are notable but not critical gaps.

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?

The description is concise: a single opening sentence plus two compact JSON examples. The purpose is front-loaded, and every element adds value—the example usage demonstrates the parameter, and the example response shows the expected output structure. No redundancy or filler.

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 simple one-parameter, no-output-schema tool, the description is quite complete: it states the purpose, shows how to invoke it, and provides a representative response. Minor omissions like ordering or session scope are not critical for a list-history tool. The example response effectively substitutes for an output schema, making the tool actionable for an agent.

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

Parameters3/5

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

The input schema already fully documents the 'limit' parameter with default (10) and max (1000) values, providing 100% coverage. The description's example usage (limit: 5) reinforces the parameter but adds no new semantic meaning beyond the schema. Baseline 3 is appropriate because the schema does the heavy lifting.

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 opens with a clear verb+resource statement: 'Get the history of executed commands'. It distinguishes itself from sibling tools like execute_command (execution) and ssh_execute (remote execution) by focusing specifically on retrieval of prior commands. The example response reinforces the purpose.

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

Usage Guidelines4/5

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

The description provides a clear usage context: to retrieve previously executed commands, with an example showing the optional limit parameter. It does not explicitly state when not to use it, but the purpose is self-evident and no competing history tools exist among siblings. No explicit exclusions are given, but this is clearly a read-only counterpart to the execution siblings.

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

ssh_disconnectA

Disconnect from an SSH server

Example usage:

{
  "connectionId": "raspberry-pi"
}

Use this to cleanly close SSH connections when they're no longer needed.

ParametersJSON Schema
NameRequiredDescriptionDefault
connectionIdYesID of the SSH connection to disconnect

TDQS

A3.9/5.0
Behavior3/5

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

With no annotations, the description must carry the full burden. It mentions 'cleanly close' but doesn't disclose side effects like what happens to associated sessions, idempotency, or error behavior. It's minimally adequate but not rich.

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

Conciseness4/5

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

The description is short and includes a practical JSON example, which helps the agent. It repeats the concept slightly ('Disconnect' and 'close SSH connections'), but overall it's well-structured and efficient.

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 simple one-parameter tool with no output schema, the description is adequate. It provides an example and clear use case. It doesn't cover errors or edge cases, but given the low complexity, this is not a significant gap.

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

Parameters3/5

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

Schema coverage is 100% with the parameter described as 'ID of the SSH connection to disconnect'. The example usage adds an illustrative value (raspberry-pi) but doesn't add semantic meaning beyond the schema, so baseline 3 applies.

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 clearly states the verb 'Disconnect' and the resource 'SSH connection/server', which distinguishes it from siblings like ssh_execute and execute_command. The example usage reinforces the exact action.

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

Usage Guidelines4/5

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

It says 'when they're no longer needed', providing clear context for when to use this tool. It doesn't explicitly mention alternatives or when not to use, but the sibling tool names imply the distinction, so a slight deduction is warranted.

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

ssh_executeA

Execute a command on a remote host via SSH

Example usage:

{
  "connectionId": "raspberry-pi",
  "command": "uname -a"
}

Configuration required in config.json:

{
  "ssh": {
    "enabled": true,
    "connections": {
      "raspberry-pi": {
        "host": "raspberrypi.local",
        "port": 22,
        "username": "pi",
        "password": "raspberry"
      }
    }
  }
}
ParametersJSON Schema
NameRequiredDescriptionDefault
connectionIdYesID of the SSH connection to use
commandYesCommand to execute

TDQS

A3.8/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden. It mentions that SSH must be enabled in config.json and gives an example connection, which is useful. However, it does not disclose the command execution behavior (e.g., output format, error handling, potential destructive side-effects) or that it uses the specified password for authentication.

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

Conciseness4/5

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

The description is structured and efficient, with a one-sentence purpose followed by illustrative JSON examples. The config block is large but necessary to show the setup requirements. No wasted words.

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

Completeness3/5

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

With no output schema and no annotations, the description should explain what the tool returns or what 'execute' entails. It does neither, though it does provide configuration context. For a command execution tool, the lack of mention of output or error behavior leaves a moderate gap.

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 input schema descriptions are minimal ('Command to execute', 'ID of the SSH connection to use'). The description adds meaningful value by showing an example usage and the config structure, clarifying that connectionId refers to a key in the 'connections' object and command is a shell string.

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 clearly states 'Execute a command on a remote host via SSH', using a specific verb and resource. It distinguishes itself from sibling tools like ssh_disconnect (manage connection) and get_command_history (retrieve history).

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

Usage Guidelines3/5

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

The description provides a concrete example and configuration requirement, implying when to use the tool (when you have a configured SSH connection and need to run a command). However, it does not explicitly state when to use it over alternatives like execute_command, nor does it provide exclusion criteria.

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

B3.1/5.0

Scored across 4 tools

Disambiguation3/5

The tools have some overlap in purpose that could cause confusion. execute_command and ssh_execute both execute commands but in different contexts (local vs remote), which might lead to misselection if the agent doesn't carefully distinguish between local and remote execution. However, get_command_history and ssh_disconnect are clearly distinct from the execution tools.

Naming Consistency4/5

The naming follows a mostly consistent verb_noun pattern with clear actions like execute, get, and disconnect. All tools use snake_case consistently. The minor deviation is that ssh_disconnect uses 'disconnect' while others use more specific verbs, but overall it's readable and predictable.

Tool Count3/5

With only 4 tools, the count feels borderline thin for a 'Super Windows CLI MCP Server' that implies broader command-line capabilities. It covers basic execution and SSH operations but lacks tools for file management, process control, or other common CLI tasks, making the scope seem underdeveloped.

Completeness2/5

There are significant gaps in the tool surface for a Windows CLI server. It includes command execution and SSH operations but misses core functionalities like file operations (e.g., copy, move, delete), process management (e.g., start, stop), system information retrieval, or network utilities. The SSH tools are incomplete without a corresponding ssh_connect tool to establish connections.
