Windows Operations MCP

windows_network

List, add, or delete Windows firewall rules, and diagnose network connectivity issues using netsh/PowerShell commands.

Instructions

Perform Windows networking and firewall operations with specialized orchestration.

RATIONALE: Consolidates complex 'netsh' and PowerShell networking commands into a single portmanteau. Enables autonomous security auditing and perimeter hardening.

Args: action: The networking operation to perform. rule_name: Name of the firewall rule. rule_dir: Direction of the traffic (in/out). rule_action: Action (allow/block). rule_program: Path to the executable (for firewall_add). rule_port: Local port number (for firewall_add). ctx: FastMCP Context for telemetry and sampling.

Behavior2/5

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

No annotations are provided, so the description bears full responsibility. It mentions consolidating netsh/PowerShell commands but does not disclose behavioral traits like system impact, required permissions (e.g., admin rights), or side effects (e.g., rules persistence). For a tool that can add/delete firewall rules, this is insufficient transparency.

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

Conciseness3/5

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

The description includes a RATIONALE section that provides context but is verbose and not strictly necessary. The Args list helps structure parameter info, but overall length could be reduced. Each sentence adds some value, but the RATIONALE and telemetry mention could be condensed.

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?

Given the 6 parameters and no annotations, the description covers actions and key parameters but lacks details on return format (output schema exists but not described) and behavior for each action. For a networking tool, it misses crucial info like privilege requirements, error handling, or network impact. Moderate completeness.

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 0%, but the description lists parameter purposes for action, rule_name, rule_dir, rule_action, rule_program, rule_port. However, it doesn't add semantics beyond what the schema provides (e.g., enum values, default for rule_dir/action). The description partially compensates for lack of schema 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 states the tool performs Windows networking and firewall operations, listing specific actions like firewall_list, firewall_add, firewall_delete, and diag. This provides clear verb and resource identification, but it doesn't differentiate it from siblings like 'windows_services' or 'system_management', which are distinct enough to avoid confusion. The RATIONALE section adds context but is not critical for purpose.

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 implies usage for networking and firewall tasks via netsh and PowerShell, but lacks explicit guidance on when to use versus alternatives. No exclusions or alternative tools are mentioned. The RATIONALE hints at security auditing and perimeter hardening, but this is generic.

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