Implementation Reference

  • The handler function for the 'check_SMB_signing' tool. It takes a list of IP addresses and runs the 'netexec smb' command on them to check SMB signing status.
    def check_SMB_signing(ips:List[str]):
        return run_command(["netexec","smb"]+ips)
  • Registers the 'check_SMB_signing' tool in the MCP server using the @mcp.tool decorator.
    @mcp.tool(name="check_SMB_signing",description="used to check smb signgings of an ip address or some range of ip addresses with the needed options")
Behavior2/5

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 vaguely describes behavior as 'checking' with 'options', but doesn't disclose critical traits like whether it's read-only, destructive, requires authentication, has rate limits, or what the output looks like. For a network security tool with no annotations, this is a significant gap in 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 is a single run-on sentence with typos ('signgings'), making it somewhat unclear. It's front-loaded with the core purpose but could be more structured. While concise in length, the lack of clarity reduces its effectiveness, placing it at an average level.

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?

Given no annotations, no output schema, and low schema coverage (0%), the description is incomplete. It doesn't cover behavioral aspects, parameter details, or expected results. For a tool in a security context with siblings like network scanners, more context is needed to guide an agent effectively.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate. It mentions 'ip address or some range of ip addresses' and 'needed options', which loosely relates to the 'ips' parameter (an array of strings). However, it doesn't explain parameter semantics, such as format (e.g., CIDR, single IPs), what 'options' entail, or any constraints. This adds minimal value beyond the bare schema.

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

Purpose2/5

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

The description states the tool checks 'smb signgings' (likely SMB signing) for IP addresses or ranges, which gives a basic purpose. However, it's vague about what 'checking' entails (e.g., verification, enumeration, or testing) and doesn't differentiate from siblings like 'spider_smb_shares' or 'run_nmap_scan', which might involve similar network scanning. It avoids tautology by not just restating the name, but lacks 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?

The description mentions checking IPs with 'needed options', implying some context, but provides no explicit guidance on when to use this tool versus alternatives. For example, it doesn't compare to 'run_nmap_scan' for network scanning or 'spider_smb_shares' for SMB-related tasks. There's no mention of prerequisites, exclusions, or specific scenarios, leaving usage unclear.

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