Rubeus MCP Server

rubeus_monitor

Watch for new Kerberos TGT events and display them as they occur, without harvesting or renewing tickets.

Instructions

Monitor for new TGTs without harvesting/renewal.

Watches for new TGT events and displays them as they occur. Lighter weight than harvest - just observation.

Input Schema

TableJSON Schema

intervalNoCheck interval (seconds, default 60)
targetuserNoOnly monitor specific user
nowrapNoDon't wrap base64 output
registryNoStore tickets in registry
runforNoRun for specified duration (seconds)
Behavior3/5

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

No annotations provided, so description must bear full burden. Says 'just observation' implying read-only, but does not explicitly disclose if it modifies state, requires privileges, or what happens on interval completion. Adequate but not fully explicit.

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?

Efficient two-sentence description that is front-loaded with primary purpose. No wasted words.

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?

Given no output schema, description explains real-time display behavior. Could mention continuous monitoring until 'runfor' expires, but parameter covers duration. Largely complete for a monitoring tool.

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%, so baseline 3. Description does not add any extra meaning to parameters; the schema already describes each parameter adequately.

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 it monitors for new TGT events, distinguishes from harvest by being lightweight and observation-only. Gives specific verb 'monitor' and resource 'new TGTs'.

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?

Provides clear context that it is for observation without harvesting/renewal, implying use when only monitoring is needed. But does not explicitly state when not to use or list alternatives beyond harvest.

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