Tools (5)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

cybersec_get_prompt
Get a specific prompt by id, with optional variable substitution. Returns the full prompt text ready to send to an LLM. Variables not provided remain as [PLACEHOLDERS] in the output and are listed under unfilledVariables.
cybersec_get_scenario
Get a complete scenario workflow with every step expanded (phase, description, prompt text). Variables are substituted across all steps. Use this when the user describes a full engagement (incident, audit, hunt) rather than a single task.
cybersec_list_categories
List the 8 cybersecurity prompt categories with descriptions and prompt counts. Call this first to see what domains are covered before listing or fetching specific prompts.
cybersec_list_prompts
Search and filter the prompt library. Returns prompt summaries (id, title, useWhen, variables) — up to 50 per call. Follow up with cybersec_get_prompt for the full text.
cybersec_list_scenarios
List all 7 scenario workflows — multi-step prompt chains for complete engagements (incident response, pentest, cloud audit, etc.). Each scenario takes variables and walks through chained phases.
