Implementation Reference
- server.py:55-62 (handler)The main handler function for the 'lookup-observable' tool. It lazily initializes a security_cli Action and calls its enrich method on the input value (observable).async def lookup(value: str) -> str: from security_cli.action import Action if not enrichmentmcp: enrichmentmcp = Action() return enrichmentmcp.enrich(value)
- server.py:65-69 (registration)Registers the 'lookup' function as the MCP tool named 'lookup-observable' with a description.mcp.add_tool( lookup, name="lookup-observable", description="A generic tool which takes any observable and passes it the correct tool.", )
- server.py:38-51 (registration)Registers a prompt named 'lookup-observable' with argument schema for 'observable' and a default prompt generator function.mcp.add_prompt( Prompt( name="lookup-observable", description="A simple security prompt for observable lookup", arguments=[ PromptArgument( name="observable", description="A observable to enrich", required=True, ) ], fn=get_default_prompt ) )
- server.py:23-34 (helper)Helper function that generates a default prompt for observable enrichment analysis, used by the registered prompt.def get_default_prompt(observable: str) -> str: return f""" As a security analyst, detection engineer and network security engineer you are responsible for making a risk level determination of one or more provided observables. Using your knowledge from these diverse fields, networking constructs, detection (security) reasoning, and responses from third-party enrichment services. Carefully consider the output from these services along with historical knowledge both internal and external from an organization to make a determination of the risk of a provided observable. Make a determination based on all these factors on whether the observable is benign, suspicious, malicious, unknown. If unknown provide suggestions for other relative context that may be needed in order to make the determination. Your objective is to assist with the threat determination of a given observable. The observable is {observable} """
