search_ngsiem
Execute a CQL query against Next-Gen SIEM
Part of the CrowdStrike Falcon MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call search_ngsiem to retrieve information from CrowdStrike Falcon without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.
WHY ENFORCE A POLICY ON SEARCH_NGSIEM
Even though search_ngsiem only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
RECOMMENDED POLICY
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

FREQUENTLY ASKED QUESTIONS
What does the search_ngsiem tool do?
Execute a CQL query against Next-Gen SIEM. It is categorised as a Read tool in the CrowdStrike Falcon MCP Server, which means it retrieves data without modifying state.
How do I enforce a policy on search_ngsiem?
Add a rule in your Intercept YAML policy under the tools section for search_ngsiem. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the CrowdStrike Falcon MCP server.
What risk level is search_ngsiem?
search_ngsiem is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit search_ngsiem?
Yes. Add a rate_limit block to the search_ngsiem rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
How do I block search_ngsiem completely?
Set action: deny in the Intercept policy for search_ngsiem. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
What MCP server provides search_ngsiem?
search_ngsiem is provided by the CrowdStrike Falcon MCP server (falcon-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
