List Microsoft Sentinel parsers (KQL functions) - search by solution, name, query content, or file path. Returns max 100 results by default.
AI agents call list_parsers to retrieve information from Sentinel Solutions MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
list_parsers queries and retrieves parser metadata (KQL functions) from a Sentinel index. It performs searches across solution, name, query content, and file path but does not execute queries, modify data, delete content, or create financial obligations. This is a standard read/query operation with no side effects.
From the tool's definition Tool lists Microsoft Sentinel parsers with search capabilities and 'Returns max 100 results' — purely retrieval with no modification or execution of data.
Attacks that exploit this kind of access
List Microsoft Sentinel parsers (KQL functions) - search by solution, name, query content, or file path. Returns max 100 results by default. It is categorised as a Read tool in the Sentinel Solutions MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sentinel Solutions MCP Server MCP server in PolicyLayer and add a rule for list_parsers: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Sentinel Solutions MCP Server. Nothing to install.
list_parsers is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_parsers rule in your PolicyLayer 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.
Set action: deny in the PolicyLayer policy for list_parsers. 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.
list_parsers is provided by the Sentinel Solutions MCP Server MCP server (noodlemctwoodle/sentinel-solutions-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
