query-resources
Search, filter, and analyze Azure resources across subscriptions using Kusto Query Language (KQL) for infrastructure auditing, inventory management, and compliance checking.
Instructions
Retrieves resources and their details from Azure Resource Graph. Use this tool to search, filter, and analyze Azure resources across subscriptions. It supports Kusto Query Language (KQL) for complex queries to find resources by type, location, tags, or properties. Useful for infrastructure auditing, resource inventory, compliance checking, and understanding your Azure environment's current state.

Implementation Reference
- src/index.ts:50-81 (handler)The asynchronous handler function that implements the core logic of the 'query-resources' tool. It executes a Kusto query on Azure Resource Graph using the provided subscription ID and query string (defaulting to a basic resource list), handles the response or errors, and formats the output as MCP content.
async ({ subscriptionId, query }) => { try { const defaultQuery = "Resources | project id, name, type, location"; const queryToUse = query || defaultQuery; const resources = await rgClient.resources({ subscriptions: [subscriptionId], query: queryToUse, }); return { content: [ { type: "text", text: JSON.stringify(resources, null, 2), }, ], }; } catch (err) { return { content: [ { type: "text", text: `Error querying resources: ${ err instanceof Error ? err.message : String(err) }`, }, ], isError: true, }; } } - src/index.ts:40-49 (schema)Zod schema defining the input parameters for the 'query-resources' tool: subscriptionId (string, default from env) and optional query (string). Used for validation in the tool registration.
