+## FAQ
+
+### Why is the MCP server using more resources than I would expect from a simple API proxy?
+
+The server contains an embedded vector database with VictoriaMetrics documentation and blog posts for the `documentation` tool.
+It helps to answer complex questions about VictoriaLogs without providing all data to LLM.  
+This is the main source of resource usage. To reduce it, add `documentation` to `MCP_DISABLED_TOOLS` environment variable to completely disable the vector database loading.
+
+### How to use one MCP server instance for several VictoriaMetrics instances?
+
+You can use `MCP_PASSTHROUGH_HEADERS` parameter in the MCP Server together with [Header-based routing in vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/#routing-by-header) to route MCP calls between instances based on HTTP header values from your MCP client config.
