Query Excalidraw elements with optional filters
AI agents call query_elements to retrieve information from Excalidraw MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or inspects diagram elements from the canvas without creating, modifying, deleting, or executing external operations. It is purely informational and poses minimal risk if misused by an AI agent, as the worst outcome would be unnecessary queries consuming resources or exposing non-sensitive diagram structure.
From the tool's definition Tool name 'query_elements' and description 'Query Excalidraw elements with optional filters' indicate a retrieval operation with no side effects. The word 'query' paired with 'optional filters' describes a read-only inspection capability.

Query Excalidraw elements with optional filters. It is categorised as a Read tool in the Excalidraw MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Excalidraw MCP Server MCP server in PolicyLayer and add a rule for query_elements: 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 Excalidraw MCP Server. Nothing to install.
query_elements 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 query_elements 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 query_elements. 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.
query_elements is provided by the Excalidraw MCP Server MCP server (kakacoding1/mcp_excalidraw). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
