Implementation Reference
- src/index.js:419-440 (handler)The handler function for the 'query_elements' tool. It parses the input arguments using QuerySchema, filters the global 'elements' Map based on optional 'type' and 'filter' parameters, and returns the matching elements as a JSON string in the tool response content.
case 'query_elements': { const params = QuerySchema.parse(args || {}); const { type, filter } = params; let results = Array.from(elements.values()); if (type) { results = results.filter(element => element.type === type); } if (filter) { results = results.filter(element => { return Object.entries(filter).every(([key, value]) => { return element[key] === value; }); }); } return { content: [{ type: 'text', text: JSON.stringify(results, null, 2) }] }; } - src/index.js:155-170 (registration)Registration of the 'query_elements' tool in the MCP server capabilities object, defining its description and input schema for tool discovery.
query_elements: { description: 'Query Excalidraw elements with optional filters', inputSchema: { type: 'object', properties: { type: { type: 'string', enum: Object.values(EXCALIDRAW_ELEMENT_TYPES) }, filter: { type: 'object', additionalProperties: true } } } }, - src/index.js:70-73 (schema)Zod validation schema (QuerySchema) used internally in the 'query_elements' handler to parse and validate input parameters.
const QuerySchema = z.object({ type: z.enum(Object.values(EXCALIDRAW_ELEMENT_TYPES)).optional(), filter: z.record(z.any()).optional() });
