Implementation Reference
- src/tools/mesh.ts:272-279 (handler)Handler logic for the 'bulc_modify_mesh' tool. Validates the input arguments using ModifyMeshSchema and sends a 'modify_mesh' command to the BULC client via sendCommand.
case "bulc_modify_mesh": { const validated = ModifyMeshSchema.parse(args); result = await client.sendCommand({ action: "modify_mesh", params: validated, }); break; } - src/tools/mesh.ts:218-229 (schema)Zod validation schema for the input parameters of the 'bulc_modify_mesh' tool.
const ModifyMeshSchema = z.object({ meshId: z.string(), xMin: z.number().optional(), xMax: z.number().optional(), yMin: z.number().optional(), yMax: z.number().optional(), zMin: z.number().optional(), zMax: z.number().optional(), iCells: z.number().int().positive().optional(), jCells: z.number().int().positive().optional(), kCells: z.number().int().positive().optional(), }); - src/tools/mesh.ts:120-174 (registration)MCP tool registration for 'bulc_modify_mesh', including name, description, input schema (JSON schema), and annotations. Part of the exported meshTools array.
