get_icon_glyph_by_style

Instructions

Implementation Reference

• src/index.ts:389-409 (handler)

  The main MCP tool handler for get_icon_glyph_by_style. It validates the input arguments, calls the getGlyphByStyle helper function, formats the response, and handles errors.

  private async handleGetIconGlyphByStyle(args: any) {
    try {
      const iconName = this.validateIconName(args);
      const style = this.validateIconStyle(args);
      const glyph = await getGlyphByStyle(iconName, style);
  
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(glyph, null, 2),
          },
        ],
      };
    } catch (error) {
      throw new McpError(
        ErrorCode.InternalError,
        `Failed to get icon glyph by style: ${error instanceof Error ? error.message : "Unknown error"}`
      );
    }
  }

• src/index.ts:126-151 (schema)

  Input schema defining the required icon_name (string) and style (string with enum of supported styles) parameters for the tool.

  inputSchema: {
    type: "object",
    properties: {
      icon_name: {
        type: "string",
        description: "The name of the icon (e.g., 'home-01', 'notification-02')",
      },
      style: {
        type: "string",
        description: "The icon style",
        enum: [
          "bulk-rounded",
          "duotone-rounded",
          "duotone-standard",
          "solid-rounded",
          "solid-sharp",
          "solid-standard",
          "stroke-rounded",
          "stroke-sharp",
          "stroke-standard",
          "twotone-rounded"
        ]
      }
    },
    required: ["icon_name", "style"],
  },

• src/index.ts:123-152 (registration)

  Registration of the get_icon_glyph_by_style tool in the ListToolsRequestSchema response, including name, description, and input schema.

  {
    name: "get_icon_glyph_by_style",
    description: "Get the glyph (unicode character) for a specific icon with a particular style",
    inputSchema: {
      type: "object",
      properties: {
        icon_name: {
          type: "string",
          description: "The name of the icon (e.g., 'home-01', 'notification-02')",
        },
        style: {
          type: "string",
          description: "The icon style",
          enum: [
            "bulk-rounded",
            "duotone-rounded",
            "duotone-standard",
            "solid-rounded",
            "solid-sharp",
            "solid-standard",
            "stroke-rounded",
            "stroke-sharp",
            "stroke-standard",
            "twotone-rounded"
          ]
        }
      },
      required: ["icon_name", "style"],
    },
  },

• src/utils/glyphs.ts:44-79 (helper)

  Helper function implementing the core logic: fetches the specific glyph (primary and secondary unicode) for an icon and style from the Hugeicons API.

  export async function getGlyphByStyle(iconName: string, style: IconStyle): Promise<{ primary: Glyph; secondary: Glyph | null }> {
      if (!iconName || !iconName.trim()) {
          throw new Error('Icon name is required');
      }
  
      if (!style || !style.trim()) {
          throw new Error('Style is required');
      }
  
      try {
          const response = await axios.get<SingleGlyphResponse>(
              `${HUGEICONS_API_BASE}/icon/${iconName.trim()}/glyph`,
              {
                  params: { style: style.trim() },
                  headers: {
                      'accept': 'application/json'
                  },
                  timeout: 10000, // 10 second timeout
              }
          );
  
          if (!response.data.success) {
              throw new Error(response.data.message || 'Failed to fetch glyph');
          }
  
          return response.data.data;
      } catch (error: any) {
          if (error.response?.status === 404) {
              throw new Error(`Icon '${iconName}' with style '${style}' not found`);
          }
          if (error.message) {
              throw new Error(`Failed to fetch glyph: ${error.message}`);
          }
          throw new Error('Failed to fetch glyph');
      }
  }

• src/index.ts:462-492 (helper)

  Validation helper for the style parameter, ensuring it matches the supported IconStyle enum.

  private validateIconStyle(args: any): IconStyle {
    if (!args || typeof args.style !== "string" || !args.style.trim()) {
      throw new McpError(
        ErrorCode.InvalidRequest,
        "Style must be a non-empty string"
      );
    }
  
    const validStyles: IconStyle[] = [
      'bulk-rounded',
      'duotone-rounded',
      'duotone-standard',
      'solid-rounded',
      'solid-sharp',
      'solid-standard',
      'stroke-rounded',
      'stroke-sharp',
      'stroke-standard',
      'twotone-rounded'
    ];
  
    const style = args.style.trim() as IconStyle;
    if (!validStyles.includes(style)) {
      throw new McpError(
        ErrorCode.InvalidRequest,
        `Invalid style. Supported styles are: ${validStyles.join(', ')}`
      );
    }
  
    return style;
  }
