HowToCook-MCP Server

Instructions

Implementation Reference

• src/tools/getAllRecipes.ts:14-25 (handler)

  Executes the tool logic: simplifies all recipes to name and description only, stringifies to JSON, and returns in MCP content format.

  async () => {
    // 返回更简化版的菜谱数据，只包含name和description
    const simplifiedRecipes = recipes.map(simplifyRecipeNameOnly);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(simplifiedRecipes, null, 2),
        },
      ],
    };
  }

• src/tools/getAllRecipes.ts:10-13 (schema)

  Input schema using Zod: optional string parameter 'no_param'.

  {
    'no_param': z.string().optional()
                     .describe('无参数')
  },

• src/tools/getAllRecipes.ts:7-26 (registration)

  Registers the tool on the MCP server with name, description, input schema, and handler function.

  server.tool(
    "mcp_howtocook_getAllRecipes",
    "获取所有菜谱",
    {
      'no_param': z.string().optional()
                       .describe('无参数')
    },
    async () => {
      // 返回更简化版的菜谱数据，只包含name和description
      const simplifiedRecipes = recipes.map(simplifyRecipeNameOnly);
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(simplifiedRecipes, null, 2),
          },
        ],
      };
    }
  );

• src/index.ts:56-56 (registration)

  Invokes the registration function during server instance creation, passing the server and loaded recipes.

  registerGetAllRecipesTool(server, recipes);

• src/utils/recipeUtils.ts:17-22 (helper)

  Utility function that simplifies a Recipe to just name and description, used in the tool handler.

  export function simplifyRecipeNameOnly(recipe: Recipe): NameOnlyRecipe {
    return {
      name: recipe.name,
      description: recipe.description
    };
  }
