Implementation Reference

• tools/misc.ts:28-52 (handler)

  The handler function that implements the core logic of the 'favourite_studio' tool. It performs authentication, calls the external AniList library's favouriteStudio method with the provided studio ID, and returns a formatted text response indicating success or failure.

  async ({ id }) => {
    try {
      const auth = requireAuth(config.anilistToken);
      if (!auth.isAuthorized) {
        return auth.errorResponse;
      }
  
      const result = await anilist.favouriteStudio(id);
      return {
        content: [
          {
            type: "text",
            text: result
              ? `Successfully added studio with ID ${id} to favourites.`
              : `Studio with ID ${id} was removed from favourites or operation failed.`,
          },
        ],
      };
    } catch (error: any) {
      return {
        content: [{ type: "text", text: `Error: ${error.message}` }],
        isError: true,
      };
    }
  },

• tools/misc.ts:16-20 (schema)

  Input schema using Zod to validate the 'id' parameter as a number, with a descriptive annotation.

  {
    id: z
      .number()
      .describe("The AniList ID of the studio to favourite/unfavourite"),
  },

• tools/misc.ts:13-53 (registration)

  The registration of the 'favourite_studio' tool on the MCP server, specifying name, description, input schema, hints, and handler function.

  server.tool(
    "favourite_studio",
    "[Requires Login] Favourite or unfavourite a studio by its ID",
    {
      id: z
        .number()
        .describe("The AniList ID of the studio to favourite/unfavourite"),
    },
    {
      title: "Favourite/Unfavourite Studio",
      readOnlyHint: false,
      destructiveHint: true,
      idempotentHint: false,
      openWorldHint: true,
    },
    async ({ id }) => {
      try {
        const auth = requireAuth(config.anilistToken);
        if (!auth.isAuthorized) {
          return auth.errorResponse;
        }
  
        const result = await anilist.favouriteStudio(id);
        return {
          content: [
            {
              type: "text",
              text: result
                ? `Successfully added studio with ID ${id} to favourites.`
                : `Studio with ID ${id} was removed from favourites or operation failed.`,
            },
          ],
        };
      } catch (error: any) {
        return {
          content: [{ type: "text", text: `Error: ${error.message}` }],
          isError: true,
        };
      }
    },
  );
