Implementation Reference

• tools/media.ts:68-107 (registration)

  Registration of the 'favourite_anime' MCP tool, including description, input schema, metadata hints, and inline handler function that performs auth check and calls the external anilist.media.favouriteAnime(id).

    "favourite_anime",
    "[Requires Login] Favourite or unfavourite an anime by its ID",
    {
      id: z
        .number()
        .describe("The AniList ID of the anime to favourite/unfavourite"),
    },
    {
      title: "Favourite/Unfavourite Anime",
      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.media.favouriteAnime(id);
        return {
          content: [
            {
              type: "text",
              text: result
                ? `Successfully added anime with ID ${id} to favourites.`
                : `Anime with ID ${id} was removed from favourites or operation failed.`,
            },
          ],
        };
      } catch (error: any) {
        return {
          content: [{ type: "text", text: `Error: ${error.message}` }],
          isError: true,
        };
      }
    },
  );

• tools/media.ts:82-106 (handler)

  The core handler logic for the 'favourite_anime' tool: checks authentication using requireAuth, toggles the anime favorite status via anilist.media.favouriteAnime(id), and returns success/error message.

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

• tools/media.ts:70-74 (schema)

  Input schema using Zod: requires 'id' as a number (AniList anime ID).

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