src/tools/userCollection.ts:260-274 (handler)

Full tool object definition, including the 'execute' handler function that implements the core logic for retrieving the minimum, median, and maximum values of a Discogs user's collection using the UserService.

export const getUserCollectionValueTool: Tool<FastMCPSessionAuth, typeof UsernameInputSchema> = {
  name: 'get_user_collection_value',
  description: `Returns the minimum, median, and maximum value of a user's collection`,
  parameters: UsernameInputSchema,
  execute: async (args) => {
    try {
      const userService = new UserService();
      const collectionValue = await userService.collection.getValue(args);

      return JSON.stringify(collectionValue);
    } catch (error) {
      throw formatDiscogsError(error);
    }
  },
};

src/types/common.ts:123-125 (schema)
Zod input schema used by the tool, requiring a non-empty 'username' string.

});
```
