Implementation Reference

• src/mcp/tools/user-tools.ts:24-38 (handler)

  The inline async handler function for the get_user_profile tool. It takes a username, fetches the profile data from the LeetCode service, and returns it as a text content block containing JSON with the username and profile data.

  async ({ username }) => {
      const data =
          await this.leetcodeService.fetchUserProfile(username);
      return {
          content: [
              {
                  type: "text",
                  text: JSON.stringify({
                      username: username,
                      profile: data
                  })
              }
          ]
      };
  }

• src/mcp/tools/user-tools.ts:17-23 (schema)

  Zod input schema defining the required 'username' parameter as a string with description.

  {
      username: z
          .string()
          .describe(
              "LeetCode username to retrieve profile information for"
          )
  },

• src/mcp/tools/user-tools.ts:14-39 (registration)

  Registration of the 'get_user_profile' tool using server.tool(), including the tool name, description, input schema, and inline handler function within the UserToolRegistry's registerCommon method.

  this.server.tool(
      "get_user_profile",
      "Retrieves profile information about a LeetCode user, including user stats, solved problems, and profile details",
      {
          username: z
              .string()
              .describe(
                  "LeetCode username to retrieve profile information for"
              )
      },
      async ({ username }) => {
          const data =
              await this.leetcodeService.fetchUserProfile(username);
          return {
              content: [
                  {
                      type: "text",
                      text: JSON.stringify({
                          username: username,
                          profile: data
                      })
                  }
