Implementation Reference

• operations/issues.ts:59-69 (handler)

  The core handler function that executes the GitHub API POST request to add a comment to the specified issue.

  export async function addIssueComment(
    owner: string,
    repo: string,
    issue_number: number,
    body: string
  ) {
    return githubRequest(`https://api.github.com/repos/${owner}/${repo}/issues/${issue_number}/comments`, {
      method: "POST",
      body: { body },
    });
  }

• operations/issues.ts:10-15 (schema)

  Zod schema defining the input parameters (owner, repo, issue_number, body) for the add_issue_comment tool.

  export const IssueCommentSchema = z.object({
    owner: z.string(),
    repo: z.string(),
    issue_number: z.number(),
    body: z.string(),
  });

• index.ts:133-137 (registration)

  Registration of the add_issue_comment tool in the MCP server's list of tools, specifying name, description, and input schema.

  {
    name: "add_issue_comment",
    description: "Add a comment to an existing issue",
    inputSchema: zodToJsonSchema(issues.IssueCommentSchema)
  },

• index.ts:326-333 (registration)

  Dispatch/execution handler in the CallToolRequest switch statement that parses arguments and calls the addIssueComment function.

  case "add_issue_comment": {
    const args = issues.IssueCommentSchema.parse(request.params.arguments);
    const { owner, repo, issue_number, body } = args;
    const result = await issues.addIssueComment(owner, repo, issue_number, body);
    return {
      content: [{ type: "text", text: JSON.stringify(result, null, 2) }],
    };
  }
