Instructions

Implementation Reference

• src/tools/issues.ts:45-73 (handler)

  The handler function for the 'add_issue_comment' MCP tool. Calls `octokit.rest.issues.createComment` to add a comment to a GitHub issue. Takes owner, repo, issue_number, and body as input, and returns the comment URL and ID on success.

  // Tool: Add Issue Comment
  server.tool(
  	"add_issue_comment",
  	"Add a comment to a specific issue in a GitHub repository.",
  	{
  		owner: z.string().describe("Repository owner"),
  		repo: z.string().describe("Repository name"),
  		issue_number: z.number().describe("Issue number to comment on"),
  		body: z.string().describe("Comment content"),
  	},
  	async ({ owner, repo, issue_number, body }) => {
  		try {
  			const response = await octokit.rest.issues.createComment({
  				owner,
  				repo,
  				issue_number,
  				body,
  			})
  			const c = response.data
  			return {
  				content: [{ type: "text", text: `Comment added to #${issue_number}\nURL: ${c.html_url}\nID: ${c.id}` }],
  			}
  		} catch (e: any) {
  			return {
  				content: [{ type: "text", text: `Error: ${e.message}` }],
  			}
  		}
  	},
  )

• src/tools/issues.ts:49-54 (schema)

  Input schema for 'add_issue_comment' defining required parameters: owner (string), repo (string), issue_number (number), and body (string), each with Zod validation and descriptions.

  {
  	owner: z.string().describe("Repository owner"),
  	repo: z.string().describe("Repository name"),
  	issue_number: z.number().describe("Issue number to comment on"),
  	body: z.string().describe("Comment content"),
  },

• src/tools/issues.ts:46-73 (registration)

  Registration of the tool via `server.tool("add_issue_comment", ...)` within the `registerIssueTools` function.

  server.tool(
  	"add_issue_comment",
  	"Add a comment to a specific issue in a GitHub repository.",
  	{
  		owner: z.string().describe("Repository owner"),
  		repo: z.string().describe("Repository name"),
  		issue_number: z.number().describe("Issue number to comment on"),
  		body: z.string().describe("Comment content"),
  	},
  	async ({ owner, repo, issue_number, body }) => {
  		try {
  			const response = await octokit.rest.issues.createComment({
  				owner,
  				repo,
  				issue_number,
  				body,
  			})
  			const c = response.data
  			return {
  				content: [{ type: "text", text: `Comment added to #${issue_number}\nURL: ${c.html_url}\nID: ${c.id}` }],
  			}
  		} catch (e: any) {
  			return {
  				content: [{ type: "text", text: `Error: ${e.message}` }],
  			}
  		}
  	},
  )

• src/index.ts:14-16 (registration)

  The `registerAllToolsAndResources` function calls `registerIssueTools(server, octokit)` which registers all issue tools including 'add_issue_comment'.

  export function registerAllToolsAndResources(server: McpServer, octokit: Octokit): void {
  	registerSearchTools(server, octokit)
  	registerIssueTools(server, octokit)
