Delete Post or Comment

Instructions

Implementation Reference

• src/tools/post.ts:259-261 (registration)

  Registration of the 'delete_content' tool with the MCP server. Registers the tool name, title, description, and input schema for deleting a Reddit post or comment.

  server.registerTool(
    "delete_content",
    {

• src/tools/post.ts:264-268 (schema)

  Input schema for 'delete_content': requires a 'url' string parameter (full Reddit URL of the post or comment to delete).

  inputSchema: z.object({
    url: z
      .string()
      .describe("Full Reddit URL of your post or comment to delete"),
  }),

• src/tools/post.ts:270-311 (handler)

  Handler function that executes the delete logic. Extracts the thing ID from the URL using extractThingId, then calls client.post('/api/del', { id: thingId }) to delete the post or comment. Returns success/failure response.

    async ({ url }) => {
      try {
        const thingId = extractThingId(url);
        if (!thingId) {
          return {
            content: [
              {
                type: "text" as const,
                text: "Could not extract post/comment ID from URL.",
              },
            ],
            isError: true,
          };
        }
  
        await client.post("/api/del", { id: thingId });
  
        return {
          content: [
            {
              type: "text" as const,
              text: JSON.stringify(
                { success: true, id: thingId, deleted: true },
                null,
                2
              ),
            },
          ],
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text" as const,
              text: `Error deleting: ${error instanceof Error ? error.message : String(error)}`,
            },
          ],
          isError: true,
        };
      }
    }
  );

• src/tools/post.ts:5-15 (helper)

  Helper function extractThingId that parses a Reddit URL to extract the post/comment ID (t3_ for posts, t1_ for comments).

  function extractThingId(url: string): string | null {
    // Extract thing ID from URL like /r/sub/comments/abc123/title/
    const match = url.match(/\/comments\/([a-z0-9]+)/i);
    if (match) return `t3_${match[1]}`;
    // Or from a comment URL /r/sub/comments/postid/title/commentid/
    const commentMatch = url.match(
      /\/comments\/[a-z0-9]+\/[^/]*\/([a-z0-9]+)/i
    );
    if (commentMatch) return `t1_${commentMatch[1]}`;
    return null;
  }

• src/reddit/client.ts:159-185 (helper)

  RedditClient.post method used by the delete handler to make the POST request to /api/del endpoint.

  async post(
    endpoint: string,
    body: Record<string, string>
  ): Promise<any> {
    await this.ensureToken();
    if (!this.session?.username) {
      throw new Error(
        "Write operations require authentication. Run the 'authorize' tool first to connect your Reddit account (one-time browser authorization)."
      );
    }
    const url = endpoint.startsWith("http")
      ? endpoint
      : `${OAUTH_BASE}${endpoint}`;
    const res = await fetch(url, {
      method: "POST",
      headers: {
        "Content-Type": "application/x-www-form-urlencoded",
        Authorization: `Bearer ${this.session!.accessToken}`,
        "User-Agent": this.userAgent,
      },
      body: new URLSearchParams({
        ...body,
        api_type: "json",
      }),
    });
    return res.json();
  }
