Generation

xreply_posts_generate

Generate a single AI post in the user's voice and auto-save it as a draft. Specify platform to control output length and style — X posts are capped at 280 chars, LinkedIn posts up to 3000 chars. Returns the generated body and saved post ID. Counts as 1 against the daily quota (5/day free, 100/day pro).

mcporter call 'npx @xreplyai/mcp' xreply_posts_generate
mcporter call 'npx @xreplyai/mcp' xreply_posts_generate topic:"my SaaS hit 1000 users"
mcporter call 'npx @xreplyai/mcp' xreply_posts_generate topic:"lessons from year 1" angle:story_arc
mcporter call 'npx @xreplyai/mcp' xreply_posts_generate platform:linkedin topic:"leadership lessons"
mcporter call 'npx @xreplyai/mcp' xreply_posts_generate angle:one_liner

Parameters:

• topic (optional): topic or prompt for the post (max 280 chars)
• angle (optional): one_liner | list | question | story_arc | paragraph | my_voice
• platform (optional): x (default) | linkedin — controls output length and style

xreply_posts_generate_batch

Generate multiple AI posts at once. Each post counts as 1 against the daily quota — check billing first if quota is a concern. A batch of 9 will exhaust a free account.

Post Management

xreply_posts_list

List all posts in the queue — drafts, scheduled, and recent posts. Returns post IDs, body text, status, scheduled times, and per-platform content.

mcporter call 'npx @xreplyai/mcp' xreply_posts_list

No parameters.

xreply_posts_create

Save a post draft. Use body for a simple X-only post. Use post_contents for LinkedIn posts or when posting different content to multiple platforms. The post is not published until you call xreply_posts_publish.

LinkedIn post:

Cross-post to X and LinkedIn with different text:

LinkedIn post with image:

mcporter call 'npx @xreplyai/mcp' xreply_posts_create post_contents:'[{"platform":"linkedin","body":"Caption here","content_type":"single_image","metadata":{"asset_urn":"urn:li:digitalmediaAsset:..."}}]'

Parameters:

• body (optional): X post body text (max 280 chars). Use post_contents for LinkedIn or cross-posting.

xreply_posts_edit

Edit a post's content, scheduled time, or auto-retweet setting. Use body to update X-only text, or post_contents to update per-platform content. Cannot edit posts that are processing or already published.

mcporter call 'npx @xreplyai/mcp' xreply_posts_edit id:123 body:"Updated tweet text"
mcporter call 'npx @xreplyai/mcp' xreply_posts_edit id:123 'scheduled_at:2026-03-15T09:00:00Z'

Parameters:

• id (required): post ID (integer)
• body (optional): new X body text (max 280 chars)
• post_contents (optional): per-platform content to update — replaces content for submitted platforms only. metadata.auto_rt_hours sets X auto-retweet hours; pass null to disable.
• scheduled_at (optional): ISO 8601 datetime string — omit to leave unchanged; pass null to unschedule

xreply_posts_delete

Delete a post. Cannot delete posts that are processing or already published.

mcporter call 'npx @xreplyai/mcp' xreply_posts_delete id:123

Parameters:

• id (required): post ID (integer)

Publishing

xreply_posts_publish

Publish or schedule a post. Requires account_id or account_ids — if neither is provided and no accounts were attached when the post was created, returns NO_ACCOUNT_SPECIFIED. If scheduled_at is provided (ISO 8601), the post will be queued for that time (scheduling horizon depends on your plan). If omitted, the post is published immediately. Each platform (X, LinkedIn) requires the corresponding social account to be connected.

mcporter call 'npx @xreplyai/mcp' xreply_posts_publish id:123 account_id:1
mcporter call 'npx @xreplyai/mcp' xreply_posts_publish id:123 account_id:1 'scheduled_at:2026-03-15T09:00:00Z'

Error Handling

Token expired: If tools return a 401 error, the XREPLY_TOKEN has expired (tokens last 30 days). Ask the user to get a fresh token from XreplyAI Settings and update it in their OpenClaw config.

Quota exhausted: If generation returns a quota error (e.g. "Daily generation quota exhausted"), call xreply_billing_status to check limits and inform the user. Quota resets at midnight.

Quota insufficient for batch: If xreply_posts_generate_batch returns quota_insufficient: true, reduce count to the available value shown in the response, or ask the user to confirm.

Schedule out of range: If scheduling returns a validation error, the requested time exceeds the plan's scheduling horizon. Call xreply_billing_status to check max_schedule_days and suggest an earlier time.

Cannot edit/delete: Posts with status processing or posted cannot be edited or deleted. Call xreply_posts_list to check the current status.

Viral library requires Pro: If xreply_viral_library or xreply_rules_list returns a 403, inform the user these features require a Pro or BYOK subscription.

No account specified: If publish returns NO_ACCOUNT_SPECIFIED, you must pass account_id or account_ids. Call xreply_posts_list to see which accounts are already attached to the post, or ask the user which account to publish from.

LinkedIn account not connected: If publishing to LinkedIn returns a 422, the user has not connected their LinkedIn account. Direct them to XreplyAI Settings to connect it.
