XReply — AI Post Generator

Generate, schedule, and publish posts to X and LinkedIn in your voice using AI. Browse viral content for inspiration, manage your post queue, and track billing and quota.

Authentication

All tools require an XREPLY_TOKEN environment variable — a JWT token from XreplyAI Settings. This is automatically injected by OpenClaw when set in your skill config.

MCP Server

The XReply MCP server is published as @xreplyai/mcp on npm. You invoke tools via mcporter:

mcporter call 'npx @xreplyai/mcp@0.3.11' <tool_name> [param:value ...]

To discover all available tools and their parameters:

mcporter list 'npx @xreplyai/mcp@0.3.11' --all-parameters

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@0.3.11' xreply_posts_generate
mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_posts_generate topic:"my SaaS hit 1000 users"
mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_posts_generate topic:"lessons from year 1" angle:story_arc
mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_posts_generate platform:linkedin topic:"leadership lessons"
mcporter call 'npx @xreplyai/mcp@0.3.11' 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.

mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_posts_generate_batch category:personalized count:5
mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_posts_generate_batch category:trending count:3
mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_posts_generate_batch category:viral count:9

Parameters:

• category (required): personalized | trending | viral
• count (required): number of posts to generate (1–9, must not exceed remaining daily quota)

Media Upload

xreply_media_upload

Upload an image file from disk and get back a media identifier to attach to a post. Call this before xreply_posts_create or xreply_posts_edit to attach images. Supports JPEG, PNG, GIF, and WebP up to 5 MB.

Note: Requires filesystem access — works in Claude Code, Cursor, and mcporter CLI. Not available in Claude.ai (no filesystem); in that case use the Posts dashboard at app.xreplyai.com/dashboard/posts to attach images directly.

Upload an image for X:

mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_media_upload image_path:/path/to/photo.jpg platform:twitter
→ returns { platform: "twitter", media_id: "1234567890" }

Upload an image for LinkedIn:

mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_media_upload image_path:/path/to/photo.png platform:linkedin
→ returns { platform: "linkedin", asset_urn: "urn:li:digitalmediaAsset:..." }

Parameters:

• image_path (required): absolute or relative path to the image file on disk
• platform (required): twitter | linkedin
• content_type (optional): image/jpeg | image/png | image/gif | image/webp — inferred from extension if omitted

Use the returned identifier in post_contents[].metadata:

• X single image: metadata: { media_id: "..." }
• X multiple images: metadata: { media_ids: ["...", "..."] }
• LinkedIn single image: metadata: { asset_urn: "urn:li:..." }
• LinkedIn multiple images: metadata: { asset_urns: ["urn:li:...", "urn:li:..."] }

xreply_video_upload

Upload an MP4 video file from disk to LinkedIn and get back an asset URN to attach to a post. Uses your primary connected LinkedIn account. Call this before xreply_posts_create or xreply_posts_edit to attach a video. Supports MP4 only, up to 100 MB.

Note: Only LinkedIn is supported — X video upload requires OAuth 1.0a which is not currently supported. Requires filesystem access — works in Claude Code, Cursor, and mcporter CLI. Not available in Claude.ai; use the Posts dashboard at app.xreplyai.com/dashboard/posts to attach videos directly.

Upload a video for LinkedIn:

mcporter call 'npx @xreplyai/mcp@0.3.11' xreply_video_upload video_path:/path/to/video.mp4
→ returns { platform: "linkedin", asset_urn: "urn:li:video:ABC123" }

Parameters:

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@0.3.11' xreply_posts_publish id:123 account_id:1
mcporter call 'npx @xreplyai/mcp@0.3.11' 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_list_social_accounts to discover available account IDs (works even for newly connected accounts with no posts yet), then retry with the correct ID.

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.

Media upload — file not found: If xreply_media_upload cannot read the file, check that the path is correct and accessible. Use an absolute path to avoid ambiguity.

Media upload — file too large: Maximum image size is 5 MB. Compress or resize the image before retrying.

Media upload — unsupported format: Only JPEG, PNG, GIF, and WebP are supported. Convert the image to a supported format.

Media upload — no X account connected: If the Twitter upload returns NO_TWITTER_ACCOUNT, the user must connect their X account in XreplyAI Settings first.

Claude.ai users: xreply_media_upload and xreply_video_upload require filesystem access and are not available in Claude.ai (which has no disk access). Use the Posts dashboard at app.xreplyai.com/dashboard/posts to attach images or videos via the compose or edit form.

Video upload — unsupported format: Only MP4 is supported for video. Convert the video to MP4 before retrying.

Video upload — file too large: Maximum video size is 100 MB. Compress the video before retrying.

Video upload — no LinkedIn account connected: If xreply_video_upload returns NO_LINKEDIN_ACCOUNT, the user must connect their LinkedIn account in XreplyAI Settings first.

Video upload — X not supported: X video upload requires OAuth 1.0a which is not currently supported. For X videos, use the Posts dashboard at app.xreplyai.com/dashboard/posts.
