XreplyAI — AI Post Generator

Generate, schedule, and publish posts to X, LinkedIn, and Threads in your voice using AI. Manage your post queue, preferences, 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 XreplyAI MCP server is published as @xreplyai/mcp on npm. You invoke tools via mcporter:

mcporter call 'npx @xreplyai/mcp@0.3.19' <tool_name> [param:value ...]

To discover all available tools and their parameters:

mcporter list 'npx @xreplyai/mcp@0.3.19' --all-parameters

Tools

Generation

xreply_posts_generate

Generate AI post(s) in the user's voice and auto-save as draft(s). Use platform for a single platform or platforms (array) to generate platform-native variants for multiple platforms at once. Each platform variant counts as 1 against the daily quota (5/day free, 100/day pro).

mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_generate
mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_generate topic:"my SaaS hit 1000 users"
mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_generate topic:"lessons from year 1" angle:story_arc
mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_generate platform:linkedin topic:"leadership lessons"
mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_generate angle:one_liner
mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_generate topic:"entrepreneurship hardships" 'platforms:["twitter","linkedin","threads"]'

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): twitter (default) | linkedin | threads | instagram | youtube — single platform, controls output length and style
• platforms (optional): array of 2–5 platforms — generates platform-native variants for each. Returns variants array + single combined post draft. Each variant counts as 1 quota.

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@0.3.19' xreply_posts_generate_batch category:personalized count:5
mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_generate_batch category:trending count:3

Parameters:

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

Post Management

mcporter call 'npx @xreplyai/mcp@0.3.19' 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, Threads, or when posting different content to multiple platforms. The post is not published until you call xreply_posts_publish.

X-only post (simple):

mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_create body:"Your tweet text here"

X post with auto-retweet:

mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_create post_contents:'[{"platform":"twitter","body":"Tweet text","metadata":{"auto_rt_hours":24}}]'

LinkedIn post:

mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_create post_contents:'[{"platform":"linkedin","body":"Your long LinkedIn post here..."}]'

Cross-post to X and LinkedIn with different text:

For auto-retweet: { auto_rt_hours: 24 }. For X communities: { community_id: "12345" } (use xreply_list_twitter_communities to get IDs).
• account_id / account_ids (optional): social account(s) to post from

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@0.3.19' xreply_posts_edit id:123 body:"Updated tweet text"
mcporter call 'npx @xreplyai/mcp@0.3.19' xreply_posts_edit id:123 'scheduled_at:2026-03-15T09:00:00Z'

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@0.3.19' 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@0.3.19' 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@0.3.19' xreply_video_upload video_path:/path/to/video.mp4
→ returns { platform: "linkedin", asset_urn: "urn:li:video:ABC123" }

Parameters:

• video_path (required): absolute or relative path to the MP4 file on disk (max 100 MB)

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.

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.

Rules list requires Pro: If xreply_rules_list returns a 403, inform the user this feature requires 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.

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

Threads token expired: If a Threads post returns THREADS_TOKEN_EXPIRED, the access token has expired (Threads tokens expire after ~60 days). Direct the user to XreplyAI Settings to reconnect their Threads account.

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.
