| description | Schedule, publish and analyze social posts across 15 networks via BulkPublish (MCP or REST) — Facebook, Instagram, X, TikTok, YouTube, Threads, Bluesky, Pinterest, Google Business, LinkedIn, Mastodon, Discord, Telegram, Tumblr, Snapchat. Use when the user wants to post, schedule, or bulk-publish to social media, check connected channels, or read post analytics. Always check platform rules before composing. |

Social Publishing via BulkPublish
Cross-platform scheduling and publishing through one API. Unlike per-platform skills, this
targets many networks in a single call, with each platform's rules enforced up front.
Setup
MCP (recommended) — hosted server, no install:
claude mcp add --transport http bulkpublish https://mcp.bulkpublish.com/mcp
Add it as a custom connector and OAuth 2.1 walks you through consent — no key in the URL.
Or the npm server (stdio):
claude mcp add bulkpublish --env BULKPUBLISH_API_KEY=bp_your_key -- npx -y @bulkpublish/mcp-server
Or plain REST: https://app.bulkpublish.com/api, spec at
https://app.bulkpublish.com/openapi.json, docs at https://app.bulkpublish.com/docs.
Get an API key at app.bulkpublish.com/developer and
send it as Authorization: Bearer <key>. API and MCP access are on every plan, free included.
Workflow
list_channels — get connected accounts with their channelId and platform. Do this
first; never guess a channel id.
- Check the platform rules below (or
get_channel_options) before composing.
- Upload media if needed —
upload_media takes a public url or a local filePath, and
returns the id you pass in mediaFileIds.
create_post with content, channels, and status: "scheduled" plus scheduledAt
(or leave it a draft, then publish_post when the user confirms).
- Confirm the exact text, target accounts, and time with the user before publishing.
create_post essentials
content (string, required) — post text
channels (array, required) — [{ channelId: number, platform: string }]
status ("draft" | "scheduled") — default "draft"
scheduledAt (ISO 8601 string) — required when status is "scheduled"
timezone (string) — e.g. "America/New_York"
mediaFileIds (number[]) — ids from upload_media
platformContent (object) — per-platform text override
postTypeOverrides (object) — per-platform post type, e.g. {"instagram":"reel"}
platformSpecific (object) — per-platform extras (titles, link previews)
requestApproval (boolean, false) — hold the post for human review
create_post schedules or drafts. To send something out immediately, create it and then call
publish_post; retry_post re-runs a failed one.
Platform rules that actually break posts
- YouTube and TikTok require video. Never include them on an image-only or text-only post.
- YouTube and Pinterest require a title — set
platformSpecific.youtube.title /
platformSpecific.pinterest.title.
- Instagram defaults to
feed_photo. With a video you must set
postTypeOverrides.instagram to reel or feed_video, or the post fails.
- Instagram needs a Business or Creator account — personal accounts are rejected.
- Character limits differ sharply: X 280, Bluesky 300, Threads / Mastodon / Google Business
500, Pinterest 1,500, Discord 2,000, Instagram / TikTok 2,200, LinkedIn 3,000, Telegram 4,096,
YouTube 5,000, Facebook 63,206. Use
platformContent to give the short networks their own
trimmed text rather than truncating everything down to the smallest limit.
- Facebook cannot mix images and video in one post.
Approvals
Posts carry an approvalStatus (none | pending | approved | rejected) separate from
status. The scheduler never publishes a pending or rejected post. Pass
requestApproval: true to hold a post for a human; approve_post / reject_post release it.
API keys whose role lacks post:publish always have it forced on and get 403 APPROVAL_REQUIRED from publish and retry — that is expected, not a bug.
Analytics
get_analytics takes startDate / endDate (ISO dates) and returns a summary with a
per-platform breakdown; get_post_metrics covers a single post. Outbound linkClicks are
measured by BulkPublish's own short links and are reported separately from clicks — one
visit can appear in both, so never add them together.
Other tools
get_channel_health (re-auth needed?), get_queue_slot (next optimal time for a timezone),
create_schedule (recurring posts), list_labels, get_quota_usage (plan limits and usage).
Rules
- Read the docs or the OpenAPI spec rather than inventing endpoints or parameters.
- Confirm channel ids from
list_channels before every publish.
- Show the user the exact text, accounts and time before anything goes out.
- If a platform cannot do what was asked, say so instead of silently dropping it.
