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

1. list_channels, get connected accounts with their channelId and platform. Do this first; never guess a channel id.
2. Check the platform rules below (or get_channel_options) before composing.
3. Upload media if needed, upload_media takes a public url or a local filePath, and returns the id you pass in mediaFileIds.
4. create_post with content, channels, and status: "scheduled" plus scheduledAt (or leave it a draft, then publish_post when the user confirms).
5. Confirm the exact text, target accounts, and time with the user before publishing.
