The Model Context Protocol (MCP) lets an AI assistant call Postprism directly: draft and schedule posts, attach media, read analytics and switch between workspaces. The tools call the same REST API documented here, so limits and validation are identical.

Connect

Clients that support remote MCP servers can add the URL directly. For Claude Desktop, Cursor, Gemini CLI and other clients that use a JSON config, add Postprism through mcp-remote, the same snippet shown on the Developer page in Postprism. A browser tab opens so you can sign in and approve access.

MCP config

{
  "mcpServers": {
    "postprism": {
      "command": "npx",
      "args": [
        "[email protected]",
        "https://studio.postprism.app/api/mcp"
      ]
    }
  }
}

Step-by-step guides: Claude, Claude Code, ChatGPT, Cursor, Gemini and n8n (REST API).

Every connected assistant is listed on the Developer page in Postprism, where Revoke access disconnects it.

Tools

Tool	What it does	REST equivalent
`list_posts`	List posts in a workspace, filtered by status (draft, scheduled, published).	`GET /api/v1/posts`
`create_post`	Create a post from base content, target platforms and optional per-platform versions. Without a date it is saved as a draft; with scheduled_at it is scheduled.	`POST /api/v1/posts`
`get_post`	Read a single post by ID.	`GET /api/v1/posts/{id}`
`update_post`	Change a post: copy, per-platform versions, media or the scheduled time.	`PATCH /api/v1/posts/{id}`
`delete_post`	Delete a post by ID.	`DELETE /api/v1/posts/{id}`
`upload_media`	Upload an image or video (JPEG, PNG, GIF, WebP, MP4, MOV, up to 10 MB) and get a URL to attach to a post.	`POST /api/v1/media` (base64)
`get_analytics`	List analytics records, filtered by post or platform.	`GET /api/v1/analytics`
`get_post_analytics`	Every analytics record for one post.	`GET /api/v1/analytics?post_id=`
`list_platforms`	The social accounts connected to a workspace.	`GET /api/v1/platforms`
`list_workspaces`	Every workspace you belong to, so one agent can act for several brands.	`GET /api/v1/workspaces`
`get_workspace_info`	The current workspace name and plan.	`GET /api/v1/workspace`

Tips for agents

Call list_platforms before create_post and use the returned platform keys.
Write a version per platform in platform_content; that is the text that publishes.
Leave out scheduled_at to create drafts a person reviews in Postprism. Add it only when the user asked to schedule.
Upload files with upload_media (base64, up to 10 MB) and pass the returned url in media.
Pass workspace_id from list_workspaces to work on another brand or client.
