@posteahora/mcp

MCP server for PosteAhora — let AI agents add ideas, create, schedule, and publish social posts across Instagram, X/Twitter, LinkedIn, Threads, Facebook (and more) straight from a chat.

It's a thin wrapper over the PosteAhora public REST API: every call is authenticated with your API key and goes through the same quota, ownership, and publishing pipeline as the web app.

Get an API key

1. Open PosteAhora → Settings → API & integrations.

2. Create a key and copy it (it's shown once). It looks like pah_live_….

Workspaces

A key (and a hosted connector) is bound to one workspace — the one that was active when you created it. So list_accounts, list_posts, list_ideas and get_analytics return that workspace's data, not everything you own. To work in another workspace, create a separate key/connector there. Writes are role-gated: a viewer key can read but not create_post, schedule_post, update_post, delete_post or publish_post_now (those return 403).

Install (Claude Code / Cursor / Windsurf)

Add to your MCP client config:

{
  "mcpServers": {
    "posteahora": {
      "command": "npx",
      "args": ["-y", "@posteahora/mcp"],
      "env": {
        "POSTEAHORA_API_KEY": "pah_live_xxxxxxxx",
        "POSTEAHORA_API_URL": "https://api.posteahora.com/functions/v1/api"
      }
    }
  }
}

• Claude Code: claude mcp add posteahora -e POSTEAHORA_API_KEY=pah_live_… -e POSTEAHORA_API_URL=https://api.posteahora.com/functions/v1/api -- npx -y @posteahora/mcp

• Cursor / Windsurf: add the JSON above to the MCP settings file.

Tools

Typical flow

1. list_accounts → grab the id for each platform you want to post to.

2. (optional) get a publicUrl for your media:

   • Local mode: upload_media with an absolute filePath → publicUrl.

   • Remote/hosted mode: create_upload_url with filename/sizeBytes → uploadUrl + publicUrl; then HTTP PUT the raw bytes to uploadUrl with the matching Content-Type header (e.g. curl -T ./slide.jpg "<uploadUrl>" -H 'Content-Type: image/jpeg'). This works for any size, including video, and is required for TikTok photos (they must be served from our verified cdn.posteahora.com domain).

3. create_post with accountMappings: [{ platform, accountId }], mediaUrls, and status: "published" (or schedule_post with scheduledAt).

Remote / hosted mode (experimental)

npm run start:http starts a stateless Streamable HTTP server on /mcp (PORT, default 8787). The caller's Authorization: Bearer pah_… header is used as the API key (falls back to POSTEAHORA_API_KEY). Put OAuth in front for a production multi-tenant connector.

Development

npm install
npm run build
POSTEAHORA_API_KEY=pah_live_… POSTEAHORA_API_URL=https://api.posteahora.com/functions/v1/api npm start
