@viralnote/mcp-server

A Model Context Protocol server for the ViralNote social media API.

Plug it into Claude Desktop, Claude Code, Cursor, or any other MCP-aware host and your agent can schedule posts, manage media, and read analytics across X, Instagram, Facebook, TikTok, LinkedIn, YouTube, Pinterest, Bluesky, Threads, and Reddit — as native MCP tool calls. No glue code.

Install

Claude Desktop / Claude Code / Cursor

Add to your MCP config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, similar on other platforms):

{
  "mcpServers": {
    "viralnote": {
      "command": "npx",
      "args": ["-y", "@viralnote/mcp-server"],
      "env": {
        "VIRALNOTE_API_KEY": "vnd_..."
      }
    }
  }
}

Restart your MCP host. The ViralNote tools will be available immediately.

Local install

npm install -g @viralnote/mcp-server

Then reference viralnote-mcp directly in your MCP config:

{
  "mcpServers": {
    "viralnote": {
      "command": "viralnote-mcp",
      "env": { "VIRALNOTE_API_KEY": "vnd_..." }
    }
  }
}

Configuration

| Env var | Required | Default | Notes | |---|---|---|---| | VIRALNOTE_API_KEY | yes | — | Generate at viralnote.app/developers/auth. Grant posts:read, posts:write, plus webhooks:* if your agent should manage webhooks. | | VIRALNOTE_API_BASE | no | https://viralnote.app/api/v1 | Override for staging/self-hosted instances. |

Tools exposed

| Tool | Purpose | |---|---| | list_posts | List posts (filter by status/platform, paginated) | | get_post | Read one post including per-platform publish results | | create_post | Create a draft (is_draft: true) or scheduled post | | update_post | Update a draft or scheduled post | | delete_post | Delete (cancels if scheduled) | | publish_post | Publish a draft now | | list_media | List media library items | | import_media | Import by URL (200MB) or base64 data (3MB) | | delete_media | Delete a media item | | list_social_accounts | List connected social accounts | | list_analytics | Published posts with per-platform metrics | | list_post_results | Per-platform delivery results (success/error) | | list_webhooks | List webhook subscriptions | | create_webhook | Subscribe to events | | delete_webhook | Unsubscribe |

For most users, the HTTP MCP server at https://viralnote.app/api/mcp/mcp is simpler than installing this stdio package — see https://viralnote.app/developers/mcp for the HTTP config snippet. Use this stdio package when your MCP client doesn't support HTTP transport.

The underlying REST endpoints and request/response shapes are documented at viralnote.app/developers/docs.

Example agent prompts

"Show me my last 5 scheduled posts." Tool: list_posts with { status: "scheduled", limit: 5 }.

"Schedule this caption to Instagram for tomorrow at 9am, attaching the photo I uploaded yesterday." Tools: list_media → find item → create_post with { platforms: ["instagram"], caption, libraryItemId, scheduledFor, status: "scheduled" }.

"Pull this Dropbox link into my library, then publish it to X immediately." Tools: import_media → create_post (draft) → publish_post.
