Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@captapi/mcp) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@captapi/mcp

Official Captapi MCP server. Give Claude, Cursor, VS Code, and any MCP-compatible AI agent direct access to 62 social media data endpoints across YouTube, TikTok, Instagram, and Facebook — transcripts, summaries, comments, channel stats, search, bulk lists, and downloads.

One Captapi key works across every platform. The agent calls a tool, Captapi handles proxies, rate limits, retries, and auth, and returns clean JSON.

Quick start

You need a Captapi API key (capt_live_...). Get one at captapi.com/dashboard/api-keys.

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project):

{
  "mcpServers": {
    "captapi": {
      "command": "npx",
      "args": ["-y", "@captapi/mcp"],
      "env": {
        "CAPTAPI_API_KEY": "capt_live_xxxxxxxxxxxxxxxx"
      }
    }
  }
}

Claude Desktop

Add the same block to claude_desktop_config.json (Settings → Developer → Edit Config).

VS Code

Add to .vscode/mcp.json:

{
  "servers": {
    "captapi": {
      "command": "npx",
      "args": ["-y", "@captapi/mcp"],
      "env": {
        "CAPTAPI_API_KEY": "capt_live_xxxxxxxxxxxxxxxx"
      }
    }
  }
}

Tools

Each endpoint is exposed as a tool named <platform>_<action>, e.g. youtube_transcript, tiktok_comments, instagram_channel_posts, facebook_profile_posts. Inputs:

Search tools take q (query) and optional limit.
Channel tools take a profile/channel url.
