FastSaver API for AI agents

Turn Instagram, TikTok, YouTube, Pinterest, Facebook, X, Rutube and Likee links into JSON with direct media download URLs, from your AI agent or coding assistant.

This repository has three things:

An agent skill (skills/fastsaver-api/SKILL.md). It teaches a coding agent how to integrate FastSaver API into an app, bot or script: endpoints, prices, response shapes, errors, retries and code.
A remote MCP server at https://mcp.fastsaver.io/mcp. Your assistant calls FastSaver directly, with seven tools.
A Claude Code plugin that installs both in one step.

Get an API key

Claude Code: skill and MCP server together

/plugin marketplace add coder2077/fastsaver_mcp
/plugin install fastsaver-api@fastsaver

Claude Code asks for your API key when the plugin is enabled and keeps it in secure storage. To set or change it later:

/plugin configure fastsaver-api@fastsaver

The skill alone

Copy the skills/fastsaver-api folder into your agent's skills folder. In Claude Code that is ~/.claude/skills/. The skill follows the open Agent Skills format (https://agentskills.io), so other agents that read SKILL.md skills can use it too.

The MCP server alone

URL: https://mcp.fastsaver.io/mcp (Streamable HTTP, stateless, protocol 2026-07-28 and 2025-11-25).
Auth: your key in the X-Api-Key header, or Authorization: Bearer <key>. Never put the key in the URL.
Listing the tools and list_supported_platforms work without a key.
server.json is its entry for the official MCP Registry (io.fastsaver/api).

Claude Code:

claude mcp add --transport http fastsaver https://mcp.fastsaver.io/mcp --header "X-Api-Key: YOUR_KEY"

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "fastsaver": {
      "url": "https://mcp.fastsaver.io/mcp",
      "headers": { "X-Api-Key": "${env:FASTSAVER_API_KEY}" }
    }
  }
}

VS Code (.vscode/mcp.json):

{
  "inputs": [
    { "type": "promptString", "id": "fastsaver-key", "description": "FastSaver API key", "password": true }
  ],
  "servers": {
    "fastsaver": {
      "type": "http",
      "url": "https://mcp.fastsaver.io/mcp",
      "headers": { "X-Api-Key": "${input:fastsaver-key}" }
    }
  }
}

Codex CLI (~/.codex/config.toml):

[mcp_servers.fastsaver]
url = "https://mcp.fastsaver.io/mcp"
bearer_token_env_var = "FASTSAVER_API_KEY"

Gemini CLI:

gemini mcp add --transport http --header "X-Api-Key: YOUR_KEY" fastsaver https://mcp.fastsaver.io/mcp

Any other client that can send a header: the URL above plus the X-Api-Key header.

Tools

Tool	What it does	Credits
`fetch_media`	Direct links and metadata for one post, reel, story, video or pin	1.5; Instagram stories and highlights 5; Rutube, Likee 3
`youtube_info`	Title, author, duration and formats with file sizes	2
`youtube_search`	Search YouTube videos, one page at a time	2
`youtube_download`	A temporary direct link: audio, or 144p to 2160p	15; 1440p and 2160p 25
`music_charts`	Shazam top chart for a country or the world	1
`get_balance`	Plan, credits left and rate limit	free
`list_supported_platforms`	Platforms, link forms and prices	free, no key

A call that fails costs 0.1, even for an unsupported link or one with no post or video id. A tool result is the same JSON the REST API returns.
