Fork of tavily-ai/tavily-mcp with Copyright.sh licensing:

• automatic ai-license discovery
• optional x402-aware fetch (402 + payment-required: x402)
• usage logging to the Copyright.sh ledger

Tool names remain tavily-*. When following upstream install instructions, replace tavily-mcp with tavily-mcp-licensed and add the ledger env vars below.

Original repository: https://github.com/tavily-ai/tavily-mcp

This fork adds compliant licensing checks, optional x402 payment handling, and usage logging so developers can fetch content with clear rights and auditability.

1. Get a Tavily API key: https://app.tavily.com/home
2. Get a Copyright.sh ledger key: https://portal.copyright.sh
   • Sign up → complete onboarding → open API Keys → create a key (shown once)
3. Run:

env TAVILY_API_KEY=your_tavily_key COPYRIGHTSH_LEDGER_API_KEY=your_ledger_key npx -y tavily-mcp-licensed

4. Configure your MCP client:

{
  "mcpServers": {
    "tavily-licensed": {
      "command": "npx",
      "args": ["-y", "tavily-mcp-licensed"],
      "env": {
        "TAVILY_API_KEY": "your_tavily_key",
        "COPYRIGHTSH_LEDGER_API_KEY": "your_ledger_key"
      }
    }
  }
}

Required:

• TAVILY_API_KEY
• COPYRIGHTSH_LEDGER_API_KEY (needed for license acquisition + usage logging)

Optional:

• COPYRIGHTSH_LEDGER_API (default: https://ledger.copyright.sh)
• ENABLE_LICENSE_TRACKING (default: true)
• ENABLE_LICENSE_CACHE (default: false)

License-aware options (search/extract/crawl):

• fetch, stage, distribution, estimated_tokens, max_chars, payment_method

Unavailable policy:

• License denied or HTTP 401/403/402 results are returned with an unavailable reason and redacted content
• Unknown license remains best-effort

Note: Tavily's hosted MCP (https://mcp.tavily.com/mcp) does not include licensing. Use this fork locally for compliant licensing behavior.
