Lets AI assistants (Claude Desktop, Cursor, Windsurf, or any MCP-compatible host) discover, purchase, and verify content licenses autonomously — mid-conversation, without opening a browser. Every license is registered on-chain (Tempo blockchain) with cryptographic proof.

Unlike generic search APIs, Opedd returns content with a verifiable license key — defensible under the EU AI Act and any copyright jurisdiction.

Quick start

npx opedd-mcp

Then add it to your MCP host (see Claude Desktop / Cursor / Windsurf setup below). Discovery + verification tools work with no configuration; purchasing and content retrieval use optional API keys from opedd.com.

Hosted endpoint — no install (mcp.opedd.com)

Prefer zero-install? The same 17 tools are served hosted at https://mcp.opedd.com/mcp (Streamable HTTP). Auth is an Authorization: Bearer header with any Opedd key — public discovery tools need no auth at all.

Claude Messages API (production agents):

{
  "mcp_servers": [{
    "type": "url",
    "url": "https://mcp.opedd.com/mcp",
    "name": "opedd",
    "authorization_token": "opedd_buyer_live_..."
  }]
}

OpenAI Responses API:

{
  "tools": [{
    "type": "mcp",
    "server_label": "opedd",
    "server_url": "https://mcp.opedd.com/mcp",
    "authorization": "opedd_buyer_live_..."
  }]
}

claude.ai / Claude Desktop custom connector (all plans): Settings → Connectors → Add custom connector → URL https://mcp.opedd.com/mcp; add a Authorization: Bearer <your key> request header for the credentialed tools.

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "opedd": {
      "url": "https://mcp.opedd.com/mcp",
      "headers": { "Authorization": "Bearer ${env:OPEDD_KEY}" }
    }
  }
}

Key routing: opedd_pub_* → publisher tools · opedd_buyer_* → content retrieval · ent_* → bulk feeds · buyer-portal JWT → audit/compliance/EU-AI-Act tools. Your key is forwarded per request and never stored by the gateway.

What it does

Exposes up to 17 tools to any AI assistant (some are conditional on env vars):

Always available — discovery + per-article purchase + onboarding + rights signaling
