Endpoint: https://doi-api.sendlabs.de/mcp · Streamable HTTP · stateless · no authentication required

The Doichain is a public blockchain with a built-in name-value store (a Namecoin descendant, merge-mined with Bitcoin). This server makes it usable for any agent that speaks the Model Context Protocol: Claude, ChatGPT, Cursor, VS Code Copilot and many more. Ask your agent in plain language, it picks the right tool itself:

"Anchor the hash of offer-2026.pdf on the Doichain."

"Did this contract already exist before October 1?"

"Are d/example or id/alice about to expire?"

"How is the Doichain doing right now?"

Opening the endpoint in a browser shows the landing page with setup instructions.

Quick start

Claude Code

claude mcp add --scope user --transport http doichain https://doi-api.sendlabs.de/mcp

Check with claude mcp list. Without --scope user the server only applies to the current project.

Claude (web and desktop)

  1. Open Customize → Connectors and click +.
  2. Choose Add custom connector, name it Doichain and paste https://doi-api.sendlabs.de/mcp.
  3. In a chat, enable it via + → Connectors.

Custom connectors also work on the free plan (one connector). On Team and Enterprise an owner adds it in the organization settings.

ChatGPT

Turn on Settings → Security and login → Developer mode, then create an app under Plugins → + with the URL above and authentication None. Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education.

Cursor

~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{
  "mcpServers": {
    "doichain": { "url": "https://doi-api.sendlabs.de/mcp" }
  }
}

VS Code (Copilot agent mode)

.vscode/mcp.json:

{
  "servers": {
    "doichain": { "type": "http", "url": "https://doi-api.sendlabs.de/mcp" }
  }
}
