Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "aibtcdev-aibtc-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@aibtc/mcp-server"
      ]
    }

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

license no standard license detected - usage rights unclear; check the repo before commercial use

npm package @aibtc/mcp-server - the @aibtc scope differs from the repo owner (aibtcdev); confirm it's the project's official package

registry namespace io.github.aibtcdev is GitHub-verified and matches the repo owner
