{
  "mcpServers": {
    "major7apps-pensyve": {
      "url": "https://mcp.pensyve.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

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.

runs as remote - your agent's requests go to mcp.pensyve.com

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

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

registry namespace io.github.major7apps is GitHub-verified and matches the repo owner
