Security Report
This MCP server acts as a stdio bridge to a remote Orbis API service, introducing significant trust and architecture concerns. The server proxies all MCP messages to an external HTTPS endpoint controlled by Orbis, meaning the actual tool implementations, authorization decisions, and API access controls are delegated to a third-party server rather than implemented locally. While the code itself is relatively clean and doesn't contain obvious malicious patterns, the architecture creates a fundamental security and transparency issue: users cannot audit what capabilities are actually available, how their wallet keys are handled server-side, or what data flows through the remote service. The environment variable handling for ORBIS_KEY (a wallet private key) is also concerning, as private keys should never be transmitted as HTTP headers. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

How payments work
Orbis uses the x402 protocol — an open HTTP payment standard built on Base. When your agent calls an API:
- Orbis returns a
402 Payment Requiredresponse with payment details - The MCP server handles the USDC payment on Base automatically
- The API call completes — total cost: $0.01
No wallets to configure for browsing. To make paid calls, provide your Base wallet via ORBIS_KEY.
Environment Variables
