Safety Assessment

The Codex MCP Server is relatively safe for read-only access to blockchain data. The primary risk is the potential compromise of the Codex API key, which could lead to unauthorized data access. Ensure the API key is securely stored and managed.

Read-only access to blockchain data.
Requires an API key for authentication.
No direct write or delete operations.
Runs in stdio mode, limiting external exposure.

API key compromise could expose data.
Potential for data exfiltration if not properly secured.
Reliance on Codex API availability.
No explicit rate limiting mentioned, potential for abuse.
