Security Notes

• Keep tokens, API keys, and connection strings in the encrypted credentials vault.
• Do not allow arbitrary server URLs for remote MCP connectors.
• Mutating tools are approval-gated. Review the payload before executing them.

Troubleshooting

• If the health check fails, verify the token scope or credential payload and try again.
• If the tool list is empty, re-run sync-tools after storing the latest credentials.
