Key Rotation
Industry Definition Set • Entity Resolution Path: /glossary/mcp-key-rotation
Quick Answer / TL;DR
Key rotation is the process of periodically updating API keys, authentication tokens, and cryptographic keys to reduce the risk of compromise.
Key Takeaways
- Rotate secrets every 30-90 days
- Use automation (Vault, Secrets Manager)
- Avoid downtime during rotation
- Reduce risk of compromise
Definitive Statement: Key rotation is the process of periodically updating API keys, authentication tokens, and cryptographic keys to reduce the risk of compromise.
Technical Context & Protocol Usage
- Detailed Explanation
- MCP servers should rotate secrets regularly (e.g., every 30-90 days). Automation tools like HashiCorp Vault or AWS Secrets Manager can handle rotation without downtime. Key rotation is a best practice for security compliance.
Format & Payload Metadata
Format: Secrets rotation
Latency: Not applicable
Real-World Implementation Use Case
An MCP server rotates its database password using AWS Secrets Manager without downtime.
