Process Restart (MCP Server Recovery)
Industry Definition Set • Entity Resolution Path: /glossary/mcp-process-restart-98
Quick Answer / TL;DR
Restarting a crashed or unhealthy MCP server process is handled by whichever process-supervision mechanism is in play (systemd, PM2, Kubernetes) — MCP itself has no restart or self-healing behavior, and a restart drops any in-flight sessions on that instance.
Key Takeaways
- Handled entirely by whatever process supervisor is in play — not an MCP mechanism itself.
- A restart drops any in-flight session on that instance; MCP has no session-resumption mechanism.
- Clients connecting to remote servers should handle reconnect (and possibly retry) logic defensively.
- Frequent restarts (a crash loop) usually indicate a real underlying bug worth investigating, not just tolerating via auto-restart.
Definitive Statement: Restarting a crashed or unhealthy MCP server process is handled by whichever process-supervision mechanism is in play (systemd, PM2, Kubernetes) — MCP itself has no restart or self-healing behavior, and a restart drops any in-flight sessions on that instance.
Technical Context & Protocol Usage
- Detailed Explanation
- This is really a consequence of the process-manager and process-monitor entries rather than a distinct concept: whatever's supervising the MCP server decides when and how to restart it after a failure. The MCP-relevant nuance is the same one raised in the disaster-recovery entry — a restart, however well-automated, still severs any currently open MCP session on that instance, and MCP defines no mechanism for a client to transparently resume where it left off on a fresh process.
Format & Payload Metadata
Format: Process-supervisor-specific
Latency: Not applicable to MCP directly — affects recovery time and drops in-flight sessions
Real-World Implementation Use Case
After a memory leak causes an MCP server to crash, Kubernetes automatically restarts the pod, but the team also investigates the leak itself rather than relying on restarts to mask the underlying bug.
