finslipa_merge · Finsliparn MCP: Risk & Policy

WHAT IT DOES

What finslipa_merge does on Finsliparn

AI agents invoke finslipa_merge to trigger actions in Finsliparn. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why finslipa_merge needs a policy

Merging a branch into main is a git operation that modifies the repository's main branch state. While reversible in theory (via revert), it triggers external VCS operations and can have significant downstream effects (CI/CD pipelines, deployments). It falls under Execute as it triggers an external VCS operation, and is high severity because inadvertently merging wrong code to main can break production systems.
