MCP

MCP (Model Context Protocol) connects Cursor to external tools through defined interfaces, enabling repeatable workflows beyond the repo.

When to use

• You need repeatable workflows that interact with systems outside the repo
• You need auditability (clear tool inputs/outputs)
• You want to reduce manual, error-prone steps

When not to use

• The workflow can be done safely in-repo without external access
• Tool access increases risk (production access, sensitive datasets) without controls
• The tool interface is not well-defined (risk of unintended side effects)

Useful guide (Infynno guardrails)

• Default to least privilege and prefer read-only tools.
• Require explicit approval for write/destructive capabilities.
• Ensure logs/audit trails exist for actions that mutate systems.
