vector0-mcp

MCP server for Vector0 — precise, fast code editing for AI coding agents.

• Surgical edits — touches only what needs to change, never rewrites the whole file
• Auditable — every edit is tracked and logged
• Fast — sub-millisecond apply on typical files
• Safe — ambiguous edits are rejected, not silently misapplied
