Scope Guard
Enforce hard scope boundaries so your coding agent stays on the task and does not refactor unrelated files or drift into forbidden areas.
Overview
io.github.mdfifty50-boop/scope-guard is a Build-phase MCP server that enforces hard scope boundaries to stop AI agent drift.
What is this MCP server?
- stdio npm transport (scope-guard-mcp v0.1.3)
- Hard scope boundaries to block AI agent drift
- Useful for long autonomous sessions on monorepos or legacy codebases
- Complements qc-validator (quality) and secure-vault (secrets)
- GitHub: mdfifty50-boop/scope-guard-mcp
- Package version 0.1.3
- Transport: stdio
- npm identifier: scope-guard-mcp
What problem does it solve?
Agents wander into files, features, and refactors you never approved, burning time and risk on unrelated changes.
Who is it for?
Indie devs on tight tasks in large repos who need mechanical scope limits, not just prompt reminders.
Skip if: Exploratory research spikes where you intentionally want the agent to roam the whole codebase without limits.
What do I get? / Deliverables
After install, sessions respect enforced boundaries so work stays inside the scope you defined for that task.
- Enforced scope limits during agent sessions
- Reduced out-of-scope edits and refactors
- Configurable guardrails aligned with your repo
Recommended MCP Servers
Journey fit
Scope boundaries are configured when you set up agent tooling in Build and re-tightened whenever sessions grow during Ship review. Drift prevention is agent-tooling infrastructure—the guardrails around what tools and paths the agent may touch.
How it compares
Scope-enforcement MCP server, not a project-management or writing-plans skill.
Common Questions / FAQ
Who is io.github.mdfifty50-boop/scope-guard for?
Solo builders using Claude Code or Cursor who keep hitting agent drift on multi-file or monorepo projects.
When should I use io.github.mdfifty50-boop/scope-guard?
Use it when starting a bounded Build task or a Ship review session where the agent must not touch out-of-scope paths or domains.
How do I add io.github.mdfifty50-boop/scope-guard to my agent?
Install scope-guard-mcp 0.1.3 from npm, add the stdio MCP entry, configure your allowed scope rules per the repo README, and restart the agent.
