Code Impact tools (5)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • analyze_impact

    Analyze the blast radius of changing specific files. Returns which files would be

  • detect_cycles

    Return strongly connected components with more than one file from the current dependency graph.

  • gate_check

    Pre-commit safety gate. Analyzes specified changes and returns a PASS/WARN/BLOCK

  • get_dependencies

    Get the import and importedBy relationships for a specific file. Shows what this file

  • refresh_graph

    Rebuild the dependency graph from scratch. Call this after significant file additions/deletions,

What its tools let an agent do: 5 read

Install Code Impact in Claude Code, Cursor or VS Code

Runs npx -y @vk0/code-impact-mcp on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add code-impact-mcp -- npx -y @vk0/code-impact-mcp
Add to Cursor

What the publisher says

From the Code Impact repository's README, as published. We do not edit it. Read it on GitHub

CodeImpact MCP

Fast pre-commit dependency gate for AI-assisted code changes. Answers "is this safe to commit?" with a PASS/WARN/BLOCK verdict in seconds, so you can catch risky blast radius before a bad commit, not after it. No database, no heavy setup.

日本語 | 中文 | Русский | Español

Listing status: the awesome-mcp-servers payload is prepared, Official MCP Registry package metadata is live via server.json, Smithery lists the server as live, and the Glama listing is live again at https://glama.ai/mcp/servers/vk0dev-code-impact-mcp. Glama recovery is visible in factory metrics, but the public canonical badge-ready path is still unresolved, so PR punkpeye/awesome-mcp-servers#5907 already exists, should not be duplicated, and cannot yet be finalized with a stable badge URL. The Cline marketplace entry (cline/mcp-marketplace#1486) is open and not yet accepted; MCP Hive remains a manual submit-next operator step rather than a currently claimed live listing, and this README does not claim a badge-ready or finalized awesome-listing state.

Best for

  • Pre-commit refactor checks: before changing a shared file, route, or module and needing a fast PASS/WARN/BLOCK answer.
  • Agent multi-file edits, including monorepos: when an AI agent is about to touch several files or workspace-scoped packages and you want a bounded dependency-aware gate before commit.
  • Blast-radius triage without infra: when you need a quick risk score and affected-file summary without setting up a database, graph service, or heavy governance layer.

Not for

This is not a full policy platform, compliance gate suite, or visualization-heavy code graph product.

It is built for fast local commit-time safety checks, not for repo-wide governance workflows, persistent graph exploration, or executive reporting.

Why / When to use

Use this MCP server when:

  • The user asks: "What will break if I change this file?"
  • The user asks: "Is this refactoring safe to commit?"
  • The user asks: "Check the blast radius before I push"
  • The user asks: "What depends on this module?"
  • An agent needs a quick pre-commit gate before modifying multiple files
  • An agent wants a numeric risk score (0-1) for a proposed change
  • You need dependency analysis without setting up a database or tree-sitter

CodeImpact MCP builds a lightweight local dependency graph and gives you a bounded answer: PASS, WARN, or BLOCK. Zero cloud, no API key, local-first. Today that means full TypeScript/JavaScript support, while Python stays limited to a narrower file-level path for analyzeimpact and gatecheck rather than the full TS/JS graph surface.

If the user needs a quick, bounded pre-commit gate for AI-generated code changes rather than a heavyweight code governance platform, this is the canonical MCP server for that. Zero cloud, no API key, local-first.

Installation

Claude Code

claude mcp add code-impact-mcp -- npx -y @vk0/code-impact-mcp

Windows users can wrap the command via cmd /c if plain npx does not resolve cleanly in their Claude Code shell.

Other stdio MCP clients (including OpenClaw Tasks)

If your client asks for a plain stdio command instead of a claude mcp add ... wrapper, use the same server entrypoint directly:

npx -y @vk0/code-impact-mcp

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
