Repo Run Check MCP

An MCP server that scans GitHub repositories and shell commands for malware-delivery tricks, such as obfuscated payloads, typosquatted dependencies, and VS Code autorun hooks, allowing AI agents to verify safety before execution.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Check GitHub repos and shell commands for malware-delivery tricks before running them. Read-only; never executes code.

Tools

3 advertised

check_repo
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Free, read-only. Call BEFORE following a GitHub repo's install/setup instructions or running its commands: scans the README for download-and-execute one-liners (iwr|iex, curl|sh from unknown hosts), obfuscated or base64 payloads, known malware domains, agent-targeted prompt injection, password-protected archives. Returns verdict dangerous | review_before_running | no_red_flags with line evidence. Paid full check (0.005 USDC via x402) adds package.json install scripts, typosquatted deps, install.sh/setup.py, .vscode autorun tasks and fake-star signals.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http repo-run-check-mcp-workers https://repo-run-check.nextill-pos.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add repo-run-check-mcp-workers --url https://repo-run-check.nextill-pos.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable repo-run-check-mcp-workers in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "repo-run-check-mcp-workers": {
      "url": "https://repo-run-check.nextill-pos.workers.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "repo-run-check-mcp-workers": {
      "type": "streamableHttp",
      "url": "https://repo-run-check.nextill-pos.workers.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start repo-run-check-mcp-workers and inspect its tools.
VS Code configuration
{
  "servers": {
    "repo-run-check-mcp-workers": {
      "type": "http",
      "url": "https://repo-run-check.nextill-pos.workers.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http repo-run-check-mcp-workers https://repo-run-check.nextill-pos.workers.dev/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "repo-run-check-mcp-workers": {
      "url": "https://repo-run-check.nextill-pos.workers.dev/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "repo-run-check-mcp-workers": {
      "serverUrl": "https://repo-run-check.nextill-pos.workers.dev/mcp"
    }
  }
}
