  "mcpServers": {
    "digital-defiance-mcp-debugger-server": {

06 · Debugger FAQ

What is Debugger?

This package is now maintained in its own repository: https://github.com/Digital-Defiance/mcp-debugger-server. It runs locally over stdio via the published package.

Is Debugger still maintained?

Yes - as of 2026-08-25, its last commit was 2026-03-28. We re-verify nightly.

How do I install Debugger?

Run `npx -y @ai-capabilities-suite/mcp-debugger-server`. The README documents 4 environment variables (MCP_DEBUGGER_TIMEOUT, MCP_DEBUGGER_AUTH_TOKEN, MCP_DEBUGGER_RATE_LIMIT…) to set first. Set MCP_DEBUGGER_TIMEOUT, MCP_DEBUGGER_AUTH_TOKEN, MCP_DEBUGGER_RATE_LIMIT, MCP_DEBUGGER_AUDIT_LOG before connecting. You can also paste the ready-made client config above.

Does Debugger run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
