KarmaDue
Provides pre-install checks for npm packages: agents can call check_install with ecosystem "npm" (or the karmadue-guard shim can intercept npm/npx installs) to get a verdict on a target package—a known trap with tested fix steps (fix_first), a warn, a deny for a malicious-package report, no_known_issues, or unknown—along with dated test records and supporting fix recipes.
Provides pre-install checks for pnpm installs via the karmadue-guard shell shim, which wraps pnpm so that a package is evaluated against known install traps and malicious-package reports before it is installed, returning tested fix steps or a warn/deny/no_known_issues/unknown verdict.
Provides pre-install checks for yarn installs via the karmadue-guard shell shim, which wraps yarn so that a package is evaluated against known install traps and malicious-package reports before it is installed, returning tested fix steps or a warn/deny/no_known_issues/unknown verdict.

Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@KarmaDuebefore I install tailwindcss@4 with npm, check for known traps"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
KarmaDue
A pre-install check for AI agents. Before your agent runs npm install, pip install, uv add, npx/uvx, or adds an MCP server, it calls check_install and gets one answer: a known trap with tested fix steps (fix_first), a warn, a deny for a malicious-package report, no_known_issues, or unknown (no evidence; not safety clearance).
Read-only. Nothing runs your command.
No account or key for reads. Anonymous limit: 30 requests/hour per IP.
Every fix cites a dated test record. Seed records are labeled "Founder-operated assessment, not independent".
Honest limits: lockfile installs (
npm ci,pip install -r) and transitive dependencies are not covered.
