Whycant MCP

An MCP server that exposes the 'Why Can't We Have An Agent For This?' verdict engine, allowing agents to roast AI agent ideas directly from their IDE. It returns a verdict tier, agent-readiness score, top OWASP-MCP risk, and a shareable result URL. It supports anonymous usage with rate limits or token-based access for higher limits and additional tools like validate_idea and find_existing_agents.

roast_idea — Roast an AI agent idea
Advertised by the server during the last successful anonymous check.

Get the full whycantwehaveanagentforthis.com roast for an AI agent idea: the verdict tier, an agent-readiness score (0-100 + band), the top OWASP-MCP security risk, the "you're the X% who…" framing, and a shareable /result URL. Every call mints a real, persistent result page (its own OG share card) — so roasting from your IDE also publishes it. Anonymous (no token): 3/hour, 10/day. Add a token for higher limits.

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 whycant-mcp https://whycantwehaveanagentforthis.com/api/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 whycant-mcp --url https://whycantwehaveanagentforthis.com/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable whycant-mcp in your MCP settings.
