Model Context Protocol · AEO & Agent Discovery

Unrust for AI agents, MCP clients, and answer engines

Every public guide, tool, and resource on Unrust exposes a clean Markdown twin (/index.md or Accept: text/markdown) and an unauthenticated Public Discovery MCP server so coding assistants can inspect worked code-review counterexamples, interactive tools, and diagnostic dimensions with zero API key.

Zero API Key · JSON-RPC 2.0 & REST

Public Discovery MCP & AI Snapshot

Query Unrust's public code-review challenges, 8 browser debugging explorers, and comparison guides immediately during any user chat.

  • POST https://unrust.dev/api/mcp/discovery
  • GET https://unrust.dev/api/ai/discovery
  • GET https://unrust.dev/resources/code-review-lab.json

Token-Efficient RAG · llms.txt v2

Markdown Mirrors for Every Route

Append /index.md to any public URL or send Accept: text/markdown to skip HTML chrome and read pure structured Markdown.

  • https://unrust.dev/llms.txt
  • https://unrust.dev/llms-full.txt
  • https://unrust.dev/.well-known/mcp.json

Claude Desktop / Cursor / Windsurf config

Add the local stdio MCP server or connect directly to the hosted SSE / HTTP discovery endpoints:

{
  "mcpServers": {
    "unrust": {
      "command": "npx",
      "args": ["-y", "unrust-mcp"]
    }
  }
}

Direct HTTP JSON-RPC 2.0 call (no key needed)

Any autonomous agent or HTTP client can call /api/mcp/discovery directly:

curl -sX POST https://unrust.dev/api/mcp/discovery \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"unrust_get_overview","arguments":{}}}'

Zero-key JSON-RPC 2.0 inspector

Inspect public MCP discovery calls

POST https://unrust.dev/api/mcp/discovery

Select a tool below to inspect the JSON-RPC 2.0 payload that AI assistants (Claude, Cursor, Windsurf, ChatGPT, Perplexity) exchange with Unrust's unauthenticated public discovery endpoint.

Fetch the 6 measured skill dimensions, 4 score bands, supported languages, and non-causal guardrails.
