Project Summary

The WebMCP Tooling Suite addresses critical gaps identified in the MCP/WebMCP/LLMFeed ecosystem:

Gap	Problem	Our Solution
Trust Validation	No automated validator for LLMFeed cryptographic signatures	Full Ed25519 signature verification with public key fetching
Context Indexing	Prompt bloat from large tool catalogs degrades LLM performance	RAG-optimized indexing with 50%+ token savings
Feed Discovery	Fragmented, manual feed discovery across the web	Universal feed directory with .well-known URI support

Features

Implemented

• Universal LLMFeed Validator — Comprehensive validation from URL, file upload, or paste

  • Structural validation (feed_type, metadata, capabilities)
  • JSON Schema conformance checking
  • Full Ed25519 cryptographic signature verification
  • Security scoring (0-100) with actionable remediation guidance
  • Signature debugger for troubleshooting failed verifications

• Feed Discovery & Analysis — Discover feeds from any URL or domain

Security Model

The validator implements the full Ed25519 trust verification chain:

Feed → Trust Block → Public Key Hint → Signature Verification
         ↓               ↓                    ↓
    signed_blocks    Fetch PEM key      Verify against
    enumeration      from URL           canonical payload

Signature verification protects against:

• Tool Poisoning — Malicious tool definition modifications
• Tool Shadowing — Fake tools intercepting legitimate calls
• Supply Chain Attacks — Compromised feed distributions

Tech Stack

• Framework: React 18 + TypeScript + Vite
• UI: Radix UI primitives + Tailwind CSS v4 + shadcn/ui
• Storage: localStorage (default) + GitHub Gist sync (optional)
• Auth: GitHub OAuth (optional, via Cloudflare Worker)
• Crypto: Web Crypto API (native Ed25519)
• State: @tanstack/react-query + localStorage

Deployment

This is a fully static site that can be deployed to:

• GitHub Pages - Zero configuration needed
• Cloudflare Pages - Connect repo and deploy
• Netlify - Automatic deploys from GitHub

Optional: GitHub OAuth

For authenticated publishing to the directory, deploy a Cloudflare Worker:

# In a separate worker project
npx wrangler init webmcp-auth

Set these environment variables:

• VITE_GITHUB_OAUTH_URL - OAuth initiation endpoint
• VITE_GITHUB_TOKEN_URL - Token exchange endpoint
