World Agent Web – Protocols for AI agents to discover and use web services

5•MerriBan•1h ago
Hi HN! I built WAW - an ecosystem of three protocols (HADP, ACDL, AWCP) that enables AI agents to discover and use web services through standardized manifests.

The Problem: Today, AI agents access web services through either: - Web search + HTML scraping (fragile, breaks when sites change) - Hardcoded custom integrations (doesn't scale)

Neither approach works well. Agents need a standardized way to discover what services can do and how to invoke them.

The Solution: WAW introduces manifest-based discovery (similar to robots.txt, but for agents): - Services publish a manifest describing their capabilities - Agents discover these dynamically at runtime - Type-safe invocation with JSON Schema validation - No hardcoded integrations needed

Think of it as: HTTP is to the World Wide Web what WAW is to the Agent Web.

Live Demo: - Working services: https://web-production-73c2.up.railway.app - Autonomous Claude agent: https://github.com/Fredbcx/waw/tree/main/demo - The agent discovers services, understands capabilities, and books restaurants autonomously

Positioning: WAW complements existing protocols: - MCP (Model Context Protocol): Desktop/local tool integration - A2A (Agent-to-Agent): Multi-agent collaboration - WAW: Web service discovery and invocation

They solve different problems and work together.

What I'm looking for feedback on: 1. Protocol design - does the spec make sense? 2. Use cases I'm missing 3. Integration patterns with existing systems 4. Whether this actually solves a real problem you have

The protocol is MIT licensed and designed to be community-driven. I see service registries (like Google for agent services) and micropayments (x402) as inevitable future infrastructure, but wanted to validate the core protocol first.

Links: - GitHub: https://github.com/Fredbcx/waw - Live site: https://web-production-73c2.up.railway.app - Spec: https://github.com/Fredbcx/waw/blob/main/docs/SPECIFICATION.md

Would love your thoughts!
