About The Collaboration Tunnel
Mission
The Collaboration Tunnel (TCT) protocol establishes a new standard for efficient, verifiable content delivery to AI crawlers and automated agents. Our mission is to reduce global bandwidth consumption while improving AI content quality through standardized, template-invariant fingerprinting and conditional request discipline.
The Problem
Traditional AI crawlers fetch full HTML pages repeatedly:
- 103 KB average per page (HTML with templates)
- 13,900 tokens for AI processing
- 90%+ redundant fetches when content is unchanged
- No standard for machine-readable endpoints
- No verification of content authenticity
The Solution
TCT provides a 4-part protocol:
- Bidirectional Discovery – Verifiable C-URL ↔ M-URL handshake
- Template-Invariant Fingerprinting – SHA-256 content hashes
- Conditional Request Discipline – 304 Not Modified responses
- Sitemap-First Verification – Zero-fetch optimization
Measured Results
Based on 970+ URLs across 3 production websites:
- 83% bandwidth savings (103 KB → 17.7 KB)
- 86% token reduction (13,900 → 1,960 tokens)
- 90%+ skip rate for unchanged content
- 100% protocol compliance achievable
- 8,158 GWh/year potential energy savings
An Open, Royalty-Free Standard
The Collaboration Tunnel Protocol (TCT) is an open standard designed to build a more efficient and sustainable web for the AI era.
The core protocol, as defined in draft-jurkovikj-collab-tunnel, is and always will be available for anyone to implement under a perpetual, irrevocable, Royalty-Free (RF) license. There is no commercial licensing fee for implementing the TCT standard.
Our full, official IPR disclosure is available for public review on the IETF Datatracker:
https://datatracker.ietf.org/ipr/7074/
Our goal is to foster a vibrant, open ecosystem around a free and universal standard. The open-source reference implementations (WordPress, Cloudflare, Python) are provided to accelerate adoption.
Patent Status
US Patent Application 63/895,763
Filed: October 8, 2025
Status: Patent Pending
The provisional patent application covers the system and methods described in the TCT specification. Under the IETF Intellectual Property Rights policy (RFC 8179), a Royalty-Free (RF) license is granted to all implementers of the standard.
Open Source Implementation
Free Reference Implementations:
- WordPress plugin (GPL v2+) – Download
- Cloudflare Worker (MIT) – GitHub
- Python client library (MIT) – PyPI
- Complete documentation and examples
These implementations are provided under open-source licenses to accelerate adoption and demonstrate best practices.
IETF Standards Process
We’re pursuing standardization through the Internet Engineering Task Force (IETF):
- Specification: draft-jurkovikj-collab-tunnel-00
- Target: IETF 125 (March 2026)
- Working Group: GREEN (energy efficiency)
- IPR Disclosure: Royalty-Free (RF)
The energy efficiency section demonstrates:
- 0.06 kWh/GB network transmission savings
- 0.000187 kWh/token AI inference savings
- Scaled to 8,158 GWh/year at 10% adoption
Production Deployment
Live Sites (100% Compliant):
- wellbeing-support.com – 400 URLs, 10/10 score
- omacedonii.com – 45 URLs, 10/10 score
- bestdemotivationalposters.com – 500 URLs, 9/10 score
Total: 970+ URLs with full protocol compliance
