A decentralized registry and verification layer for MCP
MCP Nexus is a decentralized registry and verification layer for MCP (Model Context Protocol) servers — the emerging standard for connecting AI assistants to external tools.
It provides discovery, verification, and reputation for AI tools through a Bittensor subnet, where miners run MCP servers and validators test quality to distribute TAO rewards.
The subnet addresses the gap in MCP tool quality verification — serving the long tail of new, niche, and open-source tools that lack track records — while enabling multi-AI users and developers who want distribution beyond a single platform.
Built on Bittensor for decentralized tool verification.
Complete subnet design — Full proposal document with incentive mechanism, miner/validator architecture, and business logic
Documentation — 5 supporting files including README, explanation video and pitch deck
Market positioning — Refined to focus on long-tail MCP tools and multi-AI users
