We Built a CCS-Native MCP Server — 6-Dimension Fail-Closed Verification in 10us

We Built a CCS-Native MCP Server

Today we launched correctover-mcp-server — an MCP server that embeds CCS 6-dimension runtime verification directly into the protocol layer.

Core idea: Every tool call is verified across 6 dimensions before execution. If any fails, the action is never executed (fail-closed).

The 6 Dimensions

Structure, Schema, Latency (P50<10us), Cost, Identity, Integrity.

MCP 2026-07-28 Modern-Only

No initialize handshake. No dual-era. Streamable HTTP + _meta version negotiation + resultType on every response + CacheableResult + subscriptions/listen SSE.

CCS Extension via server/discover

Broadcasts io.modelcontextprotocol/ccs with failClosed=true, maxOverheadUs=25.

3 Built-in Tools

ccs_verify, ccs_evidence_hash (Halo v0.2.30 compatible), ccs_status

Quick Start

git clone https://github.com/Correctover/correctover-mcp-server.git
cd correctover-mcp-server
npm install && npm run dev
