ThinkNEO MCP Server
Open MCP server with built-in defense layer (ThinkShield). Part of the ThinkNEO Platform — enterprise AI governance.
      
---
What This Is
An open-source MCP server providing 72 tools for AI governance, observability, and security:
- ThinkShield — Production defense layer: detection engine, 5 rule packs, runtime middleware. 145 tests, p99 < 1ms.
- 72 MCP Tools — Governance, guardrails, FinOps, smart routing, observability, compliance, outcome validation, and more.
- 24 A2A Skills — Bidirectional MCP-A2A bridge for Google's Agent-to-Agent Protocol (v0.3.0, Linux Foundation).
- Apache-2.0 — Use it, fork it, contribute.
What This Is Not
- Not the full ThinkNEO Platform. Governance orchestration, cryptographic audit chain, tenant management, and enterprise integrations are proprietary and run at thinkneo.ai.
- Not a standalone security product. ThinkShield is the defense component of a larger governed platform.
Why Open
We open-source our defense layer because real security doesn't depend on hidden rules — it depends on tested, audited, continuously improved detection plus a strong governance moat around it.
Snort. Suricata. Falco. OWASP CRS. The security industry runs on open detection. We follow that tradition.
The detection is open. The governance is proprietary. That's where the moat is.
