Every tool call. Governed. Sealed.
MCP is becoming the universal protocol for AI tool access — 4,000 servers, 341 confirmed malicious. Constrix intercepts every tool invocation before it executes, seals the outcome, and returns the decision in under 7ms.
Every tool request evaluated before it runs.
Your AI assistant can connect to databases, email systems, file stores, and external APIs. Without governance, it can call any of them at any time. Constrix intercepts every tool request before it executes — evaluating it against your policies and returning a decision in under 5 milliseconds.
- Zero code changes — works with any MCP framework or server
- Allow, restrict, deny, or kill any tool call by policy
- Every tool decision sealed and logged with a cryptographic proof
Every tool call — governed before it reaches your system.
How Constrix governs MCP
Transparent Proxy
No code changes in your agent or swarm. Point your MCP client at the Constrix proxy endpoint. Every tool call is governed automatically.
OWASP MCP Top 10
Every item on the OWASP MCP Top 10 is addressed structurally — from tool poisoning to supply chain attacks to excessive permissions.
CAPL MCP Chain Log
Every MCP call: server identity, tool name, parameters hash, agent identity, decision, and Ed25519 seal — in one auditable record.
Rate & Quota Limits
Define per-agent, per-tool, and per-tenant rate limits. Enforce daily quotas. Restrict bulk operations by policy. All without touching your agent code.
