Every tool call. Governed. Sealed.
MCP is becoming the universal protocol for AI tool access — thousands of servers, no universal trust verification standard. 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. One environment variable. Full MCP governance active.
MCP Threat Coverage
Tool poisoning, supply chain attacks, server identity spoofing, excessive permissions, and prompt injection via tool responses — every major MCP attack vector addressed structurally at the proxy layer.
CAPL MCP Chain Log
Every MCP call: server identity, tool name, parameters hash, agent identity, decision, and Ed25519 seal — in one tamper-evident auditable record. The complete chain, sealed.
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.
