Privent wraps your MCP server as a transparent middleware layer. No code changes to your server or client. It intercepts tool call inputs, resource requests, and server responses, scoring risk and applying transformation before data crosses trust boundaries.
Agent issues tool calls via MCP
An MCP-enabled agent (Claude, or any MCP client) sends tool call requests and resource queries to your MCP server. The parameters and context accompanying each call may contain sensitive data.
Privent intercepts at the protocol layer
The Privent middleware layer sits between the MCP client and your server, transparent to both. It reads tool call inputs, resource access patterns, and response payloads without requiring any modification to your existing MCP implementation.
Risk scored, data transformed
ACARS scores each tool call in context of the session. APE masks or fragments sensitive fields. The server receives a clean request; the client receives a clean response. Full audit trail recorded per MCP session.
Add Privent to your existing MCP Servers pipeline without changing your architecture. One addition. Full graph-state visibility.
from privent import PriventMCPMiddlewarefrom mcp.server import Serverapp = Server("my-mcp-server")# Wrap your existing server; no other changesprivent = PriventMCPMiddleware(server=app,policy="enterprise",deployment_group="engineering")privent.run() # replaces app.run()
External gateways receive only the final prompt string. Privent reads everything in context, in real time.
Intercept all tool calls from Claude Desktop or Claude API clients before they reach your internal MCP servers, without modifying Claude or your server.
Detect when agents request MCP resources containing customer data, financial records, or internal documents, and apply masking before the response is returned.
Enforce organization-wide data protection across all MCP-connected agents from a single Privent deployment, with no per-server configuration needed.
We integrate in under 30 minutes. No orchestration changes required. Your pipelines keep running. Privent keeps watching.
