Why MCP security cannot be an afterthought
The Model Context Protocol standardizes how AI agents connect to tools and data, but the open protocol doesn’t include the security controls enterprise environments demand. These gaps are already being exploited.
No authentication
The MCP protocol does not specify how to verify the identity of a connecting agent. Research shows that 492 publicly deployed MCP servers have zero authentication, meaning any agent with network access can invoke exposed tools.
Prompt injection and tool poisoning
MCP servers are vulnerable to indirect prompt injection, where malicious content in tool responses manipulates agent behavior, and tool poisoning, where hidden instructions in tool descriptions override agent intent.
Over-permissioned access
A standard MCP server exposes every registered tool to every connected agent with permissions. There is no native mcp access control mechanism, no role-based policies, and no tool-level scoping. There is no way to restrict what a specific agent can read, write, or execute.
No audit trails
Agent interactions through MCP servers are not logged in a centralized, structured format. When a security incident occurs, there is no way to reconstruct what an agent did, which tools it invoked, or what data it accessed. For organizations subject to SOC 2, GDPR, or HIPAA, this creates regulatory exposure.
Enterprise-grade MCP security
Agen.co applies security to every Model Context Protocol connection, authentication at handshake, authorization per invocation, data protection per response, and behavioral monitoring across the session.
Complete MCP security across every attack surface
From authentication gaps to data exfiltration risks, Agen addresses every dimension of MCP server security, with identity, access control, and compliance built into the protocol layer.
Protocol-level security for every connection
Agen applies defense-in-depth at the protocol layer: authentication at handshake, authorization per tool invocation, data inspection per response, and behavioral monitoring across the session, not bolted on as an afterthought.
Harden any MCP server for production
Transform raw MCP servers into production-grade infrastructure. Agen wraps every endpoint in identity verification, scoped permissions, input validation, and egress filtering, closing the gaps that leave tools exposed to unauthorized agent access.
Identity-first verification for every agent
Close the authentication gap in the MCP protocol. Agen verifies connecting agents through enterprise identity providers, issues scoped credentials, and maintains identity continuity across sessions, so no tool invocation happens anonymously.
Fine-grained permissions per invocation
Enforce RBAC and ABAC policies evaluated in real time. Define what each agent can access down to individual tools, parameters, and data fields, preventing over-privileged access and eliminating the confused deputy problem.
Zero-trust boundaries for every agent
Scope tool visibility, restrict parameter values, and enforce context-aware policies so each agent operates within precisely defined boundaries, least privilege applied dynamically, not statically configured.
Deployments your security team will actually approve
TLS encryption, OAuth 2.1 authentication, input sanitization, and egress filtering applied automatically to any MCP server, so your security team can greenlight agent connectivity without custom hardening work.
Mitigate the top MCP threat vectors
Prompt injection, tool poisoning, token theft, data exfiltration, supply chain compromise, Agen's gateway inspects, validates, and monitors every interaction to detect and block these attack patterns before they reach your systems.
Compliance-ready agent governance
Map security controls directly to SOC 2, GDPR, and HIPAA requirements. Immutable audit trails, PII redaction, data residency enforcement, and consent management, the compliance infrastructure regulated industries need for AI agent deployments.
Stop sensitive data at the protocol boundary
Automatic PII redaction, field-level masking, and egress filtering applied to every tool response before it reaches the agent, preventing data leakage even if the agent itself is compromised or misdirected.
One enforcement point for your entire agent fleet
Route all agent-to-tool traffic through Agen's secure gateway, a single choke point where every connection is authenticated, every invocation is authorized, and every response is inspected before it passes through.
