BlueRock MCP Security Fabric
Protect your agents, your tools, your data.
Secure-By-Default MCP
BlueRock MCP Security Fabric, running natively in the compute runtime, provides visibility and protection across every phase of the MCP attack path, enabling you to see and block attack events in real time.
Assume breach. Prompt filters and bolt-on security agents won’t stop attackers from reaching MCP servers or the data companies care about.
Protect every element of MCP. Block Agent/LLM escapes. Prevent shadow MCP. Control tool execution. Eliminate over-privileged access. Stop data exfiltration.
Gain broad visibility. Map agents → tools → servers → resource transactions. Detect configuration drift. Catch key leakage and credential-smuggling attempts.
Protecting
Agents
Agents run within strict guardrails. BlueRock Compute Firewall sandboxes each agent, denying command injection, remote command and control, unapproved binary execution, and access to sensitive local assets. Process isolation keeps behavior deterministic and policy-bound, while a secure-by-default runtime sees and stops high-impact paths. No surprises. No hallucination side effects.
Protecting
Tools
Tool access evolves fast. With new MCP servers comes new tools for clients to use. BlueRock Compute Firewall locks down tool access with configuration drift detection and strict allow-list governance. Client-to-tool manifests are protected, and MCP tool advertisements are controlled, preventing MCP from becoming power tools for attackers.
Protecting
MCP Servers
MCP servers are privileged bridges between agents and critical data, with the potential to boost user productivity and the attacker blast radius. BlueRock Compute Firewall secures MCP servers on two fronts. At the protocol edge, it stops MCP-to-agent API-key leakage and token-smuggling. In the runtime, it blocks OS command injection, remote shells, deserialization-based attacks, path traversal, SSRF, and binary drift. Precise CVE-agnostic guardrails shift MCP from a single point of failure to a hardened service platform.
Protecting
Data
The fastest path to data loss is the trust boundary between privileged MCP services and mapped resources. BlueRock Compute Firewall turns that boundary into an enforcement point. Building on agent and server protections, it applies deny-by-default resource access and enforces egress limits, seeing and stopping mass transfers. Only approved MCP services reach approved datasets over approved paths. Everything else is throttled or blocked
Limitations of AI gateways and security agents.
Prompt Filters
Many solutions focus on “prompt cleanliness” via AI gateways in front of LLM agents. That cover only the front door, the tip of the iceberg in an agentic AI architecture. While such gateways can filter obvious prompt-injection attempts, they do not address the inherent non-determinism of LLMs, which can still grant trusted or malicious users unintended access to MCP tools.
Emerging solutions treat agentic security like conventional runtime security, bolting on security agents to monitor LLM agents, observing behavior and flagging anomalies. That model fails for LLMs, whose logic is opaque and non-deterministic. The result is noisy alerts, complex policies, false positives that watch attackers instead of stopping them.

Product Components and Capabilities
The BlueRock MCP Security Fabric, built on the BlueRock Compute Firewall, provides a comprehensive, secure-by-default solution that ensures every component, from the AI agent to the MCP server and mapped data resources is secured, monitored, and controlled.
BlueRock CellBlock
A Secure AI client sandbox that restricts execution within the agent and MCP client runtime. CellBlock limits access to local resources and process execution outside the agent’s defined role. It also detects and prevents configuration drift. Running atop the BlueRock Compute Firewall, CellBlock inherits secure-by-default runtime protections, including defenses against arbitrary code execution and command injection.
BlueRock Sentry
Monitors and controls Agent-to-MCP and MCP-to-data interactions. Delivered via transparent application-runtime sensors for Python and Java, Sentry sees and stops Agent-to-MCP jailbreak attempts in real time, and controls which tools can execute within an MCP server. It also protects MCP-to-data resource interactions by preventing mass data exfiltration policy.
BlueRock Citadel
BlueRock’s secure-by-default runtime for MCP servers. Optimized for MCP workloads, Citadel sees and stops severe threat vectors including remote command-and-control (C2), remote code execution (RCE), command injection, container drift, path traversal, SSRF, privilege escalation and deserialization attacks.
BlueRock WatchTower
Provides centralized visibility into the configuration of all MCP Security Fabric components, alerting on configuration drift and on attacks detected or blocked. It delivers a comprehensive, shared-context view of agents, tools, servers, and data interactions across MCP.
