MCP Security & Governance
Real-time compliance & security enforcement for the agentic enterprise

MCP is where AI compliance obligations are won or lost

MCP has become the de facto standard for AI agent-to-tool integration. AI agents now autonomously invoke tools, read resources and act on enterprise data through MCP servers, shifting integration from deterministic API calls to dynamic, agent-driven interactions. But MCP adoption is outpacing governance — Gartner reports that 40% of developers cite security, privacy or regulatory concerns with AI-powered applications.

Unmanaged MCP adoption creates shadow integration paths that bypass enterprise controls. A single mis-scoped tool, an unpinned instruction set or a logging gap produces untraceable agent actions and no evidence trail to prove to a regulator or auditor which controls were in place, or that they held. The NSA and OWASP both conclude that the protocol's security posture depends entirely on implementation discipline, not on protocol guarantees.

MCP Governance: from Discovery to Enforcement

42Crunch enables enterprises to govern the MCP servers they expose to agents, partners and customers. It goes beyond discovering servers and identifying risks: it evidences compliance against the frameworks you are accountable to, remediates vulnerabilities and blocks non-compliant servers — ensuring only secure, approved MCP services reach production.

Capabilities include:

01
MCP Discovery

Auto-discover, register and inventory MCP servers. Generate an MCP Contract for every server.

02
MCP Audit

Score data, security and protocol against the 42Crunch Knowledge Base — a deterministic baseline.

03
MCP Scan

Drift and policy-conformance scanning. Identity, runtime and behavioral tests.

04
Runtime Governance

Enforce Security Quality Gates in CI/CD. Block non-compliant servers, close the feedback loop

Real-time compliance reporting against regulatory frameworks.

42Crunch continuously evaluates every MCP server against the regulatory and industry frameworks your organization is accountable to, and maps each individual finding to the specific control it breaches. Compliance posture is computed by the control itself on every audit and every scan — not assembled from documents at audit time.

Built for audit evidence, not simple dashboards.

The 42Crunch MCPG Security and Governance solution porivdes GRC and Security teams with comprehensive , versioned, reproducible, exportable records that hold up when someone external asks "prove this control was in place and that it worked."

Continuous evidence

Every audit, scan and Security Quality Gate decision produces a versioned, scored, framework-mapped record — not a point-in-time attestation.

Deterministic

The same server evaluated twice returns the same score, the same findings and the same verdict — not LLM-judged. Reproducibility is what makes a record admissible as audit evidence.

Finding-level traceability

Each finding carries a control reference, severity and remediation, so remediation effort maps directly to regulatory exposure.

Exportable reporting

Download compliance state reports for auditors, regulators and customer security reviews — without manual assembly.

Enforced, not advisory

Security Quality Gates block non-compliant MCP servers in CI/CD before they reach production.

Cross-framework compatible

Each finding is evaluated once and mapped simultaneously to every framework it touches (NIST AI RMF, OWASP MCP Top 10, EU AI Act, ISO 42001, CSA AICM), so GRC teams stop re-running a separate assessment per regulation.

Deterministic MCP security enforcement at scale

42Crunch generates an MCP Contract for each server: a machine-readable, declarative specification of how that server must operate — its authentication requirements, authorization policies, operational limits, what each tool is permitted to do, and which security controls must be enforced. Every contract is written against a common enterprise policy schema, so coverage is consistent across the entire estate while remaining specific to each server. This contract is the single source of truth across discovery, audit, scanning and compliance reporting — every server is evaluated against explicit, approved requirements rather than subjective assessment.

Continuous MCP discovery & risk
assessment

42Crunch continuously discovers MCP servers across the enterprise and generates an initial contract for each. Security teams gain an immediate inventory and risk assessment without waiting for developers to document servers manually.

Data sensitivity classification & risk-based access control

Each MCP tool is evaluated according to the sensitivity of the data it handles, the actions it performs and its actual response schema. Tools that modify data or perform high-impact actions are assigned a higher risk rating and subjected to stricter controls, including human-in-the-loop approval.

Continuous drift & OWASP MCP vulnerability detection

42Crunch continuously tests running MCP servers against their approved contracts, identifying OWASP MCP Top 10 vulnerabilities and unauthorized changes to tools, authentication, permissions, schemas, rate limits or runtime behavior before they expose connected agents and enterprise systems.

Audit-ready control traceability

Every security assessment and Security Quality Gate decision creates a versioned, scored governance record, providing evidence that required controls were evaluated and enforced.

MCP server vulnerability prevention

By validating tool definitions, inputs, credentials, permissions, isolation and delegated identity against the approved MCP Contract, 42Crunch blocks unsafe MCP servers before connection and detects drift or malicious changes after deployment. The matrix below represents the principal ways an MCP server can be manipulated, over-privileged or used to expose enterprise systems and data.

 

MCP VulnerabilityDescription
Tool PoisoningMalicious instructions embedded in tool descriptions that hijack LLM behavior.
Rug PullsDynamic replacement of a trusted tool definition with a malicious one at runtime.
Code & Command InjectionModel-provided inputs passed directly to shell, SQL, or system APIs without validation.
Credential LeakageAPI keys and OAuth tokens improperly stored, logged, or cached.
Excessive PermissionsOver-privileged tools violating least-privilege — one breach compromises everything.
Insufficient IsolationCross-tenant data leakage, shared service accounts, unsandboxed execution.
Confused DeputyToken passthrough allows an MCP server to be tricked into misusing user privileges.
