MCP Server Governance & Risk Check

Should this Model Context Protocol server be allowed in your environment, and under what controls? This applies the OWASP MCP Governance & Risk framework: four non-negotiable gates, a Tier 0-4 classification, and an eight-factor risk read.

The four non-negotiable gates

Any “No” blocks approval on its own — no risk score can override it.

Does the server have a named owner?
No owner = no approval
Is audit logging in place (for production use)?
No logging = no production use
Is the data/action scope documented?
No scope definition = no access
Is a periodic risk-tier review scheduled?
No review = no enterprise deployment
Classification tier

What is the most sensitive data or powerful action in scope? The bar rises with the tier.

1.Tool chaining

The framework's primary risk: can this server invoke other tools or trigger downstream workflows?

2.Access scope

What can the server actually do to your systems?

3.Credential handling

What does the server hold, and how?

4.Data sensitivity reached

How sensitive is the data within the server's reach?

5.Authentication & authorization

How strong is access control on the server itself?

6.Vendor / supply-chain trust

Where does the server come from, and is it pinned?

7.Auditability

Beyond the logging gate — how deep is the observability?

8.Human approval for irreversible actions

Is a person in the loop where it matters?

Answer the four gates, pick a tier, and score the eight factors — the verdict appears when everything is answered.

Maps to the standards you already report against

The OWASP MCP Governance & Risk Project aligns to the OWASP MCP Top 10, the OWASP LLM Top 10, NIST AI RMF, ISO/IEC 42001 and SOC 2 — so a decision recorded here drops into the frameworks your auditors expect.

Frequently asked questions

What is MCP governance?

MCP (Model Context Protocol) governance is the structured decision-making around whether an MCP server may connect to your AI agents, at what classification tier, and under what controls. The OWASP MCP Governance & Risk Project frames it as three layers — policy, controls and checklists — answering one question: should this server be allowed, and under what conditions?

What are the four non-negotiable MCP governance rules?

From the OWASP framework: no owner = no approval (every server needs a named owner); no logging = no production use (audit trails are mandatory in production); no scope definition = no access (the data and actions a server can take must be documented); and no review = no enterprise deployment (periodic risk-tier reviews are required). This tool treats each as a hard gate.

What are the MCP risk classification tiers?

The framework uses five tiers: Tier 0 (public data, read-only), Tier 1 (internal non-sensitive read), Tier 2 (sensitive read), Tier 3 (write-capable), and Tier 4 (privileged/critical). Higher tiers demand stronger controls and human approval, and the risk bar this tool applies rises with the tier.

What is the biggest MCP governance risk?

The framework names tool chaining as the primary risk: an MCP server that can invoke other tools or trigger downstream workflows can turn a single approved action into a chain the user never saw. Combined with write access and weak logging, that is where a governed MCP program most often fails.

Does this replace the OWASP MCP framework?

No. It is a fast triage that applies the framework's gates, tiers and risk factors so you can make and record a decision quickly. For the full guidance — inventory, classification, risk scoring and a 90-day rollout — read the OWASP MCP Governance & Risk Project itself.

This is a fast triage that applies the framework’s gates, tiers and factors. It is not a substitute for the full OWASP guidance or a formal risk assessment.
