Short answer
How can I check if my MCP tools follow MVA rules?
Your agent uses a validator to scan your tool definitions for Model-View-Agent compliance. You'll get a list of structural violations and specific fixes for your implementation. This ensures your tools stay predictable for your agent.
Audit outcomes
Where every issue lands.
The AI categorizes every structural flaw it finds during the audit.
CRITICAL
Breaking MVA rules
The agent flags tools that violate core structural requirements. You get a list of specific violations that prevent the tool from working in an MVA setup.
WARNING
Suboptimal patterns
The AI identifies logic that works but ignores best practices. These are areas where your tool might confuse an agent during complex tasks.
PASS
Compliant tools
The agent confirms which tools meet all structural standards. You can rely on these tools to behave predictably within your agentic workflows.
HUMAN
Manual logic fixes
The AI points out architectural mismatches that require your judgment. You decide how to refactor the code to meet the standard.
The workflow
What your AI does when the audit arrives.
The agent handles the heavy lifting of scanning your code and comparing it to the MVA standard.
Scan tool definitions
The agent reads your custom tool schemas to understand their structure and intent.
validate_mcpfusion_implementationCheck MVA alignment
The agent compares your tool's logic against strict Model-View-Agent structural rules.
validate_mcpfusion_implementationIdentify violations
The agent isolates specific points where your implementation fails to meet the required architecture.
validate_mcpfusion_implementationGenerate compliance report
The agent produces a clear summary of what passed and what needs your attention.

How this task behaves.
- 01
Can the AI fix my code automatically?
No. The agent identifies the errors and explains the violations, but you must manually edit your code to fix them.
- 02
Does the AI change my tool definitions?
No. The agent only reads your implementation to perform the audit. It cannot write to or modify your files.
- 03
What happens if a tool passes the audit?
The agent confirms the tool is compliant with MVA rules and marks it as safe for use in your agentic workflows.
- 04
Can I audit tools that aren't MCP-based?
No. This specific validator is built strictly to check MCP tool implementations against MVA standards.
- 05
Will the audit catch logic errors in my business code?
No. The agent checks for structural compliance with the MVA architecture, not for bugs in your specific business logic.
