Stop Claude Desktop from falling back to raw Zod schemas

LLMs have no clue how the MCPFusion framework operates. Left to its own devices, your agent defaults to raw `z.object()` declarations that strip away vital features like hidden fields, timestamps, and guarded rules. Running `validate_mcpfusion_implementation` forces the client to use `defineModel()` instead, maintaining your data integrity. This tool acts as a strict gatekeeper on your local machine. It scans your active workspace, flags raw schemas, and blocks bad code before it ever touches your codebase.

Secure your data egress with automated Presenter checks

When your agent builds tools, it often tries to return raw database objects directly to the client. This leaks sensitive internal fields like password hashes or system IDs. Calling `validate_mcpfusion_implementation` ensures every single tool output is correctly wrapped in a Presenter. This guarantees your UI renders correctly and keeps your backend secure. The validator checks that you used `createPresenter` or `definePresenter` to filter outgoing payloads.

Correct API behavior inside this MCP Server

Your agent loves to use generic actions for everything. This wastes the platform's ability to cache safe reads or prompt users before destructive writes. By calling `validate_mcpfusion_implementation`, you force the model to categorize operations into queries, mutations, or actions. Safe reads get cached automatically, while mutations trigger confirmation prompts. It keeps your API predictable and prevents accidental data loss during autonomous runs.

Common questions about MCPFusion Developer Prover MCP in Claude Desktop

Open your `claude_desktop_config.json` file. Add the server under the `mcpServers` block with the required run command and arguments. Save the file and restart the desktop app to load the validation tool.

LLMs are trained on public data and have zero built-in knowledge of the proprietary MCPFusion pattern. Without this validation tool, your agent will write generic Zod schemas that break your MVA architecture.

Yes, you can run the server locally using stdio transport. It executes directly on your machine as a subprocess, allowing you to validate your code offline without sending data to external endpoints.

The tool returns a structured error payload containing self-healing suggestions. Your agent reads these suggestions, understands exactly which MVA rule it violated, and rewrites the code to fix the issue.

Completely. The tool only inspects your typescript AST structures and validation metrics locally on your machine. No raw source code or database schemas are sent to external servers, keeping your intellectual property safe.
