How to Use the Context Integrity Prover MCP in Cursor

Q: Can Context Integrity Prover prevent Cursor from editing the wrong files?

Yes, the validatecontextintegrity tool maps your scope boundaries. If the agent attempts to modify files outside those boundaries, the tool rejects the action.

Force Cursor to prove its code generation matches your original constraints before it edits your files.

Prevent drift in Cursor Agent Mode

The `validate_context_integrity` tool runs in Cursor Agent Mode to force the agent to verify its edits against your original constraints before saving changes. It operates directly inside your workspace to block drift before files are modified. Instead of waking up to a broken codebase, you get code that actually respects your boundaries. The agent checks its own work against the six-pivot trap, keeping your git diff clean and focused.

Reject out-of-scope edits in Cursor

By running `validate_context_integrity` inline, your Cursor agent catches unnecessary additions and strips them out before they hit your editor. This stops the editor from generating extra files or bloated helper functions. You don't have to spend time deleting hallucinated code. The tool ensures the agent's output matches your exact intent, keeping your project scope tight and manageable.

Map constraints using Cursor workspace config

The `validate_context_integrity` tool applies integrity checks to your entire workspace when configured in your Cursor settings. The agent uses this validation step to compare its proposed code changes with your project-level rules. This setup ensures that even complex, multi-file refactoring tasks stay aligned with your original architecture. Your agent won't make assumptions that break your existing codebase.

Setup guide

Set up Context Integrity Prover MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Context Integrity Prover MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Context Integrity Prover transactions." If the MCP tools are loaded correctly, Cursor will call the Context Integrity Prover tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "context-integrity-prover-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about Context Integrity Prover MCP in Cursor

Once added to your Cursor MCP config, the agent automatically calls `validate_context_integrity` during code generation tasks. It verifies that the proposed edits don't violate your project constraints.

Yes, the `validate_context_integrity` tool maps your scope boundaries. If the agent attempts to modify files outside those boundaries, the tool rejects the action.

You can configure it globally in your user settings or restrict it to a single project using a local Cursor MCP configuration file.

It forces your agent to prove it mapped your constraints, maintained scope, rejected out-of-scope items, prevented drift, validated assumptions, and matched your intent.

Your code schemas and validation constraints are processed in ephemeral V8 isolates. The server never writes your project rules to persistent storage, keeping your proprietary logic secure.
