What kind of grids does this MCP support?

This MCP is specifically designed for 9x9 Sudoku grids.

Can it find specific errors in a Sudoku puzzle?

Yes, the validate_grid_state capability identifies specific rule violations like duplicate numbers in rows, columns, or boxes.

How do I use this with Claude or Cursor?

You connect your client to Vinkius once, and the MCP becomes available as a capability for your agent to call.

Does it check if a Sudoku is finished?

Yes, you can use the check_completeness capability to see if any cells are still empty.

Is there a way to look at a specific 3x3 box?

Yes, the get_box_coordinates capability provides the cell indices for any specific 3x3 sub-grid.

How do I check if my Sudoku grid is valid?

You can use the validate_grid_state capability by providing the 9x9 grid as a JSON string. It will return whether the state is valid and list any specific violations found.

Can this capability tell me if a Sudoku is fully solved?

Yes, the validate_grid_state capability returns an isSolved boolean which is true only if the grid is valid and contains no empty cells (zeros).

How can I find the coordinates for a specific 3x3 box?

Use the get_box_coordinates capability and provide the box index from 0 to 8 to get the row and column indices for that sub-grid.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Sudoku Grid Validator.

01
Get box coordinates
This capability maps a specific box index to its cell coordinates. It's useful when you need to isolate a 3x3 sub-grid for localized checks.
02
Validate grid state
This capability checks if a grid follows Sudoku rules. It identifies specific conflicts like duplicate numbers in rows, columns, or boxes.
03
Check completeness
This capability determines if any cells in the grid are still empty. Use it to see if a puzzle is ready for a final solution evaluation.

Real work

What teams actually run

Automated Puzzle Generation

An AI generates a new Sudoku puzzle and uses this MCP to ensure no rules are broken before presenting it to a user.

Solver Debugging

You use the capability to check if a custom Sudoku-solving script is producing valid completed grids.

Real-time Error Checking

An AI agent monitors a user's progress in a Sudoku game and flags invalid moves immediately.

Grid Completeness Verification

Check if a partially filled grid is ready to be evaluated as a finished solution.

One connector, every AI

Sudoku Grid Validator works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Sudoku Grid Validator to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.
