Axiomatic constraint for Windsurf

The `validate_first_principles` tool forces your agent to stop relying on pattern matching. By running your logic through a 6-pivot trap, it strips away the fluff that usually clutters your codebase. Windsurf chains this tool into your workflow to ensure every decision rests on verifiable math or physics. You get a solution that stands up to scrutiny because the agent couldn't take the easy way out.

Discarding analogical reasoning

Most agents copy what they see in existing repos. This MCP server blocks that behavior by rejecting common jargon and standard industry tropes. Once the agent triggers `validate_first_principles`, it must isolate fundamental truths. It stops copying and starts deriving, which changes how your project evolves under Cascade.

Cognitive pivot verification

The tool forces the agent to document every assumption it makes. If an assumption isn't grounded in hard logic, the tool rejects the path. Windsurf users see this in real-time as the agent pivots back to the drawing board. You aren't just writing code; you're building a verifiable logical chain.

Setup guide

Set up First Principles Prover MCP in Windsurf

Prerequisites

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

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the First Principles Prover MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my First Principles Prover payment history." If connected, Cascade will call the First Principles Prover tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about First Principles Prover MCP in Windsurf

It acts as a hard filter on the agent's reasoning. By forcing the model to solve from scratch, you avoid the drift that happens when agents just mimic existing patterns.

Yes. The tool forces the agent to ignore how others solved a problem and focus on the physics involved. It is specifically designed for high-stakes, custom architecture.

It adds a step to the reasoning process, which takes more tokens. You are trading raw speed for a higher degree of logical accuracy in your final output.

The server returns an error. The agent must then re-evaluate its logic until it can prove its premises are axiomatic rather than anecdotal.

The server only processes the logic fragments you send to the `validate_first_principles` tool. It does not store or train on your codebase, and Vinkius handles the secure, ephemeral connection.
