Axiomatic Reasoning in Vercel AI SDK

The `validate_first_principles` tool forces your agent to strip away industry jargon before generating a response. It ignores common patterns to ensure the output rests on logical foundations. Your UI updates in real-time as the agent processes these 6 cognitive pivots. By streaming the result, you show the user the exact moment the logic breaks away from flawed analogies.

Real-time Logical Validation

Connect this MCP Server to your Edge Functions to gate your logic. The tool requires the agent to define the problem in terms of physics or math, preventing shallow predictions. Developers can catch hallucinated reasoning before it hits the browser. If the agent cannot ground its answer in an axiom, the tool returns a failure state you can handle in your React component.

Strict Cognitive Constraints

Use the `validate_first_principles` function to force your agent to restart its reasoning chain if it relies on buzzwords. It acts as a hard filter on your model's output stream. This is for when your application demands original solutions. By forcing the agent to build from zero, you get higher quality results for complex engineering or design tasks.

Setup guide

Set up First Principles Prover MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all First Principles Prover tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent First Principles Prover transactions",
});

console.log(text);
await mcpClient.close();

Common questions about First Principles Prover MCP in Vercel AI SDK

Install the MCP client via npm and initialize it within your route handler. Pass the `validate_first_principles` tool into your generateText call to force axiomatic reasoning during the request.

Yes. The tool results stream directly into your UI components. You can show the user the reasoning process as it occurs.

Absolutely. It works with Edge Functions, provided you manage the connection lifecycle correctly. Always close the client after the operation finishes.

The tool is designed to reject analogical reasoning. If the agent cannot ground its answer in fundamental truths, it will fail the 6-pivot test.

The server only processes the specific logic strings you send for validation. No persistent storage of your inputs occurs within the ephemeral environment.
