Perplexity

Force realistic scoping in Cursor

Your AI agent uses `validate_estimation` to slice your code tasks into manageable units. This prevents you from overcommitting to massive features. By forcing this decomposition, the tool ensures you don't ignore the messy middle of a technical task. You get a plan that actually reflects the work ahead.

Mandate risk buffers in Cursor agent mode

The `validate_estimation` tool requires a specific buffer percentage for every estimate. You cannot ignore the reality of software development complexity. If the AI tries to estimate a novel task without a 40% buffer, the tool flags it. You force the agent to account for the inevitable setbacks in your code.

Ground your estimates in precedent in Cursor

Stop guessing how long a feature will take. The `validate_estimation` tool forces the agent to cite a real historical precedent for every estimate it creates. This removes the optimism bias from your workflow. You force the AI to compare your current task against actual, finished projects instead of abstract promises.

Setup guide

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 Estimation 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 Estimation Prover transactions." If the MCP tools are loaded correctly, Cursor will call the Estimation Prover tools automatically. You can also check Settings → MCP for a green status indicator.
