Perplexity

Scope Decomposition Engine

The `validate_estimation` tool intercepts Cascade before it finalizes your project plan. It forces the agent to break down the scope into chunks no larger than two days. If Cascade tries to hand you a monolithic two-week task, the tool rejects it flat out. You get a mandatory reality check. Cascade has to map out the unknowns and apply a mathematical contingency buffer. You get a 20% tax for familiar work and up to 60% for novel features. It stops your IDE from feeding you the happy path.

Forcing Precedents in Windsurf

Developers suffer from systemic optimism bias. When Windsurf plans a new feature, this MCP Server demands a specific historical precedent. Not a gut feeling, but actual data from a past project. If you cannot cite a past example, the buffer requirement spikes. Cascade will state every assumption that must hold true for the deadline to survive. You see exactly where the project will fail before you write a single line of code.

Killing the Planning Fallacy

We all underestimate by 25 to 50 percent. This tool applies Reference Class Forecasting directly to your workspace. It calculates the Cone of Uncertainty based on your inputs and forces you to accept the worst-case scenario. There is no bypassing the math. The agent evaluates the risk multiplier and refuses to validate the estimate until the blind spots are documented. You stop accruing technical debt just to meet imaginary deadlines.

Setup guide

Set up Estimation 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 Estimation 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 Estimation Prover payment history." If connected, Cascade will call the Estimation Prover tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about Estimation Prover MCP in Windsurf

Open your MCP Servers UI under Settings, or edit the mcp_config.json file directly. Add the server details and click Refresh in the panel. Cascade auto-discovers the tools immediately.

You probably forgot to cite a historical precedent or your tasks exceed the two-day limit. The server enforces strict decomposition. Break the work down further and re-run the validation.

No. The mathematical constraints are hardcoded. If Windsurf tries to submit an estimate for novel work with less than a 40% buffer, the tool throws an error.

You document the unknown. The tool forces you to map that gap and automatically pushes your contingency buffer to the maximum threshold. It accounts for your ignorance mathematically.

Your project scope and task descriptions stay local to the Vinkius V8 Isolate Sandbox during validation. The server processes the text to calculate buffers and drops the state immediately after the run. Zero persistent storage.
