Connect to your AI in seconds.

Estimation Prover forces structured project planning before you commit to a timeline. This MCP validates estimates by forcing granular scope breakdown, identifying all technical unknowns and dependencies, mapping historical precedents, and applying concrete contingency buffers.

Stop guessing; start calculating.

What your AI can do

Validate estimation

Forces a structured review of your project plan, requiring scope decomposition, unknown mapping, historical comparisons, buffers, and explicit assumptions to validate any timeline.

Decomposing scope

Breaks large, vague tasks into small, manageable units that are easier to estimate.

Quantifying unknowns

Requires documentation of technical risks and external dependencies, noting the potential impact if they materialize.

Mapping history

Grounds current estimates in concrete data from similar projects completed in the past.

Calculating buffers

Adds a specific, measurable contingency time to account for known project volatility and cognitive biases.

Stating assumptions

Forces explicit definition of all resource limits, scope stability points, and external dependencies.

Included with Plan

The Pain of the Guessing Game

Right now, project planning often boils down to sticky notes on a whiteboard and optimistic meetings. You gather everyone in one room, throw around high-level tasks—'do feature X,' 'fix bug Y'—and someone suggests a timeline based on how fast they *think* things should go.

It feels productive, but it’s just vague scope that produces vague estimates. You leave the meeting with a date, but you haven't actually built anything; you've only documented assumptions and ignored every potential point of failure.

Estimation Prover: Getting an Accurate Timeline

With this MCP, the process is different. Your agent doesn't accept a date; it demands evidence. It forces you to break 'feature X' into discrete engineering tasks, map every technical risk like library deprecation, and reference exactly how long that specific thing took last year.

The result isn't just a number; it’s an auditable plan. You walk away with a verifiable timeline backed by historical data, quantified risks, and explicit boundaries.

What your AI can actually do with this

Project timelines are notoriously wrong. Developers and PMs tend to underestimate—a phenomenon called the Planning Fallacy. Estimation Prover acts as an immediate gatekeeper for any proposed timeline. It doesn't just calculate a date; it forces you through structured checks that expose blind spots in your plan.

Instead of giving one vague number like 'three weeks,' this tool demands you break the work into micro-tasks, documenting every potential technical risk and dependency failure point. You have to cite specific historical projects for comparison, not just say 'based on experience.' It also forces you to assign a numerical contingency buffer—a real safety net—and list every single assumption: Who's available? Does the API even work yet? If any of those things shift, your original estimate fails.

Connecting Estimation Prover through Vinkius lets your AI client enforce this rigor directly into your planning process. You get an objective verdict on whether a timeline is realistic or just wishful thinking.

Questions you might have

How does Estimation Prover validate an estimate? +

It analyzes the inputs based on a 5-pivot validation. You provide the task decomposition, risk mapping, historical context, buffer metrics, and assumptions. It rejects single-line guesses or projects without buffers.

What is the recommended buffer size? +

The tool enforces a minimum 20% buffer on projects with clear precedents, and increases to 40% or more for complex integrations, new frameworks, or systems with high architectural risk.

How does Reference Class Forecasting work here? +

It forces you to compare the new project with similar work completed in the past. If your past authentication integration took 3 weeks instead of the planned 1 week, you must adjust the new estimate's baseline accordingly.

How do I get started connecting Estimation Prover to my development workflow? +

You connect this MCP via your preferred AI client. Once connected, you can simply prompt your agent with a preliminary estimate for immediate validation. The system routes the scope data through the structured estimation process.

What kind of input does validate_estimation need to run correctly? +

The tool needs more than just a paragraph; it requires four distinct inputs: a task breakdown (decomposition), identified unknowns, specific historical references, and stated assumptions. It processes structured data points, not general text blocks.

Does Estimation Prover handle complex systems with multiple service dependencies? +

Yes, it analyzes dependency chains effectively. For optimal results, however, break the large system into functional micro-milestones first. This ensures each component receives detailed attention regarding its unique risks.

What should I do if my initial estimate contains circular dependencies? +

If a dependency loop exists (e.g., A needs B, and B needs A), the tool flags it immediately. You must manually break the cycle by defining an external service or temporary workaround to allow validation to proceed.

Is my proprietary project scope data secure when using Estimation Prover? +

Your input is processed within a secured, session-based environment. The MCP does not retain sensitive, unvalidated project details after the execution completes. Focus on providing the raw inputs for analysis.
