How to Automate Evaluations with Claude — From Form Creation to Data Analysis in One Prompt

Connecting the evaluate.club MCP server to Claude Desktop lets you automate three core evaluation tasks with natural-language prompts: (1) creating scoring forms, (2) detecting judge bias, and (3) summarizing results. MCP (Model Context Protocol) is Anthropic's open standard released in 2025, designed to let AI assistants safely connect to real business systems. With a 5-minute setup and four practical prompts, you can cut evaluation admin time by up to 90%.

Why Claude + MCP Right Now?

4 Ways AI Is Transforming Evaluation Systems covered the principles — scoring automation, bias detection, continuous feedback, and transparency — but left a practical gap: "I get the concept, but what do I actually use?" As of 2026, MCP is the most pragmatic answer.

What makes MCP different from a regular chatbot is that it actually operates your system. Claude creates forms in evaluate.club, queries scoring results, and computes bias metrics on real data. Access is scoped by OAuth 2.1, so you're not handing your data over to a model — each call is an on-demand, authorized action.

Step 1 — Connect MCP to Claude Desktop (2 minutes)

Open Claude Desktop, go to Settings → Connectors, and click Add custom connector. Enter any name you like (for example, evaluate.club) in the name field and paste the URL below, then save.

https://mcp.evaluate.club/mcp

The first time you invoke the connector, a browser opens for you to sign in to evaluate.club and approve the requested scopes. Tokens refresh automatically every hour — no re-login required.

Step 2 — Create a Scoring Form by Prompt

Once connected, ask for a form directly:

Create a startup pitch competition scoring form. Criteria: team capability, market size, technical completeness, presentation. Weights 2:3:3:2, 100 points total.

Claude calls the create_form tool on the evaluate.club MCP, creates the actual form, and returns the dashboard URL. If the wording or weights aren't what you wanted, just follow up — "Rename presentation to IR persuasiveness and raise its weight to 3" — and the update_form tool is invoked automatically to modify the existing form. It's the evaluation form builder experience, but conversational.

Prompt example for editing an existing form:

Open the "H2 Competition" evaluation form I made last week. In the Team section, raise the weight of Capability from 2 to 3, and add a "Business sustainability" question.

Step 3 — Analyze Results in Natural Language

After judging closes, let Claude do the summary and bias work. Three prompts cover most cases:

(1) Top-team summary

Summarize the top 10 teams from the pitch competition by total score. One line each: team name, total, standout criterion.

(2) Bias detection

Compute each judge's mean and standard deviation, and flag anyone scoring notably higher or lower than peers.

(3) Pattern analysis

What do the lowest-scoring teams on 'presentation' have in common? Include judge comments in your analysis.

Claude pulls raw scores through MCP and computes bias indicators (deviation from trimmed mean) in its own reasoning. It's the same outlier logic covered in how to handle evaluator score errors, but you don't have to write the script yourself.

What AI Shouldn't Decide

MCP automates the administrative layer — aggregation, summarization, bias detection. Final winner selection and qualitative judgment still belong to human judges. As 3 methods to design fair judging criteria discusses, without a clear rubric even AI summaries lose credibility.

For sensitive evaluations (personnel, performance), we recommend restricting the OAuth scope to read-only (evaluate:read). The evaluate.club MCP grants write permissions selectively, so you can connect for analysis only and leave form creation or edits out of scope.

Get Started with evaluate.club MCP Today

MCP connection itself is free. Credits are only consumed when you actually create a form, so you can experiment with prompts on your existing starter credits. It's the shortest path from "evaluation automation as a future vision" to "evaluation automation as tomorrow's workflow."

Frequently Asked Questions (FAQ)

Q1: What exactly is MCP?

MCP (Model Context Protocol) is an open standard released by Anthropic in 2025 that defines how AI assistants connect to external systems and data safely. The evaluate.club MCP server implements this standard so Claude and similar AI clients can call capabilities like form creation, result retrieval, and bias analysis.

Q2: Is my evaluation data used to train the model?

No. MCP makes on-demand calls to evaluate.club only when Claude needs data, and the response is used only within that conversation. Anthropic's default policy is not to reuse Claude Desktop conversations for model training, and OAuth tokens are bound to your account.
