Overview

Description from the maker (original English)

Compare engine claims, inspect dissent and check study evidence for student questions.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Games, sports, food & learning
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http ecca https://eccaai.com/api/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "ecca": {
      "url": "https://eccaai.com/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "ecca": {
      "type": "http",
      "url": "https://eccaai.com/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • ecca_synthesize

    Compare answers from configured engines and inspect disagreement, with lexical similarity and final-answer agreement when measurable.

  • ecca_pre_mortem

    Executes an adversarial pre-mortem identifying failure modes and early warning indicators using empirical argument verification.

  • ecca_decision_tournament

    Evaluates multi-option decision matrix using minimax regret and Pareto ranking over candidate pathways.

  • ecca_bts_divergence

    Measures lexical and semantic divergence across candidate assertions to penalize sycophancy.

  • ecca_refine

    Use one keyed tier-quota slot to sharpen rough student questions without adding facts; return detected niches and refinement chips. A closed engine ceiling falls back locally.

  • ecca_research

    Use one keyed tier-quota slot and dispatch-ceiling reservation to fetch and grade studies from scholarly indexes; return fetched evidence and explicit gaps.

  • ecca_verify

    Independently answer a question and compare the candidate against deterministic panel agreement. Show named dissent; spends one solve.

  • ecca_psychology

    Psychology research: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve.

  • ecca_learning

    Learning and study skills: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve.

  • ecca_nutrition

    Nutrition and supplements: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve.

  • ecca_money

    Money and business: refine the question, fetch studies, and show named claims before the verdict. Applies evidence and claims checks; spends one solve.

  • ecca_claim_protocol_validate

    Check one ecca.claim-protocol 1.0 document for shape: versioned, engine slots only (no vendor names), split causes from the published taxonomy, question text only with consent, seal present. Returns ok with the error list; validates shape, never the record behind it.

Common questions

Is ECCA safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 30 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Open Food Facts MCP, Modrinth MCP, Lichess MCP
