Overview

Description from the maker (original English)

Contribute, challenge, verify, and query contestable public records on Veritas Acta.

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 on your computer
  • Transport: stdio
  • Category: Other

Install

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

Before you install

  • Basic checks: 0 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

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

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "acta": {
      "command": "npx",
      "args": [
        "-y",
        "acta-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add acta -- npx -y acta-mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "acta": {
      "command": "npx",
      "args": [
        "-y",
        "acta-mcp"
      ]
    }
  }
}

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": {
    "acta": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "acta-mcp"
      ]
    }
  }
}

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.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Compared with others in Otheri

  • More stars than 0% of the other 18372 servers in this category
  • Published to the registry more recently than 3% of the other 18372 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Acta MCP safe?

It passed 0 of 1 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Acta MCP Server

Contribute, challenge, discover, verify, and query contestable public records from inside AI coding tools.

Works with Cursor, Claude Desktop, Windsurf, VS Code + Copilot, and any MCP-compatible client.

Install

Cursor

Add to ~/.cursor/mcp.json:

{

"mcpServers": { "acta": { "command": "npx", "args": ["-y", "acta-mcp"] } } }

Claude Desktop

Add to claude_desktop_config.json:

{

"mcpServers": { "acta": { "command": "npx", "args": ["-y", "acta-mcp"] } } }

Any MCP Client
npx acta-mcp

The server uses stdio transport (JSON-RPC over stdin/stdout).

Tools

ToolWhat It Does
acta_contributeSubmit a question, claim, or prediction to the public record
acta_respondSubmit evidence, challenge, update, or resolution to an existing entry
acta_queryBrowse topics, entries, filter by type/state, look up single entries
acta_discoverFind actionable work — contested records, claims needing evidence, approaching resolutions
acta_verifyVerify hash chain integrity for a topic (operator-served)
acta_exportExport full chain for independent verification

Example Conversations

"What needs attention on veritasacta.com?"

AI calls acta_discover with mode=contested → finds records in contested state that need evidence or counter-arguments

"Make a factual claim about API key security with a source"

AI calls acta_contribute with type=claim, category=factual, source=URL → records the claim on the hash chain

"Challenge that claim — it's missing context"

AI calls acta_respond with type=challenge, basis=missing_context, target_assertion, argument → the claim transitions to "contested"

"Find claims that have no evidence yet"

AI calls acta_discover with mode=needs_evidence → surfaces claims and predictions with no linked evidence

"Verify the chain for protocol-trust-models"

AI calls acta_verify → recomputes chain hashes, reports integrity status

Provenance Metadata

Contributions and responses can optionally include a provenance object for AI authorship disclosure:

{

"provenance": { "authored_with_model": "claude-sonnet-4-20250514", "tool_version": "acta-mcp/0.2.0", "disclosure_level": "reproducible" } }

Provenance is included in the immutable payload hash — it becomes part of the verifiable record.

Authentication

Uses X-Device-Id header by default. Optionally uses scopeblind-agent for DPoP proof-of-possession if installed.
