Overview

Description from the maker (original English)

Live Cardano data (token prices, DEX trades, pools, wallets, NFTs, staking, governance). Read-only.

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: Crypto & blockchain
  • You need to fill in: X-API-Key

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.

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 realtap https://realtap.app/api/mcp --header 'X-API-Key: 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

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.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • search

    Find a Cardano token, liquidity pool, NFT collection, stake pool, ADA Handle, address, transaction, block or epoch by name, ticker or identifier. Use this first whenever you have a name or ticker rather than an exact id: each result names the tool to call next and the id to pass.

  • list_tokens

    Ranked list of Cardano native tokens traded on DEXes, for questions such as "top tokens", "biggest gainers today", "trending now" or "new pairs". Prices are in ADA and USD, volume and liquidity in ADA (24 h), market cap in USD, changes in percent. `rank` (default) combines market

  • get_token_liquidity

    Liquidity of one token. Depth: for each constant-product pool paired with ADA, the ADA that moves the pool's price 2 % up (buying) and the ADA received when selling moves it 2 % down, by the pool's own curve and fee (pools of other kinds, other pairings or without a fee are liste

Common questions

Is Realtap 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: X-API-Key

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 (1.4.0) reached the registry 14 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: Agent Data Tools: Prices and DeFi, Agent Data Tools: Chain data, Bellchain
