Overview

Description from the maker (original English)

TPermanent memory layer for AI agents. Mint moments to the Polygon blockchain via MCP.

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: Search & AI memory

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Compared with others in Search & AI memoryi

  • More stars than 0% of the other 7277 servers in this category
  • Published to the registry more recently than 6% of the other 7277 servers in this category
  • Basic checks equal to or better than 100% of the other 7277 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 Hekkova MCP safe?

It passed 1 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 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 (1.0.0) 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. 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: Context7, Codebase Memory, Exa

Hekkova MCP Server

The permanent memory layer for AI agents. Connect any MCP-compatible AI (Claude, ChatGPT, Gemini, Cursor, custom agents) and mint moments — photos, videos, audio, text — permanently to the Polygon blockchain with IPFS + Filecoin storage, Lit Protocol encryption, and privacy tiers that let you control who sees what.


Quick Start

# 1. Install dependencies

npm install

2. Copy and configure environment variables

cp .env.example .env

Edit .env with your Supabase, Thirdweb, Pinata, and Stripe credentials

3. Seed the local test account and API key

npm run seed

4. Start the development server

npm run dev

→ Server running at http://localhost:3000/mcp


Connect with Claude Desktop

Add this to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{

list_momentsPaginated list of all minted moments. Filterable by phase, category, or search query.
get_momentFull details for a single moment by Block ID: CIDs, transaction hash, phase, tags, and more.
update_phaseChange a moment's privacy phase. Costs 1 credit (text/image) or 2 credits (video). Legacy Plan includes 10 free Phase Shifts/month.
export_momentsExport all moments as JSON or CSV. Returns a 24-hour download URL with all Block IDs and IPFS CIDs.

Running Tests

# Make sure the server is running in another terminal

npm run dev

Run the test client

npm run test-client


Deployment

Vercel (Serverless)
npm install -g vercel

vercel

Add a vercel.json:

{

"builds": [{ "src": "src/server.ts", "use": "@vercel/node" }], "routes": [{ "src": "/(.*)", "dest": "src/server.ts" }] }

Set all environment variables in the Vercel dashboard under Project → Settings → Environment Variables.

Railway
npm install -g @railway/cli

railway login railway init railway up

Set environment variables in the Railway dashboard. Railway will auto-detect the npm start script.

Fly.io
npm install -g flyctl

fly auth login fly launch

Fly will generate a fly.toml. Set secrets with:

fly secrets set SUPABASE_URL=... SUPABASE_SERVICE_KEY=... THIRDWEB_SECRET_KEY=...

fly deploy
