Overview

Description from the maker (original English)

Shared knowledge cache for AI coding agents — reuse an answer once it exists.

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

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.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Common questions

Is Aieph 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 (0.1.0) reached the registry 2 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?

aieph

*your fix, everyone's gain*

aieph is a shared answer cache for AI coding assistants.

When an AI coding assistant is about to search the web, a small hook can quietly ask: *"Does someone already have the answer?"*

If the answer is already in the shared cache, aieph can return it right away — avoiding another trip to the web. If there is no answer, aieph simply gets out of the way.

MISS, timeout, or error? Nothing breaks. The original request continues as usual. That is the whole idea.

Your fix can become everyone's gain.

Why a shared cache?

AI coding assistants often look up the same kinds of things:

  • a familiar error message
  • a library's behavior
  • a configuration detail
  • a solution someone has already found

The first person does the searching. The next person doesn't necessarily need to. aieph gives those answers a place to be shared, and as more people use it, the cache can gradually become more useful.

It's still early, so a cache hit is not guaranteed. Sometimes aieph simply won't have the answer yet — and that's perfectly fine.

How it feels

AI assistant

│ │ "I'm about to search..." ▼ aieph │ ├── HIT → answer is already here │ └── MISS / timeout / error │ ▼ original search

aieph is designed to stay out of the way. There is no need to change how you work when the cache doesn't have something useful.

Getting started with Claude Code

Claude Code can use aieph with a single PreToolUse hook for WebSearch and WebFetch. A small setup looks like this:

git clone https://github.com/tryaieph/aieph.git

Then, in ~/.claude/settings.json, the relevant hook can look like:

{

"hooks": { "PreToolUse": [ { "matcher": "WebSearch|WebFetch", "hooks": [ { "type": "command", "command": "node /path/to/aieph/hook/aieph-cache.mjs" } ] } ] } }

That's it.

Requirements: Node.js 18+. No account or API key is required.

Optional environment variables:

AIEPH_API_BASE

LOOKUP_TIMEOUT_MS

Cursor support is being prepared.

Removing aieph

If aieph is no longer useful for you, removing the PreToolUse block is enough to return to the original setup.

What gets sent?

aieph is intentionally simple and transparent. Only the search query text is sent for matching. Nothing else is sent. There is no account to create and no personal profile to maintain. When there is no matching answer, the request passes through normally.

Local shared memory

aieph also includes a small local-only memory CLI in cli/. It is separate from the shared answer cache. The idea is simple: write a fact once, and let connected assistants remember it later. This memory stays completely local.

Early days, honest expectations

aieph is still growing. The shared cache is young, so there will be plenty of moments when it doesn't have an answer yet. That's intentional: aieph never needs to be perfect to be useful. A miss should feel exactly like there was no cache at all.

Over time, every useful answer someone discovers has the potential to help the next person.
