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
You need to fill in: Authorization

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.
You fill in yourself: Authorization

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

You need

Runs in the cloudNothing to install; it connects over the internet

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

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 memory https://mcp.worldku.com/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": {
    "memory": {
      "url": "https://mcp.worldku.com/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": {
    "memory": {
      "type": "http",
      "url": "https://mcp.worldku.com/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.

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

Your choice stays on this device in a cookie; no account needed.

Values you fill in

Authorization secret HTTP header
Worldku MCP access key as a Bearer token (create at worldku.com under Memory manager - AI tools). OAuth-capable clients can omit this and use the advertised OAuth 2.1 authorization server instead.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Worldku Memory 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?

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 (0.1.0) reached the registry 3 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

worldku-mcp

The official MCP server for Worldku memory. Save AI conversations into your Worldku memory and recall them back — from Claude Code, claude.ai, ChatGPT, Codex, Gemini CLI, or any other MCP client.

Full setup guide: [worldku.com/docs/mcp](https://www.worldku.com/en/docs/mcp) — step-by-step instructions for every client, authentication details, and troubleshooting. The same page in raw Markdown for AI agents: worldku.com/docs/mcp.md.

The fastest way to set up: paste this into your AI tool and let it walk you through —

I want to give you long-term memory with Worldku. Read

https://www.worldku.com/docs/mcp.md and walk me through connecting it, in

your own words.

Hosted service. The public endpoint is https://mcp.worldku.com/mcp. This repository is the open access layer only: the memory extraction pipeline, prompt rules, and platform services run on Worldku's infrastructure. Self-hosting this worker will not give you a working service — it exists for transparency and review, and connects to backends that require Worldku credentials.

Tools

Tool	What it does	Cost
`memory_overview`	Most recent memories, one line each (zero parameters)	1 read
`memory_search`	Semantic search over your memories	1 read
`memory_recall`	Filtered recall: time range / type / source, paginated	1 read
`memory_save`	Save the current conversation transcript for memory extraction	1 save

All tools fire only on your explicit ask — the tool descriptions instruct the model never to call them from ambient association. Saved transcripts go through Worldku's normal import pipeline: extraction runs asynchronously and new memories land in your memory workbench marked unread. Re-saving the same conversation is deduplicated server-side; extending a previously saved conversation appends only the new tail.

Connecting

Two authentication routes:

OAuth 2.1 — claude.ai and ChatGPT need no key at all: point them at the server URL and sign in at worldku.com when prompted.
Access key — CLI clients use a wk_mcp_… key, minted at worldku.com → Memory manager → AI tools. The key is shown once at mint time; up to 20 keys per account, each independently revocable.

Claude Code

claude mcp add --transport http --scope user worldku https://mcp.worldku.com/mcp \

--header "Authorization: Bearer wk_mcp_YOUR_KEY"

To keep the key out of the config file, export WORLDKU_MCP_KEY in your shell profile and use single quotes: --header 'Authorization: Bearer ${WORLDKU_MCP_KEY}'.

claude.ai (web, desktop, mobile)

Settings → Connectors → Add → Add custom connector → https://mcp.worldku.com/mcp → sign in at worldku.com. No key needed.

ChatGPT (web)

Enable Developer mode (Settings → Security and login), then create an app at chatgpt.com/plugins with the server URL and OAuth authentication. Sign in at worldku.com when prompted.

Codex CLI

export WORLDKU_MCP_KEY=wk_mcp_YOUR_KEY

codex mcp add worldku --url https://mcp.worldku.com/mcp --bearer-token-env-var WORLDKU_MCP_KEY

Gemini CLI

// ~/.gemini/settings.json — note the httpUrl field name

{ "mcpServers": { "worldku": { "httpUrl": "https://mcp.worldku.com/mcp", "headers": { "Authorization": "Bearer wk_mcp_YOUR_KEY" } } } }

Any other MCP client

Any client that supports Streamable HTTP with a custom header works:

URL: https://mcp.worldku.com/mcp
Header: Authorization: Bearer wk_mcp_YOUR_KEY

The config field holding the URL varies by client (url for most, httpUrl for Gemini CLI, serverUrl for some others) — a wrong field name usually makes the client ignore the server silently. More examples in examples/ and in the full guide.

Protocol

Native MCP revision 2026-07-28 (stateless Streamable HTTP): per-request metadata, no sessions, no SSE streams — every response is a single JSON object.
Dual-era: the 2025-11-25 initialize-handshake era is also served (still statelessly — no session ids, no SSE), because that is what current-generation clients speak. This leg will be dropped once the client ecosystem moves to 2026-07-28.
server/discover, tools/list, tools/call, and the Tasks extension (tasks/get / tasks/update / tasks/cancel) for async save polling. Clients that do not declare the extension get synchronous receipts instead.
OAuth 2.1 resource server per the MCP authorization spec: RFC 9728 protected resource metadata at /.well-known/oauth-protected-resource, audience-bound opaque tokens, memory:read / memory:write scopes. The authorization server (worldku.com) supports Client ID Metadata Documents and PKCE S256.
Discovery (SEP-2127 experimental): Server Card at /mcp/server-card, AI Catalog at /.well-known/ai-catalog.json.

Limits

200 reads and 50 saves per user per day (anti-abuse caps, reset at 00:00 UTC).
10 MB per request.
Reads and saves each book one usage action on your Worldku account. MCP access is included with every Worldku plan, including Free.

Development

Deployment (Cloudflare Workers) is done by the Worldku team — see wrangler.toml for the binding surface (no secrets live in this repo).
