Overview

Description from the maker (original English)

Read and write knowledge-base articles, categories, snippets, glossary, readers, and search data.

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: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 24 things (tools) knowledgeowl_list_articles, knowledgeowl_get_article, knowledgeowl_list_categories, knowledgeowl_get_category …
  • The registry lists no key to fill in.

Which app do you use?

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

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker

Run this in your terminal

claude mcp add --transport http knowledgeowl https://knowledgeowl.usefulapi.io/mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "knowledgeowl": {
      "url": "https://knowledgeowl.usefulapi.io/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": {
    "knowledgeowl": {
      "type": "http",
      "url": "https://knowledgeowl.usefulapi.io/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.

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
SettingsConnectors1+ Create2https://…3

Menu names can differ slightly by plan and over time.

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

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

Common questions

Is KnowledgeOwl MCP by usefulapi safe?

It passed 3 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?

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 (1.36.3) reached the registry yesterday.

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

KnowledgeOwl MCP by usefulapi

Read and write your KnowledgeOwl knowledge base from Claude, Cursor, or any MCP client — browse and author articles, categories, snippets and glossary, and see reader search analytics.

Live endpoint: https://knowledgeowl.usefulapi.io/mcp · Homepage: https://usefulapi.io/knowledgeowl

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://knowledgeowl.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http knowledgeowl https://knowledgeowl.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "knowledgeowl": { "url": "https://knowledgeowl.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your KnowledgeOwl credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/knowledgeowl/

On first connect you'll paste your KnowledgeOwl API key — create one under Account → API keys. It's sent as HTTP Basic auth and runs against your account with your permissions.
