Common questions

Is Vision6 MCP by usefulapi safe?

It passed 4 of 4 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 yesterday, and the latest version (1.16.3) reached the registry today.

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 Business and above.

What can I use instead?

In the same category: Inbox Zero, Agent-Native Chat, draw.io

Live endpoint: https://vision6.usefulapi.io/mcp · Homepage: https://usefulapi.io/vision6

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://vision6.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http vision6 https://vision6.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": { "vision6": { "url": "https://vision6.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 Vision6 credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/vision6/

On first connect you'll enter your Vision6 REST API endpoint and a REST-compatible API key (both shown in Vision6 under Integrations → API Keys).
