Common questions

Is Corsizio MCP by usefulapi safe?

It passed 5 of 5 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 (1.19.0) 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?

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

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://corsizio.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http corsizio https://corsizio.usefulapi.io/mcp, then run /mcp to log in.

{

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

On first connect you'll paste your Corsizio API Secret Access Key (Account → Integration Settings; enable the API integration first).
