Common questions
Is Apihubio MCP 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 (1.0.0) reached the registry 6 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: Spec Driven Development, Remote Desktop Commander, SuperCollider

Claude Desktop / Cursor / Codex
Add to your MCP config:
{"mcpServers": { "apihub": { "url": "https://mcp.apihub.io/mcp", "headers": { "Authorization": "Bearer ahk_your_api_key" } } } }
APIHub CLI
npx @apihubio/cli install # writes the MCP config for younpx @apihubio/cli register # get an API key npx @apihubio/cli topup 10 # fund with $10 USDC
Why credits instead of per-call x402
- Gasless: pay on-chain once when topping up, not per request
- Walletless: no USDC, no EIP-3009 signing, no gas
- Works in any MCP client: just a Bearer token header
- Instant: D1 debit at the edge, no block confirmations per call
