All 14 tools / Agent files and MCP servers

Turn an MCP endpoint into ready-to-paste install snippets for five apps and confirm the server answers.

Install snippetsFreeFor agent builders and developers

Better than by hand

One snippet per app in each app's own format, checked against the live server, instead of five separate docs pages. We do not put a time on it.

Before: what you give it

The example input, as typed in. You give it a page address.

https://preflight.allthepossibles.com/mcp

After: what comes back

The first lines of a real run of the tool's own code on that input, fetched live when the sample was made, so the live page can differ from it. Nothing here is edited by hand.

Daily caps for every tool

Use it from your assistant

The tool is called mcp_install_snippets. Connect the server once, then ask for it by name or describe the job. Install steps.

claude mcp add --transport http toolbox https://toolbox.allthepossibles.com/mcp
curl -X POST https://toolbox.allthepossibles.com/api/mcp-install -H 'content-type: application/json' -d '{"url":"https://preflight.allthepossibles.com/mcp"}'

Try it here

The form starts with the same example input, so you can run it first and then swap in your own.
