Bring your own keys

Some PluggedIn MCP tools call third-party APIs (image generation, YouTube research, web search). Instead of hosting your keys (and your bill) on our servers, you paste them into your local MCP client config. Every call sends them as request headers. We forward and forget.

We never store your keys. They live in your local config file (Claude Desktop, Cursor, etc), travel as encrypted-in-transit headers on each tool call, get forwarded once to the upstream provider, and are dropped from memory at the end of the request. Nothing is written to disk on our side. The form below runs entirely in your browser. Your input never leaves this page until you copy it into your own config.

1 · Paste the keys you want to use

Leave any field blank if you don't plan to use that tool yet. Adding more keys later just means rebuilding the config snippet below.
