Taskhold

Remote MCP server config generator

Every agent client wants a remote MCP server written a little differently: a CLI flag here, url or serverUrl or httpUrl there, mcpServers or servers. Fill in the server once and copy the version for each client.

Runs in your browser. Nothing you type is sent anywhere. Still, don't paste real keys on shared screens.
