How do I install SignSimple?

In Claude Code: claude mcp add --transport http signsimple 'https://signsimple.app/mcp' --header 'Authorization: <SignSimple API key as '\''Bearer ss_live_...'\'' — create one free at https://signsimple.app/profile. Optional for discovery and list_templates; required for sending and status tools.>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does SignSimple need an API key?

Yes. It expects Authorization, which you set in its configuration.

Who maintains SignSimple?

It is published by app.signsimple. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
