SignNow is an e-signature platform for uploading documents, preparing them for signing, sending signature requests, and managing templates and document workflows. It also offers AI-agent access to those workflows through an MCP server.
SignNow exposes a REST API at https://api.signnow.com authenticated with SignNow-issued API keys, OAuth bearer tokens, or in some cases a Basic Authorization Token, plus a hosted OAuth-protected MCP server at https://mcp-server.signnow.com/mcp.

Create a free developer account from SignNow developer signup, then open the API dashboard → Apps and Keys → select your application → API Keys and copy the API key. SignNow docs say to send it as Authorization: Bearer <API_key>.
Open the API dashboard → Apps and Keys → select your application → OAuth 2.0 and copy the Basic Authorization Token. SignNow uses this as the HTTP Authorization header with the Basic prefix, primarily to mint OAuth access tokens.
Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
