Proof Inbox is a Model Context Protocol (MCP) server: Prepaid email-verify credits for MCP agents via Stripe Link. In practice that means any MCP-compatible AI assistant can call Proof Inbox's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://mcp.proofinbox.com/mcp and you're connected, with nothing to install locally. The current release is v0.1.1, published under the MIT license, with source at timdoes/proof-inbox-mcp on GitHub.
Proof Inbox is listed under Communication on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
