Official Source Evidence is a Model Context Protocol (MCP) server: Accountless public-source, SEC Form D and OFAC tools with x402 USDC payment on Base. In practice that means any MCP-compatible AI assistant can call Official Source Evidence'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://evidence.regulavita.com/mcp/ and you're connected, with nothing to install locally. The current release is v1.1.0, with source at Joshua-Stapleton/official-source-evidence on GitHub.
Official Source Evidence is listed under Development 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.
