Vantic is a Model Context Protocol (MCP) server: Verify an AI agent's payment authority: signed mandates, allowlists, and tamper-proof receipts. In practice that means any MCP-compatible AI assistant can call Vantic's tools directly — the model decides when to use them in a conversation or agent run.
It runs locally: the npm package @vantic/sdk speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.1.2, published under the Apache-2.0 license, with source at vanticlabs/vantic on GitHub.
Vantic is listed under AI & Agents 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.
