Mcp Stone

Overview

Mcp Stone is a Model Context Protocol server that connects AI assistants to Stone's open banking platform, enabling access to payments, Pix transfers, and banking operations through natural conversation. Any MCP-compatible AI model can invoke Mcp Stone's tools directly, letting the model decide when to execute banking functions during agent runs.

The server runs locally via the npm package @codespar/mcp-stone, communicating over stdio with your machine. You'll need to set the STONE_CLIENT_SECRET environment variable for authentication. The latest release is v0.2.2 under the MIT license, maintained at codespar/mcp-dev-latam on GitHub where it has 269 stars.

Mcp Stone appears in the AI & Agents category and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. Maintainers from codespar are welcome to claim this listing to verify ownership and keep information up to date.
