Blockfill

Overview

Blockfill is a Model Context Protocol server that executes crypto spot and perpetual trades across 11 venues with TWAP and maker order strategies. It keeps your API keys local on your machine, never transmitting them elsewhere, and exposes trading tools that AI assistants can invoke directly.

The server runs entirely locally via the uvx package manager with the command uvx blockfill. It requires no credentials to start and communicates with your MCP client over stdio. Version v1.2.1 is the latest release.

Blockfill lives in the Finance category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain Blockfill, claim this listing to verify ownership, earn the Verified badge, and keep information up to date.
