Flatland

Overview

Flatland is a Model Context Protocol (MCP) server: Financial reasoning infrastructure for AI agents: typed models, deterministic compilation, receipts. Because it speaks the Model Context Protocol, AI assistants can use Flatland as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package flatland-client speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need FLATLAND_API_KEY. The current release is v1.5.0.

On mcp.site, Flatland sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
