npx flatland-setup fl_live_…MCP plugin
For Claude Code and Cursor. The command above wires the MCP server into your agent — your existing assistant gets the full Flatland tool surface.

Fifty free answers, no card. Add one when you want more. Your model files stay on your disk; we don't store them.
Want to feel it first? Try the Workshop: a real compile runs against the engine without an API key.
Then: one command
$npx flatland-setup fl_live_YOUR_KEY_HERE
- → Validates your API key against
api.flatlandfi.com - → Detects Claude Code and/or Cursor on your machine
- → Writes the MCP server config automatically; no manual file editing
- → Runs a live end-to-end connection test
- → Confirms Flatland appears in your MCP client's server list
Open a new session and your agent has the Flatland tool surface. From there, describe a model. The agent compiles it. The engine returns typed bindings, assertion outcomes, and an Excel export.
Requirement: Node.js 18+. Claude Code or Cursor accessible from your shell.
Three ways to use Flatland
npx flatland-agentFlatland CLI
No Claude Code required. A standalone terminal agent scoped to financial modeling and quantitative reasoning. Bring your own LLM API key; the engine does the math.
POST api.flatlandfi.com/compileHTTP API
Programmatic. The same public endpoints every client uses — build models, compile, run sensitivity from any language.
Three things your agent can do next
flatland_compileCompile a typed model
Topologically sort the DAG, evaluate, run dimensional inference, return assertion outcomes. Bit-identical: same IR, same output, every time.
flatland_compile_scenarioOverlay a scenario
Sparse overlay against the base. Only changed assumptions differ. Diff the result against base to attribute output deltas to specific drivers.
flatland_sensitivityPropagate a sensitivity
Perturb one or more drivers, walk the DAG, return elasticity-ranked output deltas. Counts as one answer regardless of fan-out.
