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.
Install
Get an API key.
Two minutes.
No card required. Your model files stay on your disk.
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 and assertion outcomes.
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.
What 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_sensitivityPropagate a sensitivity
Perturb one or more drivers, walk the DAG, return elasticity-ranked output deltas.
