Overview

AI-generated overview

Flatland is a local MCP server providing financial reasoning infrastructure for AI agents, with typed models, deterministic compilation and receipts.

What you can do
Supplies financial reasoning infrastructure to an assistant, described as typed models, deterministic compilation and receipts. No individual tools are listed in the manifest, so the exact operations an assistant can call are not documented here. It runs as a local process on the user's machine over stdio.
When to use it
Consider it when you want an assistant to work with structured financial models and deterministic, receipt-backed reasoning rather than free-form answers. Because the tool list is undocumented, confirm the available operations before relying on it.
Requirements
A local runtime able to run the npm package flatland-client via npx (Node.js). A Flatland API key supplied in the FLATLAND_API_KEY environment variable, obtained from the provider's install page. Desktop only; not available as a web executable.
Before you install
Requires a live API key (FLATLAND_API_KEY) that grants access to your Flatland account; keep it out of shared logs and configuration. The server is financial in nature, so verify any outputs before acting on them. No tools are listed, so what it can read or change is unverified.

Installation

In SourceWeft

  1. Open Flatland in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
