Overview

AI-generated overview

A remote MCP endpoint for a CPI-pegged stablecoin aimed at AI agents, offering read-only tools plus a task board and self-registration.

What you can do
FlatCash is a remote MCP server for a stablecoin pegged to a consumer price index and intended for AI agents. The registry description mentions zero fees, a task board, and self-registration in about 30 seconds. Read-only tools are said not to require authentication, while other operations use a bearer token obtained through self-registration. No tool list is published in the manifest.
When to use it
Consider it if you want an assistant to interact with an agent-oriented stablecoin service, for example to read its data or take part in its task board. It is less relevant if you only need ordinary payment, banking, or market-data access.
Requirements
A remote streamable HTTP endpoint at flat.cash; nothing local to install. Read-only tools are described as not requiring authentication. Other operations need an Authorization header carrying a bearer token from self-registration.
Before you install
The server is financial in nature, so treat any action that moves, holds, or commits funds as spending real value. The Authorization bearer token is a credential; keep it out of logs and shared context. Read-only access is described as unauthenticated, but confirm what data is sent to the provider before use.

Installation

In SourceWeft

  1. Open FlatCash — Native Currency for AI Agents in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/cash.flat%2Fflatcash/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.
