AI agent payment rail: earn, pay, trade in 152 currencies. Zero fees.
The publisher's own server: FlatCash — Native Currency for AI Agents
Overview
A local desktop MCP server from Flatcash that presents itself as an AI agent payment rail for earning, paying and trading across 152 currencies with zero fees.
- What you can do
- Acts as a payment rail an assistant can use for agent-driven money movement, described as covering earning, paying and trading across 152 currencies with zero fees. No tool list, instructions or README is supplied, so the specific operations, limits and data handling cannot be confirmed from the listing. It runs as a local process on the user's machine rather than a remote endpoint.
- When to use it
- Consider it only if you want an assistant to take part in payments or currency trading and you are prepared to verify the provider's terms, tool behavior and safeguards yourself, since the listing documents none of them.
- Requirements
- Runs as a local process on the user's desktop; the manifest declares no package, no authentication, no environment variables and no headers, so the actual runtime and any account or credential needs are undocumented.
Installation
In SourceWeft
- Open Flatcash Mcp in the dashboard and add it to a workspace.
- 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.
