Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account uantum for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Lets an assistant make non-custodial HTTP-402 crypto payments on behalf of AI agents through a 77-tool MCP server.

What you can do: A local MCP server that exposes 77 tools for non-custodial HTTP-402 crypto payments aimed at AI agents. It runs as a local process over stdio, so the assistant can call its payment tools directly from the user's machine. The registry description gives no further detail on individual tools or supported networks.
When to use it: Worth considering when an assistant needs to pay for HTTP-402-gated resources or services in crypto without handing custody of funds to a third party. Not useful if the assistant never needs to spend or transfer crypto.
Requirements: Runs as a local process over stdio, distributed as an OCI image (ghcr.io/udotcash/agents-u-cash-mcp:0.6.7), so a container runtime is needed. Desktop only; no web executable. No authentication, environment variables, or headers are declared.

Before you install

It moves cryptocurrency on the user's behalf, so funds can be spent and transactions are generally irreversible. The manifest declares no authentication and no environment variables, so how wallet keys or signing credentials are supplied is not shown; treat any key material as sensitive. Review the tool list before granting access.

Installation

In SourceWeft

Open agents.u.cash 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.

Tools

SourceWeft has not started this package in its sandbox yet, so its tools are not known.
