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 that this server's namespace belongs to honeycheck.xyz. It runs from a package rather than a hosted endpoint, so there is no endpoint to match against that domain.

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

Arc Treasury is a local MCP server that lets an assistant read USDC and EURC yields on Arc, Aave v4 and Morpho by deposit size, with some tools paid via x402.

What you can do: Read stablecoin yield data on Arc, including what USDC and EURC earn by deposit size, sourced directly from Aave v4 and Morpho. Use free tools without any wallet setup. Use paid tools that settle payment through x402 from a funded Circle Gateway wallet. Choose the chain where the wallet holds USDC (arc, base, arbitrum or hyperEvm) and cap the cost per call.
When to use it: Useful when comparing stablecoin lending yields on Arc, Aave v4 or Morpho at different deposit sizes, or when an assistant needs on-chain yield figures and can pay small per-call fees for premium data.
Requirements: Runs as a local npm package (arc-treasury-mcp) over stdio on a desktop machine. Optional PAY_CHAIN selects arc, base, arbitrum or hyperEvm (default arc). Optional PAY_MAX_USDC_PER_CALL caps cost per call (default 0.05). Paid tools need PAY_WALLET_KEY, the private key of a funded Circle Gateway wallet; free tools need nothing.

Before you install

Paid tools spend real USDC per call from the wallet behind PAY_WALLET_KEY, so set PAY_MAX_USDC_PER_CALL deliberately. The server asks for a wallet private key; anyone holding it controls the funds, so use a dedicated, limited-balance wallet. Review which tools are paid before running them.

Installation

In SourceWeft

Open Arc Treasury in the dashboard and add it to a workspace.
