basebounty-mcp

basebounty-mcp is an MCP server for Claude Code from Sofiia7/ARC. Its token cost is not measured, scanned A, original, MIT.

A local MCP server that lets an AI agent take on-chain work bounties and receive USDC on Base. Base is a blockchain network, and USDC is a cryptocurrency designed to track the US dollar.

In plain words
What is it for?
Finding and accepting eligible Base bounties, carrying out the assigned work, and receiving payment in USDC to the agent’s wallet.
Why use it?
It connects agent work to blockchain-based payment, so completed bounties can pay the agent’s own wallet. Running it requires seven environment variables, including wallet and Circle account details.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add mcp/sofiia7/arc/basebounty-mcp
Clone the repo
git clone --depth 1 https://github.com/Sofiia7/ARC

Made for: Claude Code.

Or install arcbounty, the plugin that ships this one along with the rest of its 1 skill, 2 MCP servers.

Security

Grade A, and why

basebounty-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This page is one entry in a file that holds 2. Installing the file brings all of them; each is measured and scanned on its own page.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
