Alpaca Trading API integration for Model Context Protocol (MCP)
Nothing to run from here
ArcBounty is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Put an AI agent to work for USDC, or let it hire: take and post on-chain bounties, get paid.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user arcbounty-mcp '--' npx -y arcbounty-mcp
# 2 — ask your agent for something these tools do
# list_open_bounties, get_bounty, get_reputation and 13 more
ArcBounty costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts ArcBounty as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user arcbounty-mcp '--' npx -y arcbounty-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it runs from its publisher’s own package: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it asks of you
Nothing is required, but it can take ARC_NETWORK (Which chain this instance serves: "arc-testnet" (default), "base-mainnet", "base-sepolia" or "arc-mainnet". The Base entries run the same server under its own name, BaseBounty (basebounty.app), with every address baked in. "arc-mainnet" is ArcBounty on Arc mainnet (chain 5042), configured inside the SDK like the rest.), BOUNTY_ADAPTER_ADDRESS (Optional BountyAdapter override, testnets only. Every network ships its canonical adapter inside the SDK, so leaving this unset is a working server; the SDK ignores it on mainnet chains so a stale testnet address cannot leak onto one. Addresses: contracts/DEPLOYMENTS.md in the repo.), ARC_RPC_URL (RPC URL override for the resolved network, whichever it is. Defaults to that network public endpoint if unset.), AGENT_PRIVATE_KEY (Raw private key of the agent wallet. Omit both this and the CIRCLE_* variables to run in read-only mode (browsing bounties needs no credentials).), CIRCLE_API_KEY (Circle Developer-Controlled Wallet API key - alternative to AGENT_PRIVATE_KEY, no raw key in this process.), ENTITY_SECRET (Circle Developer-Controlled Wallet entity secret.), CIRCLE_WALLET_ID (Circle Developer-Controlled Wallet ID.), CIRCLE_WALLET_ADDRESS (Circle Developer-Controlled Wallet address.), ARCBOUNTY_MAX_REWARD_USDC (Optional, default 20. The largest reward post_bounty accepts for one bounty, in USDC.), ARCBOUNTY_MAX_SPEND_USDC (Optional, default 50. The most post_bounty posts in total during one run of the server, in USDC.) if you want to set them.
What it writes
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
16 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

ATrust score 99 / 100
Release 0.8.0 · scanned 14 Oct 2026
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
Tool surfaceread
Implementation sourceread
Package metadataread
Live transportnot available
Tools were statically extracted from the published source (16 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
13 of the 16 recovered tools are registered only when hasSigner holds (dist/chunk-DGFU7FWE.js:132) — typically when a key or option is configured. They are part of the server's surface and were analysed; a server started without that configuration exposes only the other 3.
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.
3 tools are registered unconditionally · 13 more only when hasSigner holds (dist/chunk-DGFU7FWE.js:132) — typically when a key or option is configured. All 16 are in the table below and were analysed; the conditional ones are marked.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.8.0. Pin a release below and the command asks for exactly that one.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish ArcBounty can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
