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 Rocket-Harbor-420 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

Remote MCP server that quotes and delivers paid, read-only cross-chain snapshots for 1–5 public EVM addresses across four networks.

What you can do: Read open WorkMap community tasks and work pools, including public instructions and non-cash Harbor Points
Read the live price, supported networks, batch size and payment destination for a cross-chain report
Submit a transaction hash, payer address, address batch and wallet signature to redeem a report after manual payment
Reports return block numbers, EIP-7702 delegation indicators, contract-code sizes, SHA-256 fingerprints and explorer links per address and network
When to use it: Useful when you need a point-in-time technical snapshot of a few public EVM addresses across Ethereum, Base, Arbitrum One and Polygon, and are willing to pay a small stablecoin fee per batch. Not suited to balance checks, ownership or maliciousness judgments, or asset recovery.
Requirements: A remote streamable HTTP endpoint; no package, environment variable or header is declared. A wallet able to send 0.02 of a supported stablecoin on the chosen network, plus a personal_sign signature over the address batch, rail, network and transaction hash. Payment must reach 12 confirmations before the report is issued.

Before you install

Every report is paid, with no free preview or trial, and payment goes directly to the operator; the server never moves funds or signs payments. You must review the live quote and choose the network and asset yourself, and BSC-USD is not native USDT. Submitting a report sends a transaction hash, payer address, address batch and signature for verification; the signature authorizes only the report request.

Installation

In SourceWeft

Open Harbor Crew Cross-Chain Report in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Rocket-Harbor-420%2Fharbor-cross-chain-report/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Harbor Cross-Chain Report MCP

[Listed on Global A2A Registry] [MCP security grade A] [MCP Endpoint Check security grade A]

A dependency-free MCP server for the Harbor Crew report service, available as both a hosted remote MCP and a local stdio server. It requests read-only snapshots for 1–5 public EVM addresses across Ethereum, Base, Arbitrum One, and Polygon.

Each report batch costs 0.02 of the supported stablecoin on the selected network, paid directly to the operator. The six direct-payment rails are USDC on Ethereum, Base, Arbitrum One, or Polygon; USDT on Ethereum; and Binance-Peg BSC-USD on BNB Smart Chain. BSC-USD is distinct from native USDT. There is no free report preview or trial. get_payment_quote is available to read current payment instructions before a customer orders a report.

The report includes network block numbers, EIP-7702 delegation indicators, contract-code sizes, SHA-256 fingerprints, and explorer links. It does not inspect balances or private keys, prove ownership or malicious intent, or recover assets.

Tools

get_payment_quote reads the live quote and payment instructions. If you provide addresses, it formats the authorization-message template locally; it does not send those addresses to the quote endpoint.
submit_paid_report submits a transaction hash, payer address, address batch, and wallet signature to request the report after payment.

What the report contains

For each requested address and supported report network, the JSON includes the observed block number, EIP-7702 delegation indicator, code size, SHA-256 fingerprint, and explorer link. It is a point-in-time technical snapshot; it does not determine who owns an address, whether delegation is malicious, whether funds are recoverable, or whether an address has a particular balance. Every report is paid; no preview or trial is offered.

Payment and consent

Each paid report covers one batch of 1–5 public EVM addresses across Ethereum, Base, Arbitrum One, and Polygon PoS. The six payment rails are 0.02 USDC on Ethereum, Base, Arbitrum One, or Polygon PoS; 0.02 USDT on Ethereum; or 0.02 Binance-Peg BSC-USD (BEP-20) on BNB Smart Chain. BSC-USD is not native Tether USDt. Payment goes directly to the operator. The MCP server never initiates a transfer or signs a payment. A user must review the live quote and explicitly choose the network and asset before sending funds. The API requires 12 confirmations on the selected network and a personal_sign signature that binds the address batch, payment rail, network, and transaction hash; that signature authorizes only the report request and cannot move funds.
