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 chomkaevan 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 returns a one-call natural hazard report for a US address or coordinates, including FEMA flood zone and hazard ratings.

What you can do: Check a US property's overall natural hazard risk and the factors driving it
Look up the FEMA flood zone, whether flood insurance is required, and seismic risk
Get ratings for wildfire, hurricane, tornado, heat, flooding, earthquake and other perils
See the county's disaster history and the county and census tract for the address
When to use it: Useful when evaluating, listing, insuring or researching a US property and you want hazard and flood-zone facts in one call rather than assembling them from several government sources.
Requirements: A remote Streamable HTTP endpoint; no account or API key is declared. The README describes paid tools billed a few cents per call in USDC through x402, with a local wrapper that needs a wallet private key and a per-call price cap.

Before you install

Paid calls spend real money in USDC; the README warns to use a dedicated wallet holding only a few dollars rather than a main wallet, and the wrapper asks for a wallet private key. Answers are informational, US-only, and not legal or insurance advice.

Installation

In SourceWeft

Open Property Risk Check 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.chomkaevan%2Fproperty-risk/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

Public Domain Check: MCP server

Is this book, film, song or artwork in the US public domain, and when does it enter it? This MCP server answers that question for AI agents. It's backed by:

2.38 million US Copyright Office registrations (1923–1977)
434,000 renewal records, linked to their registrations
the US copyright term rules

Paid tools cost a few cents per call, paid in USDC through x402. There's no account or API key.

Tools

Tool	Price	What it does
`check_public_domain`	$0.01 (brief) / $0.02 (full)	Returns the status (public domain, likely public domain, in copyright, or undetermined), the public-domain date, the confidence, a one-line reason and the record IDs. Full mode adds the complete reasoning and records. Includes HathiTrust's reviewer verdict when one exists; pass `countries` for the UK, EU, Canada, Australia, Japan, China or India. For 1923–1977 books, a title is enough.
`check_public_domain_batch`	$0.0075 per work (brief) / $0.015 (full)	Checks up to 50 works per call. Local wrapper only.
`search_copyright_renewals`	$0.01	Shows who renewed a work's copyright and when, which usually points to the rightsholder.
`copyright_rules_for_year`	free	Tells you which rule applies to a publication year, and whether a record lookup is needed.
`public_domain_day`	free	Lists what enters the US public domain on January 1.
`check_wallet_sanctions`	$0.002	Checks whether a crypto wallet is on the US Treasury (OFAC) sanctions lists (Bitcoin, Ethereum/EVM, USDT, USDC, Tron and more). Use it before paying an unknown wallet.
`screen_sanctions_name`	$0.003 / $0.005	Screens a person, company, vessel or aircraft name against the OFAC SDN and Consolidated lists, including aliases and spelling variants.
`check_property_risk`	$0.02 / $0.04	One-call natural hazard report for a US address: overall risk and what drives it, FEMA flood zone and insurance requirement, seismic risk, ratings for 18 hazards from FEMA's National Risk Index, and federal disaster declarations in the county since 2000.

You're never charged when a request is invalid or the service needs more information.

Brief answers by default. check_public_domain returns a short answer: the status, the date, the confidence, a one-line reason, and the record IDs. That's about 80% fewer tokens for your agent to read. For the complete reasoning and records ($0.02), pass format: "full" (local wrapper) or call check_public_domain_full (remote MCP).

Claude Desktop, Cursor, Windsurf, and other MCP clients

Add this to your MCP config:

json

{  "mcpServers": {    "public-domain-check": {      "command": "npx",      "args": ["-y", "public-domain-check-mcp"],      "env": {        "WALLET_PRIVATE_KEY": "0x...",        "MAX_PRICE_PER_CALL": "0.25"      }    }  }}

{  "mcpServers": {    "public-domain-check": {      "command": "npx",      "args": ["-y", "public-domain-check-mcp"],      "env": {        "WALLET_PRIVATE_KEY": "0x...",        "MAX_PRICE_PER_CALL": "0.25"      }    }  }}

WALLET_PRIVATE_KEY is the private key of a wallet that holds a little USDC on Base. Use a dedicated wallet with a few dollars in it, not your main wallet.
Without a key, the free tools still work.
MAX_PRICE_PER_CALL is a hard cap, in US dollars, enforced on your machine. The wrapper refuses any call that costs more.

Agents with built-in x402 support

These include @x402/mcp, Coinbase AgentKit, and other x402-aware frameworks. Connect to the remote URL above. Paid tools return an x402 payment request, and your client pays it and retries.
