Details
From the project READMEClearparty plugin for Claude Code
Clearparty checks a company before your agent pays, invoices or signs a contract with it. It resolves the legal entity in GLEIF, walks its parent chain, screens every company in the chain against the OFAC, EU, UN and UK sanctions lists, and validates EU VAT numbers in VIES.
This plugin adds two things to Claude Code:
- the Clearparty MCP server, with the tools
check_counterparty,validate_vatandscreen_sanctions; - the
clearparty-counterparty-checkskill, which tells the agent when to run a check and how to act on the result.
Install
You need Claude Code 2.1.292 or later and a Clearparty API key.
claude plugin install clearparty --marketplace clearparty/clearparty-plugin
Claude Code asks for your API key during install and stores it as a sensitive setting.
Get a key
Sign in at https://app.clearparty.dev/account/keys and create a key. It starts with cp_live_ and is shown once.
What is sent, and where
When the agent calls a tool, the plugin sends the tool inputs (a company name, LEI, VAT number or registry number) and your API key to https://mcp.clearparty.dev/mcp, and nowhere else. Clearparty's server then checks VAT numbers in the EU's VIES service, and may send the company name and candidate matches to its language-model provider (Anthropic) to resolve an ambiguous match or, when you ask for an AI summary, to write it. The plugin itself contains no code that runs on your machine.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
