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 that this server's namespace belongs to api.gregswarm.duckdns.org, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

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 official open data as JSON: clinical trials, EU tenders, papers, apps, French companies, fuel prices and .com domains.

What you can do: Search ClinicalTrials.gov studies by condition, phase and status, returning only studies changed since the last run
Fetch new or changed EU public procurement notices from TED by CPV code, buyer country and keyword
Search OpenAlex scholarly works by keyword, year range and open-access status
Search Apple App Store apps by keyword and storefront country
Search France's company register by activity code, département, headcount and status
Check .com domain availability in bulk via Verisign RDAP
When to use it: Useful when you need structured, source-of-truth public data for research, market or procurement monitoring, or lead and domain checks, without building your own scrapers or API clients. The monitor tools suit recurring runs that should surface only what changed.
Requirements: A remote streamable HTTP endpoint; no local install. A RapidAPI subscription key is required and sent in the X-RapidAPI-Key header. Network access to the upstream open-data sources is handled by the server.

Before you install

The server requires your RapidAPI key, which may be tied to a paid RapidAPI plan or quota; check pricing and rate limits before use. Queries and filters are sent to third-party services through RapidAPI and the upstream sources. The monitor tools keep state between runs to report only changes.

Installation

In SourceWeft

Open Open data: clinical trials, EU tenders, companies, fuel prices in the dashboard and add it to a workspace.
Connect X-RapidAPI-Key credentials. They are stored privately and never shown on public pages.
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/org.duckdns.gregswarm.api%2Fopen-data/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
