Overview

AI-generated overview

A data marketplace MCP server giving assistants paid access to US government and science datasets, including sanctions, SEC and CVE data, billed in USDC via x42

What you can do
Query a catalog of US government and science datasets, including sanctions, SEC filings and CVE records, through 21 tools. Retrieve sample data at a low per-call tier before paying for full results. Pay per request in USDC through the x402 payment scheme. Connect either to the hosted remote endpoint or run the npm package locally over stdio.
When to use it
Useful when an assistant needs structured public-sector or security data (sanctions lists, SEC records, CVE details) and you are willing to pay small per-request USDC charges rather than build your own data pipeline.
Requirements
Either the remote endpoint at api.osf-master-server.com or the local npm package osf-data-marketplace run with Node.js over stdio. A USDC-capable wallet or payment setup for x402 charges; no API keys or environment variables are declared.
Before you install
Requests are paid in USDC, so usage spends real money; the sample tier is cheap but full queries cost more. Payment credentials or wallet access are involved even though no keys are declared. Queries and any payment identifiers go to a third-party server. Verify pricing and data licensing before relying on results.

Installation

In SourceWeft

  1. Open Osf Data Marketplace in the dashboard and add it to a workspace.
  2. 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.onefreeman1337%2Fosf-data-marketplace/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

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
