What you can do
  • Retrieve gold and precious-metal prices
  • Look up central-bank gold data
  • Read related macroeconomic data
  • All access is read-only, with no tools listed in the manifest
When to use it
Useful when an assistant needs current or historical precious-metal pricing, central-bank gold reserves or related macro figures for research, reporting or market commentary.
Requirements
A remote streamable HTTP endpoint at api.bullionapi.dev; OAuth sign-in is required. No environment variables or headers are declared.
Before you install
Access requires OAuth authorization of the client against the provider's account. The server is described as read-only, so no data is written or changed; no pricing, payment or secret handling is mentioned.

Installation

In SourceWeft

  1. Open Bullion API in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/dev.bullionapi%2Fbullion-api/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

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
