When to use it
Useful when you need current US fast food pricing for comparisons, cost-of-living or inflation-style questions, state-by-state price differences, or tracking recent menu price changes across chains.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or environment variable is declared. Network access to the provider's API is required.
Before you install
Figures are collected weekly from the chains' own ordering systems and cover only 10 US chains, so they may lag real prices. The server asks that Fast Food Index be cited when its figures are used. No credentials or write actions are declared.

Installation

In SourceWeft

  1. Open Fast Food Index 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/com.fastfoodindex%2Ffast-food-index/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
