In the chat, type
@followed by the MCP server name and your instructions, e.g., "@elkassabgidataget the US unemployment rate series"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
ElkassabgiData MCP Server
A Model Context Protocol server that gives an AI assistant direct access to the three Elkassabgi data libraries: economic statistics, high-frequency US equity bars, and patent/innovation measures.
It runs as a Cloudflare Worker with a Durable Object per session.
Endpoint: https://elkassabgidata-mcp.elkassabgi.workers.dev/mcp
What it does
Eleven tools across the three libraries. The four browse tools work with no account at all; the data tools need a free API key (see below).
Tool | Library | Key needed |
| Econ | no |
| Econ | no |
| Econ | no |
| all | no |
| all | no |
| all | no |
| Econ | yes |
| HF equities | yes |
| HF equities | yes |
| IP / patents | yes |
| IP / patents | yes |
Every response carries the source's own licence with it, because the licence differs per source and honouring it is the user's obligation as much as ours.

Getting an API key
Free, instant, and one key works across all three libraries: https://hfdatalibrary.com/pages/download
The key is used server-side only and is never echoed back into the conversation.
