README

meta-data-mcp

A single MCP server that transparently routes user requests to 90 open-data sources.

`meta-data-mcp` is one MCP server — not many. Under the hood it bundles 90 *plugins*, each wrapping a different open-data API. The plugins are an implementation detail; from your LLM's perspective there is one server and one place to ask "where can I find data about X?"

You install one server. You get all the data, discoverable through built-in routing tools.

Why "meta"?

Finding open data isn't the hard part — there's an absurd amount of it available. The hard part is finding the right dataset *when you need it*. `meta-data-mcp` makes that automatic:

The LLM calls opendata_providers_find ("FX rates", "court rulings", "earthquakes near Lisbon") and the server routes the query against an internal registry of every bundled plugin.
The LLM then calls the matching tool directly. No setup step in between, no separate servers, no per-provider install rituals.

This project was forked from [opendata-mcp](https://github.com/OpenDataMCP/OpenDataMCP) and reshaped around the single-server idea once the catalogue passed a few dozen plugins.

Installation

You'll need `uv` (a Python package manager).

# macOS — install uv via Homebrew so MCP clients can find it
brew install uv

# Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows (PowerShell)
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Then register the server with every MCP client installed on your machine:

uv run meta-data-mcp setup

The command auto-detects which MCP clients you have installed and adds **one** `meta-data-mcp` entry under `mcpServers` in each. Supported clients:
