## Description
Statistics Iceland (Hagstofa Íslands) PxWeb MCP. Keyless.

## Tools
Capabilities this server exposes over MCP:

- **subjects** — Navigate the database/subject tree. Root lists databases; sub-paths list folders (type "l") and tables (type "t", id ends in ".px").
- **table_meta** — Table definition (dimensions, valid values). Path must include the ".px" table suffix.
- **query_table** — Pull data from a table (path includes the ".px" suffix). body is a PxWeb query object. PxWeb limits request size — filter dimensions to keep the cell count small.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

```json
"mcpServers": {
  "hagstofa-is": {
    "command": "npx",
    "args": ["-y","@pipeworx/mcp-hagstofa-is"]
  }
}
```

## Documentation

## What Hagstofa Is MCP server does

Hagstofa Is MCP server connects MCP-compatible agents to Statistics Iceland’s PxWeb data service. The server provides three pack-specific tools: `subjects` for navigating the database hierarchy, `table_meta` for reading a table’s schema, and `query_table` for retrieving data.

The source organizes content as databases, folders, and tables. A table is identified by a path ending in `.px`. Agents can first explore available subjects, then inspect a selected table’s dimensions and permitted values before constructing a query. This sequence helps callers use the correct codes and keep requests within PxWeb’s limits.

## How it works

Hagstofa Is MCP server accepts MCP tool calls through either the hosted Pipeworx endpoint or a local process. The hosted endpoint is available at `https://gateway.pipeworx.io/hagstofa-is/mcp`. Its `tools/list` response includes the three Hagstofa tools and shared Pipeworx gateway tools, so the visible tool count is larger than the pack-specific list. The gateway also exposes `ask_pipeworx`, which can route natural-language questions across the wider Pipeworx catalog.

The local package communicates over standard input and output and exposes only the Hagstofa pack’s tools. Both modes use the same underlying source and do not require an API key. Direct HTTP tool calls are also documented through the gateway’s `/v1/tools/` endpoints.

## Setup and configuration

For a hosted connection, add the MCP URL to a compatible client:

```json
{
  "mcpServers": {
    "hagstofa-is": {
      "url": "https://gateway.pipeworx.io/hagstofa-is/mcp"
    }
  }
}
```

For local stdio use, run the published package with `npx`:

```json
{
  "mcpServers": {
    "hagstofa-is": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-hagstofa-is"]
    }
  }
}
```

The material does not specify environment variables or additional configuration. The hosted gateway does not require an account for its first calls, while the local mode avoids the gateway and its account requirements entirely.

## Tools and capabilities

- `subjects`: Lists databases at the root and folders or tables below a selected path. Folder entries use type `l`; table entries use type `t` and end in `.px`.
- `table_meta`: Returns a table definition, including dimensions and valid values. Its path must include the `.px` suffix.
- `query_table`: Retrieves table data using a PxWeb query object. Its path also requires the `.px` suffix.

A practical workflow is to find a table with `subjects`, call `table_meta` to identify valid dimension values, and then submit a narrowly filtered `query_table` request.

## Limitations and notes

PxWeb limits request size. Queries should filter dimensions so the requested cell count stays small. The scoped gateway endpoint always includes shared Pipeworx meta-tools; there is no documented option to remove them from that connection. Use the local package when the agent should expose only the three Hagstofa tools, or use the full Pipeworx gateway when direct access to all catalog packs is preferred.
