We couldn’t confirm it starts correctly

The install command started, but didn't respond the way we expected when we tried to talk to it.

npx -y @pipeworx/mcp-ssb-no

initialize succeeded but no response to tools/list.

This is an experimental automated check and can have false negatives — missing environment variables, a slow cold install, etc. It doesn’t necessarily mean something’s wrong. Last checked 8d ago.

Overview

Ssb No MCP server connects MCP clients to Statistics Norway’s PxWebApi for browsing subjects, inspecting table definitions, and querying statistical data. Its three pack-specific tools navigate the SSB table hierarchy, return dimensions and valid values, and submit PxWeb query objects. Use it when an agent needs live SSB data by numeric table ID. It is available through the Pipeworx gateway or as a standalone local stdio package.

Use cases

  • Browse SSB subject categories to find a statistical table
  • Inspect table dimensions and accepted values before querying
  • Retrieve selected data from an SSB PxWebApi table
  • Run SSB queries locally through an MCP stdio process

Key features

  • Navigate the SSB subject tree
  • Inspect table variables and valid values
  • Query PxWebApi tables with JSON bodies
  • Connect through hosted MCP or local stdio
  • Call subject discovery over HTTP

How Ssb No works

What the Ssb No MCP server does

The Ssb No MCP server exposes Statistics Norway’s PxWebApi through MCP. It focuses on finding and querying SSB statistical tables rather than providing a general-purpose database interface. Agents can browse the subject hierarchy, inspect a table’s structure, and retrieve values from a selected table.

The pack has three primary tools:

  • subjects lists the children of a node under /table/. An empty path starts at the root. Returned nodes include an ID, a type, and display text. Folder nodes use type l; table leaves use type t.
  • table_meta returns the variables, dimensions, and valid values for a numeric SSB table ID.
  • query_table sends a PxWeb query object to a numeric SSB table ID and returns the selected data.

How it works

A typical workflow starts with subjects. Follow IDs such as be or be05 to move through the subject tree until you find a table. The ID on a table leaf is the numeric identifier needed by the other tools; an example in the documentation is 07459.

Next, call table_meta to learn which dimensions the table exposes and which values are accepted. Use that information to construct the body for query_table. Dimensions can be selected explicitly. If dimensions are omitted, PxWeb elimination rules may collapse them instead of returning every possible combination.

The hosted endpoint is available at https://gateway.pipeworx.io/ssb-no/mcp. Through that connection, the pack’s tools appear alongside shared Pipeworx meta-tools. ask_pipeworx can route a natural-language question across the wider Pipeworx catalog, while the standalone package exposes only the Ssb No tools.

Setup and configuration

For a hosted connection, add the MCP URL to a compatible client’s server configuration. No environment variables are documented for either deployment method.

The local package runs through npm with npx -y @pipeworx/mcp-ssb-no. Configure it as a stdio MCP server by setting the command to npx and passing -y and @pipeworx/mcp-ssb-no as arguments. This local mode does not require a Pipeworx account or a gateway round trip.

Without an MCP client, hosted tools can also be called over HTTP. For example, POST https://gateway.pipeworx.io/v1/tools/ssb_no_subjects with a JSON body containing {"path":""} starts a subject-tree lookup.

Tools and capabilities

The Ssb No MCP server supports subject discovery, table-schema inspection, and data retrieval from SSB PxWebApi tables. The gateway endpoint also includes Pipeworx-wide discovery and routing tools, but those are not part of the standalone package.

Limitations and notes

The pack-specific tools require a numeric SSB table ID for metadata and data queries. A caller must use the table structure and valid values returned by table_meta to build a suitable PxWeb request. The Ssb No MCP server does not document write operations or tools outside the three SSB functions.

The hosted pack endpoint and the full Pipeworx gateway reach the same broader source catalog, but they differ in which tools are listed directly. The hosted pack endpoint includes shared meta-tools; the local package does not. The gateway’s exact tool scope can change, so its initialize response is authoritative.

Frequently Asked Questions about Ssb No

Ssb No is an MCP server that connects AI clients to Statistics Norway’s PxWebApi. Its main tools browse the SSB subject tree, inspect table metadata and valid dimension values, and query statistical tables with PxWeb request objects. It can run locally over stdio or through the hosted Pipeworx MCP gateway.

Install it as a local stdio server with `npx -y @pipeworx/mcp-ssb-no`. Add `npx` as the command and pass `-y` and `@pipeworx/mcp-ssb-no` as arguments in your MCP client configuration. This mode does not require a Pipeworx account.

Connect by adding `https://gateway.pipeworx.io/ssb-no/mcp` as the server URL in the client’s MCP configuration. The README specifically shows Claude Desktop, Cursor, and Windsurf as supported setup targets.

First use `subjects` to locate a table, then call `table_meta` with its numeric ID to inspect dimensions and valid values. Pass the chosen selections in a PxWeb query object to `query_table`. Omitted dimensions may be collapsed through PxWeb elimination behavior.
