Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)

mcp-ine-es

INE Spain (Instituto Nacional de Estadística) Tempus3 JSON API MCP.

Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.

Tools

ToolDescription
list_operationsList all available INE statistical operations (Spain). Each has a numeric Id, a Codigo (e.g. "IPC"=CPI, "EPA"=labor force survey), and a Nombre. Use the Codigo or Id with tables_for_operation.
tables_for_operationList the statistical tables belonging to one INE operation. operationId may be the numeric Id (e.g. 25) or the operation code (e.g. "IPC", "EPA"). Each table has an Id used by series_in_table / table_data.
series_in_tableList the data series contained in an INE table. Each series has a COD (series code, e.g. "IPC251852") and a Nombre describing the breakdown. Pass a COD to series_data.
table_dataFetch data points for ALL series in an INE table at once. Use nult=N for the last N periods, or date="YYYYMMDD:" for everything from that date on (trailing colon = open-ended range). Each series object carries a Data[] array of {Fecha (epoch ms), Anyo, Valor}.
series_dataFetch data for ONE INE series by its code. Use nult=N for the last N periods, or date="YYYYMMDD:" for from that date on. Returns the series with its Data[] array of {Fecha (epoch ms), Anyo, Valor} points.
variable_valuesList the values of an INE classification variable (e.g. provinces, age groups, ECOICOP groups). With no variableId, lists all variables; with a variableId, lists that variable's allowed values (each has an Id, Codigo, Nombre). Useful for understanding the breakdowns inside tables.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "ine-es": {
      "url": "https://gateway.pipeworx.io/ine-es/mcp"
    }
  }
}
What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/ine-es/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1683+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/list_operations \
  -H 'Content-Type: application/json' \
  -d '{"lang":"EN"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/list_operations. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "ine-es": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-ine-es"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-ine-es

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Ine Es data" })

The gateway picks the right tool and fills the arguments automatically.
