Iso Codes

@pipeworx/iso-codes

ISO codes MCP — country (ISO 3166-1, -2, -3), language (ISO 639-1/-2/-3), currency (ISO 4217), and script (ISO 15924) lookups. Data fetched from the debian iso-codes project (raw JSON on github). Keyless; cached 24h in-pack.

Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.

Tools

• country(query) — lookup country by name / alpha-2 / alpha-3 / numeric
• subdivisions(country_alpha2) — ISO 3166-2 subdivisions of a country
• language(query) — lookup language by name / 2-letter / 3-letter code
• currency(query) — lookup currency by name / code / numeric
• script(query) — lookup script (ISO 15924)
• list(kind, filter?) — list all of one kind: countries | languages | currencies | scripts

Data source

raw.githubusercontent.com/{ISO 3166-1, ISO 639-3, ISO 4217, ISO 15924} JSON in salsa.debian.org/iso-codes-team/iso-codes.

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/iso-codes/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 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

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 Iso Codes data" })

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