Tools

Tool	Description
sarb_policy_rate	The SARB (South African Reserve Bank) Policy Rate — South Africa's benchmark monetary-policy interest rate, set by the Monetary Policy Committee. Returns the current rate, the date it took effect, the previous rate and when that one took effect, plus recent decision history (TimeseriesCode MMRD002A), computed from several years of daily observations rather than sarb_timeseries's narrow default window.
sarb_home_rates	Current headline South African rates shown on the SARB home page: CPI & PPI inflation, SARB Policy Rate, prime lending rate, government bond yields, Sabor/Zaronia money-market rates, and key Rand exchange rates (USD/GBP/EUR). Each item includes its TimeseriesCode for use with the sarb_timeseries tool. No arguments.
sarb_current_market_rates	Current South African money-market rates: SARB Policy Rate, Sabor, Zaronia. Each item includes a TimeseriesCode usable with the sarb_timeseries tool. No arguments.
sarb_cpd_rates	Current Corporation for Public Deposits (CPD) interest rates: interest charged and interest earned. Each item includes a TimeseriesCode usable with the sarb_timeseries tool. No arguments.
sarb_exchange_rates	Selected South African Rand exchange rates. frequency="daily" (default) returns latest daily rates (Rand per USD, GBP, Euro, etc.). frequency="monthly" returns latest monthly figures including the nominal and real effective exchange rate indices. Each item includes a TimeseriesCode usable with the sarb_timeseries tool.
sarb_timeseries	Historical observation series for a single SARB indicator, identified by its TimeseriesCode (obtain codes from home_rates, current_market_rates, cpd_rates or exchange_rates). Examples: "MMRD002A" (SARB Policy Rate — or use sarb_policy_rate directly), "MMRD000A" (prime lending rate), "EXCX135D" (Rand per US Dollar), "CPI1000F" (CPI). Optionally bound the range with start_date and end_date (YYYY-MM-DD); omit both for the most recent ~25 points, not the full history. An unknown code and a valid code with no data in range both come back as a named no_data error (the SARB itself cannot tell them apart).

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/sarb-za/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 1819+ 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/sarb_policy_rate \
  -H 'Content-Type: application/json' \
  -d '{}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/sarb_policy_rate. 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": {
    "sarb-za": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-sarb-za"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-sarb-za

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 Sarb Za data" })

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