Octopus Energy public API MCP — UK energy tariffs & products.

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

Tools

Tool	Description
`list_products`	List Octopus Energy UK energy products (electricity & gas tariff families, e.g. "Agile Octopus", "Flexible Octopus"). Returns {count, results:[{code, display_name, direction, is_variable, is_green, is_tracker, is_prepay, is_business, term, available_from, available_to}]}. The "code" feeds product_details. Optional filters narrow the list.
`product_details`	Full detail for one product code, including its tariffs broken out by GSP region "_A".."_P" and payment method (e.g. direct_debit_monthly). Each tariff entry has a "code" (e.g. "E-1R-AGILE-24-10-01-C"), standing charges and unit rates (inc/exc VAT). Use the tariff "code" with tariff_unit_rates. Tariff sets returned: single_register_electricity_tariffs, dual_register_electricity_tariffs, four_rate_ev_electricity_tariffs, single_register_gas_tariffs.
`tariff_unit_rates`	Time-series of electricity unit rates for a specific tariff — for Agile this is the half-hourly wholesale-tracked pricing. Returns {count, results:[{value_exc_vat, value_inc_vat, valid_from, valid_to, payment_method}]} in p/kWh, newest first. Set kind="standing_charges" for the p/day standing charge instead. Defaults to the most recent rates; pass period_from/period_to to bound a window.
`grid_supply_point`	Map a UK postcode to its GSP (Grid Supply Point) group "_A".."_P". The group_id is the region suffix used in tariff codes and in product_details regional breakdowns. Returns {count, results:[{group_id}]}.

Quick Start

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

config.json

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/octopus-energy/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:

config.json

{
  "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:

Code

ask_pipeworx({ question: "your question about Octopus Energy data" })

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