How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-octopus-energy). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 1 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 728 tokens (~182/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
grid_supply_point ~84
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}]}.
| Name | Type | Req | Description |
|---|---|---|---|
| postcode | string | yes | UK postcode, e.g. "SW1A 1AA" (spaces optional). |
No output schema declared.
No examples provided.
list_products ~171
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.
| Name | Type | Req | Description |
|---|---|---|---|
| available_at | string | – | ISO-8601 timestamp; only products available at that moment, e.g. "2026-06-01T00:00Z". |

product_details ~156
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 ~262
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.
| Name | Type | Req | Description |
|---|---|---|---|
| kind | string | – | Which series to fetch. Default "standard_unit_rates". |
