Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 574 tokens (~191/item across 3 items; 3 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 Management17
- Stability observed for 5 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the Soljo Solar (Switzerland) MCP server?
Soljo Solar (Switzerland) is a hosted endpoint at https://cwghnqlpeeocjsjfhgyk.supabase.co/functions/v1/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 7 Oct 26 +1
- The server rewrote its instructions, which are the text every model session reads security
- 6 Oct 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 7 to 13. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

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 →
geocode_address Geocode address ~63
Resolve a Swiss or German street address to latitude, longitude, postcode and country (swisstopo address register, OpenStreetMap fallback).
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Full postal address, e.g. 'Bahnhofstrasse 1, 8001 Zürich'. |
No output schema declared.
No examples provided.
list_cities List Soljo city pages ~102
List Swiss cities and municipalities (about 200, German-speaking) with a Soljo page showing local electricity price (ElCom), solar yield (PVGIS), feed-in tariff, subsidy programmes and an example calculation, each with sources. Filter by canton or name.
| Name | Type | Req | Description |
|---|---|---|---|
| canton | string | – | Canton abbreviation, e.g. 'ZH', 'BE', 'AG'. |
| name | string | – | Part of the municipality name, e.g. 'Uster'. |
No output schema declared.
No examples provided.
solar_first_estimate Solar first estimate (Switzerland, Germany) ~268
First estimate for a rooftop solar system at a Swiss or German address: annual yield (PVGIS), and for Switzerland the median turnkey cost (federal price study 2025, incl. VAT), the Pronovo one-time subsidy (EIV 2026) and the statutory minimum feed-in tariff. Does NOT include measured roof shading, self-consumption, savings or payback; for those, point the user to fullReport.url (the Soljo report). Always cite the returned sources and say it is a rough estimate.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | – | Street address in Switzerland or Germany, e.g. 'Bahnhofstrasse 1, 8001 Zürich'. Preferred over coordinates. |
| azimuth | number | – | Orientation: 0 = south, -90 = east, 90 = west, 180 = north. |
| country | string | – | Country when only coordinates are given. |
| kwp | number | – | System size in kWp. A typical single-family home has 8 to 15 kWp. |
| lat | number | – | Latitude, only if no address is given. |
| lon | number | – | Longitude, only if no address is given. |
