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 Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability65
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 548 tokens (~137/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 Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.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 current MCP spec version (2026-07-28).Pass
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.
- 4 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 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 →
compute_natal_chart Compute Natal Chart ~170
Compute a full natal (birth) chart: 10 planets (sign/degree/house/retrograde), 12 Placidus house cusps, and inter-planetary aspects (major aspects, classic orbs). Pass lng/lat/tz_str (e.g. -74.01, 40.71, 'America/New_York') for exact offline computation; otherwise city+nation are geocoded online.

validate_interpretation Validate Interpretation ~241
Anti-hallucination confirmation gate (kosma-style): verify interpretation claims are grounded in the chart before publishing them. chart_json = exact JSON from compute_natal_chart or get_current_transits. claims = JSON array: [{"text": "...", "factors": [ {"type": "aspect", "a": "Sun", "b": "Moon"}, # aspect exists in chart {"type": "planet_house", "a": "Sun", "b": 5}, # planet is in that house {"type": "planet_sign", "a": "Sun", "b": "Leo"}, # planet is in that sign {"type": "house_sign", "a": 5, "b": "Leo"}]}] # house cusp is in that sign A claim is supported only if >= 2 of its factors independently exist in the chart. Returns per-claim verdicts; gate = "blocked" if any claim is unsupported — rewrite the claim against verified factors or drop it.
