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 Security83
- 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 is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1046 tokens (~209/item across 5 items; 4 tools + 1 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 Coverage93
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 80% of tool parameters carry a description.Partial
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 6 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
- Supports UI / widget rendering.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 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

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 →
compare_charts Human Design connection between two people ~127
Compares two people's charts: every channel the pair forms, grouped as electromagnetic (each brings one gate), companionship (both have it), dominance (one has it, the other neither gate) and compromise (one has it, the other one gate), with who holds what; the type, definition and defined centres of the combined chart; and each person's Type, Authority and Profile.
| Name | Type | Req | Description |
|---|---|---|---|
| language | string | – | Language of the titles and summaries: en (default), nl (Dutch) or de (German). |
| person_a | object | yes | – |
| person_b | object | yes | – |
No output schema declared.
No examples provided.
explain Explain a Human Design term ~185
Explains one Human Design element in plain words: a type ("Projector"), an authority ("emotional authority"), a profile ("4/6"), a line ("line 3"), a definition ("split definition"), a centre ("Sacral"), a channel ("34-20"), a gate ("gate 51") or a basic topic ("what is Human Design", "open centres"). Gives the title and summary, the full text for types, authorities, profiles, definitions and basics, and the related centres, channels and gates.
| Name | Type | Req | Description |
|---|---|---|---|
| language | string | – | Language of the titles and summaries: en (default), nl (Dutch) or de (German). |
| topic | string | yes | The element or topic, e.g. "Manifesting Generator", "splenic authority", "2/4", "gate 34", "channel 10-20", "Ajna centre". |
No output schema declared.
No examples provided.
get_chart Human Design chart from birth data ~381
Computes a person's Human Design chart from date, time and place of birth: Type with Strategy, Signature and Not-Self theme, Authority, Profile, Definition, Incarnation Cross angle and gates, defined and open centres, defined channels, and all 26 Personality and Design activations (planet, gate, line). Each element comes with its title and a one-line summary. When the birth time is unknown or approximate, it lists which parts of the chart could change within that window. Positions come from an ephemeris calculation (true lunar node, Design moment at 88 degrees of solar arc before birth), with historical time zones.
| Name | Type | Req | Description |
|---|---|---|---|
| birth_date | string | yes | the person's date of birth as YYYY-MM-DD, e.g. "1988-03-21". |
| birth_place | string | – | Where the person's was born, as "City", "City, Country" or "City, Region, Country", e.g. "Utrecht, Netherlands", "Springfield, Illinois, USA". Used only to find the time zone. |
| birth_time | string | – | the person's local clock time of birth, 24-hour HH:MM, e.g. "14:05". Leave out when unknown: noon is used and time_uncertainty_minutes defaults to 720. |
| language | string | – | Language of the titles and summaries: en (default), nl (Dutch) or de (German). |
| time_uncertainty_minutes | integer | – | How far off the birth time may be, in minutes either way (e.g. 30 for "around half past two"). The result then says which parts of the chart could change. |
| timezone | string | – | IANA time zone of the birthplace, e.g. "Europe/Berlin". Needed only when the place is not found; overrides the place's zone when given. |

get_transits Human Design transits for a date ~161
The gates and lines the Sun, Moon, nodes and planets activate at a moment (now by default, or a given date and time in UTC). With a person's birth data it also lists the channels the transits complete with that person's own gates, the usual way to read a day's influence, apart from channels the transits form on their own.
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | – | Day to look at as YYYY-MM-DD (default today). |
| language | string | – | Language of the titles and summaries: en (default), nl (Dutch) or de (German). |
| person | object | – | – |
| time_utc | string | – | Time of day in UTC as HH:MM (default now when date is today, else 12:00). |

How do I install the Tessera Human Design MCP server?
Tessera Human Design is a hosted endpoint at https://bigballi.com/Tessera/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.
