## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 93/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 80% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).
  - Supports UI / widget rendering.

### 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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 75, +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.

### 2026-11-03 (score 74, 0)

## MCP tools (4)

### `get_chart` (~381 tokens)

Human Design chart from birth data

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.

Input parameters:

- `birth_date` (string, required): 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` (~161 tokens)

Human Design transits for a date

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.

Input parameters:

- `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).

### `compare_charts` (~127 tokens)

Human Design connection between two people

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.

Input parameters:

- `language` (string): Language of the titles and summaries: en (default), nl (Dutch) or de (German).
- `person_a` (object, required)
- `person_b` (object, required)

### `explain` (~185 tokens)

Explain a Human Design term

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.

Input parameters:

- `language` (string): Language of the titles and summaries: en (default), nl (Dutch) or de (German).
- `topic` (string, required): The element or topic, e.g. "Manifesting Generator", "splenic authority", "2/4", "gate 34", "channel 10-20", "Ajna centre".

Tessera Human Design scores 75 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Tessera Human Design MCP server expose?

Tessera Human Design exposes 4 tools: get_chart, get_transits, compare_charts, explain. Their descriptions and schemas cost roughly 854 tokens of context every time the server is loaded.

### Does the Tessera Human Design MCP server require authentication?

No. We connected to Tessera Human Design without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Tessera Human Design MCP server still maintained?
