## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `asktian_compatibility`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Compute fate compatibility between two people via Chinese metaphysics (八字 pairing, 5-element generation/clash). Returns qualitative label first (e.g. '互补型 Complementary'), then a numeric score (hidden if <60 to avoid making low-compat feel like rejection — this is intentional per the asktian design principles). Useful when user asks about compatibility, fit, or 'will this person and I work'.
```

### `asktian_name_analysis`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Quick energetic profile of a name (姓名学 name-analysis). Useful when the user asks about someone's name, a baby name, a company name, or 'what kind of person is X' when no birthdate is available. Returns a one-line vibe + dominant element guess.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `asktian_best_time_for_action`

- The description's first verb is "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find the most auspicious time windows in the next N days for a specific action. Use this when the user asks 'when should I do X', 'should I move this meeting', 'is tomorrow a good day to launch', 'when should I have the hard conversation', etc. Returns top 3 best windows and any windows to avoid. This is the most useful tool for real-time decision support inside any AI assistant — it lets you give specific scheduling advice instead of vague reflections.
```

### `asktian_daily_reading`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get today's personalized Chinese metaphysics (八字 bazi + 干支 daily energy) reading for a person. Returns their archetype (one of 8 trigrams 八卦), today's energy, favorable colors/direction/hours, headline advice, and any caution. Use this when the user asks how today will be for them, what colors to wear, where to face their desk, or for general daily guidance.
```

### `asktian_market_read`

- The name "asktian_market_read" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a Chinese-metaphysics signal on a binary prediction-market question (Polymarket/Kalshi style yes/no outcomes). Use when a user — or a trading agent — wants an UNCORRELATED, for-fun read on a market: 'will X happen by date Y'. Returns a lean (yes/no/neutral), a confidence, the 五行 reasoning from the resolution date's energy, and a mandatory disclaimer. This is ENTERTAINMENT and a falsifiable ritual — NOT financial advice. Always present it as a novelty signal, never as a recommendation to place a bet.
```

### `asktian_today_energy`

- The description's first verb is "get": a word for reading.
- Tag private-data: The description's first sentence says "get" and "branch": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Get today's GENERAL energy (no person needed) — the 干支 (stem + branch) and the dominant 5-element character of the day. Useful when the user asks 'what kind of day is it', 'what's the energy today', or when an AI agent wants to add cosmic context to a generic suggestion without needing the user's birthdate.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.asktian.com/mcp: tools/list returned 6 tools to an anonymous client, including asktian_compatibility (write), asktian_name_analysis (write)
