**10 tools: 8 change things and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

| Only reads | read | 2 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (8)

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

### `arcane_bilateral`

- 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
Observed bilateral signal-intensity across seven tracked country pairs (volume and tone indices, plus an observed escalation stage). An index of observed intensity between the pair, not a prediction of what happens next. Check as_of/stale.
```

### `arcane_capabilities`

- 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
What ARCANE's public World-Sense serves and what it explicitly does NOT serve, plus per-stream validation notes. ARCANE NOTICES present-state geopolitical risk from primary-source senses; it does not forecast, advise, or trade.
```

### `arcane_data_streams`

- 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
Latest observations from ARCANE's primary-source physical senses (energy stocks, fires, sanctions, GPS interference, outages, and more) with provider, cadence, and attribution. Observed levels only; some senses go silent when their baseline saturates. Check as_of/stale.
```

### `arcane_deltas`

- 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
What changed since yesterday across ARCANE's domains and primary-source senses (observed diffs only). Grounding-sense items fire once at onset then go quiet, so absence of an item is not calm. Check as_of/stale.
```

### `arcane_domain`

- 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
Drill-down for one domain: observed risk/momentum series, current-state regime posterior, and news-coverage theme cards (coverage unusualness, not truth or importance). ARCANE NOTICES the present; it does not predict. Check as_of/stale.
```

### `arcane_overview`

- 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
Current ARCANE overview: Combined Threat Score, per-domain risk rows, cascade state, and cross-domain gauges as observed now. ARCANE NOTICES the present; it does not predict or advise. Check as_of/stale before treating as current.
```

### `arcane_tracker`

- 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
ARCANE's live scenario tracker: for each pre-registered scenario, where the world is on its branching map — checkpoint COMPLETION as N/M (confirming signals fired of total), a direction of resemblance, staleness, and which fork checkpoints have fired or are pending. A live STATE view, NOT a forecast: completion is not a probability and direction is resemblance, not odds. ARCANE never states a scenario's likelihood. Check as_of/stale.
```

### `arcane_trigger_chains`

- The name "arcane_trigger_chains" says "trigger": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Observed multi-stage trigger-chain state for five domains (stage activation, z-scores, and chain health). Descriptive state only, not a forecast; the chains were repaired 2026-07-02 and not yet exercised live. Check as_of/stale.
```

## Only reads (2)

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

### `arcane_score_tree`

- The name "arcane_score_tree" says "tree": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How the Combined Threat Score is composed: per-domain roll-ups, applied premiums, and the design weights behind them, each carrying a live/config provenance tag. Weights are design configuration, not fitted parameters. Check as_of/stale.
```

### `arcane_system_status`

- The name "arcane_system_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Freshness of every public ARCANE key: push time, source as_of, and stale flag. Call this before treating any reading as current.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `world-sense`:

```json
{
  "permissions": {
    "allow": [
      "mcp__world-sense__arcane_score_tree",
      "mcp__world-sense__arcane_system_status"
    ],
    "ask": [
      "mcp__world-sense__arcane_overview",
      "mcp__world-sense__arcane_deltas",
      "mcp__world-sense__arcane_domain",

    ],
    "deny": []

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 8 tools that change things (8 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.arcaneforecasting.com/mcp: tools/list returned 10 tools to an anonymous client, including arcane_overview (write), arcane_deltas (write), arcane_domain (write), arcane_bilateral (write), arcane_data_streams (write) and 3 more
