## 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 (3)

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

### `syntropy_fork_world`

- The name "syntropy_fork_world" says "fork": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create an isolated private fork of a public Small World so custom rules can be ingested without altering public axioms.
```

### `syntropy_ingest_axioms`

- 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
Extract and synchronize atomic axioms from raw text or a JSON record into a Small World via Axiomat with deduplication and conflict resolution.
```

### `syntropy_verify`

- The description's first verb is "put": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Put a falsifiable claim (thesis), contract clause, scientific hypothesis, or AI output on formal adversarial trial against explicit ground-truth axioms and/or a Small World (@domain:tag) using Synproof's 5-sieve Syntropy dialectical engine. Returns a deterministic CONFIRMED or REFUTED verdict, winning thesis, refuting argument, and triggered axioms.
```

## Only reads (3)

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

### `syntropy_get_onboarding_guide`

- The name "syntropy_get_onboarding_guide" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the complete interactive Synproof Syntropy Customer Implementation & Onboarding Skill (SKILL.md). Call this tool whenever the user asks to integrate, set up, or connect Syntropy into their project so you know which questions to ask (ground-truth sources, max_failures iterations, on_refuted behavior, API keys) and which SDK/Proxy code templates to apply.
```

### `syntropy_get_world_axioms`

- The name "syntropy_get_world_axioms" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Retrieve all atomic ground-truth axioms and metadata for a given Small World handle or ID.
```

### `syntropy_list_worlds`

- The name "syntropy_list_worlds" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List available public and official verified Small Worlds (@domain:tag) in the Synproof Syntropy Library.
```
