## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__fet112__fet112_analytics_catalog` `mcp__fet112__fet112_analytics_query` `mcp__fet112__fet112_network_state_attestation` `mcp__fet112__fet112_network_state_keys` `mcp__fet112__fet112_network_status` `mcp__fet112__fet112_pre_action_check` `mcp__fet112__fet112_recent_incidents` `mcp__fet112__fet112_security_report` `mcp__fet112__fet112_staking_context` `mcp__fet112__fet112_transaction_activity` `mcp__fet112__fet112_transaction_comparison` `mcp__fet112__fet112_verify_attestation` `mcp__fet112__fet112_verify_network_state_attestation` `mcp__fet112__fet112_verify_quantitative_context` |

## Findings

- **warn** Annotations that disagree with the tool in `fet112.analytics_query` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "fet112.analytics_query" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "fet112.analytics_query" says "query": a word for reading.
```


## Changes things (10)

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

### `fet112.analytics_catalog`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Discover supported native metrics, exact semantics, aggregations, coverage requirements and executable query examples. No model or chain RPC calls.
```

### `fet112.analytics_query`

- The name "fet112.analytics_query" says "query": a word for reading.
- The description's first verb is "execute": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Execute a validated read-only native Fetch query: sums, extrema, weighted means, groupings, rollups and comparable UTC windows. Read analytics_catalog first. Missing coverage is an error, never zero. Top rankings cannot be combined across buckets. Amount maxima do not identify transaction hashes. Inspect integrity and consumer_policy; no native security or anomaly decision.
```

### `fet112.network_state_attestation`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Attest observed native fetchhub-4 gas, transactions and blocks for the latest available finalized hour (four 15-minute windows). Signed coverage, source cursor, issue/expiry times and explicit fresh/stale/partial/unavailable observation status. No Ethereum data, native security verdict, anomaly assessment or live chain RPC. Optional content_hash retrieves an exact retained document; archive is process-local (up to 128 documents, one hour, lost at restart).
```

### `fet112.network_state_keys`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Discover current Ed25519 public key and fingerprint. Discovery is not an independent trust anchor.
```

### `fet112.pre_action_check`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Deterministic pre-flight over the current watched Ethereum security environment. V1 commits the intended action but does not classify destination, amount, asset, business authorization or simulate the transaction.
```

### `fet112.staking_context`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Observed native Fetch staking FLOW on fetchhub-4 for today or yesterday UTC, using finalized 15-minute buckets and comparable historical periods. Returns exact afet strings, coverage and source cursor. This is NOT total staked balance, a statistical anomaly assessment, or a security verdict. Signature status is explicit in integrity.signed. Errors mean unavailable evidence, never zero flow. Defaults: today, 7 baseline days.
```

### `fet112.transaction_activity`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Native fetchhub-4 transactions included in blocks for today or yesterday UTC. Returns successful/failed/total counts, success percentage and average TPS over contiguous finalized 15-minute buckets. Empty periods with valid coverage have zero TPS and a NOT_APPLICABLE/null success percentage. Missing evidence returns an error, never zero activity. Not peak TPS, capacity, messages, or mempool attempts. Signature status is explicit in integrity.signed; no statistical anomaly or security verdict. Default: today.
```

### `fet112.verify_attestation`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Verify an arbitrary SecurityReportV1/attestation pair offline, optionally against a trusted FET112 key fingerprint.
```

### `fet112.verify_network_state_attestation`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Verify canonical signed payload, pinned identity, expiry and source age independently. No live chain canonicality check.
```

### `fet112.verify_quantitative_context`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Verify the separate native quantitative Ed25519 attestation and full consumer policy. Supply a trusted fingerprint to verify identity; does not evaluate chain canonicality, freshness or security.
```

## Only reads (4)

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

### `fet112.network_status`

- The name "fet112.network_status" says "status": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Return FET112's current machine-facing network status. The verdict is copied from SecurityReportV1 for configured Fetch/ASI contracts on Ethereum (chain_id=1). Do not apply it to native fetchhub-4 traffic.
```

### `fet112.recent_incidents`

- The description's first verb is "return": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Return bounded recent incidents associated with the current signed report context.
```

### `fet112.security_report`

- The description's first verb is "return": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Return the current signed SecurityReportV1 for configured Fetch/ASI contracts on Ethereum (chain_id=1). It does not evaluate native fetchhub-4 traffic.
```

### `fet112.transaction_comparison`

- The description's first verb is "compare": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Compare native fetchhub-4 transactions TODAY and YESTERDAY over exactly the same elapsed UTC interval, ending at today's latest authoritative finalized cutoff. Both windows come from one SQLite snapshot. Returns counts, success rates, exact count difference and percentage change; unavailable coverage returns ErrorV1. No significance test, anomaly decision, cause attribution, forecast or native-chain security assessment. Follow consumer_policy. Inspect integrity.signed and verify the quantitative attestation before claiming verification.
```
