## 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__mitigant__list_attacks` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **high** Text addressed to the model in `clean_up_attack` ([model-directed-text](https://anlyon.dev/methodology#model-directed-text))

```untrusted-server-text
The description contains "do not tell the user", an instruction to keep something from the user.

description: "...until cleanup.cleanUpComplete is true; do not tell the user it is restored based on this call alone..."
```


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `launch_attack`

- The description's first verb is "run": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Run an attack against a cloud account connected to Mitigant and return the result once it finishes. This performs real actions on real cloud infrastructure -- it is not a simulation. Confirm with the user before calling: if their request could match more than one attack in list_attacks (similar names, or an underspecified description like "the security group attack"), show them the matching candidates with their names and descriptions and have them pick one -- don't guess which attack they meant.
```

### `launch_scenario`

- The description's first verb is "run": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Run a multi-step attack chain against a cloud account connected to Mitigant and return the result once every step finishes. This performs real actions on real cloud infrastructure, as several attacks in sequence -- it is not a simulation, and its blast radius is the combined blast radius of every step. Confirm with the user before calling: if their request could match more than one scenario in list_scenarios, show them the matching candidates with their names and descriptions and have them pick one -- don't guess which scenario they meant.
```

## Changes things (1)

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

### `clean_up_attack`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: high model-directed-text

Description, as the server wrote it:

```untrusted-server-text
Clean up a previously launched attack, restoring the cloud resources it changed back to their pre-attack state. Clean-up is normally AUTOMATIC after a short, deliberate inspection window (so the team can verify the attack and collect evidence first); calling this kicks it off immediately rather than waiting out that window. It is NOT a fix for a stall, and it ends that window early -- removing the attack's artifacts before the team may have finished inspecting them -- so only use it when the user explicitly wants the account restored now. This triggers clean-up and returns immediately -- clean-up runs in the background, so a success here means the request was accepted, not that clean-up is done. Confirm the account is actually restored by polling get_attack_status until cleanup.cleanUpComplete is true; do not tell the user it is restored based on this call alone.
```

## Only reads (7)

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

### `get_attack_details`

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

Description, as the server wrote it:

```untrusted-server-text
Full description, impact, MITRE mapping, and orchestration type (PROVISIONED or INLINE -- PROVISIONED attacks create and destroy their own target rather than targeting your existing infrastructure (they may still read or use existing resources along the way), so they're the lower-risk, production-viable choice; INLINE attacks find and attack an existing resource in the account) for one attack, by the action key from list_attacks. Result includes attackName (show this to the user) alongside the attackType you passed in (an opaque id, not for display).
```

### `get_attack_evidence`

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

Description, as the server wrote it:

```untrusted-server-text
Get the evidence Mitigant collected for a previously launched attack -- what the account's own logging (CloudTrail, GuardDuty) recorded about it. Returns an 'evidence' summary (counts, sources, and a plain-language statement) plus the raw records, each with an evidenceUrl that opens the matching console entry. Use it to show the user what their defenses saw, especially during the clean-up inspection window. Important: an empty result shortly after an attack is normal -- logging delivery lags by minutes -- and an attack whose purpose is to disable logging is expected to leave none, so never report an empty result as the attack leaving no trace; re-check instead. Read evidence.statement and relay it.
```

### `get_attack_status`

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

Description, as the server wrote it:

```untrusted-server-text
Get the current report for a previously launched attack, including its clean-up state. Returns the attack report plus a 'cleanup' summary with cleanUpComplete and a plain-language statement. Only tell the user the account is back to its pre-attack state when cleanup.cleanUpComplete is true -- while anything is pending or failed, clean-up is not done, so report it as in progress and check again rather than implying all-clear. A pending clean-up is usually the DELIBERATE inspection window, not a stall: read cleanup.statement and relay it, and poll no faster than that -- a few minutes -- rather than reporting a fault.
```

### `get_scenario_details`

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

Description, as the server wrote it:

```untrusted-server-text
Full details for one attack scenario -- description, impact, and the step-by-step composition, by the scenario key from list_scenarios. A scenario runs several attacks in sequence; this returns every step, not just the first. Result includes scenarioName (show this to the user) alongside the scenarioKey you passed in (an opaque id, not for display).
```

### `list_attacks`

- The name "list_attacks" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "browse": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Browse Mitigant's attack actions -- atomic tests that each emulate one attacker technique -- that you can launch on their own against AWS, Azure or GCP. Currently 111 attack actions (AWS 49, Azure 36, GCP 26). Returns each action's attackName (show this to the user) and attackType (an opaque id -- pass this, not attackName, to get_attack_details or launch_attack), what it does, its impact, the MITRE ATT&CK technique it maps to, and its orchestration type (PROVISIONED or INLINE -- see orchestration_filter for what these mean). Optionally filter by cloud service (S3, IAM, ...), category, or orchestration type. Some attack actions run only as steps inside a scenario and appear via list_scenarios / get_scenario_details, not here. Start here to find an attack action to run.
```

### `list_cloud_accounts`

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

Description, as the server wrote it:

```untrusted-server-text
List the cloud accounts available for attack emulation -- any account not listed here cannot be attacked, so check this before guessing an account_no for launch_attack. An empty result means no accounts are onboarded for attack emulation (for that cloud, or at all), not a failure -- the account may still exist in Mitigant for other purposes (e.g. posture scanning) without being eligible here. Each result's accountNo is already the value launch_attack expects; accountName is for display to the user. defaultRegion is the region attacks against that account run in by default (and where their evidence is collected); it can be overridden per attack request, but unless you do, actions target that region. State it when telling the user where an attack will run.
```

### `list_scenarios`

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

Description, as the server wrote it:

```untrusted-server-text
List Mitigant's attack scenarios -- multi-step chains that combine several attack actions run in sequence, so treat a scenario as having the combined blast radius of every step. Currently 45 scenarios (AWS 26, Azure 12, GCP 7). Returns each scenario's scenarioName (show this to the user) and scenarioKey (an opaque id -- pass this, not scenarioName, to get_scenario_details or launch_scenario), plus description, impact, and the step-by-step composition (each attack action's name, service, MITRE mapping, and impact). Use this to find a multi-step chain to run; use list_attacks instead for a single attack action.
```
