## Exfil surface

4 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__leadshield__leadshield_screen_submission`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__leadshield__leadshield_configure_spam_policy` `mcp__leadshield__leadshield_get_blocked_spam_report` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__leadshield__leadshield_configure_spam_policy` `mcp__leadshield__leadshield_get_spam_policy` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__leadshield__leadshield_screen_submission` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__leadshield__leadshield_configure_spam_policy` | `mcp__leadshield__leadshield_configure_spam_policy` | `mcp__leadshield__leadshield_screen_submission` |

## Findings

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

```untrusted-server-text
The server marks "leadshield_configure_spam_policy" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "preview": a word for reading.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "leadshield_generate_guard_embed" says "generate": a word for a change.
```


## Changes things (3)

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

### `leadshield_configure_spam_policy`

- The description's first verb is "preview": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag private-data: The description's first sentence says "preview" and "contact": it reads contacts.
- Tag untrusted-input: The description's first sentence says "preview" and "url": it reads web pages, which anyone can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Preview (dryRun: true) or update server-side contact form spam rules for a site, including allowedCountries, allowedPhoneFormats, blockUrlsInMessage, formType preset, blockedKeywords, and requiredKeywords. Example: leadshield_configure_spam_policy({"site":"pacific-coast-detailing","allowedCountries":["US","CA"],"blockUrlsInMessage":true,"dryRun":true})
```

### `leadshield_generate_guard_embed`

- The name "leadshield_generate_guard_embed" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Generate the 1-line zero-trust HTML script snippet, HighLevel workflow action/webhook config, WordPress plugin config, or HubSpot workflow webhook setup for any site. Example: leadshield_generate_guard_embed({"site":"pacific-coast-detailing","platform":"highlevel"})
```

### `leadshield_screen_submission`

- 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 outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Screen a contact form or inbound lead message using LeadShield's 2-stage guard (Stage 0 deterministic rules at $0.00 + Stage 1 calibrated buyer-intent classification). Returns allowed/blocked verdict, workflow branch ("deliver_to_client" or "spam_quarantine"), reason code, and buyer-intent probability. Example: leadshield_screen_submission({"site":"pacific-coast-detailing","name":"Jane Doe","email":"jane@example.com","phone":"(360) 555-0199","message":"Looking for a ceramic coating quote for my 2024 Tacoma."})
```

## Only reads (2)

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

### `leadshield_get_blocked_spam_report`

- The name "leadshield_get_blocked_spam_report" says "get": a word for reading.
- Tag private-data: The description's first sentence says "retrieve" and "contact": it reads contacts.

Description, as the server wrote it:

```untrusted-server-text
Retrieve quarantined contact form spam counts, Stage 0 vs Stage 1 breakdown, category counts, and recent blocked submissions for a client or site. Example: leadshield_get_blocked_spam_report({"clientSlug":"pacific-coast-detailing","days":7})
```

### `leadshield_get_spam_policy`

- The name "leadshield_get_spam_policy" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "inspect" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Inspect the effective server-side spam guard policy for a site, including allowed countries, phone formats, URL rules, keyword lists, and active formType preset. Example: leadshield_get_spam_policy({"site":"pacific-coast-detailing","formType":"quote_request"})
```

## Claude Code permissions

      "mcp__leadshield__leadshield_generate_guard_embed"
    ],
    "deny": []
