## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The description's first verb is "run": a word for a change.
```

- **warn** Mentions of other tools or servers in `import_monitors` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The input schema at properties.payload.description names a tool "export" that this server does not list.

inputSchema.properties.payload.description: "Export payload, version 1.0. Use the `export` tool to generate one."
```


## Deletes or cancels (1)

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

### `remove_monitor`

- The name "remove_monitor" says "remove": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Stop monitoring a domain. Accepts the domain name or the host_id returned by list_monitors.
```

## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `finalize_certificate`

- The name "finalize_certificate" says "finalize": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Finalize and issue a certificate order in one call: validates the DNS challenges, waits for Let's Encrypt, and returns the issued cert. Step 3 of issuance - call after check_certificate_propagation reports all_found.
STRONGLY PREFER passing csr_pem (generate the key + CSR locally with openssl so the private key never leaves the machine). Returns leaf_pem/chain_pem/fullchain_pem. If you must, pass a passphrase instead to get a PKCS#12 bundle - but a CSR is safer.
If it replies "still validating", DNS hasn't fully propagated: re-check check_certificate_propagation and call again.
Needs a locally-generated CSR (csr_pem) - requires a local shell with openssl. On a surface without one (e.g. a Claude.ai custom connector) this can't complete; it returns guidance to finish in Claude Code/Cowork or the web form. Scanning and monitoring work everywhere.
On success the structuredContent carries a `handoff` object - relay `handoff.message` to the user and do NOT separately call add_monitor; the cert→monitoring handoff is automatic and server-side.

```

### `invite_team_member`

- The name "invite_team_member" says "invite": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Invite a user to a team by email. Defaults to the user's current team. Honors the plan's seat limit (returns the same upgrade payload as add_monitor when the cap is hit).
```

## Changes things (8)

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

### `add_monitor`

- The name "add_monitor" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add a domain to ongoing certificate monitoring with expiry alerts. Requires authentication (the user runs /mcp once).
If the plan's monitor limit is reached, the response's structuredContent carries a limit-reached payload - when relaying it, LEAD with `recommended_upgrade` (typically Starter, $9.99/mo), mention `also_available` tiers in a single closing line, and offer removing an existing monitor as the free alternative. Don't dump a full tier comparison; that's choice paralysis at the moment of action.

```

### `add_monitors`

- The name "add_monitors" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add multiple domains to monitoring in one call. Returns a per-domain status so the caller can show partial-success outcomes. Honors the same plan-limit checks as add_monitor.
```

### `check_certificate_propagation`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Check whether the DNS TXT records for a certificate order have propagated (Cloudflare/Google/Quad9). Step 2 of issuance - poll until all_found is true, then call finalize_certificate. Returns per-record resolver results.
```

### `create_certificate`

- The name "create_certificate" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start issuing a FREE Let's Encrypt certificate for a domain (no account required). Step 1 of 3. Lifetime is Let's Encrypt's default: 90 days today, 64 days from 2027-02-10; read the real expiry from the issued certificate.
Pick a validation method with `challenge`: "dns-01" (default; publish a TXT record; covers apex + www) or "http-01" (serve a file over HTTP on port 80; issues the exact domain only). dns-01 with a DNS-provider API token is the most automatable; http-01 suits a server you control on port 80.
Returns an order_id plus either dns_records (dns-01) or http_files (http-01) to put in place. Next: poll `check_certificate_propagation` until all_found, then call `finalize_certificate`.
Strongly prefer the CSR path at finalize (the private key never leaves the user's machine). Issuing automatically offers the user ongoing monitoring by email once it completes - don't add a monitor manually afterward.

```

### `export_monitors`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Dump the user's monitors as a JSON structure suitable for backup, migration, or infrastructure-as-code workflows. Tokens and PII are NEVER included - only domain configuration.
```

### `import_monitors`

- The name "import_monitors" says "import": a word for a change.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Create monitors from a JSON structure (typically produced by `export`). Skips domains the user is already monitoring; honors the plan's domain limit. Returns a per-domain status.
```

### `renew_certificate`

- 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
Renew a certificate by cloning a recent order (requires the original order_id; Beacon purges orders after ~24h). Returns a new order_id and fresh DNS TXT records - then poll check_certificate_propagation and call finalize_certificate. If you don't have an order_id (the usual case at renewal time), call create_certificate for the domain instead; that IS the renewal.
```

### `scan_domain`

- The description's first verb is "run": 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
Run a free, anonymous SSL/TLS scan against a hostname and return certificate details. No account required.
```

## Only reads (5)

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

### `get_account`

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

Description, as the server wrote it:

```untrusted-server-text
Return the current user's plan, limits, and usage so the client can render upgrade nudges proactively.
```

### `get_certificate_status`

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

Description, as the server wrote it:

```untrusted-server-text
Return the current state of a certificate order (dns_pending, validating, ready, completed, failed) and per-authorization Let's Encrypt statuses. Use it to resume an interrupted issuance.
```

### `get_scan_history`

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

Description, as the server wrote it:

```untrusted-server-text
Return recent scan results for a domain the user monitors. Useful for spotting issuer changes, grade drops, or vulnerability appearances over time.
```

### `list_expiring_certificates`

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

Description, as the server wrote it:

```untrusted-server-text
Return monitored certificates expiring within N days. Defaults to 30.
If the response's structuredContent includes a `nudge` object, the user is watching enough soon-to-expire certs to benefit from a higher tier - mention it casually ONCE (lead with `nudge.recommended_upgrade`); skip it if it doesn't fit.

```

### `list_monitors`

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

Description, as the server wrote it:

```untrusted-server-text
List all certificates currently being monitored across the user's teams.
If the response's structuredContent includes a `nudge` object, the user is at their monitor cap - surface it casually ONCE (lead with `nudge.recommended_upgrade`, mention `nudge.also_available` in one closing line); don't force it if it doesn't fit the conversation.

```
