## Findings

- **info** The word "credentials" in `civicrm_query` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...mount',op:'>=',value:1000}]. Read-only; credential fields and system entities (settings, p..."
```


## Deletes or cancels (1)

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

### `civicrm_update_contact`

- The name "civicrm_update_contact" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- 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
WRITE: changes basic fields of ONE existing contact (name, job title, source, preferred language) and/or its communication preferences (do not e-mail, do not phone, do not mail, do not SMS, opted out of bulk mail). Only the fields you give are changed. Setting a do-not flag to false re-enables contact the person may have declined, so only do that on the person's request. APIv4 Contact.update.
```

## Changes things (7)

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

### `civicrm_add_contact_note`

- The name "civicrm_add_contact_note" says "add": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

- 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
WRITE: adds ONE contact to ONE static group. If the group is used as a mailing list, the contact will receive future mailings sent to it, so only add people who agreed. Sends nothing by itself. Adding a contact who is already in the group changes nothing; a contact who was removed from it (or is pending) is set back to Added. APIv4 GroupContact.save matched on group and contact.
```

### `civicrm_create_contact`

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

Description, as the server wrote it:

```untrusted-server-text
WRITE: records ONE activity (a meeting, phone call, e-mail, follow-up, ...) with one or more contacts. It only STORES the record: an activity of type Email does not send an e-mail. Added by the contact this API key belongs to unless source_contact_id is given. APIv4 Activity.create.
```

### `civicrm_record_contribution`

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