### `method_create_activity`

- The name "method_create_activity" says "create": 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: logs an activity (call, email, to-do, note) on a customer/lead. entity_id is the Customer RecordID; contact_id is the Contact RecordID (not the Customer's; method_list_contacts finds it). The text goes in Comments. Prefer activity_type_id (read it from an existing activity of that type) over the caption activity_type: a caption that matches zero or several options is silently dropped. Method requires an assignee on standard accounts. The reply re-reads the activity so you can check the links were stored (field names are account-specific; method_get_table_fields with table Activity shows them). It does not email anyone. Not idempotent. POST /api/v1/tables/Activity.
```

### `method_create_customer`

- The name "method_create_customer" says "create": 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: creates a record in Method's Customer table. is_lead true = a Customer Lead (does not sync to the accounting system); is_lead false = a full customer, which Method syncs to QuickBooks/Xero (it appears there too). Method also creates the primary Contact; its RecordID is returned as contact_id when it could be found (use it, not the customer id, to link activities). Name is required (for a person with no company use "First Last"). `extra_fields` sets other fields by their exact names (see method_get_table_fields, table Customer). Not idempotent: calling twice creates two records, so search first (method_search_customers). POST /api/v1/tables/Customer.
```

### `method_create_record`

- The name "method_create_record" says "create": 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: creates a record in any table that allows it (method_list_tables shows canCreate), e.g. Estimate, Invoice, Item, Vendor. For customers/leads and activities use the dedicated tools. Field names are case-sensitive and a wrong one is silently ignored: read them with method_get_table_fields first, and send dropdown links as their `_RecordID` integer. Creating accounting records (Invoice, Estimate, Customer ...) makes Method sync them to QuickBooks/Xero. Child lines (InvoiceLine ...) are not supported here. Not idempotent. Returns the new RecordID. POST /api/v1/tables/{table}.
```

### `method_update_record`

- The name "method_update_record" 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 fields on one record (PATCH: only the fields you pass change). Field names are case-sensitive and Method silently ignores wrong or read-only names, so the reply re-reads the record and shows the stored values of the fields you sent: check them. Linked fields are changed through their `_RecordID` integer field. Updating accounting records (Customer, Invoice ...) makes Method sync the change to QuickBooks/Xero; setting IsLeadStatusOnly to false converts a lead into a synced customer. There is no delete tool. PATCH /api/v1/tables/{table}/{recordId}.
```

## Only reads (12)

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

### `method_count_records`

- The name "method_count_records" says "count": a word for reading.
- Tag private-data: The description's first sentence says "table": it reads databases. The input names a table (input.table), and the tool reads: it reads databases.

- The name "method_get_account" says "get": 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
Who the API key acts as: the Method user behind it (id and name; use the id as an assignee). Also a cheap check that the key works. GET /api/v1/me.

### `method_get_file_url`

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

```untrusted-server-text
One record by RecordID from any table. Pass `select` to limit the columns; `expand` names a related CHILD table whose rows are embedded (e.g. InvoiceLine on Invoice; at most 50 rows); a parent such as a contact's Entity is not expanded: read it with its own RecordID (Entity_RecordID).
