Kaseya BMS MCP Server

Model Context Protocol (MCP) server for the Kaseya BMS PSA API. Exposes tickets, accounts, contacts, contracts, time entries, the service catalog, and the knowledge base to AI assistants.

Tools

Tool	Description
`kaseya_bms_list_tickets`	List tickets. Optional `$filter`; status pick if omitted.
`kaseya_bms_get_ticket`	Get a ticket by id.
`kaseya_bms_create_ticket`	Create a new ticket (destructive — confirmation required).
`kaseya_bms_add_ticket_note`	Append a note to a ticket (destructive — confirmation required).
`kaseya_bms_list_time_entries`	Time entries by date range (24h / 7d / 30d / custom / all).
`kaseya_bms_list_accounts`	Accounts (clients).
`kaseya_bms_list_contacts`	Contacts.
`kaseya_bms_list_contracts`	Contracts.
`kaseya_bms_list_service_catalog`	Service catalog items.
`kaseya_bms_search_knowledge_base`	Knowledge base search.

When the user omits required filters or runs a destructive action, the server uses MCP elicitation to prompt for choices or confirm.

Configuration

Environment-variable mode (default)

Variable	Required	Description
`KASEYA_BMS_TENANT_SUBDOMAIN`	yes	Tenant subdomain (e.g. `yourcompany`)
`KASEYA_BMS_API_TOKEN`	one of	BMS API token (secret)
`KASEYA_BMS_K1_TOKEN`	one of	Kaseya One SSO token (secret)
`MCP_TRANSPORT`	no	`stdio` (default) or `http`
`MCP_HTTP_PORT`	no	HTTP listen port (default `8080`)
`AUTH_MODE`	no	`env` (default) or `gateway`

Either KASEYA_BMS_API_TOKEN OR KASEYA_BMS_K1_TOKEN is required.

Gateway mode

When deployed behind the WYRE MCP Gateway, set AUTH_MODE=gateway and the server will read credentials from per-request HTTP headers:

X-Kaseya-BMS-Tenant-Subdomain (required)
X-Kaseya-BMS-API-Token (or)
X-Kaseya-BMS-K1-Token

Each request creates a fresh server instance with isolated credentials — no cross-tenant process.env pollution.

Local development

npm install
npm run build
KASEYA_BMS_TENANT_SUBDOMAIN=yourcompany \
  KASEYA_BMS_API_TOKEN=... \
  npm start

Run as HTTP for testing:

MCP_TRANSPORT=http npm start
curl http://localhost:8080/health
