Xero

Exposes Xero's accounting data (invoices, bills, contacts, accounts, transactions) through the Model Context Protocol, enabling Claude and other MCP-compatible clients to query and manipulate live business data without custom API wrappers. Uses OAuth 2.0 authentication to Xero's REST API and translates MCP tool calls into authenticated HTTP requests, maintaining session state and handling rate limiting transparently.

Manages access to multiple Xero organizations (tenants) within a single MCP session, allowing Claude to switch between different business entities and maintain separate accounting contexts. Implements tenant selection through MCP tool parameters and maintains isolated authentication tokens per organization, enabling multi-company accounting workflows without session switching.

Translates Claude's natural language accounting questions into structured Xero API queries by mapping semantic intent to specific API endpoints, filters, and parameters. Uses MCP tool definitions to expose accounting operations (list invoices, get contact details, retrieve transactions) as callable functions, allowing Claude to decompose complex accounting questions into sequences of API calls without explicit SQL or API syntax knowledge.

Provides MCP tools to create, update, and track invoices and bills through their complete lifecycle (draft, submitted, paid, overdue). Implements state transitions through Xero API endpoints, validating required fields (line items, tax codes, payment terms) and handling status-dependent operations (e.g., marking invoices as sent, recording payments). Supports batch operations for bulk invoice/bill creation and status updates.

Provides MCP tools to create, update, and query contact records (customers, vendors, employees) with associated metadata (addresses, phone numbers, tax IDs, payment terms). Implements contact deduplication logic and maintains relationships between contacts and transactions. Supports bulk contact imports and updates through MCP tool parameters, with validation of required fields and format constraints.

Provides MCP tools to generate financial reports (P&L, balance sheet, cash flow, trial balance) and export accounting data in multiple formats (JSON, CSV). Implements report filtering by date range, account code, and tracking categories, with support for comparative reporting (period-over-period, year-over-year). Reports are generated on-demand by querying Xero's reporting API and transforming results into structured formats suitable for analysis or external consumption.

Provides MCP tools to retrieve unreconciled bank transactions and suggest matching accounting entries based on amount, date, and description similarity. Implements fuzzy matching logic to correlate bank transactions with invoices, bills, and manual journal entries, reducing manual reconciliation effort. Supports bulk reconciliation confirmation through MCP tool parameters, updating transaction status in Xero's bank reconciliation module.

Provides MCP tools to retrieve tax-related accounting data (tax codes, tax rates, GST/VAT transactions) and generate tax compliance reports required for filing. Implements country-specific tax configuration retrieval and supports filtering transactions by tax code or rate. Generates summary reports suitable for tax return preparation, with support for multiple tax jurisdictions and reporting periods.
