01 MCP Server

QuickBooks Online MCP Server

7M+ small businesses - the #1 accounting platform for SMBs worldwide.

quickbooks.intuit.com

QuickBooks Online's API relies on deeply nested entity schemas that break standard LLM parsers. This MCP abstracts the underlying relational graph into flat, actionable operations. Your agents can push structured journal arrays, execute deterministic chart of account queries, and sync vendor ledgers. We handle the XML/JSON inconsistencies and rate-limit backoffs, allowing your system to safely orchestrate bulk accounts payable patching.

Xero MCP Server

02 MCP Server

Xero MCP Server

4.2M subscribers - the beautiful cloud accounting platform loved by accountants globally.

Xero's architecture is genuinely API-first, but managing its paginated bank transaction feeds is tedious. This server exposes clean, schema-validated endpoints for high-volume reconciliation. Agents can inject arrays of structured invoice objects, mutate contact metadata, and resolve unallocated payments programmatically. This enables fully headless month-end close automation without scraping the UI.

FreshBooks MCP Server

30M+ users - the invoicing and accounting platform built for freelancers and service businesses.

FreshBooks structures its billing engine around project-based time entries rather than pure ledger accounting. This MCP aligns those specific paradigms into queryable arrays. Agents can mutate client records, orchestrate complex recurring invoice pipelines, and push time-tracking deltas directly into the billing engine. This is critical for automating agency retainer syndication and programmatically syncing profitability reporting.

04 MCP Server

Wave Accounting MCP Server

Free accounting and invoicing - the go-to platform for entrepreneurs and microbusinesses.

Wave abstracts away the ledger for its end-users, but under the hood, it's a solid GraphQL-driven double-entry system. This server provides typed access to those underlying mutations. Your agents can directly patch transaction segments, orchestrate receipt-parsing extraction loops, and inject rules for automated payment categorization—bypassing the slow web interface entirely.

Zoho Books implements a modular, enterprise-grade REST architecture. This MCP maps your agent directly onto those composable finance endpoints. You can execute granular mutations on transaction types, orchestrate multi-currency normalization pipelines, and synchronize isolated journal states. We handle the complex API pagination so your agent can implement sophisticated tax compliance logic across multiple jurisdictions programmatically.
