Claude connector and batch workflow improvements

Released: 25 August 2026

This release prepares the production connector for submission to Anthropic’s Connectors Directory and improves the safety and reliability of batch accounting workflows in both Claude and ChatGPT.

Improved tool names and metadata

All 159 production tools now include clear, human-readable titles.

These titles are published both in the standard MCP tool metadata and in the annotation format used by Anthropic. This allows Claude’s Connectors Directory to display and classify RED’s tools correctly.

Existing read-only, write, destructive and open-world safety classifications remain unchanged.

Analysed cash-receipt fix

RED now preserves cash-receipt analysis entries when VAT on Cash Receipts is disabled for a company.

Previously, a valid analysis line could be removed before the request reached Big Red Cloud, causing the transaction to be rejected because the total had not been analyzed.

The corrected workflow:

• Preserves structured analysis entries

• Builds an analysis entry from supplied analysis fields

• Removes only VAT-specific fields when VAT on Cash Receipts is disabled

• Keeps VAT entries conditional on the company’s VAT settings

• Reconciles analysed receipt values to the transaction total

The shared fix also applies to supported cash-receipt update and batch workflows.

Nested batch sales documents

Batch sales invoices and sales credit notes now preserve complete nested product and analysis lines.

RED no longer replaces supplied product, VAT, analysis or note values with blank identifiers, zero values or generic placeholders when a valid nested document is provided.

The corrected payload handling preserves:

• Product IDs and codes

• Quantities and unit prices

• VAT rates and percentages

• Sales analysis categories

• Transaction notes

• Net, VAT and gross totals

Accurate batch results

RED now correctly reads Big Red Cloud’s batch-response envelope.

Batch responses clearly report:

• Whether the complete batch succeeded

• Whether only part of the batch succeeded

• Successful and failed item counts

• Details of failed items

• Created records

This prevents successful transactions from being incorrectly reported as failures and reduces the risk of users retrying transactions that were already created.

Typed batch-purchase schema

The batch-purchase tool now publishes a complete, strongly typed input contract.

Claude and ChatGPT can identify the required supplier, transaction date, purchase-analysis, net amount and VAT fields directly from the tool schema. RED continues to calculate and reconcile the final purchase totals.

Strongly typed public batch tools

The remaining public batch tools no longer expose unspecified, free-form item objects.

Strict schemas are now available for batch workflows involving:

• Quotes

• Sales invoices

• Sales credit notes

• Sales entries

• Purchases

• Cash receipts

• Cash payments

• Bank payments

• Products

• Customers

• Suppliers

• Sales representatives

The schemas identify required fields, supported accounting modes and incompatible field combinations before a request reaches Big Red Cloud.

Depending on the workflow, RED validates:

• Customer, supplier, product, bank, VAT and analysis identifiers

• Required transaction dates

• Positive amounts and identifiers

• Reconciled net, VAT and gross totals

• Correct credit-note signs

• Customer and supplier code limits

• Receipt and payment modes

• Unexpected or unsupported fields

Compatibility information

Public batch requests now use the canonical structure:

{ "opCode": 1, "item": { ... } }

Users with an existing custom RED connector should refresh or reconnect it so Claude or ChatGPT receives the latest tool metadata.

Individual non-batch accounting tools are unaffected.

Testing and verification

Version 1.6.2 was validated through:

• TypeScript type checking

• Batch payload and schema regression tests

• Transaction, routing and confirmation tests

• Registration checks across all 159 production tools

• Staging deployment and smoke testing

• Production connection and fixture verification

• Anthropic’s live production tool scan

The production catalogue contains 159 tools with no duplicate names.

What do users need to do?

Existing custom-connector users should refresh or reconnect RED to receive the latest tool schemas and titles.
