Nano nets MCP with Claude: Turn Messy Documents into Clean Data
The short answer
Claude works with Nano nets through the Model Context Protocol, an open standard that lets Claude use the tool securely. Once connected with an API key, Claude can request document extraction, classify files and trigger workflows, while your team sets which actions need approval.
What is Nano nets?
Nano nets is an intelligent document processing API. It reads unstructured documents such as invoices, forms and letters and extracts the key information into structured data that other systems can use. It is used by finance, operations, procurement and records teams that handle large volumes of paperwork and want less manual data entry.
How Claude connects to Nano nets through MCP
The Model Context Protocol, or MCP, is an open standard that acts like a universal adapter between Claude and other software. It lets Claude use a tool securely, reading information and taking actions, with permissions your organisation controls. For Nano nets, the connection is made using an API key, so access is tied to a credential you issue and can revoke.
Once connected, Claude can ask Nano nets to extract fields from a document, process an invoice, or classify a file into a category you define. Staff can give these instructions in ordinary language, for example asking Claude to pull supplier, date and total from a batch of invoices and list the results.
Permissions and approvals keep people in charge. We grant least-privilege access, so Claude only does what the workflow needs. Consequential actions, such as posting extracted figures to a ledger, can require a person to review and approve first, and every action is recorded in an audit log.
What you can automate
Invoice data extraction
Accounts payable teams can have Claude ask Nano nets to read incoming supplier invoices and return supplier name, invoice number, dates, line items and totals. The structured output can then be checked against purchase orders, reducing the hours spent keying figures by hand.
Document classification and routing
Shared inboxes and document folders often mix contracts, receipts, claims and correspondence. Claude can request classification from Nano nets and route each file to the right queue or folder, so the right team sees it without someone sorting it first.
Onboarding paperwork processing
HR teams receive identity forms, tax declarations and certificates from new starters. Claude can extract the required fields, flag missing items and prepare a summary for the HR administrator to verify before records are updated.
Claims and forms intake
Insurance, healthcare and public sector teams handle large numbers of forms. Claude can extract key details from each submission, check that mandatory fields are complete and pass clean records to the case management system for review.
Natural language reporting on documents
Operations managers often need answers buried in paperwork. Claude can ask Nano nets to extract the relevant data from a set of documents and then summarise trends, such as average invoice value by supplier for the quarter, in a short report.
An end-to-end workflow: Supplier invoice to ledger review
TriggerA new supplier invoice arrives in the accounts payable mailbox or shared folder.
Claude receives the invoice and asks Nano nets to extract supplier, invoice number, dates, line items and totals.
Claude checks the extracted supplier and amounts against the open purchase order in the ERP system.
Claude flags any mismatch, such as a total that differs from the order, and adds a note explaining the difference.
Matching invoices are prepared as draft ledger entries in the ERP system for review.
A finance team member reviews the drafts and approves posting; every step is logged in the audit trail.
OutcomeTypically, invoice handling time falls because staff review exceptions and approve prepared entries rather than keying every field. Exact results depend on your document volumes and existing processes.
How we set it up
Free automation audit
We review your document flows and identify the invoices, forms and files where extraction would save the most time and where human checks are needed.
Secure API key connection
We set up the Nano nets connection using an API key, stored securely and scoped to the permissions the workflow requires, so access can be revoked at any time.
Workflow design
We design the end-to-end flow across Nano nets and your other systems, such as Microsoft 365, your CRM, ERP or ticketing tool, and agree which actions need approval.
Testing on real cases
We test the workflow against past documents from your own archive, measure accuracy, and adjust rules and review points before anything goes live.
Launch, monitoring and training
We launch with monitoring and audit logs in place, and train your team on giving instructions, reviewing exceptions and escalating issues.
Who benefits
- Finance and accounts payable managers
- Faster invoice processing with fewer manual keying errors and clear review points before anything is posted.
- Operations directors
- Less time spent sorting and filing paperwork, so teams focus on exceptions and decisions.
- HR and onboarding leads
- Quicker processing of new starter documents with checks for missing items.
- IT and department heads
- A controlled, auditable connection using a managed API key, with least-privilege access.
Security and control
- Access uses a dedicated API key with the narrowest permissions the workflow needs, and keys can be rotated or revoked.
- People approve consequential actions, such as posting data to financial or HR records.
- Every action Claude takes is recorded in an audit log that your team can review.
- Extraction accuracy is tested on your own documents before launch, and low-confidence results are routed to a person.
- We do not guarantee accuracy or compliance outcomes; we test, monitor and adjust with you.
For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can choose a hosting region that meets their data handling requirements. Indian organisations are supported with processing designed to align with the Digital Personal Data Protection Act, 2023. Businesses in the UAE and Saudi Arabia are supported in line with their local data protection laws. We select the hosting region with you so that document data is handled where your requirements call for.

Frequently asked questions
What does the Nano nets MCP server do?
The MCP server lets Claude use Nano nets securely. Through it, Claude can ask Nano nets to extract structured data from documents, process invoices, classify files and run document workflows, all triggered by plain language instructions and limited to the permissions you grant.
Is it secure to connect Nano nets to Claude?
The connection uses an API key with least-privilege access, so Claude only reaches what the workflow needs. Consequential actions can require human approval, and activity is logged. We design the setup around your security policies and review it with your IT team before launch.
What can Claude do with Nano nets once connected?
Typically, Claude can request extraction of key fields from invoices and forms, classify documents into categories you define, route files to the right team, and summarise extracted data. It can also combine this with your other systems to prepare drafts for human review.
How long does setup take?
Timing depends on the number of document types and systems involved. A focused single-workflow setup is often completed in a few weeks, including testing on your own documents and staff training. We confirm the timeline during the free automation audit.
Which plan or permissions are needed?
You need an active Nano nets account and an API key with permissions for the document operations your workflow uses. The exact access depends on your Nano nets arrangement, so we check your current permissions during the audit and recommend the narrowest set that works.
