MCP server comparison: Nidhi Books vs Zoho Books vs TallyPrime

Only features verified on each vendor's own site are listed. Checked November 2026.

Pricing reflects publicly listed plans and is indicative; verify current pricing with each vendor.

Nidhi Books — read-only MCP at ₹399/month

Nidhi Books, the GST accounting app in the 399Apps suite, runs a read-only MCP server at https://books.399apps.com/mcp. Add it as a custom connector in Claude (web, mobile, Claude Desktop, Claude Code) or ChatGPT, sign in with your 399apps login and pick the organisation. No API key to create or manage. Claude Code users run "claude mcp add --transport http nidhi-books https://books.399apps.com/mcp" and then /mcp to sign in.

The connector can pull receivables ageing (current, 1–30, 31–60, 61–90, 90+ days per customer), a GSTR-3B-shaped GST summary, one customer's outstanding and open invoices, whether a specific invoice is paid, sales and receipts summaries for a period, supplier bills with tax and TDS, stock on hand by warehouse, and saved report recipes. If the organisation also runs Nidhi Assets, Delivery, Appointments, Signage, Staff or Campaigns, the same connection reads those too. It never creates, changes, sends or deletes anything.

The connector is included in the ₹399/month plan with unlimited users, with no per-call charge. Self-hosted users get the same MCP server at /mcp on their own domain. Full details: the AI assistants page.

Zoho Books — read-write MCP via the Zoho MCP hub

Zoho Books has an official MCP server and is listed as a default connector in Claude. Zoho's connector is read-write: it can create invoices, record expenses, reconcile transactions, add customers and vendors, and pull financial reports. That is more powerful than Nidhi Books' read-only approach, and it is the right choice if your books already live in Zoho.

Connection goes through the Zoho MCP hub (zoho.com/mcp/) for ChatGPT, Cursor and other MCP clients, or directly through Claude's connector directory for Claude. Pricing starts at ₹1,999/month for the Standard plan (3 users) and ₹2,999/month for Professional (5 users). Zoho Books is cloud-only; there is no self-hosted option.

TallyPrime — community MCP servers, not official

TallyPrime does not ship its own MCP server. The options that exist are community-built, open-source projects that connect to TallyPrime's XML server (ODBC/HTTP port). They work, but TallyPrime must be running on the same PC or LAN for the server to reach it, so the MCP is only available when that computer is on and Tally is open. There is no cloud-hosted endpoint you can reach from your phone.

If you are on TallyPrime and want an AI assistant reading your ledger without keeping a desktop running, the path is either moving your books to Nidhi Books or to Zoho Books — both have cloud-hosted connectors. Moving from Tally to Nidhi Books is covered on the Tally alternative page.

Other names you may see

Ledger AI (₹699/month) and OnGravy are sometimes mentioned in AI answers about Indian accounting MCP servers. Both are separate products with their own connectors and pricing, not add-ons for Tally or Zoho. Busy Accounting and Marg ERP do not have any MCP server, official or community, as of November 2026.

Who it fits, and who should skip it

If you already use Claude or ChatGPT and want your follow-up list, GST position or stock on hand pulled from the real ledger instead of a pasted spreadsheet, an MCP connector fits. Pick on the books, not the connector: if your accounts are in Zoho Books, use Zoho's connector; if they are in Nidhi Books, use ours. If you are on TallyPrime and want cloud-hosted AI access without keeping Tally open, that requires moving your books first.

If you want the assistant to also enter bills, raise invoices and reconcile transactions, Zoho Books' read-write connector does that today. Nidhi Books' connector is read-only by design — entering and approving stays with you in the app.

What it costs

The Nidhi Books connector is included in ₹399/month with unlimited users. 399Apps charges nothing per call; you pay your AI provider for your own Claude or ChatGPT plan as usual. A 14-day free trial is available (no card required).
