How to Set Up and Use India Stack
MCP India Stack is a zero-authentication, offline-first MCP server that exposes 58 tools covering the core Indian financial and compliance data stack: GSTIN lookup and GST rate calculations, IFSC code resolution, PAN and Aadhaar structural validation, UPI provider lookup, pincode-to-district mapping, HSN/SAC code search, income tax calculations for both old and new regimes, EMI and SIP calculators, EPF/ESIC contributions, and bulk validation operations. It is designed specifically for AI agents building Indian fintech, compliance, and business automation workflows, with no external API keys required for most features because it uses offline datasets that refresh automatically in the background.
Prerequisites
- Python 3.10 or later
- pip for installing the package
- An MCP-compatible client such as Claude Desktop
- No external API keys required for most tools — the server uses locally cached datasets
Install the package
Install mcp-india-stack from PyPI using pip.
pip install mcp-india-stackOptionally disable automatic background updates
By default the server refreshes its offline datasets in the background. Set this environment variable if you want to control updates manually.
export MCP_INDIA_STACK_NO_AUTO_UPDATE=1
# To manually refresh all datasets:
mcp-india-stack --refresh-allAdd the server to your Claude Desktop configuration
Edit your claude_desktop_config.json to register the server. The config file location differs by OS.
Restart Claude Desktop
Restart the application to load the new MCP server. You should see all 58 tools available in the tool list.
Test with a GSTIN lookup
Ask Claude to validate a GSTIN number. The server performs structural and checksum validation offline — no network call is made for basic validation.

Use natural language to query Indian financial data, validate identifiers, and run tax calculations.
- "Validate GSTIN 27AAPFU0939F1ZV and tell me the state and business type."
- "What is the IFSC code for SBI branch in Connaught Place, Delhi?"
- "Calculate my income tax for a salary of ₹18,00,000 under the new tax regime for FY2025-26."
- "What HSN code applies to mobile phones and what is the GST rate?"
- "Calculate EMI for a home loan of ₹50 lakhs at 8.5% for 20 years."
- "Validate these 3 PAN numbers in bulk and flag any with invalid format."Troubleshooting India Stack
Server not found after pip install
Ensure the Python executable in your MCP config matches the Python where you installed the package. If you used a virtual environment, reference its python3 binary explicitly: e.g., "/path/to/venv/bin/python3" instead of "python3".
GSTIN or PAN validation returns 'invalid' for a seemingly correct identifier
The validators check structure and checksum only — they do not verify active government registration. A structurally correct GSTIN that has been cancelled will still pass validation. Use the result as a format check, not as proof of active registration.
Tax calculations differ from what a CA quoted
The tax engine covers standard individual slab rates and common deductions, but excludes edge cases such as NRI status, special income categories, and state-specific surcharges. Always confirm with a chartered accountant for filing decisions.
