MCP-India-Stack
Provides an MCP server with tools for Indian government/finance-related lookups (e.g., IFSC, pincode, HSN/SAC, GST state codes), format/checksum validators (e.g., GSTIN, PAN, UPI VPA, Aadhaar checksum, etc.), and offline tax/fee calculators for FY2025-26. It supports offline-first operation with bundled datasets and an optional background/manual dataset refresh from a CDN.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
The README describes "Zero auth"; this is a major security consideration for any network-exposed deployment. No explicit TLS/auth/configuration guidance is provided in the supplied content. Dependency hygiene can’t be fully assessed from the manifest alone, but the dependency list is small and standard. Secret handling guidance isn’t documented; likely no secrets are required due to zero-auth and offline dataset usage.
⚡ Reliability
Best When
You need fast, offline-capable validation/enrichment and estimation inside an AI agent using the Model Context Protocol with locally available datasets.
Avoid When
You require authenticated access control, audited real-world verification, strict legal/tax finality, or strong guarantees that all reference data is up-to-the-minute without refresh.
Use Cases
- • AI agents that need to validate or parse Indian identifiers (GSTIN, PAN, UPI VPA, etc.)
- • Agent workflows that enrich inputs with reference data (IFSC branch info, pincode postal info, HSN/SAC lookup, GST state code metadata)
- • Offline-capable document/field validation pipelines for Indian compliance data
- • Estimating GST/TDS/income-tax components for FY2025-26 within an agent workflow
Not For
- • Verifying real-world/active status with issuing authorities (explicitly described as format-only for several IDs)
- • Making final legal/tax decisions without professional advice (tax calculators are estimates)
- • Systems requiring strong authentication/authorization or user-level access control (described as zero auth)
- • Real-time accuracy-critical applications that must always reflect the latest government notifications without refresh
Interface
Authentication
The README describes the server as "Zero auth". No auth mechanisms, scopes, or access control are documented.
Pricing
No pricing information provided in the supplied data (appears to be an open-source package distributed via PyPI under MIT).
Agent Metadata
Known Gotchas
- ⚠ Zero-auth access means you should isolate the MCP server network-wise if used beyond a trusted environment.
- ⚠ Validators are format/checksum only for multiple IDs; do not assume authoritative verification.
- ⚠ Tax calculations are estimates for FY2025-26; outcomes may differ from actual liability/notifications.
- ⚠ Reference datasets may be stale until background/manual refresh completes; agent should consider refresh timing for accuracy-critical flows.
