HTML page: https://policylayer.com/tools/rehan1020-mcp-india-stack/validate-cin ## Facts - Tool: `validate_cin` - Server: Mcp India Stack (`rehan1020/mcp-india-stack`) — https://policylayer.com/tools/rehan1020-mcp-india-stack.md - Homepage: https://github.com/rehan1020/MCP-India-Stack - Risk category: Read (Low risk) - Registry record: grade C, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "validate_cin", "arguments": {} } } ``` ## Why validate_cin is rated Low CIN validation checks the format and validity of a Corporate Identification Number against government registry data. This is a read-only query operation with no side effects, no data modification, and no execution of arbitrary code. The server description confirms it provides 'master data lookups' for identity and government information. From the tool's own definition: "Tool name 'validate_cin' and sibling tools like 'bulk_validate_aadhaar', 'bulk_validate_gstin', 'bulk_validate_pan', 'bulk_validate_ifsc' all perform validation/lookup operations." ## Use case AI agents call validate_cin to retrieve information from Mcp India Stack without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp India Stack: ```json { "version": "1", "default": "deny", "tools": { "validate_cin": {} } } ``` ## Other tools on Mcp India Stack (59) - `build_aa_consent_request` — Other — https://policylayer.com/tools/rehan1020-mcp-india-stack/build-aa-consent-request.md - `calculate_advance_tax` — Other — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-advance-tax.md - `calculate_emi` — Other — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-emi.md - `calculate_gratuity` — Other — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-gratuity.md - `calculate_income_tax` — Other — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-income-tax.md - `calculate_income_tax_interest` — Other — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-income-tax-interest.md - `calculate_salary_restructuring` — Other — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-salary-restructuring.md - `calculate_tds` — Other — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-tds.md - `bulk_validate_aadhaar` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/bulk-validate-aadhaar.md - `bulk_validate_gstin` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/bulk-validate-gstin.md - `bulk_validate_ifsc` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/bulk-validate-ifsc.md - `bulk_validate_pan` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/bulk-validate-pan.md - `calculate_capital_gains` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-capital-gains.md - `calculate_epf_esic` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-epf-esic.md - `calculate_fd_maturity` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-fd-maturity.md - `calculate_gst` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-gst.md - `calculate_gst_late_fee` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-gst-late-fee.md - `calculate_home_vs_rent` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-home-vs-rent.md - `calculate_hra_exemption` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-hra-exemption.md - `calculate_leave_encashment_tax` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-leave-encashment-tax.md - `calculate_neft_rtgs_imps_charges` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-neft-rtgs-imps-charges.md - `calculate_nps_projection` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-nps-projection.md - `calculate_ppf_maturity` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-ppf-maturity.md - `calculate_presumptive_tax` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-presumptive-tax.md - `calculate_professional_tax` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-professional-tax.md - `calculate_rd_maturity` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-rd-maturity.md - `calculate_sip_returns` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-sip-returns.md - `calculate_step_up_sip` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-step-up-sip.md - `calculate_sukanya_samriddhi` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-sukanya-samriddhi.md - `calculate_surcharge` — Read — https://policylayer.com/tools/rehan1020-mcp-india-stack/calculate-surcharge.md - …and 29 more: https://policylayer.com/tools/rehan1020-mcp-india-stack.md ## For agents This record is a snapshot.
