# roman_numerals Convert between Roman numerals and Arabic numbers. Agent View of the PolicyLayer registry record for `roman_numerals`. HTML page: https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/roman-numerals ## Facts - Tool: `roman_numerals` - Server: GadgetHumans API Hub (`pypi:gadgethumans-api-hub-mcp`) — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub.md - Install: `npx -y pypi:gadgethumans-api-hub-mcp` - Homepage: https://github.com/scotia1973-bot/api-hub - Risk category: Read (Low risk) - Registry record: grade F, 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": "roman_numerals", "arguments": {} } } ``` ## Why roman_numerals is rated Low This is a simple conversion utility that reads input (Roman numerals or Arabic numbers) and returns transformed output (the other format). It has no capability to modify data, execute code, access external systems, or cause any irreversible changes. The blast radius of misuse is minimal—worst case, an agent generates incorrect conversions, which is harmless. From the tool's own definition: "Tool description states 'Convert between Roman numerals and Arabic numbers' — a pure data transformation utility with no side effects, no external state modification, and no code execution." ## Use case AI agents call roman_numerals to retrieve information from GadgetHumans API Hub 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 GadgetHumans API Hub: ```json { "version": "1", "default": "deny", "tools": { "roman_numerals": {} } } ``` ## Other tools on GadgetHumans API Hub (310) - `clean_whitespace` — Destructive — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/clean-whitespace.md - `gravitational_force_calc` — Destructive — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/gravitational-force-calc.md - `atbash_cipher` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/atbash-cipher.md - `caesar_cipher` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/caesar-cipher.md - `crawl_website` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/crawl-website.md - `electrical_calc` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/electrical-calc.md - `evaluate_math` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/evaluate-math.md - `filter_data` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/filter-data.md - `fn` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/fn.md - `generate_password` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/generate-password.md - `hash_text` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/hash-text.md - `http_client` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/http-client.md - `ini_to_json` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/ini-to-json.md - `matrix_operations` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/matrix-operations.md - `momentum_calc` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/momentum-calc.md - `pressure_calc` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/pressure-calc.md - `ratio_calc` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/ratio-calc.md - `test_regex` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/test-regex.md - `web_scrape` — Execute — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/web-scrape.md - `agent_memory` — Other — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/agent-memory.md - `generate_ulids` — Other — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/generate-ulids.md - `alternating_case` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/alternating-case.md - `amortization_calc` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/amortization-calc.md - `anagram_check` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/anagram-check.md - `analyze_tone` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/analyze-tone.md - `analyze_url` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/analyze-url.md - `angle_convert` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/angle-convert.md - `area_convert` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/area-convert.md - `ascii_table` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/ascii-table.md - `auto_loan_calc` — Read — https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/auto-loan-calc.md - …and 280 more: https://policylayer.com/tools/io-github-scotia1973-bot-api-hub.md ## For agents This record is a snapshot.
