# retirement_calc A read tool on the GadgetHumans API Hub MCP server. Agent View of the PolicyLayer registry record for `retirement_calc`. HTML page: https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/retirement-calc ## Facts - Tool: `retirement_calc` - 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": "retirement_calc", "arguments": {} } } ``` ## Why retirement_calc is rated Low Based on the tool name and server context (utility APIs), this appears to be a computational/calculation tool that reads input parameters and returns calculated results without modifying data or executing external operations. No evidence of destructive, financial, execute, or write capabilities. From the tool's own definition: "Tool name 'retirement_calc' suggests a calculator function (read-only computation). Description is empty, limiting direct evidence. Server context lists 'amortization_calc' as a sibling, which is similarly a utility calculator." ## Use case AI agents call retirement_calc 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": { "retirement_calc": {} } } ``` ## 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.
