# list_color_names Get a list of named CSS colors with hex values and RGB. Agent View of the PolicyLayer registry record for `list_color_names`. HTML page: https://policylayer.com/tools/io-github-scotia1973-bot-api-hub/list-color-names ## Facts - Tool: `list_color_names` - 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": "list_color_names", "arguments": {} } } ``` ## Why list_color_names is rated Low This is a straightforward data retrieval operation that queries a predefined list of color information. There is no capability to modify data, execute code, delete resources, or cause financial impact. The blast radius of misuse is negligible—an agent cannot harm systems or data through repeated or malicious calls to fetch color definitions. From the tool's own definition: "Tool returns a static list of CSS color names with hex and RGB values. The description uses 'Get a list', indicating data retrieval with no side effects or state modification." ## Use case AI agents call list_color_names 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": { "list_color_names": {} } } ``` ## 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.
