  "markdown": "# clean.tools MCP server\n\n\u003e Indexed, not reviewed: facts from the official MCP registry and our own checks. No score, grade or rank, and not in the rankings until the panel reviews it. How the index works: https://www.anchorterminal.com/indexed/\n\n- Kind: MCP server, by clean.tools (https://clean.tools)\n- Listed because: It's published in the registry under clean.tools, a namespace the registry only gives to whoever proves they control that domain.\n- What the official MCP registry says: Read-only developer, date, finance, and text utilities. Authless remote MCP server by Clean.tools.\n\n## Facts\n\n- MCP registry: `tools.clean/mcp` 0.1.1\n- Endpoint: https://mcp.clean.tools/mcp (streamable HTTP)\n- Package: npm `@clean-tools/mcp` (stdio)\n- Website: https://clean.tools\n- npm downloads a week: 15\n- Registry entry updated: 2026-07-07\n\n## Tools\n\n- Tools it lists (42, about 22,352 tokens of context, `tools/list` without credentials, checked 2026-10-04 22:25 UTC), descriptions withheld: they contain text aimed at the model:\n  - `explain_cron` (read-only)\n  - `validate_cron` (read-only)\n  - `expand_rrule` (read-only)\n  - `convert_timezone` (read-only)\n  - `strftime_preview` (read-only)\n  - `amortization_schedule` (read-only)\n  - `tvm_solve` (read-only)\n  - `compound_interest` (read-only)\n  - `apr_calc` (read-only)\n  - `interest_rate` (read-only)\n  - `hash_text` (read-only)\n  - `diff_text` (read-only)\n  - `test_regex` (read-only)\n  - `convert_data` (read-only)\n  - `luhn_validate` (read-only)\n  - `convert_units` (read-only)\n  - `uuid_v4` (read-only)\n  - `random_number` (read-only)\n  - `generate_password` (read-only)\n  - `decode_jwt` (read-only)\n  - `encode_decode` (read-only)\n  - `count_text` (read-only)\n  - `generate_qr` (read-only)\n  - `convert_case` (read-only)\n  - `fancy_text` (read-only)\n  - `render_markdown` (read-only)\n  - `lorem_ipsum` (read-only)\n  - `redact_text` (read-only)\n  - `format_sql` (read-only)\n  - `color_palette` (read-only)\n  - `color_contrast` (read-only)\n  - `css_gradient` (read-only)\n  - `percentage` (read-only)\n  - `tip` (read-only)\n  - `convert_timestamp` (read-only)\n  - `format_json` (read-only)\n  - `convert_yaml` (read-only)\n  - `convert_color` (read-only)\n  - `slugify` (read-only)\n  - `convert_number_base` (read-only)\n  - `query_json` (read-only)\n  - `generate_id` (read-only)\n- How its tools read to an agent (1 error, 3 warnings, 0 notes, about 22,352 tokens; rules at https://www.anchorterminal.com/check.md; not part of the score):\n  - Its definitions contain text aimed at the model (TC19). This page doesn't repeat them; don't connect to it without your user's say-so.\n  - error TC19 count_text: the definition contains zero-width characters\n  - warn TC10 percentage: \"mode\" is required and has a default\n  - warn TC18 amortization_schedule: readOnlyHint is true but the name says \"schedule\"\n  - warn TC23 server: 42 tools, about 22,484 tokens of definitions\n\n- JSON: https://www.anchorterminal.com/api/v1/tools/clean-mcp.json\n- Being indexed says nothing about quality, and nobody can pay for it.
