Description
Deterministic cleanup tools for decimals, whitespace, filenames, delimiters, and booleans.
What our measurements say
Internet Janitor is a remote MCP server published at internet-janitor.capneura.workers.dev. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 357 ms, placing it among the faster endpoints. It offers a narrow, focused set of 6 tools. On the protocol side it speaks the 2026-07-28 stateless spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names clearly indicate their purpose (e.g., 'normalize-whitespace', 'safe-filename')
- Diagnose-data acts as a helpful triage tool for complex formatting issues
- Consistent parameter naming with clear required fields
Weaknesses
- All tools use identical 'input' parameter without optional configuration options
- No explicit error handling or constraint documentation in tool descriptions
- Some tool descriptions focus more on implementation than usage scenarios
detect-delimiter— Could benefit from specifying maximum input size or format constraintsnormalize-decimal— Lacks explicit error handling for non-numeric inputs
Verdict
Event narrative
Risk: low
Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 38ms → warm 37ms (penalty 1ms)
Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
diagnose-dataSomething isn't working? Show me the problematic data. I will identify likely formatting problems and point to the deterministic Janitor tool that can fix them.
inputstringrequired
normalize-whitespaceCollapse repeated whitespace to one space and trim leading/trailing whitespace.
inputstringrequired
safe-filenameConvert a string into a Windows-safe filename, including reserved device-name protection.
inputstringrequired
normalize-decimalNormalize common US/EU decimal representations to a dot-decimal string. Ambiguous single separators followed by three digits are flagged.
inputstringrequired
detect-delimiterDetect comma, semicolon, tab, or pipe delimiters across up to 20 non-empty rows while ignoring delimiters inside double quotes.
inputstringrequired
normalize-booleanNormalize common boolean representations such as yes/no, on/off, 1/0, true/false.
