HourProof — volunteer/service hour ledger (no AI)

Official6 tools

by hourproof

Deterministic check of logged service hours: bad dates, impossible totals, duplicates. No AI.

app.rowb.hourproof/hours — MCP Server Model Context Protocol

The MCP server app.rowb.hourproof/hours performs a deterministic validation of logged service hours. Its description specifies checks for bad dates, impossible totals, and duplicates, with an explicit “No AI” constraint. The output is intended to ensure consistency in time/hours records rather than generate or infer data.

🛠️ Key Features

Deterministic validation of logged service hours
Detects bad dates
Detects impossible totals
Detects duplicate entries
No AI

🚀 Use Cases

Verifying that service hour logs include valid dates
Ensuring totals are mathematically possible
Preventing repeated hour entries in records

⚡ Developer Benefits

Predictable, rules-based checks (deterministic behavior)
Clear validation scope: dates, totals, duplicates

⚠️ Limitations

Limited to logged service-hours validation as described
No AI-based analysis or inference

Captured live from the server via tools/list.

check_hours

Check a list of logged service/volunteer hours for internal consistency: bad dates, non-positive or impossible day totals, missing organization, and days above this service's 8-hour flag. Deterministic arithmetic only - no AI. It does NOT decide whether the hours satisfy any school or award requirement.

Parameters2

entries	array	required	Entries to check. Each: {date:"YYYY-MM-DD", hours:number, activity:"what was done", organization:"where", category?:"tutoring", notes?}.
as_of	string	optional	Treat this date as "today" (YYYY-MM-DD) when rejecting future dates. Defaults to the server date.

get_rules
