validate_config

dev.3tg/mcp · Verify this server

Validate a 3TG configuration object (`.3tg.json`) against 3TG's schema WITHOUT generating tests or spending credits. Use this whenever you or the user has hand-edited `.3tg/config.3tg.json` (or a per-source `.3tg/<source>.md.3tg.json`) — it catches the mistakes that would otherwise surface as confusing failures at generation time. WHAT IT CATCHES (via 3TG's `-C` check-config pass): - a value of the wrong type (e.g. `mock-parameters` set to a string instead of an object); - an unknown / misspelled key, including invalid rule names (e.g. `rules.string.no-emppty` or a `no-such-rule`); - any other Draft-7 schema violation. This complements the `3tg://schema/config` resource: read that resource to discover the valid keys; call this tool to actively verify a concrete config before saving it. This tool is FREE — no clientId, no quota. On failure, `problems` lists the exact schema-violation lines 3TG reported; surface them to the user and help fix the config, then re-validate. A `valid: true` result means the config is structurally accepted by 3TG (it does not assert the values are semantically ideal for any particular source file).
