Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

check_model_dependencies

Is my stack okay? Check a list of model ids against the record: scheduled retirements with days-remaining countdowns and migration targets, past retirements, and other breaking/action-required changes. Id matching tolerates dots vs dashes, dated snapshot suffixes, and bare or provider-prefixed forms. Call this at startup or in CI with the models you depend on.

modelsarray, required

Model ids to check, e.g. ["gpt-4o", "claude-sonnet-4-6", "gemini-2.5-flash"].

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

get_model

Unified card for one model in a single call: normalized pricing, capabilities (context window, vision, reasoning, tags), availability, reseller markup vs. upstream, and a price-history summary (launch vs. current price, percent change, last change date, all-time low/high).

list_events

The changelog of record for the model layer: deprecations, price changes, launches, and the market events around them.

provider	string	Filter to events touching this provider.
severity	string	Filter by what the event demands of consumers of the affected models.
