A signed-in Claude Code is now offered as a provider (claude/…) like Codex
and Copilot. Anthropic classifies another agent's system prompt as
third-party traffic even over Claude Code's OAuth, so magpie drives the
real local claude binary for every generation: the caller's tools are
bridged in over MCP (magpie claude-mcp-helper), and tool results resume
the same Claude Code turn. Token counting is estimated locally so the
OAuth token takes no side path.
No model list is compiled in any more. The built-in catalog, preset
defaults and Claude Code's alias list are gone; the picker shows the
models.dev catalog (refreshed in the background when stale) layered with
each vendor's own /models answer, and signed-in accounts fetch theirs at
start-up. Whether a model rejects temperature/top_p now comes from
models.dev rather than a name prefix.
The gateway retries a Chat request on the Responses endpoint when the
model is Responses-only, and remembers that. Recent calls keep the first
256 KB of request and response bodies, viewable in the call list. The
Usage tab shows subscription allowances (Claude, Codex, Copilot) as the
vendors report them.
