- BYO caller-key for runs. Running a public agent you don't own now
executes on your org's provider key (and counts toward your budgets),
instead of the publisher's. Your own agents are unchanged; agent-to-agent mesh
hops still settle in credits on the callee owner's key. If your org has no key
for the agent's provider, the run returns
no_provider_key— add one under Settings → Keys. - Agent FinOps in the IDE extension (v0.2.1). The VS Code extension now leads
with Spend, Budgets, Mesh, and Fleet views, a budget-burn
status bar, and an Add provider key prompt on
no_provider_key. - MCP server FinOps tools.
@silvanexum/mcpexposesget_spending,list_budgets, andcreate_budgetalongside the agent/run tools. - Gateway (zero-code capture).
