Agentic Keychain
Registry that benchmarks reusable agent skills and sells some; its MCP tools evaluate and quote.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢evaluate_capability(task, capability, model, expected_runs, baseline_cost_estimate_usd, ...)
Decide whether a registry capability is worth buying for your task, from registry-run benchmarks only. Returns decision, expected effect, price, confidence, reasons, operator_message, next steps and an ak.offer.v1 offer (status, next_action, economics, the four evidence kinds listed apart). Give model, expected_runs and baseline_cost_estimate_usd for a money estimate.

}🟢estimate_roi(capability, model, expected_runs, baseline_cost_estimate_usd)

}🟢get_capability(capability)
The capability's card: purpose, use-when and do-not-use-when conditions, permissions, price, evidence summary, trust checks, links and a task-independent ak.offer.v1 offer.
Input Schema
{
"type": "object",

}🟢get_quote(capability, evaluation_id)
A signed 15-minute price quote with the hosted checkout link. It charges nothing; a purchase requires operator approval in the hosted checkout.
