Spend Limits and Price Tags for Paid Tools

Paid MCP tools (3D generation, media, etc.) can declare per-call cost. Approval prompts show the call price plus the conversation total. Hermes still asks before exceeding a chat-level limit, even in YOLO mode. Cron/unattended runs simply refuse over-limit calls. Configurable in config.yaml or via plugin packages.

Why it matters

Direct answer to runaway cost risk as the plugin ecosystem expands. Gives operators a hard control surface without disabling YOLO for routine work.

Approval Model Contrast (User Returns to Hermes)

User reported OpenBot ignored a “cannot be reversed” warning and user rule files after they had already declined the setting. After 30 minutes of testing they switched back to Hermes. Teknium welcomed them.

MCP Spend Limits Land in Hermes 0.22.4/0.22.5

MCP servers can now declare tool costs. Set a per-chat spend cap; calls that would exceed it prompt for approval even on trust-full mode. Approval UI shows the cost. Part of the broader plugin and cost-control wave.
