The agentic rag, wrung out.
Tools & PluginsFriday, October 23, 2026
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.
Directly useful for anyone running paid MCP tools (Meshy, image gen, external APIs). Prevents runaway spend without forcing constant manual oversight.

Teknium shared progress on the official Meshy plugin for Hermes Agent. It ships as both MCP and Skill, with deep Hermes Desktop integration: models render inline in chat, credits appear on the status bar, and a gallery of all generated models is available. File-type selection for downloads was also added in-chat. Official Meshy docs confirm text/image/multi-view to 3D, texturing, remeshing, rigging, and print prep via the Meshy CLI (no API key required after browser sign-in).

Teknium released an official Hermes plugin that bundles the REA MCP plus a skill for effective use. REA lets the agent reverse-engineer apps (Electron, native binaries, .NET, Android, firmware) and return decompiled code, call graphs, and evidence. One command installs both the MCP and the skill. Native decompilation still requires the user’s own Ghidra/Hopper/IDA.
