Hermes MCP Update: Install AI Tools from a Reviewed Catalog in One Command

Hermes has shipped a significant MCP update: instead of manually digging through documentation, copying config files, and hoping nothing breaks, there is now a reviewed MCP catalog you browse like a menu and install with a single command. The update also adds granular per-tool action controls, automatic updates while Hermes runs, and the ability for Hermes itself to act as an MCP server for other agents.

Key Takeaways

A new MCP catalog ships with Hermes — a curated, reviewed list of tools you browse and install without touching config files.
Installing a tool from the catalog takes one command and one Enter keystroke; no manual JSON editing or terminal restarts.
Per-tool action whitelisting lets you control exactly which actions each MCP is allowed to take — whitelist what you want, block what you don't.
Tools auto-update while Hermes is running — no downtime or manual update steps required.
Hermes can now expose itself as an MCP server, letting other agents call Hermes as a tool in their own pipelines.

Why This Matters

Before this update, connecting an MCP tool to Hermes meant finding the right documentation, locating and editing a config file, restarting Hermes, and debugging whatever broke. For non-technical users this was a significant barrier; even experienced users found it tedious for each new tool.

The catalog approach mirrors how package managers work: everything reviewed and available from one place, installed with a standard command. The security model is also improved — instead of an all-or-nothing tool connection, you now define a whitelist of specific actions each MCP can perform, limiting blast radius if a tool behaves unexpectedly.

New Capabilities Summary

MCP catalog: Browse reviewed tools in a menu; one command installs to your Hermes instance.
Action whitelisting: Per-tool permissions — specify exactly which tool actions are allowed.
Auto-updates: Tools update in the background while Hermes continues running.
Parallel safe tools: Tools flagged as safe can run in parallel, speeding up multi-tool workflows.
Hermes as MCP server: Other agents can now call Hermes as a tool, enabling multi-agent orchestration pipelines where Hermes handles specific subtasks.
