Wondering how the new Hermes Agent connectors page works and where the MCP tab went? The quick version is just below — then I’ll walk you through what actually changed in v0.21.5, how to update, and how to use the new “Connect now” flow without breaking your existing setup.
Short answer:
- Hermes Agent v0.21.5 (released 24 September 2026, per the official GitHub release) replaces the old MCP tab with a new Connectors page.
- There’s a “Connect now” flow, and freshly installed plugins now show their MCP servers and tools live in chats.
- Update with
hermes update(git installs), the installer one-liner, or thenousresearch/hermes-agent:v2026.9.24Docker image. - The same release adds GPT-6 Sol/Terra/Luna and Claude Opus 5.5 to the model catalogs, plus voice shortcuts and a Simple/Advanced interface toggle.
What the Hermes Agent connectors page actually is
Hermes Agent v0.21.5 shipped on 24 September 2026 as a stable tagged release that rolls up roughly 460 pull requests merged since v0.21.4, per the official release notes on GitHub. Buried in that list is the change most people will actually notice day to day: the MCP tab is gone, and a Connectors page has taken its place.
If you’ve been running MCP servers in Hermes for a while, this is the same plumbing with a much friendlier front door. Instead of thinking in protocol terms (“which MCP server do I wire up?”), you think in outcome terms (“connect this tool”). The new “Connect now” functionality handles the connection flow, and catalog plugins are now featured in onboarding alongside connectors — so new users see working integrations on day one instead of an empty config screen.
The other quality-of-life change: when you install a plugin, its MCP servers and tools now show up live in chats. No restart-and-pray. If you’re new to Hermes, start with my best Hermes setup guide before you start connecting things.
Hermes Agent connectors vs the old MCP tab
Here’s the practical difference, based on what the v0.21.5 release notes describe:
| Old MCP tab | New Connectors page |
|---|---|
| Managed connections under a protocol-named tab | Dedicated Connectors page with “Connect now” flow |
| Plugin tools appeared after reloads | MCP servers and tools appear live in chats on fresh plugin installs |
| Integrations discovered manually | Catalog plugins featured in onboarding alongside connectors |
| One interface for everyone | Sits alongside the new Simple/Advanced interface mode toggle on Desktop |
None of your existing connections are being deprecated here — this is a relabel and a workflow upgrade, not a protocol change. That matters if you’ve already invested in a working stack, like connecting Hermes to your password manager the way I covered in the Hermes Agent 1Password integration guide.

How to update to v0.21.5 (three ways)
Straight from the official release page, released 24 September 2026:
- Git installs: run
hermes updateand you’re done. - Installer users: re-run the installer one-liner from the docs.
- Docker/Cloud: pull
nousresearch/hermes-agent:v2026.9.24.
Because this is a patch release explicitly aimed at “downstream consumers”, it’s the tag I’d pin if you’re running Hermes in anything resembling production. If you’re running Hermes on a Claude subscription rather than API keys, my guide to using Hermes Agent with a Claude Code subscription still applies after this update.
Everything else worth knowing in v0.21.5
The Connectors page is the headline, but the release notes list a lot more. The highlights, per the official changelog:
- Model catalogs: GPT-6 Sol, GPT-6 Terra, GPT-6 Luna and Claude Opus 5.5 added.
- Interface: a Simple/Advanced mode toggle for Desktop, RTL/LTR text direction setting, and per-profile stop/start/restart controls plus a
gateway.standaloneoption. - Voice and input: function-key and dictation voice shortcuts.
- Plugin SDK: a composer draft API with session-list and row-decoration slots, sidebar navigation preferences, model-pill label providers, a sandboxed embed primitive, an appearance-settings slot, and a public event bridge for plugin backends.
- Localisation: complete French, German and Spanish Desktop catalogs.
- Integrations: an official Blender Lab integration and NVIDIA app/Broadcast plugins.
- Performance: optimisation across config loading, the tool registry, gateway messaging and the model picker.
For automation builders, the public event bridge is the sleeper feature — plugin backends can now react to events properly, which pairs nicely with structured output workflows like the ones in my Hermes Agent stream JSON output guide.
How I’d use this for SEO
Connectors are only interesting if they remove friction from something that makes money. The play I recommend: connect your research sources and your publishing stack through the Connectors page, then let Hermes handle the boring middle — briefs, drafts, internal linking suggestions — while you keep editorial control. The onboarding now surfacing catalog plugins means the setup cost for a working content pipeline has genuinely dropped with this release.
If you’re not sure which connectors are worth the time for an SEO workflow, that’s a fifteen-minute conversation on a free SEO strategy session rather than a weekend of trial and error.
The bottom line on Hermes Agent connectors
The Connectors page is the most user-facing change Hermes Agent has shipped this month: same MCP underneath, far less friction on top, and live tool availability in chats the moment a plugin lands. Update via hermes update or the v2026.9.24 image, poke at “Connect now”, and rebuild your onboarding assumptions — this is clearly where Nous Research wants new users to start. All facts above come from the official v0.21.5 release notes published on GitHub on 24 September 2026.
