The hermes connectors page is the new Hermes Desktop screen that replaced the MCP tab in Hermes Agent v0.21.5, released on 24 September 2026 — everything you used to manage under MCP now lives under Connectors, and freshly installed plugins get a "Connect now" prompt so you can wire them up the moment they land. If you updated Hermes Desktop and went looking for the MCP tab, you have not lost anything: the same servers and integrations are there, reorganised under a name that matches what they actually do. This page covers exactly what moved, why the rename happened alongside the wider v0.21.5 interface changes, and how to work with the new screen day to day.

Everything on this page comes from the official Hermes Agent v0.21.5 release notes, published by Nous Research on GitHub on 24 September 2026 under the tag v2026.9.24. It is a patch release, but a heavy one — the notes describe roughly 460 pull requests rolled up since v0.21.4 — and the Connectors page is the change most people will notice first, because it renames a screen that sits in the middle of every serious Hermes setup.
What the Hermes Connectors Page Actually Is
According to the v0.21.5 release notes, the Connectors page replaces the MCP tab in Hermes Desktop and adds "Connect now" functionality for freshly installed plugins. In practice, that means the screen where you previously managed MCP servers — the Model Context Protocol integrations that let a Hermes agent reach tools outside itself — is now the single home for every external connection your agent has.
The rename matters more than it sounds. MCP is a protocol name, and protocol names make sense to developers who already know what the Model Context Protocol is: the bridge layer that lets an agent's brain reach real tools, files and services, which is the same bridge the Hermes MCP server guide walks through from the other direction. "Connectors" describes the outcome instead of the plumbing — this is where your agent connects to the outside world. Anyone who has watched a non-technical team member freeze at an acronym-labelled settings tab will understand why the label changed.
The functional upgrade is the "Connect now" flow. Under the old arrangement, installing a plugin and actually connecting it were separate chores in separate places. The release notes describe the new behaviour: install a plugin, and the Connectors page immediately offers to connect it. Fewer screens between "I found a useful integration" and "my agent can use it" is exactly the kind of friction removal that decides whether a feature gets adopted at all.
Where the MCP Tab Went: Finding Your Existing Setup
If you ran MCP servers before updating, the practical question is whether anything breaks. The release notes frame the Connectors page as a replacement for the MCP tab rather than a new system, so existing integrations carry across — the change is where you manage them, not how they run. Open Hermes Desktop after updating, look for Connectors in the place the MCP tab used to occupy, and your configured servers should be listed there.
Two related changes in the same release round out the picture. First, onboarding now offers catalog plugins alongside connectors, so a fresh install pitches you useful integrations from the first run instead of leaving you to discover them later. Second, Desktop gains a Simple/Advanced interface mode toggle, which suggests where the interface is heading: a simple mode that shows the controls most people need, with the full surface one toggle away. If you are setting Hermes Desktop up from scratch, the Hermes Desktop installation guide covers the base install that these screens now sit on top of.

Why the Connectors Page Landed in v0.21.5
The Connectors page did not arrive alone, and reading the release notes as a whole explains the thinking. Hermes Agent v0.21.5 ships what the notes call a Desktop plugin SDK wave: a composer draft API, session-list and row-decoration slots, sidebar navigation preferences, model-pill label providers, typed bridges for settings, skills, toolsets and profiles, a sandboxed embed primitive, an appearance-settings slot, and a public event bridge for plugin backends.
Put plainly: Nous Research is building Hermes Desktop into a platform that third-party plugins can extend properly, with official surfaces to plug into instead of hacks. A platform like that needs a front door where users see and manage everything their agent is connected to — and that front door is the Connectors page. The same release adds official Blender Lab and NVIDIA app integrations, complete French, German and Spanish Desktop catalogs, and new community plugins, all of which funnel through the same connect-and-manage flow. The best Hermes agent plugins round-up is the natural companion read once the page is in front of you, because the ecosystem this screen manages is growing by the release.
What Else Changed Around the Connectors Page in v0.21.5
The Connectors page is the headline for most Desktop users, but the release notes list several neighbouring changes worth knowing about, because they change how the whole app feels:
- Simple/Advanced interface modes — a new Desktop toggle between a pared-back interface and the full control surface.
- Custom model entry from the composer — type a custom model straight into the composer, alongside GPT-6 Sol, GPT-6 Terra, GPT-6 Luna and Claude Opus 5.5 being added to the Nous and OpenRouter catalogs.
- Per-profile multiplexer controls — stop, start and restart individual profiles under the host multiplexer, with a gateway.standalone setting to opt a profile out entirely.
- Function-key and dictation voice shortcuts — accessibility-focused voice control additions.
- Performance work — the notes describe hot-path optimisation across config loading, the tool registry, gateway message handling and the model picker.
The model catalog additions deserve a sentence of context: which brain you run behind Hermes changes what these connectors are worth, and the Goldie Bench write-up covers how the current crop of models compare in hands-on tests. If you pair Hermes with Anthropic's models specifically, the Hermes and Claude guide covers that pairing end to end.
Hermes Connectors Page vs the Old MCP Tab
| Question | MCP tab (up to v0.21.4) | Connectors page (v0.21.5) |
|---|---|---|
| Where integrations live | MCP tab in Desktop | Connectors page in Desktop |
| Connecting a new plugin | Install, then configure separately | "Connect now" offered on freshly installed plugins |
| Discovery for new users | Left to the user | Onboarding offers catalog plugins alongside connectors |
| Naming | Protocol-first (MCP) | Outcome-first (Connectors) |
| Underlying protocol | Model Context Protocol | Model Context Protocol — unchanged |
The bottom row is the reassurance that matters: nothing about the protocol changed. Servers you configured under the MCP tab are the same servers the Connectors page manages now.

Hermes Connectors Page FAQs
Where is the MCP tab in Hermes Desktop now?
It has been replaced by the Connectors page as of Hermes Agent v0.21.5, released 24 September 2026. Your existing MCP servers are managed there — the tab was renamed and upgraded, not removed.
Do I need to reconfigure my MCP servers after updating?
The release notes describe the Connectors page as a replacement for the MCP tab rather than a new integration system, so existing configurations carry across. Check the Connectors page after updating to confirm your servers are listed.
What does "Connect now" do?
When you install a new plugin, the Connectors page offers to connect it immediately rather than leaving you to find the configuration step yourself. It closes the gap between installing an integration and actually using it.
Is the Connectors page available in the CLI too?
The release notes describe the Connectors page as a Hermes Desktop change. CLI users manage integrations the way they did before; the v0.21.5 CLI additions are separate, such as the live dock for standing goals and queued prompts.
Verdict: A Rename That Signals the Roadmap
On its own, the Hermes connectors page is a quality-of-life change: clearer name, faster connection flow, better onboarding. Read alongside the plugin SDK wave in the same release, it is a statement of direction — Hermes Desktop is being built into a proper platform, and the screen where your agent meets the outside world just became a first-class citizen. Update to v0.21.5, open Connectors, and take five minutes to check what your agent is plugged into; that inventory is where most people find their next automation win. For the wider system this page slots into — mission control, memory and orchestration — start with the Agent OS guide, and see the Hermes Agent 0.21.4 update for what the previous patch laid down, or the Hermes Desktop app overview for the full application tour.
