Hermes<br>Agent

The self-improving AI agent that runs on your server. Layered memory that accumulates across sessions, a cron scheduler that fires while you're offline, and a skills system that saves reusable procedures automatically.

The core idea

Most tools are excellent in the moment and weak over time

Memory is no longer a differentiator on its own. ChatGPT, Claude, Cursor, and GitHub Copilot all have some form of memory now. With GPT-5.5 and Claude Mythos pushing the frontier in April 2026, Anthropic, OpenAI, and Microsoft are all shipping scheduling and agent features. The category boundaries that existed twelve months ago are blurring fast.

The distinction that matters is not "has memory" vs. "has no memory." It's whether context persists across sessions automatically , whether execution happens on hardware you control , whether you can reach the same agent identity from any device , and whether the system gets meaningfully better at your workflow over time without manual configuration.

Hermes answers yes to all four. It runs as a persistent process on your server. Memory is markdown files in ~/.hermes/. The same agent that answered your Telegram message at 9am is available in your terminal at 2pm, with full context.

Why synthesis matters: The market is converging. Chat assistants added scheduling. Editors shipped cloud agents. CLIs are getting skills. Any single feature is available somewhere else. The value is having all of them in one self-hosted system, running continuously, with a persistent identity that accumulates real knowledge of your stack over time.

Session-scoped tool

You → [Tool] → Answer → Done

(some tools carry memory, but execution is stateless)

Persistent agent

You ↔ [Hermes] ↔ (memory, skills,

schedule, tools,

surfaces)

Memory: ~/.hermes/ (markdown files, editable)

Skills: auto-written from experience

Schedule: cron, runs while you sleep

Surfaces: Telegram &middot; Discord &middot; Slack &middot; browser

Model: your choice, swap anytime

Three pillars

What makes it different

Memory that compounds

Layered memory system: user profile, agent memory, skills, and session history. All stored locally as readable, editable markdown files at ~/.hermes/.

Survives every reboot and model swap

8 optional external memory providers

You never configure it manually

Portable, inspectable, deletable

Self-improving skills

The agent writes its own skills from experience. Compatible with agentskills.io open standard and shareable via Skills Hub.

Skills docs →

MCP integration

Connect to any MCP server. Hermes can also expose itself as an MCP server for Claude Code, Cursor, or Codex.

MCP docs →

Voice mode

Real-time voice in CLI (Ctrl+B to record), Telegram voice bubbles, Discord voice channels. Supports faster-whisper locally or Groq/OpenAI Whisper.

Voice docs →

6 terminal backends

Local, Docker, SSH, Daytona, Singularity, Modal. Run execution anywhere from a $5 VPS to serverless cloud, sandboxed as needed.
