Switching from OpenClaw to Hermes Agent cut session costs 5-10x
A developer describes building a tool called NeuralMind: a fully local, persistent code for , connected to Hermes Agent through MCP, a standard way for agents to link up with outside tools. With this setup, the agent starts every session already knowing the codebase's structure, which files belong together, and which files usually get edited next, so it no longer has to re-read context it already understood. That change reportedly made sessions about 5-10x cheaper.
Before this, OpenClaw had been the daily driver for months. Its strengths were a flexible , a skill system, a with planner and developer bots, and Slack and Telegram integration. But maintenance became a burden: a Python 3.10 dependency required constant workarounds, the skill hub called clawhub was partly broken with about half of installs failing, scheduled cron jobs didn't survive restarts, and the relied only on SQLite with no compression, causing sessions to balloon in size.
Those problems led to searching for alternatives, and Hermes Agent from stood out because of its active development.
Key points
- NeuralMind is a fully local, persistent code-memory tool for , released on GitHub
- Connecting it to Hermes Agent via MCP lets the agent skip re-reading each session
- This reportedly cut session costs by about 5-10x
- The previous tool, OpenClaw, suffered from a Python 3.10 dependency, a partly broken skill hub, cron jobs not persisting, and memory bloat
- The switch to Hermes Agent () was driven by its active development
