Your workspace, in your storage
Work with files, Markdown, CSV, HTML, Python and BPMN diagrams in your own S3-compatible bucket. There is no separate application database to copy your workspace into.
Self-hosted · MCP-based harness system
The mind of your business.
One store for everything your AI needs to run your business — knowledge base, skills, projects, operational tables, reports. Every agent reaches it through MCP, so nothing has to be re-explained twice.
Knowledge scattered across docs, chats and spreadsheets. Every new agent starts from zero and has to be told who you are and how you work — again.
One store. Your assistant, your coding tool, tomorrow's tool — all of them read and write through the same MCP connection, and stay current with each other.
Built for real operations
Harnios combines the company files, the MCP connection and the operational controls in one self-hosted application.
Work with files, Markdown, CSV, HTML, Python and BPMN diagrams in your own S3-compatible bucket. There is no separate application database to copy your workspace into.
Connect assistants with OAuth or personal access tokens. They use the same Company OS instructions, files and enabled tools, so work stays grounded in the same context.
Use the integrated chat, connect external MCP servers, share files with expiring links, send messages and run scheduled tasks from the same workspace.
Self-hosted. Your bucket, your credentials and your operating context stay under your control.
How it works
Wherever suits you — S3-compatible, self-hosted, your own server. Harnios doesn't lock you into one host.
Start with the structure your business needs: instructions, knowledge, projects, tables and reports. You and your assistants keep that shared context up to date.
Consult whichever AI chat you already use. It reads the same store, keeps it in order, and gets sharper about your business over time.
What it holds
Not five different tools with five different logins. One store, reachable by any MCP-capable agent.
