Hjarni
Connect a markdown note vault to your agent so coding sessions can read and update your own knowledge base instead of re-explaining context every time.
Overview
Hjarni is a MCP server for the Build phase that connects markdown notes to your AI coding agent via a hosted streamable-http endpoint.
What is this MCP server?
- Hosted streamable-http MCP at https://hjarni.com/mcp—no local server to maintain
- Markdown-first notes designed for both you and your AI assistant
- Remote MCP integration (v1.0.0) with source on GitHub (hjarni/hjarni-mcp)
- Fits agent workflows that need durable, editable context outside the chat window
- Productivity/knowledge layer across research, build, and iteration—not a one-shot codegen skill
- MCP server version 1.0.0
- Single remote endpoint: https://hjarni.com/mcp (type: streamable-http)
- Repository: github.com/hjarni/hjarni-mcp
What problem does it solve?
Your best product and technical context lives in markdown notes the agent cannot see unless you copy-paste it every session.
Who is it for?
Indie builders who already take markdown notes and want Claude Code or Cursor to read and maintain that knowledge during build and docs work.
Skip if: Teams that need a full wiki with granular ACLs, or anyone who only wants ephemeral chat context with no note discipline.
What do I get? / Deliverables
After you add the remote MCP server, your agent can ground answers and updates in your Hjarni note vault instead of improvising from scratch.
- Agent-readable access to your markdown note corpus
- Reduced copy-paste of specs and reference material into chats
- Notes that can be updated alongside agent-assisted work
Recommended MCP Servers
Journey fit
Canonical shelf on Build → Docs because solo builders most often wire knowledge bases while documenting products, runbooks, and agent instructions—not because notes are only useful during build. Docs is the right default facet for markdown note stores that back specs, ADRs, and SKILL-adjacent reference material your agent should cite during implementation.
How it compares
Hosted notes MCP integration, not an in-repo agent skill or static SKILL.md bundle.
Common Questions / FAQ
Who is com.hjarni/hjarni for?
Solo and indie developers who use markdown notes as a second brain and want their AI coding agent to use the same corpus while shipping.
When should I use com.hjarni/hjarni?
Use it when documentation, research snippets, or runbooks should stay in sync with agent-assisted coding—not when you only need one-off answers with no persistent notes.
How do I add com.hjarni/hjarni to my agent?
Register the MCP server in Claude Code, Cursor, or another MCP client using the remote URL https://hjarni.com/mcp (streamable-http) per your client’s MCP config format and Hjarni account requirements.
