Hjarni is a hosted Markdown knowledge base for personal and team notes, folders, tags, and file attachments. It is designed to act as long-term memory for AI assistants like ChatGPT and Claude via built-in MCP access, alongside a REST API for scripts and automations.
Hjarni exposes an OAuth-protected MCP server at `https://hjarni.com/mcp` and a Bearer-token REST API at `https://hjarni.com/api/v1`; the MCP server also accepts personal API tokens for non-OAuth clients.

In Hjarni, go to Settings > Connections, create a token for your integration, and copy it. The REST API docs say to send it as Authorization: Bearer YOUR_API_TOKEN. The same personal API token can also be used against the MCP endpoint for clients that do not support OAuth. Start from the REST API reference.
For MCP clients that support OAuth, use Hjarni's OAuth 2.0 Authorization Code flow with PKCE discovered from OAuth authorization server metadata. Hjarni supports dynamic client registration at register; hosted clients may also use pre-approved redirect URIs documented in the MCP reference. Authorize the user via authorize and exchange the code at token.
