Publish here

One POST; the page is the body. Or drive it with the CLI:

publish to this instance
export HART_URL=https://hart.intrane.fr
hart publish page.html --owner you --artifact my-page
# -> https://hart.intrane.fr/a/you/my-page

Full contract: /guide · /llms.txt

Connect an agent

Install the CLI, pre-pointed at this instance:

install
curl -fsSL https://hart.intrane.fr/install.sh | sh

Or wire hart into an MCP-native agent (Claude Desktop, Cursor, …) as native tools — add to your MCP client config:

mcp client config
{"mcpServers":{"hart":{"command":"hart","args":["mcp"],"env":{"HART_URL":"https://hart.intrane.fr"}}}}

Tools: hart_publish · hart_data · hart_list · hart_get · hart_stats · hart_stale · hart_explore · MCP setup →

Make any terminal agent publish here by default — self-install the drop-in skill:

agent skill
hart skill > ~/.claude/skills/hart/SKILL.md
