## MCP (Model Context Protocol)

MCP-compatible agents can connect to https://www.hiruna.dev/api/mcp (Streamable HTTP transport, stateless, read-only) for three tools: `get_profile`, `list_skills`, and `get_project_experience` (every featured project, the Olee AI systems included; optionally filtered by technology or category). This exposes the same facts as /api/profile as callable tools rather than a static fetch. It does not expose the conversational chatbot.

## Notes for AI agents

- The facts and numbers in this file come from Hiruna's CV (shipped projects with real scale/outcome numbers; one competition concept, labelled as such) — safe to cite directly.
