v0.8 — MCP Server for AI Coding Agents

jhansi now ships with an MCP server, making Petri natively usable by Claude Code, Cursor, Windsurf, and any MCP-compatible agent.

What's new

pip install jhansi now includes an MCP server. Three tools are exposed: create_sandbox, exec_code, and delete_sandbox. Works with any MCP-compatible AI coding agent. Configurable via JHANSI_BASE_URL — point it at your own Petri instance.

How to connect (Claude Code)

claude mcp add jhansi --scope user --env JHANSI_BASE_URL=http://localhost:8000 -- python -m jhansi.mcp_server

Then just ask your agent to run code in a sandbox.
