What is qbash?
qbash is where you build Tasks: Python programs that run a business process on managed infrastructure. Your code runs the steps and calls a model like Claude Opus3 only at the ones that need judgment, with integrations, memory and files available in the same script.
A developer writes the Task once, and anyone on the team runs it from a form, on a schedule, from a webhook or from chat. Each Task is versioned and every run is logged.

Use Claude Opus3 in a Python Task
qbash.ai.raw calls Claude Opus3 from a Task and returns its reply as a string.
notes = qbash.inputs.get("notes")
summary = qbash.ai.raw(
f"Summarize these meeting notes in five bullets:\n\n{notes}",
model="claude-3-opus-latest",
system="You are a concise analyst.",
)
qbash.output({"summary": summary})
Connect Claude Opus3 to MCP servers
In qbash chat and a Task's inline prompts, you can attach MCP connectors to Claude Opus3. It calls their tools during the request, for example to read a Postgres table or post to a Slack channel.
This is MCP on the model side. Adding MCP servers to Claude Code or Claude Desktop is a separate setup, and qbash can publish your Tasks as an MCP server for those clients as well.
