Unclear It is not clear what turns MCP tasks on, so it is not known whether this works for every user.
What
MCP servers are outside programs that give Claude Code extra tools. Some of their tools run as tasks, which are jobs that can keep going for a while. A program connected to a Claude Code session from elsewhere can now send it an MCP task request. The request can do one of these:
Claude Code only serves the request when all of these hold:
the request carries a ticket
the request carries an interface version
MCP tasks are enabled
The request is refused when the tool is denied, or when the tool has PostToolUse hooks. A hook is a command you set up to run automatically at a certain moment, and PostToolUse hooks run after a tool call succeeds.
Why
This lets a remote connection do more with tools that a session hosts, including long-running MCP tasks.
