253The Tasks extension is specified in the [ext-tasks repository](https://github.com/modelcontextprotocol/ext-tasks). It uses the standard MCP [extension negotiation](/extensions/overview#negotiation) mechanism: clients declare support in the `extensions` field of the `io.modelcontextprotocol/clientCapabilities` they send in each request's `_meta`, and servers advertise theirs in the capabilities returned by [`server/discover`](/specification/draft/server/discover).
