A value of 1 means "most important," and indicates that the data is
effectively required, while 0 means "least important," and indicates that
the data is entirely optional.

If not set, this is assumed to be false (the call was successful).

Any errors that originate from the tool SHOULD be reported inside the result
object, with `isError` set to true, _not_ as an MCP protocol-level error
response. Otherwise, the LLM would not be able to see that an error occurred
and self-correct.

servers to ask for specific directories or files to operate on. A common example
for roots is providing a set of repositories or directories a server should operate
on.

This request is typically used when the server needs to understand the file system
structure or access specific locations that the client has permission to read from.

Keys not declared here are currently left unspecified by the spec and are up
to the client to interpret.

The client SHOULD treat this as a substring of a model name; for example:

 - `sonnet` should match `claude-3-5-sonnet-20241022`, `claude-3-sonnet-20240229`, etc.
 - `claude` should match any Claude model

The client MAY also map the string to a different provider's model name or a different model family, as long as it fills a similar niche; for example:

# definitions.ModelPreferences.description
The server's preferences for model selection, requested of the client during sampling.

Because LLMs can vary along multiple dimensions, choosing the "best" model is
rarely straightforward.  Different models excel in different areas—some are
faster but less capable, others are more capable but more expensive, and so
on. This interface allows servers to express their priorities across multiple
dimensions to help clients make an appropriate selection for their use case.

These preferences are always advisory. The client MAY ignore them. It is also
up to the client to decide how to interpret these preferences and how to
balance them against other considerations.

is not important, while a value of 1 means cost is the most important
factor.

# definitions.ModelPreferences.properties.hints.description

MAY still use the priorities to select from ambiguous matches.

# definitions.ModelPreferences.properties.intelligencePriority.description
How much to prioritize intelligence and capabilities when selecting a
model. A value of 0 means intelligence is not important, while a value of 1
means intelligence is the most important factor.
