Classes

​
FastMCPMeta

​
FastMCPComponent

Base class for FastMCP tools, prompts, resources, and resource templates. Methods:

​
key 

key(self) -> str
The key of the component. This is used for internal bookkeeping and may reflect e.g. prefixes or other identifiers. You should not depend on keys having a certain value, as the same tool loaded from different hierarchies of servers may have different keys.

​
get_meta 

get_meta(self, include_fastmcp_meta: bool | None = None) -> dict[str, Any] | None
Get the meta information about the component. If include_fastmcp_meta is True, a _fastmcp key will be added to the meta, containing a tags field with the tags of the component.

​
model_copy 

model_copy(self) -> Self
Create a copy of the component. Args:
  • update: A dictionary of fields to update.
  • deep: Whether to deep copy the component.
  • key: The key to use for the copy.

​
enable 

enable(self) -> None
Enable the component.

​
disable 

disable(self) -> None
Disable the component.

​
copy 

copy(self) -> Self
Create a copy of the component.

​
MirroredComponent

Base class for components that are mirrored from a remote server. Mirrored components cannot be enabled or disabled directly. Call copy() first to create a local version you can modify. Methods:

​
enable 

enable(self) -> None
Enable the component.

​
disable 

disable(self) -> None
Disable the component.

​
copy 

copy(self) -> Self
Create a copy of the component that can be modified.
