Types

type Capabilities added in v0.19.0 

type Capabilities struct {
	Tools             []*mcp.Tool             `json:"tools" yaml:"tools"`
	Prompts           []*mcp.Prompt           `json:"prompts" yaml:"prompts"`

func (*Capabilities) Get added in v0.20.0 

func (c *Capabilities) Get(name string) any

Get finds any capability (tool, prompt, resource, or resource template) by name. Returns the capability if found, or nil if not found. Note that if there are duplicate names (e.g. a tool and a prompt with the same name) it will return the first found. We should therefore aim to avoid duplicate capability names.
