Functions ¶
func GetCompatibleSource ¶
func GetCompatibleSource[T any](resourceMgr SourceProvider, sourceName, toolName, toolType string) (T, error)
func IsAuthorized ¶
Helper function that returns if a tool invocation request is authorized
func IsValidName ¶
func Register ¶
func Register(resourceType string, factory ToolConfigFactory) bool
Register allows individual tool packages to register their configuration factory function. This is typically called from an init() function in the tool's package. It associates a 'type' string with a function that can produce the specific ToolConfig type. It returns true if the registration was successful, and false if a tool with the same type was already registered.
Types ¶
type AccessToken ¶
type AccessToken string
func (AccessToken) ParseBearerToken ¶
func (token AccessToken) ParseBearerToken() (string, error)
type BaseTool ¶ added in v1.4.0
type BaseTool[T ToolMeta] struct { Cfg T StaticParameters parameters.Parameters // contains filtered or unexported fields }
BaseTool provides default implementations of various methods on the Tool interface. Tools embed BaseTool to drop their boilerplate and override only methods that need custom behavior.
func NewBaseTool ¶ added in v1.4.0
func NewBaseTool[T ToolMeta](cfg T, annotations *ToolAnnotations, metadata Manifest, staticParameters parameters.Parameters) BaseTool[T]
NewBaseTool constructs a BaseTool from a resolved Config (typically the per-tool Config after Initialize has filled in defaults), the resolved annotations, the precomputed Manifest, and the tool's static parameters.
func (BaseTool[T]) Authorized ¶ added in v1.4.0
func (BaseTool[T]) EmbedParams ¶ added in v1.4.0
func (b BaseTool[T]) EmbedParams(ctx context.Context, paramValues parameters.ParamValues, embeddingModelsMap map[string]embeddingmodels.EmbeddingModel) (parameters.ParamValues, error)
func (BaseTool[T]) GetAnnotations ¶ added in v1.4.0
func (b BaseTool[T]) GetAnnotations() *ToolAnnotations
func (BaseTool[T]) GetAuthRequired ¶ added in v1.4.0
func (BaseTool[T]) GetAuthTokenHeaderName ¶ added in v1.4.0
func (b BaseTool[T]) GetAuthTokenHeaderName(_ SourceProvider) (string, error)
func (BaseTool[T]) GetDescription ¶ added in v1.4.0
func (BaseTool[T]) GetParameters ¶ added in v1.4.0
func (b BaseTool[T]) GetParameters() parameters.Parameters
func (BaseTool[T]) GetScopesRequired ¶ added in v1.4.0
func (BaseTool[T]) RequiresClientAuthorization ¶ added in v1.4.0
func (b BaseTool[T]) RequiresClientAuthorization(_ SourceProvider) (bool, error)
type ConfigBase ¶ added in v1.4.0
type ConfigBase struct {
Name string `yaml:"name" validate:"required"`
Description string `yaml:"description"`
AuthRequired []string `yaml:"authRequired"`
ScopesRequired []string `yaml:"scopesRequired"`
}
ConfigBase owns the YAML fields that every tool's Config shares and that BaseTool reads through. Description is eagerly defaulted by the tool's Initialize (many prebuilt configs omit description: and rely on a canned per-tool string), so post-Initialize ConfigBase.Description holds the resolved value.
func (ConfigBase) GetAuthRequired ¶ added in v1.4.0
func (c ConfigBase) GetAuthRequired() []string
func (ConfigBase) GetDescription ¶ added in v1.4.0
func (c ConfigBase) GetDescription() string
func (ConfigBase) GetName ¶ added in v1.4.0
func (c ConfigBase) GetName() string
func (ConfigBase) GetScopesRequired ¶ added in v1.4.0
func (c ConfigBase) GetScopesRequired() []string
type HTTPMethod ¶
type HTTPMethod string
HTTPMethod is a string of a valid HTTP method (e.g "GET")
func (*HTTPMethod) UnmarshalYAML ¶
func (i *HTTPMethod) UnmarshalYAML(ctx context.Context, unmarshal func(interface{}) error) error
type Manifest ¶
type Manifest struct {
Description string `json:"description"`
Parameters []parameters.ParameterManifest `json:"parameters"`
AuthRequired []string `json:"authRequired"`
}
Manifest is the representation of tools sent to Client SDKs.
type SourceProvider ¶
SourceProvider defines the minimal view of the server.ResourceManager that the Tool package needs. This is implemented to prevent import cycles.
type Tool ¶
type Tool interface {
GetName() string
GetDescription() string
GetAuthRequired() []string
GetAnnotations() *ToolAnnotations
Invoke(context.Context, SourceProvider, parameters.ParamValues, AccessToken) (any, util.ToolboxError)
EmbedParams(context.Context, parameters.ParamValues, map[string]embeddingmodels.EmbeddingModel) (parameters.ParamValues, error)
Manifest() Manifest
Authorized([]string) bool
RequiresClientAuthorization(SourceProvider) (bool, error)
ToConfig() ToolConfig
GetAuthTokenHeaderName(SourceProvider) (string, error)
GetParameters() parameters.Parameters
GetScopesRequired() []string
}
type ToolAnnotations ¶
type ToolAnnotations struct {
DestructiveHint *bool `json:"destructiveHint,omitempty" yaml:"destructiveHint,omitempty"`
IdempotentHint *bool `json:"idempotentHint,omitempty" yaml:"idempotentHint,omitempty"`
OpenWorldHint *bool `json:"openWorldHint,omitempty" yaml:"openWorldHint,omitempty"`
ReadOnlyHint *bool `json:"readOnlyHint,omitempty" yaml:"readOnlyHint,omitempty"`
}
https://modelcontextprotocol.io/specification/2025-06-18/schema#toolannotations
func GetAnnotationsOrDefault ¶
func GetAnnotationsOrDefault(annotations *ToolAnnotations, defaultFn func() *ToolAnnotations) *ToolAnnotations
GetAnnotationsOrDefault returns the provided annotations if non-nil, otherwise returns the result of calling defaultFn.
func NewDestructiveAnnotations ¶
func NewDestructiveAnnotations() *ToolAnnotations
NewDestructiveAnnotations creates default annotations for a destructive tool. Use this for tools that create, update, or delete data.
func NewReadOnlyAnnotations ¶
func NewReadOnlyAnnotations() *ToolAnnotations
NewReadOnlyAnnotations creates default annotations for a read-only tool. Use this for tools that only query/fetch data without side effects.
func NewWriteAnnotations ¶ added in v1.4.0
func NewWriteAnnotations() *ToolAnnotations
NewWriteAnnotations creates default annotations for a non-destructive write tool: ReadOnlyHint is false, DestructiveHint is left unset.
type ToolConfig ¶
type ToolConfig interface {
ToolConfigType() string
Initialize(map[string]sources.Source) (Tool, error)
}
func DecodeConfig ¶
func DecodeConfig(ctx context.Context, resourceType string, name string, decoder *yaml.Decoder) (ToolConfig, error)
DecodeConfig looks up the registered factory for the given type and uses it to decode the tool configuration.
type ToolConfigFactory ¶
type ToolConfigFactory func(ctx context.Context, name string, decoder *yaml.Decoder) (ToolConfig, error)
ToolConfigFactory defines the signature for a function that creates and decodes a specific tool's configuration. It takes the context, the tool's name, and a YAML decoder to parse the config.
type ToolMeta ¶ added in v1.4.0
type ToolMeta interface {
GetName() string
GetDescription() string
GetAuthRequired() []string
GetScopesRequired() []string
}
ToolMeta is the read-only view BaseTool needs of any tool's Config. Tools satisfy it for free by embedding ConfigBase.
type Toolset ¶
type Toolset struct {
ToolsetConfig
Tools []*Tool `yaml:",inline"`
Manifest ToolsetManifest `yaml:",inline"`
// contains filtered or unexported fields
}
func (Toolset) ContainsTool ¶ added in v1.3.0
ContainsTool reports whether the toolset includes a tool with the given name. When built via Initialize, lookups are O(1) via toolNameSet; for Toolsets constructed directly (e.g., in tests), falls back to a linear scan of ToolNames.
func (Toolset) ToConfig ¶
func (t Toolset) ToConfig() ToolsetConfig
type ToolsetConfig ¶
func (ToolsetConfig) Initialize ¶
type ToolsetManifest ¶
