Transform

pub(open) trait Transform {
  fn tools(Self, Array[@moonbitstack/moonmcp/tools.Tool
Tool]) -> Array[@moonbitstack/moonmcp/tools.Tool
Tool] = _
  fn resources(Self, Array[@moonbitstack/moonmcp/resources.Resource
Resource]) -> Array[@moonbitstack/moonmcp/resources.Resource
Resource] = _
  fn templates(Self, Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]) -> Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate] = _
  fn prompts(Self, Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]) -> Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt] = _
}

A rewrite of the components a server offers (← FastMCP's transforms).

The server applies every transform it was given to the whole set, in the order they were added, each time the set is listed and before a call is looked up. A transform therefore sees its predecessor's output: the order is the meaning.

Every method has a default that leaves the set alone, so a transform implements only the kinds it touches.

Hidden

source

pub(all) struct Hidden {
  names : @moonbitlang/core/set.Set
Set[String]
}

Keep a component out of the listing, and out of reach: a call to a hidden name is answered as an unknown one.

impl Transform for Hidden

fn prompts(self : Hidden, prompts : Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]) -> Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]

source

fn resources(self : Hidden, resources : Array[@moonbitstack/moonmcp/resources.Resource
Resource]) -> Array[@moonbitstack/moonmcp/resources.Resource
Resource]

source

fn templates(self : Hidden, templates : Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]) -> Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]

source

fn tools(self : Hidden, tools : Array[@moonbitstack/moonmcp/tools.Tool
Tool]) -> Array[@moonbitstack/moonmcp/tools.Tool
Tool]

source

Hidden::hides

source

fn Hidden::hides(self : Hidden, name : String) -> Bool

Whether name is hidden.

Hidden::new

source

fn Hidden::new(names~ : Array[String]) -> Hidden

Hide the components named here — a tool or prompt name, a resource URI or a template pattern.

Hidden::prompts

source

fn Hidden::prompts(self : Hidden, prompts : Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]) -> Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]

Hidden::resources

source

fn Hidden::resources(self : Hidden, resources : Array[@moonbitstack/moonmcp/resources.Resource
Resource]) -> Array[@moonbitstack/moonmcp/resources.Resource
Resource]

Hidden::templates

source

fn Hidden::templates(self : Hidden, templates : Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]) -> Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]

Hidden::tools

source

fn Hidden::tools(self : Hidden, tools : Array[@moonbitstack/moonmcp/tools.Tool
Tool]) -> Array[@moonbitstack/moonmcp/tools.Tool
Tool]

Namespace

source

pub(all) struct Namespace {
  prefix : String
}

Put everything a server offers under prefix: a tool or prompt add becomes prefix_add, and a resource or template users://{id} becomes prefix+users://{id} (the prefix joins the scheme, so the URI keeps its shape and a template keeps its parameters).

prefix should be spelled the way a tool name is — letters, digits, underscores and hyphens — since that is what prefixed tool names become.

impl Transform for Namespace

fn prompts(self : Namespace, prompts : Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]) -> Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]

source

fn resources(self : Namespace, resources : Array[@moonbitstack/moonmcp/resources.Resource
Resource]) -> Array[@moonbitstack/moonmcp/resources.Resource
Resource]

source

fn templates(self : Namespace, templates : Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]) -> Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]

source

fn tools(self : Namespace, tools : Array[@moonbitstack/moonmcp/tools.Tool
Tool]) -> Array[@moonbitstack/moonmcp/tools.Tool
Tool]

source

Namespace::new

source

fn Namespace::new(prefix : String) -> Namespace

A namespace under prefix.

Namespace::prompts

source

fn Namespace::prompts(self : Namespace, prompts : Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]) -> Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]

Namespace::rename

source

fn Namespace::rename(self : Namespace, name : String) -> String

The name name takes inside the namespace.

Namespace::rename_uri

source

fn Namespace::rename_uri(self : Namespace, uri : String) -> String

The URI uri takes inside the namespace.

Namespace::resources

source

fn Namespace::resources(self : Namespace, resources : Array[@moonbitstack/moonmcp/resources.Resource
Resource]) -> Array[@moonbitstack/moonmcp/resources.Resource
Resource]

Namespace::templates

source

fn Namespace::templates(self : Namespace, templates : Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]) -> Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]

Namespace::tools

source

fn Namespace::tools(self : Namespace, tools : Array[@moonbitstack/moonmcp/tools.Tool
Tool]) -> Array[@moonbitstack/moonmcp/tools.Tool
Tool]

Tagged

source

pub(all) struct Tagged {
  any_of : @moonbitlang/core/set.Set
Set[String]
}

Offer only the components that carry one of these tags. A component without tags is held back, since a set chosen by tag is a set of tagged things.

impl Transform for Tagged

fn prompts(self : Tagged, prompts : Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]) -> Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]

source

fn resources(self : Tagged, resources : Array[@moonbitstack/moonmcp/resources.Resource
Resource]) -> Array[@moonbitstack/moonmcp/resources.Resource
Resource]

source

fn templates(self : Tagged, templates : Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]) -> Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]

source

fn tools(self : Tagged, tools : Array[@moonbitstack/moonmcp/tools.Tool
Tool]) -> Array[@moonbitstack/moonmcp/tools.Tool
Tool]

source

Tagged::keeps

source

fn Tagged::keeps(self : Tagged, tags : @moonbitlang/core/set.Set
Set[String]) -> Bool

Whether a component carrying tags passes.

Tagged::new

source

fn Tagged::new(any_of~ : Array[String]) -> Tagged

Keep the components tagged with any of any_of.

Tagged::prompts

source

fn Tagged::prompts(self : Tagged, prompts : Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]) -> Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]

Tagged::resources

source

fn Tagged::resources(self : Tagged, resources : Array[@moonbitstack/moonmcp/resources.Resource
Resource]) -> Array[@moonbitstack/moonmcp/resources.Resource
Resource]

Tagged::templates

source

fn Tagged::templates(self : Tagged, templates : Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]) -> Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate]

Tagged::tools

source

fn Tagged::tools(self : Tagged, tools : Array[@moonbitstack/moonmcp/tools.Tool
Tool]) -> Array[@moonbitstack/moonmcp/tools.Tool
Tool]

apply

source

fn apply(transforms : Array[&Transform], tools : Array[@moonbitstack/moonmcp/tools.Tool
Tool], resources : Array[@moonbitstack/moonmcp/resources.Resource
Resource], templates : Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate], prompts : Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt]) -> (Array[@moonbitstack/moonmcp/tools.Tool
Tool], Array[@moonbitstack/moonmcp/resources.Resource
Resource], Array[@moonbitstack/moonmcp/resources.ResourceTemplate
ResourceTemplate], Array[@moonbitstack/moonmcp/prompts.Prompt
Prompt])

Serve one set of components through every transform, in order.
