Overview ¶

Package appcheck checks the server side of MCP Apps (io.modelcontextprotocol/ui, SEP-1865, stable 2026-01-26): tools that link a ui:// resource, the resources themselves (MIME type, HTML) and their security metadata (CSP domains, permissions), which is what a host shows before it renders an app.

Functions ¶

func Declare ¶

func Declare(opts *mcp.ClientOptions)

Declare adds the host capability to client options, so servers that register UI tools only for capable hosts expose them.

Types ¶

type AppInfo ¶

type AppInfo struct {
	URI         string              `json:"uri"`
	Tools       []string            `json:"tools"`         // tools rendering with it
	AppOnly     []string            `json:"appOnlyTools"`  // hidden from the model
	CSP         map[string][]string `json:"csp,omitempty"` // connectDomains, resourceDomains, …
	Permissions []string            `json:"permissions"`   // camera, microphone, …
	Domain      string              `json:"domain,omitempty"`
	Bytes       int                 `json:"bytes"`
}

AppInfo summarizes one UI resource and what it asks the host for.

type Report ¶

type Report struct {
	Declared bool      `json:"declared"` // server lists the extension in its capabilities
	Apps     []AppInfo `json:"apps"`
	Results  []Result  `json:"results"`
}

Report is the outcome of a check run.

func Run ¶

func Run(ctx context.Context, session *mcp.ClientSession) *Report

Run checks every tool that links a UI resource.

func (*Report) Failed ¶

func (r *Report) Failed() bool

Failed reports whether any check failed.

type Result ¶

type Result struct {
	Name   string `json:"name"`
	Status Status `json:"status"`
	Detail string `json:"detail,omitempty"`
}

Result is the outcome of one check.

type Status ¶

type Status string

Status of one check.

const (
	Pass Status = "PASS"
	Fail Status = "FAIL" // a MUST is violated
	Warn Status = "WARN" // a SHOULD is violated, deprecated or overly broad
	Info Status = "INFO"
)
