# Shared core

The shared core package provides infrastructure used by the Adobe app servers: safe argument normalization and script literals, path policy, script execution, structured results, MCP server construction, annotations and static script auditing.

## What this implementation covers

safe string/number/enum/path conversion; execution adapters; structured result parsing; failure detection; alias normalization; MCP tools/list and tools/call; annotation metadata; static API audits.

For feature-level detail and evidence, see the [Capability Atlas](https://creativemcp.com/capability-atlas.html).

## Connection and requirements

Runtime route

### How it reaches the app

A JavaScript library dependency, not a standalone MCP server and not a user-facing CLI.

Prerequisites

### What you need

Node.js 18+ when used by the packages. App runtimes are determined by the consuming server.

Package: `adobe-mcp-core`. Add it as a local stdio MCP server using [CLI & client configuration](https://creativemcp.com/docs/cli.html).

## API and content conventions

For contributors and integrators. The core README documents exports, executor options, error/result shape and tests. It does not provide Adobe app tools directly.

Discover the running package’s exact tool names and JSON input schemas through MCP `tools/list`. If the server provides `help`, use it to inspect a tool or category. Schemas from a different package version may not match.

Target and units: Core helpers are called by consuming packages; behavior such as application backend, paths and protocol is configured at the app-server layer.

## CLI and configuration

This package is launched as a persistent MCP process, not as a conventional one-shot CLI. Relevant settings documented by the package include:

`No standalone CLI configuration. Refer to each consuming package for environment variables and runtime behavior.`

Variable names and defaults are package-specific; consult the package README before changing them. File-operation permissions and bridge tokens should be configured in the client’s environment, not embedded in prompts or checked into source.

```
claude mcp add core -- npx -y adobe-mcp-core
```

For client-neutral JSON configuration and source-checkout commands, see [CLI & configuration](https://creativemcp.com/docs/cli.html).
