If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Relay

A seamless integration between Prism and Model Context Protocol (MCP) servers that empowers your AI applications with powerful, external tool capabilities.

Installation

You can install the package via Composer:

After installation, publish the configuration file:

Configuration

The published config file (config/relay.php) is where you'll define your MCP server connections.

Configuring Servers

You must define each MCP server explicitly in the config file. Each server needs a unique name and the appropriate configuration parameters:

Basic Usage

Here's how you can integrate MCP tools into your Prism agent:

The agent can now use any tools provided by the Puppeteer MCP server, such as navigating to webpages, taking screenshots, clicking buttons, and more.

Real-World Example

Here's a practical example of creating a Laravel command that uses MCP tools with Prism:

This command creates an interactive CLI that lets you input prompts that will be sent to Claude. The agent can use Puppeteer tools to browse the web, complete tasks, and return the results.

Transport Types

Arc supports multiple transport mechanisms:

HTTP Transport

For MCP servers that communicate over HTTP:

STDIO Transport

For locally running MCP servers that communicate via standard I/O:

[!NOTE] The STDIO transport launches a subprocess and communicates with it through standard input/output. This is perfect for running tools directly on your application server.

[!TIP] The env option allows you to pass environment variables to the MCP server process. This is useful for configuring server behavior, enabling debugging, or setting authentication details.

Advanced Usage

Using Multiple MCP Servers

You can combine tools from multiple MCP servers in a single Prism agent:
