Configuration Plan & Exposition

Before being turned into an MCP Server endpoint, a reShapr Service must have a Configuration Plan defined. A Configuration Plan will allow you to define how your Service will be consumed by MCP Clients. You’ll define the backend endpoint the reShapr Gateway will target as well as the security options you want to apply to future expositions.

In a nutshell, a Configuration Plan will allow you to define:

  • The backend endpoint URL of the existing service or API implementation you’re targeting,
  • The list of the Service operations you’d like to expose - you can choose, for example to restrict access to read-only operations only, or to hide non-relevant operations,
  • The security options you’ll like to enable for securing the access of the MCP endpoints - you can choose to secure access with an API key or using an OAuth Authorization Server,
  • The required permissions needed to access the MCP Server tools, resources or prompts - you can specify additional scopes for the write operations for example.
  • The credentials Secret the MCP Server will present to authorize the access to the backend endpoint.

A reShapr Service can have multiple Configuration Plans that matches with different environments or lifecycle stages. A Configuration Plan is always associated to a specific version of a Service and has to be replicated for other versions.

Creating a Configuration Plan is not enough for your MCP Server to be ready and usable by your MCP Client. In order to do, you must expose - ie create an Exposition - of your Configuration Plan. This last step before consuming a reShapr MCP Server endpoint is a simple declaration that allows you to target a reShapr Gateway. As introduced in Why reShapr?, reShapr allows deployment on different types and locations of Gateways depending on your subscription plan.

Creating an exposition is a simple operation that just associate a Configuration Plan to a Gateway Group - a logical representation of gateways actually running MCP Servers. Check our next Gateway Group & Gateway section if you want to learn more.
