ServiceStack MCP Server

An MCP (Model Context Protocol) Server that enables Claude to interact with ServiceStack APIs. This tool transforms your ServiceStack API metadata into an MCP server, allowing Claude to discover and invoke your APIs through natural language.

What is this?

This MCP server allows Claude to:

Discover all available APIs from your ServiceStack application
Understand the request/response schemas
Invoke APIs with proper parameters
Handle authentication when required

Getting Your ServiceStack API Metadata

Before using this tool, you need to export your ServiceStack API metadata to an app.json file. ServiceStack automatically generates this metadata at the /metadata/app.json endpoint of your application.

Download Your app.json

# Download from your ServiceStack application
curl https://your-api.com/metadata/app.json > app.json

# Or for local development
curl https://localhost:5001/metadata/app.json > app.json

Quick Start

Once you have your app.json file, you can run the MCP server:

npx mcp-apis ./app.json

You can also filter the APIs to only include those with a specific tag, e.g:

npx mcp-apis ./app.json --tag TechStacks

Or a specific API:

npx mcp-apis ./app.json --apis QueryPost

Or multiple APIs:

npx mcp-apis ./app.json --apis QueryPosts,CreatePost,UpdatePost,DeletePost
