概要

What is MCP Test Servers?

MCP Test Servers is a collection of test servers implementing the Model Context Protocol (MCP). It provides over 50 pre-built servers for testing MCP features, from basic tool calls to complex OAuth flows and schema edge cases, aimed at developers validating MCP client behavior.

How to use MCP Test Servers?

Run any server with npx -y @msfeldstein/mcp-test-servers <server>, e.g. npx @msfeldstein/mcp-test-servers everything. A gallery page with one-click install buttons for Cursor is available at the GitHub Pages link. Configure the server in mcpServers JSON with the command and optional environment variables.

FAQ from MCP Test Servers

What dependencies are required to run MCP Test Servers?

Node.js and npx are required. No additional dependencies are needed—servers are fetched via npm.

How do I test the `everything` server comprehensively?

Start the everything server, then in Cursor use the /test-everything slash command. The AI agent will automatically execute all 20 test steps and provide a validation report.

Can I test OAuth flow issues?

Yes—servers like oauth-repro, oauth-debug, oauth-callback-test, oauth-edge-case, and oauth-bug-trigger are included to reproduce specific OAuth 2.0 discovery and callback bugs.

Where does the server’s data live?

No persistent data storage is used. All servers are stateless and run in memory; environment variables and MCP roots are provided by the client.

What transports are supported?

Servers use standard MCP transport (stdio by default). The sse-timeout and session-management servers demonstrate Streamable HTTP with SSE and session tracking.
