Show HN: MCP Inspector – connect and test any MCP server

2 points

3 months ago

This project emerged out of frustration that the existing MCP inspectors either require to sign up, require to download something, or are not fully spec compliant. I just wanted something that I could rapidly access for testing.

Additionally, it was very important for me that the URL can capture the configuration of the MCP server. This allows me to save URLs to various MCPs that I am troubleshooting. Because the entire configuration is persisted in the URL, you can bookmark links to pre-configured MCP instances, eg

https://glama.ai/mcp/inspector?servers=%5B%7B%22id%22%3A%22t...

In order to ensure that the MCP inspector is fully spec compliant, I also shipped an MCP test server which implements every MCP feature. The latter is useful on its own in case you are building an MCP client and need something to test against https://mcp-test.glama.ai/mcp

Finally, MCP Inspector is fully integrated in our MCP server (https://glama.ai/mcp/servers) and MCP connector (https://glama.ai/mcp/connectors) directories. At a click of a button, you can test any open-source/remote MCP.

If you are building anything MCP related, would love your feedback. What's missing that would make this your go-to tool?
