Server-side application for the Model Context Protocol inspector

The MCP inspector is a developer tool for testing and debugging MCP servers. The MCP Inspector consists of two main components that work together: MCP Inspector Client (MCPI): A React-based web UI that provides an interactive interface for testing and debugging MCP servers MCP Proxy (MCPP): A Node.js server that acts as a protocol bridge, connecting the web UI to MCP servers via various transport…

Inferred from the transports this listing declares (stdio). A client not listed here hasn’t been ruled out — it just isn’t something Forge can confirm.

Tools

No tool declarations found in the source1mo ago

Forge read 2 source files from the published package tarball and matched no MCP tool registrations.

Treat it as “not detected”, not as “exposes none”.

About

The MCP inspector is a developer tool for testing and debugging MCP servers. The MCP Inspector consists of two main components that work together: MCP Inspector Client (MCPI): A React-based web UI that provides an interactive interface for testing and debugging MCP servers MCP Proxy (MCPP): A Node.js server that acts as a protocol bridge, connecting the web UI to MCP servers via various transport methods (stdio, SSE, streamable-http) Note that the proxy is not a network proxy for intercepting…
