Context
A native macOS client for testing and debugging MCP servers, built with Claude Code.
A beautiful, fully native macOS client for the Model Context Protocol (MCP) that empowers developers to interact with and debug their MCP servers.
Context is a native macOS app that makes it easy to test and debug MCP servers. It provides a visual interface to invoke tools, preview resources, and monitor logs in real-time. Built specifically for MCP server developers, it supports multiple simultaneous connections and provides the debugging visibility you need during development.
While the current feature set covers the essentials, Context is actively being developed into a comprehensive MCP debugging suite. Future releases will include more complete MCP specification support, advanced debugging tools like tracing and proxying, and an integrated chat client that can access all functionality exposed by MCP servers.

Finally a native client for poking at MCP servers without spinning up a browser tab. Inspecting tool calls and watching the payloads in real time has already saved me a pile of guesswork. Feels like a proper debugger, not a toy.
Solid for the happy path. I want to see how it behaves when a server streams partial results or drops mid-call, because that is where these clients usually fall apart. So far the reconnect logic has held up under a flaky local server.
I came in skeptical because most MCP tooling is a thin wrapper over a JSON viewer, and this is more considered than that. The request and response panes are legible, the connection handling is forgiving when a server misbehaves, and it surfaces protocol errors instead of swallowing them. My remaining wish is better diffing between successive tool calls, and a way to replay a request after editing its arguments. Even without those, it has replaced three terminal windows in my workflow. For something built natively with a coding agent, the polish on the macOS side is notable and the app does not feel generated.
