MCP Isn't Dead. You're Just Using It Wrong
Everyone and their gran have been saying that MCP is dead. But could it be that MCP's saving grace has been with us all along - hiding in plain sight? A feature buried in Claude Code's Jan 2026 release may have marked the most powerful development in MCP since its inception - and almost nobody noticed. Dynamic Tool Registration. Dynamic tool registration extends an MCP server's abilities beyond that of just a glorified swagger doc - allowing the server not just to list a static set of tools, but to dynamically add and remove new tools in real time as part of a stateful agent session.

But could it be that MCP's saving grace has been with us all along - hiding in plain sight? A feature buried in Claude Code's Jan 2026 release may have marked the most powerful development in MCP since its inception - and almost nobody noticed. Dynamic tool registration extends an MCP server's abilities above those of just a glorified swagger doc - allowing the server not just to list a static set of tools, but to dynamically add and remove new tools from that list in real time as part of a stateful agent session. Well for one it allows us to elegantly solve the main problem most people had with MCP in the first place - context bloat. By grouping our tools into collections of related…from commandable.ai

MCP PlaygroundNov 2025 · mcpplayground.io · ▲160MCP Playground is a Postman-style tool for MCP — inspect servers, execute tools live, test your client, all from the browser. Four things in one place: 1. Free hosted MCP servers — four public test servers anyone can point their client at: Echo (connectivity), Auth (Bearer token flow), Error (error handling), Complex (multi-tool schemas).No sign-up, just use the URL. 2. Server inspector — paste any remote MCP server URL, see all its tools/resources/prompts, execute them live, inspect the full JSON-RPC log. HTTP, SSE, and WebSocket all supported. 3. Registry — 10,000+ servers…

SpanlyJun 2026 · spanly.com · ▲77Hi HN, I'm Tim, solo founder of Spanly (https://spanly.com). I spent the last year working on MCP gateways, and debugging them with nothing better than HTTP-level APM was painful. Spanly runs its own MCP server and monitors it with itself, so I've been the first user of everything below. Spanly is observability for MCP servers, the protocol that lets agents like Claude and Cursor call your product's tools. It's a sidecar proxy, so it works with any language and requires zero code changes. Live demo (no signup): https://app.spanly.com/share/demo Sidecar source…

MCP Mesh – one endpoint for all your MCP servers (OSS self-hosted)Dec 2025 · github.com · ▲8Hey HN! I’m Gui from deco (decocms.com). We’ve been using this tool internally as the foundation for a few customer AI platforms, and today we’re open-sourcing it as MCP Mesh. MCP is quickly becoming the standard for agentic systems, but… once you go past a couple servers it turns into the same problems for every team: - M×N config sprawl (every client wired to every server, each with its own JSON + ports + retries) - Token + tool bloat (dumping tool definitions into every prompt doesn’t scale) - Credentials + blast radius (tokens scattered across clients, hard to audit, hard to revoke) - No…
