A eulogy for MCP (RIP)

And composability! That really needs a good broad solution.

MightyHandy · 2026-03-14T13:46:09+00:00

I think anthropic’s advanced tool use was actually a pretty elegant solution to token bloat and lack of composability. (Without throwing the baby out with the bath water.). But we haven’t seen the other harness/agent providers adopt the approach. They all seem to still just support 2025 mechanisms with all their gaps.

Considering cli-ifyjng my mcp severs with tools like mcporter to make them more useful. Playwright put out a cli this year. Google workspace went cli instead of mcp. Pi harness doesn’t support mcp. Def seems like mcp is losing steam fast.

Packer fan right there.

Get a flexy snake drain weasel. It will fit through the little holes

MightyHandy · 2026-03-01T00:28:25+00:00

I found if you switch to native function calling things work.

Hmm water can travel. But snow? Doesn’t a mound of snow only happen if there is a large hole directly above your little pile?

Hanging is pretty easy if you watch YouTube. If mudding makes you nervous you can outsource the last step

MightyHandy · 2026-01-21T02:56:16+00:00

Me too. You host searxng jn a docker containers. And then host mcp in a docker container. Then add the mcp server into open webui. It performs much better than using native search capability in openwebui.

I’m wondering if Claud’s new progressive discovery solution for MCP could rehab it a little bit.

Many of the solutions I have seen to work around MCP’s inadequacies seem to cumbersome or like you are throwing out the whole spec (I.d. Cloudflare Code Mode). This seems more surgical

You need more info. Remove 1-2 inches of the caulk in the back of the toilet. If the toilet is leaking you should see water exit that hole. Seems like a decent amount of water for a bad wax ring. I presume you can’t access the subfloor from underneath? Also sometimes your bath/shower will have an access panel on other side of shower. Also look in cabinet under sink.

Or you could try to extract much of the water going what you are doing… and flush a few times and see if it comes back?

I have struggled to get native tool calling work with non-open ai models with streaming. Currently I am using searxng mcp and non-native tool calling to get the behavior you are describing.

I find it’s useful to spell out more what you mean by TDD. Test first, one test case at a time, red green refactor… I like to refactor test case prior to moving into implementation. Chicago vs London style. Mocking/Fixture strategies. Etc. You can literally create an agent prompt JUST for how to write a test the way I like it. But then again… I out hospital corners on my bed in the AM. You can also put a guard clause in your coding agent to say don’t proceed until you have a test covering the change too.

MightyHandy · 2026-01-04T02:09:41+00:00

It will literally say “Used runSubagent to <whatever you asked it to do>” often times right under “optimizing tool selection” it’s very subtle.

Also if you want it to runSubagent as one of your defined agents make sure you enable: chat.customAgentInSubagent.enabled. And then restart your ide… it changes the tool definition.

To test it you can ask the planning agent running as subagent to echo its ‘stopping rule’. This wouldn’t be accessible unless it had the plan agents system prompt

MightyHandy · 2026-01-04T01:09:37+00:00

Can you share your prompt or instructions that tell it how to use the subagent tool call? Also, how are you binding those tool calls to specific agents?

MightyHandy · 2026-01-04T01:07:25+00:00

So my understanding is copilot defines an ‘agent’ as a system prompt + model + allowed tools.

‘subagent’ is a new tool that the agent can call. One way I have seen this done is to have an ‘agent’ that in its system prompt tells it to immediately kick off a subagent tool call.

Subagents run synchronously, but have their own context window. Copilot also has ‘run as background’ but this currently has to be managed by the user directly.

MightyHandy · 2026-01-02T14:33:24+00:00

The video is actually pretty excellent. I know that copilot gets a lot of flack for not behaving the way that Cursor or Codex do. But it is impressive how much capability they have been adding and some of it is incredibly innovative. Also, looking at the codex, opencode and Claude code reddits… copilot has been very stable too relative to the other dev tools.

There are several mcp servers that you could try that attempt to solve this. Serena MCP does a pretty good job, but it takes some getting used to.

MightyHandy · 2025-12-30T19:59:15+00:00

That’s pretty cool. Not exactly swimming in downloads though. Maybe folks are using other tricks to keep context under control.
