I use almost no MCPs and feel like I'm not missing out on anything, I just use APIs directly or CLIs. I honestly don't quite see the point of MCPs any longer.
Ask HN: Who is using MCP in production?

#102We (Prostack, UK managed hosting) launched an MCP server for our control panel- https://mcp.prostack.uk - to allow users to interact with Claude/Cursor etc, for debugging & deployment.
"Why is my site showing an error", "Deploy this project" etc are the key flows, and users have been building on top of them. It's a nice link between dev & prod, and a great debugging assistant. It's been very well received so far.
Implementation was pretty straightforward (tools mapped to our API) with appropriate guardrails for destructive actions.

#103I recently started using it as a way to make my own custom software available to regular ChatGPT and Claude, both of which support MCP if you dig around deep enough. Here's my TIL: https://til.simonwillison.net/llms/mcp-in-claude-and-chatgpt
me three (at this point)
I've developed and deployed my own self hosted (on cloudflare / workerd) tool here https://github.com/TAJD/projektor and the key part was to be able to add it as a custom mcp server

#104In my previous company we used MCP for voice agents. It was easy to use open-source mcps, since we did all the oauth and account management on our side. This also makes it easy for customers to bring their internal tools in a standardized format.

#105MCP usage is at an all-time peak - 17M daily (!) downloads of the official SDKs.
We're using MCP for virtually all our SaaS and infra providers (CRM, ATS, banking and accounting, Notion, Linear, all dev tools and hosting platforms) it's become a hard requirement in our buy bechmark. No MCP = NOGO
The advantages are:
- baked-in auth: no need to configure anything, it just works with our employees accounts
- one click install with Codex Plugins and Claude Connectors

#106I (SiteSpeakAI) use MCP in production in 2 ways, to analyze usage and make improvements to the app itself to hopefully improve the customer experience, and then also as a feature for each customer so they can interact with their own cx install and monitor / improve prompts etc. Been really useful, but important to note most customers are at least a bit tech savvy, so MCP makes sense for them.
Don't think it would be that useful for non-tech users.

#107I use MCP for Stackography, a tool I built that visualises my estate (hosts, apps, databases, tunnels, proxies etc), showing a force-directed graph, which includes live health, and a flexible search tool. It's very good for answering questions like "what stuff am I running under Docker", or "show me everything that makes up app X". Also shows the history of changes, summarised by LLM.
MCP is useful because it has instructions to Claude (or the agent of your choice) that tell it how and when to manage the graph. Integrating with Stackography is a one-line operation:
claude mcp add --transport http stackography https://app.stackography.com/mcp --header "Authorization: Bearer stk_...

#108We (HappySupport [1], help center with lots of automation) recently added an MCP server - this was highly requested. Our users are using it to reorganize their help center, answer questions (internally) and to create/edit/move/publish/unpublish or delete articles.
It was also pretty handy for importing existing documentation from obscure providers without having to build an integration for each of them.
We also added WebMCP [2] for agents to consume our public documentation/help center, but we haven't seen it used yet.
An API would work for all of these cases too, but since customers are using it in their AI tools anyway, MCP is just simpler for them.

#109At Adidas we use MCP in production, both flavors stdio and remote. Remote is more for secure autonomous agents or agents workflows and stdio is more intended for local development. So far we are good with this still don't see the point of A2A except some really specific cases, if you have the tools and a smart model do you need really split with different agents?
Re: Ask HN: Who is using MCP in production?
#110MCPs are diminishing in value a bit, because AI Agents are getting smarter about using API/CLIs. For example, I use gh cli via Claude instead of their MCP, because I already had cli setup, so no need to use MCP. MCPs can potentially have great value if they cross multiple sources and combine results. For example at work we use an in-house MCP for log/metrics search across five different (legacy) systems. It finds cor…
I use MCPs all the time, but just like in your case: they're my own MCP servers.
They do exactly what I want and how I want it. They expose just the information and the features I want the LLM to have. And just like in your case, it combines multiple sources of information into 1 response.
