great stuff, Jakob! 🫡

Let's take a critical look at "A Critical Look at MCP."

Some Major Points™️ covered:

1. big security pain points of MCP
2. transports are not the bottleneck
3. oauth has been going great, really
4. real problems (see point 1 again + more)

🔗 in 🧵 (bless us oh algo lord)

I think a really advanced user is going to start to want to optimize, but mostly around the ability to design very specific host functions and custom host function signatures. Think of this like bindings to OS or host application system calls.

For most things we see, extism is more than enough!

I do think there is a lot of value in learning the fundamentals and going as deep as your curiosity will take you. But, this is too often where people give up and decide wasm is immature or rough around the edges.

It’s just a vm and an instruction set, so you need some abstractions to get started!

Otherwise, you’re going to start way too low-level, think about allocators & memory management, how to pass data across the guest/host boundary, and probably stop before you even get something working beyond the add(1,2) example.

I am biased, but the most beginner-friendly approach is to just get started with something that works out of the box, make progress & get a quick win.

For that, we made github.com/extism/extism

Once you start to see how the pieces fit together, then you can start to break down the abstractions.

thank you for having me on! 🙏

MCP & Wasm are like peanut butter and jelly. In episode 111 of @happypathprogramming.com, we take some bites into the best AI sandwich ever made with @nilslice.bsky.social:

blame the implementation not the protocol

thank you 🙏 glad you enjoyed

Extism - Make all software programmable | Confoo 2025 Extism is a cross-language plugin framework for building with WebAssembly​. It's goal is to make all software programmable.

Showed how to extend #frankenphp with an @extism.bsky.social / #wasi markdown middleware plugin, generating html at 3k req/s. Kudos to @dunglas.dev, FrankenPHP rocks!

well, of course #dylibso's mcp.run works with Deepseek models. Thanks for asking though. Here it is running via #mcpx4j with #Spring AI using the OpenAI connector, powered by @extism.bsky.social and the #Chicory Wasm runtime.

MCP for the JVM (...and Android!) | 🤖 Compile once, run anywhere? You bet! After our mcp.run OpenAI integration and some teasing, we're excited to launch mcpx4j, our client library for the JVM ecosystem.

We're really excited to announce the mcpx4j library: you can now plug mcp.run tools everywhere Java runs! Powered by the @extism.bsky.social #chicory #wasm runtime! docs.mcp.run/blog/2025/01...

This is what the dylibso team and I have been working on: a safe, portable way to install tools that Claude and other MCP clients can use.

Quickly and confidently installing tools from a number of different authors and immediately putting them to use in a Claude session has been eye-opening.

This? Oh, nothing. That's just Ollama+llama3.2 with @langchain4j.dev, fetching #wasm functions from my mcp.run profile to get directions from Google Maps and flights from the Amadeus service, running them using the #chicory pure-Java runtime

It will probably happen!

Recently, Satya Nadella made some bold (and wise) predictions about the future of SaaS and business applications on Brad Gerstner and Bill Gurley’s pod.

Is it a complete collapse? The App-ocalypse?

I think it’s close… but we’re actually saved by MCP, here’s how:

It's only been a handful of days since
@anthropic.com announced MCP, introducing a new standard to integrate software tools and data systems into AI applications.

I see a promising future for MCP, so much that we're shipping a whole product to help see it grow!
