Community Calls
wasmCloud Runtime Crate: Embedding Wasmtime & the Component Model
The October 15, 2025 wasmCloud community call dives into the Wasm component model through a new wasmCloud runtime crate. Brooks Townsend walks through the crate — an opinionated embedding of Wasmtime that auto-links components via workload resolution, adds host plugins for WASI and custom interfaces, and exposes a much-simplified host API. The conversation widens into how component instances are managed across requests, how that shapes WIT design, and the community's push toward common agentic protocols like MCP and ACP.
MCP Server as a Wasm Component: OpenAPI to MCP, JCO & Component Model
The October 8, 2025 wasmCloud community call shows off an MCP server as a Wasm component. Bailey Hayes builds a Model Context Protocol server from idiomatic TypeScript, generates its tools from an OpenAPI spec with a new wash plugin, and compiles the whole thing to a portable, sandboxed WebAssembly component via JCO and StarlingMonkey. Victor Adossi traces the road to running plain JavaScript and WASI Preview 3 components in Wasm, and Brooks Townsend lands the wasmCloud runtime crate into wash ahead of Q4 roadmap planning.
wasmCloud News: GitHub Actions Toolkit, Wash Attestation & WebGPU
For the latest WebAssembly news, the October 1, 2025 wasmCloud community call walks an end-to-end demo of a new GitHub Actions toolkit for the wash CLI — built around supply-chain security with binary attestation, SBOM generation via cargo auditable, and a language-agnostic build/publish flow. Bailey Hayes also previews a new non-interactive mode for CI and proposed volume mounts for wash plugins, while Colin Murphy and the team explore WebGPU, hybrid AI inferencing, and the road to the next version of wasmCloud and the Wasm component model.
WebAssembly on Kubernetes: the New wasmCloud Runtime Operator & WASI P3
The September 24, 2025 wasmCloud community call is all about running WebAssembly on Kubernetes. Lucas Fontes walks through a new Kubernetes-native runtime operator for wasmCloud v2 that stores all workload state in Kubernetes via custom resources (CRDs), aligns naming with pods, replica sets, and deployments, and replaces external capability providers with secure in-process host plugins. Bailey Hayes covers a wave of wash and setup-wash-action improvements for the next major version, and shares that Wasmtime has shipped the first WASI P3 release candidate.
wasmCloud V2: The Wasm Component Model & a Simplified Host
The September 17, 2025 wasmCloud community call is a deep dive into wasmCloud V2 — also called wasmCloud Next — Brooks Townsend's proposal for a "radical simplification" of the platform. He walks through a pull request that introduces a consolidated wasmcloud crate (merging the host, runtime, and core libraries), a simplified Host API focused on scheduling workloads built from WebAssembly components, host plugins that replace built-in capability providers and make the wRPC transport opt-in, and in-process component-to-component calls for components running on the same host. Brooks presents C4-style architecture diagrams for the new model, and Eric Gregory previews a next version of the docs.
