Sushi Unshortens Short Hand Inputs (FSH Compiler)
Most developer tooling work still happens through a UI a human drives. Fsh MCP server moves it into the conversation instead. Sushi Unshortens Short Hand Inputs (FSH Compiler).
SUSHI (aka "SUSHI Unshortens Short Hand Inputs") is a reference implementation command-line interpreter/compiler for FHIR Shorthand (FSH).
The server publishes 8 tools. What each one is for:
Maintainers — This project is maintained by the HL7 communityTask — Descriptionbuild — compiles src//*.ts files to dist//*.js files using the TypeScript compiler (tsc)test — runs all unit tests using Jestlint — checks all src files to ensure they follow project code styles and rulesprettier — checks all src files to ensure they follow project formatting conventionscheck — runs all the checks performed as part of ci (test, lint, prettier)regression — runs regression against repositories found by FSHFinderThe server ships on npm as fsh-sushi, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Fsh's toolset — Maintainers, Task, build and 5 more — is a fair guide to whether it matches your workflow. It is maintained by cmoesel; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
