wasm-mcp serves read-only structured data from the WebAssembly core specification (https://github.com/WebAssembly/spec). Every response is deterministic over data pinned to a specific upstream commit and baked into the package at build time. Not affiliated with, endorsed by, or sponsored by the W3C WebAssembly Community Group or Working Group. Common workflow: 1. `spec_version` — call first when you need to cite the spec or report what you're reading. Returns the pinned upstream commit. 2. `instruction_search` — find an instruction from a partial name or symptom ("extend", "trunc", "0x6a") when you don't know the exact mnemonic. Returns ranked lightweight hits. 3. `instruction_get { mnemonic }` or `{ opcode }` — the full record for one instruction: opcode bytes, category, stack type signature, and validation/execution prose anchors + URLs. 4. `instruction_list { category? }` — enumerate instructions, filterable by category, introducing ve
