Returns version metadata (Java version, mappings flavor, loader options, build system, metadata file, doc links) for the chosen era. Use this when the user mentions a Minecraft version so you ground the rest of the answer.

Given a class concept or partial name (e.g. 'Block', 'TileEntity', 'EntityPlayerMP', 'Level', 'BlockPos'), returns the fully-qualified name in 1.8.9 (Forge/MCP) and modern 1.21+ (Mojang) along with notes on path or rename differences. Always returns top approximate matches even when the query doesn't hit exactly.

Given a task description like 'send chat message', 'open gui', 'register block', 'render hud', 'send useitem packet', returns the canonical snippet for both 1.8.9 and modern 1.21+. Searches BOTH the method/API table and the class-name table so partial class queries still surface useful info. Use when the user asks 'how do I X in ?'.

Given a method or class name from one era, suggests the equivalent in the other era. Looks across both classes and method tasks. Useful when porting code between 1.8.9 and 1.21+.

Given a plain-English description of a trigger ('player joins', 'tick', 'right click block'), returns the event class name in 1.8.9, NeoForge 1.21+, and Fabric 1.21+. Also tells you whether the event lives on the mod bus or game bus (NeoForge distinction).

Returns code examples for Mixin (Sponge/Fabric Mixin) patterns: @Inject HEAD/TAIL, @ModifyArg, @ModifyVariable, @Redirect, @WrapOperation, @Accessor, @Invoker, plus mixin config JSON skeletons for Fabric and NeoForge. Use when the user is wiring up a mixin and you need to remember the exact annotation shape.

Returns a list of common mistakes, breaking changes, and surprising behaviors per era. Filter by topic ('mixin', 'nbt', 'packets', 'fabric', 'mappings', etc.). Use proactively when the user starts a non-trivial task in a specific area.

Returns build.gradle, settings.gradle, and gradle.properties templates for a chosen era + loader combo. Pinned to current versions (NeoForge 21.10, Loom 1.10, Fabric API 0.131, Yarn 1.21.10+build.1, ForgeGradle 2.x for 1.8.9). Tell the user to bump to latest after copying.

Given a class name from either Yarn (Fabric) or Mojang official (NeoForge / modern Fabric) mappings, returns the equivalent. Useful when porting between Fabric on Yarn and NeoForge on Mojang, or when reading a wiki snippet that uses the other naming.

Enumerate every scaffold template id and its description.

Emits a code snippet (or config file body) for a given scenario, era, and loader. Run mc_list_scaffolds first to see valid kind values. Loader is forced to 'forge' for 1.8.9.

Returns the most relevant doc/wiki links to consult for a given era.

Live call to https://linkieapi.shedaniel.me/api/namespaces. Returns every mappings namespace (yarn, mojang, mojang_raw, quilt-mappings, mcp, legacy-yarn, feather, ...) and which Minecraft versions each one currently has. Use to confirm a version exists before searching it. By default filters to stable releases — pass includeUnstable=true to see snapshots, pre-releases, RCs.

Live full-text search against linkie's mappings database. Returns class/method/field results for ANY (namespace, version) combination linkie carries — no curation gap, no stale snapshot. Use this whenever the user asks 'what is X called in ?' or 'find all methods named foo in 1.21.11 yarn'. For 26.1.x, linkie currently 500s on the mojang_raw namespace — use mc_mojang_mappings instead for those versions.

Convenience wrapper over mc_mappings_search filtered to fields. The curated knowledge tables don't track fields at all, so this is the only way to ask 'what's the field name for X in ?'.

Bypasses linkie and fetches Mojang's client_mappings.txt straight from piston-meta.mojang.com, parses the proguard format, and searches it. Use this for any version linkie can't load — most importantly the 26.1 lineage (26.1, 26.1.1, 26.1.2) which linkie advertises but 500s on. Also useful when you want to verify a name against Mojang directly. First call for a version downloads the mapping (multi-MB) and caches it in-process; subsequent calls are instant.
