goalplanner-share-mcp

An MCP server that crafts RuneLite Goal Planner import strings (GPSHARE1: codes) from a structured, natural-language-friendly goal spec — so an assistant can turn "plan my Inferno prep: 90 Ranged, 70 Defence, then beat the Inferno" into a paste-ready code, confirming your intent before it emits anything.

Pure string generator — no plugin changes required. Verified byte-compatible with the plugin's own com.goalplanner.share.ShareCodec in both directions (the plugin decodes codes this tool produces, and this tool decodes codes the plugin produces).

What it does

• Two modes: import as a new named section, or as loose goals (which land in a "Shared goals" section).

• Multi-section codes (GPSHARE2): pass sections[] and ONE code carries several sections — each imports as its own section, in one undo. A section with targetDefault: true lands in the recipient's Default plan instead, REUSING existing equivalent goals (the in-game add dedup), so re-importing never duplicates. Single-section codes still emit the GPSHARE1: wire, which every plugin build imports; multi-section/default-target codes need a recent plugin build.

• Cross-section dependencies: in the sections[] form, a goal may requires/ orRequires a goal in a different section by its explicit id. The edge rides the bundle-level crossEdges wire field (mirroring the plugin's CrossEdgeDto) and is rewired on import. Section-local ids always win; an id found in several other sections is ambiguous and dropped with a warning; cycles are checked across the whole bundle. The preview marks the link on the dependent goal:

  ═══ Section 2/2: "Inferno prep" ═══
  Ranged - Level 90   [Skill · Level 90 (5,346,332 xp)]  ✓ auto-tracks
    ↪ needs "Imbued heart" — from section 1 "Slayer"
    TzKal-Zuk   [Boss · TzKal-Zuk · 1 KC]  ✓ auto-tracks   ◀ final goal

• Simple goals or complex trees: goals are wired into prerequisite trees (AND via requires, OR via orRequires) by stable id. Diamonds and OR-groups are supported.

• Hybrid typing: recognized kinds become typed, auto-tracking goals; anything else falls back to a CUSTOM goal (imports fine, manual check-off). Every fallback, dropped edge, or cycle is reported as a warning.

• Confirm-first, preview by default: craft_import_string renders the goal list as it will import — section header, each goal with its type/target, prerequisites nested as a guide tree, and per-goal tracking badges — with no code emitted. The user eyeballs it and adjusts; the code is produced only on a follow-up call with confirm: true.

  The list is rendered in the same order and nesting the plugin shows — do-first prerequisites flush-left at the top; the dependent goal indented beneath them, with the final goal at the bottom:

  ┌─ Goal Planner import preview ─────────────────
  │ Section: "Inferno prep"  (created fresh on import; completed goals kept inline)
  │ 4 goal(s) · 4 auto-track · 0 manual/unverified
  │ Order: do-first at top → final goal at bottom (as shown in-game)
  └───────────────────────────────────────────────
  
  Ranged - Level 90   [Skill · Level 90 (5,346,332 xp)]  ✓ auto-tracks
  Defence - Level 70   [Skill · Level 70 (737,627 xp)]  ✓ auto-tracks
  Beat the Fight Caves   [Boss · TzTok-Jad · 1 KC]  ✓ auto-tracks
    Beat the Inferno   [Boss · TzKal-Zuk · 1 KC]  ✓ auto-tracks   ◀ final goal

Goal coverage

Boss names are generated from the plugin's BossKillData via npm run gen:bosses (reads $GOAL_PLANNER_REPO). The item table is generated from the OSRS cache objtypes.txt (JayArrowz mcp-osrs) via npm run gen:items (auto-discovers the mcp-osrs data dir, or set $OSRS_DATA_DIR) — placeholder_/cert_ variants filtered out since the plugin tracks an exact itemId. Item names that diverge from their internal codename (potions, Cannonball, …) resolve via a curated alias map or by you passing an itemId you looked up on the OSRS Wiki. A second generated layer (npm run gen:item-names, wiki prices mapping) adds authoritative display names for ~4.5k tradeables — so the codename-divergent tail (Armadyl crossbow, Amulet of torture, Voidwaker pieces) resolves without curation. Community nicknames (tbow, bp, shadow, scythe, zcb, dhcb, fero, rancour, blorva, fang kit, …) resolve by NAME REFERENCE through the generated tables (never hand-typed ids) and armour sets (full torva, fortified masori) are recognised too; loadout presets (maxed melee setup, maxed ranged, maxed mage) expand to a full BiS-ish kit; and a +/and-joined phrase (full masori + tbow, maxed melee + shadow) fans out into one auto-tracking item goal per piece (visible in the preview before you confirm).

The diary table is generated via npm run gen:diaries, which joins two sources: the plugin's AchievementDiaryData (area/tier structure + required values) with the numeric varbit ids from the OSRS cache varbittypes.txt — the symbolic VarbitID.<AREA>_DIARY_<TIER>_COMPLETE constants are matched by name to their cache ids (the runtime varbit the recipient reads).

The loadout presets are generated via npm run gen:loadouts (needs network), a hybrid: armour slots come from the OSRS Wiki Armour/Highest bonuses tables (so they stay current — e.g. Amulet of rancour), resolved to ids via the wiki's prices-mapping API; the weapon + cape are curated because the wiki ranks weapons by raw bonus, which picks slow non-DPS weapons (Zombie axe, Kodai wand). Loadout member ids can be newer than the objtypes snapshot, so they're treated as known.

The quest table is generated via npm run gen:quests, which runs the real RuneLite Quest enum (values()/name()/getName()) from the version-matched runelite-api jar in the local gradle cache — the recipient's QuestTracker does Quest.valueOf(questName), so the wire must carry the enum constant (DRAGON_SLAYER_II), and running the enum keeps the constant↔display pairing from ever drifting. The account-metric table (npm run gen:accounts) parses the plugin's AccountMetric.java (the tracker's AccountMetric.valueOf constants + each metric's sensible target range + leagues flags). The CA table (npm run gen:cas, needs network) fetches the OSRS Wiki combat_achievement bucket — the same table the plugin's WikiCaRepository loads — where the bucket id is the bit index (0–639) into the CA_TASK_COMPLETED varplayers.

Cross-language parity for all three Phase-2 types is proven the same way as Phase 1: the plugin's real ShareCodec decoded a TS-crafted code and Quest.valueOf / AccountMetric.valueOf / the caTaskId range check resolved on the Java side (throwaway JUnit test, removed after the run).

Real-world corpus test

test/clan-corpus.test.ts runs ~140 labeled goals collected from a clan Discord (test/fixtures/clan-discord-goals-raw.txt, verbatim) through the full builder — community shorthand, KC goals, account milestones ("Elite CAs" → CA points @ 1064), and the lines that legitimately fall to CUSTOM (greenlogs, outfits, minigames). Add new community examples there; the test names each line so a regression reads as English.

Tools

• craft_import_string — { mode?, sectionName?, sectionColorRgb?, sharedBy?, goals[]?, sections[]?, confirm? } (sections[] = multi-section/default-target form; each entry is { name?, sectionColorRgb?, targetDefault?, goals[] }). Without confirm: human-readable preview + warnings, no code. With confirm: true: the paste-ready code (GPSHARE1: single-section, GPSHARE2: multi-section).

• decode_import_string — { code }. Decodes any GPSHARE1:/GPSHARE2: code (even embedded in surrounding text) into a readable breakdown for verification — sections, identifiers, prerequisite tree, per-goal desc:/tooltip: echo, and a Cross-section dependencies list with resolved goal names:

  ── Cross-section dependencies (1) ──
    • "TzKal-Zuk" (section 2 "Inferno prep") requires "Imbued heart" (section 1 "Slayer")

• list_supported_goals — what auto-tracks vs. falls back, plus the skill names.

Goal spec fields

id, type ("skill" / "custom" / a GoalType name), name, description, requires[], orRequires[], and per kind: skills use skill + level or xp; CUSTOM uses colorRgb, tooltip; ITEM_GRIND uses name (resolved to an itemId) or an explicit itemId, plus targetValue (quantity); QUEST uses name (resolved) or explicit questName (enum constant); ACCOUNT uses name or explicit accountMetric plus targetValue; COMBAT_ACHIEVEMENT uses name (exact task) or explicit caTaskId.

Register in Claude

After npm run build, register the server. Project scope — a .mcp.json at a project root (committable; activates when Claude Code runs in that project):

{
  "mcpServers": {
    "goalplanner-share": { "type": "stdio", "command": "node", "args": ["dist/index.js"] }
  }
}

Use a relative dist/index.js only in this repo's own .mcp.json (cwd = repo root). For a .mcp.json in any other project, or for user scope (~/.claude.json → top-level mcpServers, available everywhere), use the absolute path:

{
  "mcpServers": {
    "goalplanner-share": {
      "type": "stdio",
      "command": "node",
      "args": ["/absolute/path/to/goalplanner-share-mcp/dist/index.js"]
    }
  }
}

The server loads at Claude Code startup, so a newly-registered server appears in the next session. Claude Desktop uses the same block in claude_desktop_config.json.

Deploying changes

There is no hosted or remote deployment — this is a local stdio MCP server. Each user runs it from dist/index.js on their own machine (the mcpServers block above); the client spawns it over stdio at startup.

Because the client runs the built dist/, not the TypeScript source, changes only take effect after a rebuild:

1. Pull / make your edits (source lives in src/; reference data in src/refdata/).

2. npm run build — dist/ is gitignored, so this is always a fresh local build, never committed.

3. Restart the client (or reconnect the server) so the new dist/ is loaded — it's read once at startup.

Skipping the rebuild is the usual cause of a stale server serving old data (e.g. regenerated refdata/ that hasn't been compiled into dist/ yet). If you regenerate reference data with any npm run gen:* script, follow it with npm run build before the change reaches the running server.

Format

GPSHARE1:<base64url-nopad( gzip( JSON of ShareBundle ) )>

Mirrors the plugin's ShareBundle / GoalShareDto / TagShareDto. The importer is tolerant: unknown goal types are skipped, strings are length-clamped, edges pointing outside the bundle are dropped, and every import lands in a new user section.
