    The server address to paste into ChatGPT settings:

    https://gw1-mcp.graphmaxer.workers.dev/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.

    Server tool list (8)

    Raw names from tools/list. Only developers need these.

    get_skillLook up a single GW1 skill by exact English name or by template skill id. Returns full stats (energy, activation, recharge, adrenaline, sacrifice), profession, attribute, campaign, elite flag and description. If the name is not found, returns the closest matches so you can correct spelling. Use this when you already know the exact skill; to discover skills by profession, attribute or name fragment, use search_skills instead.
    search_skillsSearch the full GW1 skill database by profession, attribute, campaign, elite flag or name fragment (valid values are documented per parameter). Returns compact records, at most `limit` of them alongside a `total` count of every match — a full page is not the whole result, page with offset. Use get_skill for full details.
    decode_templateDecode an in-game GW1 skill template code (e.g. "OwpiMypMBg1cxcBAMBdmtIKAA") into professions, attribute allocations and the 8 skills with their stats and descriptions. Whitespace and line wraps in the pasted code are tolerated. This decodes a SINGLE build code; for a multi-hero paw-ned2 team blob, use decode_pawned_team instead.
    decode_pawned_teamDecode a paw-ned2 team build blob (the 'pwnd0001...>...<' format shared on PvXwiki team pages and by the paw-ned2 tool) into its individual builds: player/hero label, description, and each skill bar fully decoded. Whitespace and line wraps in the pasted blob are tolerated. For a single (non-team) build code, use decode_template instead.
    encode_templateCompile a build (professions, attributes, 8 skills by exact English name) into an official in-game template code. The build is validated first; on rule violations the errors are returned instead of a code. Unknown skill names return closest-match suggestions. IMPORTANT: template codes MUST come from this tool — never write or guess a code by hand, hand-written codes are invalid in-game. If unsure, verify any code with decode_template.
    validate_buildCheck a build (professions, attributes, 8 skills by exact English name) against Guild Wars 1 rules: one elite max, profession/attribute ownership, primary attributes, duplicates, rank ranges. Returns { valid, errors, warnings } without encoding — use encode_template instead when you also want the template code, since it runs these same rules and refuses on any error.
    get_heroLook up a GW1 hero by name or by id (GWCA HeroID, matching the AccountExport plugin output). Returns profession, campaign and how the hero is unlocked. Remember: heroes can equip any skill unlocked at ACCOUNT level, but NO PvE-only skill at all — including Signet of Capture. validate_build with forHero=true reports each one as an error, not a warning. Use this for one known hero; to browse or filter the roster, use list_heroes instead.
    list_heroesList all GW1 heroes, optionally filtered by profession or campaign name. Useful for team-building: shows which professions are coverable by heroes and how each hero is unlocked.
