Nothing serious here today
Today is the operative word: we check Guild Wars 1 Build Compiler every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
decode
decode_pawned_team
Decode 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.
decode_template
Decode 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.
encode
encode_template
Compile 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.
hero
get_hero
Look 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.
heroes
list_heroes
List 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.
skill
get_skill
Look 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.
skills
search_skills
Search 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.
validate
validate_build
Check 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.

How MCP servers expose tools in the first place →
Is Guild Wars 1 Build Compiler working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 184 ms. The bar chart above shows every period we have measured.
How do I connect Guild Wars 1 Build Compiler?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Guild Wars 1 Build Compiler need an API key?
No. Guild Wars 1 Build Compiler completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Guild Wars 1 Build Compiler?
It answers our handshake in 184 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Guild Wars 1 Build Compiler open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at gw1-mcp.graphmaxer.workers.dev, which runs on its operator's own terms.
