poe-buildmcp 0.2.0

MCP server for Path of Exile game data

PoeMCP

An MCP server that gives any LLM access to Path of Exile game data — gems, unique items, passive tree nodes, item modifiers, maps, scarabs, live pricing, and Path of Building build parsing.

Data is fetched at runtime from poedb.tw, poe.ninja, and poewiki.net. No API key required.

Installation

Requirements

• Claude Desktop, Claude Code (CLI), or any other MCP-compatible client
• Internet access (all data is fetched at runtime)

Quick install (recommended) — no clone, no manual setup

PoeMCP is published to PyPI as poe-buildmcp, so an ephemeral runner like uvx can fetch and run it on demand — nothing to clone or keep updated. Add this to your MCP client config:

{
  "mcpServers": {
    "poemcp": {
      "command": "uvx",
      "args": ["--from", "poe-buildmcp", "poemcp"]
    }
  }
}

• Claude Desktop config location: macOS ~/Library/Application Support/Claude/claude_desktop_config.json · Windows %APPDATA%\Claude\claude_desktop_config.json
• Claude Code (CLI): add the same block to your project's .mcp.json — see mcp.json.example
• Requires uv installed (which provides uvx); no separate Python install needed, uvx manages its own interpreter.

💡 Not sure how to configure Claude? Ask Claude directly: "Add an MCP server called PoeMCP to my config, using command uvx and args [\"--from\", \"poe-buildmcp\", \"poemcp\"]." Claude will walk you through finding the config file and adding the correct JSON block for your OS.

Manual install (for development / hacking on the source)

⚠️ Python 3.10+ is required for this path. Download from python.org if you don't have it.

git clone https://github.com/shalayiding/POEMCP.git
cd POEMCP
pip install -e .

Then point your MCP config at the cloned copy instead of uvx:

macOS / Linux:

{
  "mcpServers": {
    "poemcp": {
      "command": "python",
      "args": ["/path/to/PoeMCP/server.py"]
    }
  }
}

Windows:

{
  "mcpServers": {
    "poemcp": {
      "command": "python",
      "args": ["C:\\path\\to\\PoeMCP\\server.py"]
    }
  }
}

MCP Tools Reference

search_gem

Search for Path of Exile gems by name or description keyword.

Parameters	query: str — keyword to match against gem names and descriptions
Returns	List of matching gems with name, type (active/support), tags, and short description. Fuzzy matched, up to 20 results.

---

get_gem_detail

Get detailed information about a specific gem.

Parameters	gem_name: str — e.g. "Fireball" or "Leap Slam"
Returns	Full gem stats: tags, mana cost, cast time, quality bonuses, and a per-level table showing damage, radius, and other scaling values.

---

search_item

Search for Path of Exile unique items by name, base type, or mod keyword.

Parameters	query: str — supports fuzzy matching; partial names, base types, and mod text all work
Returns	List of matching unique items with name, base type, and key mods. Up to 10 results.
Examples	"headhunter", "leather belt", "culling strike", "life leech dagger"

---

get_item_detail

Get detailed information about a specific unique item.

Parameters	item_name: str — e.g. "Headhunter" or "Lifesprig"
Returns	Full item data: base type, implicits, all explicit mods with value ranges, flavour text, acquisition methods (div cards, vendor recipes, drop sources), and links to poedb and the Community Wiki.

---

search_passive

Search for passive skill tree nodes by name or stat keyword.

Parameters	query: str — keyword to match against node names and stats
	type: str (optional) — filter by "keystone", "notable", "mastery", or "ascendancy"
Returns	List of matching nodes with name, type, and stat preview. Excludes small passives and jewel sockets unless directly matched by name. Up to 20 results.

---

get_passive_detail

Get full information about a specific passive skill tree node.

Parameters	name: str — e.g. "Iron Reflexes" or "Divine Shield"
Returns	Full node stats, mastery effects (if applicable), reminder text, flavour text, ascendancy name, and a list of connected nodes.

---

passive_tree_path

Find the shortest passive-tree path from a build's currently allocated nodes to a target node — mirrors Path of Building's own pathing algorithm, so the point cost is exact, not estimated.

Parameters	build_url: str — a pobb.in or pastebin.com URL for the build to path from
	target_node: str — name of the notable/keystone/passive to path to, e.g. "Cult-Leader"
Returns	Number of new points required (moving through already-allocated nodes is free) and the full node-by-node path. If the target has no fixed tree location, reports that it's a Cluster Jewel-only notable instead of a false "not found".

---

search_mods

Search for item modifiers (prefixes and suffixes) available on a given item type.

Parameters	item_type: str — item type to look up. Examples: "helmets str", "daggers", "amulets", "boots dex", "body armours str int", "cobalt jewel"
	query: str (optional) — keyword to filter modifiers, e.g. "life", "fire resistance", "attack speed"
Returns	Grouped list of prefixes and suffixes that can roll on that item type, with mod name, tier, item level requirement, and value ranges. Also includes corrupted implicits if present.

---

env_search

Search for maps and scarabs by name or keyword.

Parameters	query: str — keyword to match against names and descriptions
	category: str (optional) — "maps" or "scarabs" to narrow results
Returns	List of matching maps (with tier and boss) or scarabs (with effect text).

---

env_detail

Get detailed information about a specific map or scarab.

Parameters	name: str — e.g. "Strand Map" or "Breach Scarab"
Returns	Maps: tiers, boss name, tileset, area level, vaal area, connected maps, and wiki link. Scarabs: full effect text and stack size.

---

price_check

Search poe.ninja for the current price of an item or currency.

Parameters	query: str — item name to search
	league: str (optional) — league name. Defaults to current temp league (auto-detected).
	category: str (optional) — hint to narrow search: "currency", "unique", "gem", "divcard", "map", etc.
Returns	Item name, price in chaos orbs and divine orbs, number of active listings, and the league queried. Results are cached for 15 minutes.

---

currency_overview

Get the top currency exchange rates from poe.ninja.

Parameters	league: str (optional) — defaults to current temp league
Returns	Top 20 currency items ranked by chaos value, showing chaos equivalent and divine equivalent for each. Results are cached for 15 minutes.

---

fetch_wiki_page

Fetch and extract readable content from a poewiki.net page.

Parameters	wiki_url: str — full poewiki.net URL, e.g. "https://www.poewiki.net/wiki/Headhunter"
Returns	Cleaned page content with navigation and noise stripped, preserving the main article text, mechanics sections, and acquisition info. Useful for deep dives on mechanics not covered by other tools.

---

parse_pob

Parse a Path of Building share URL into a full build summary.

Parameters	url: str — a pobb.in URL or a Pastebin URL. Raw pasted export codes aren't accepted — they're thousands of characters long and reliably get corrupted in transit through chat/text input; export to pobb.in or Pastebin and share the link instead.
Returns	Full build summary including:
	• Class, ascendancy, level
	• Build notes (author's written guide, color codes stripped)
	• Progression stages — each gear/skill/tree loadout with stage title and node count, so you can follow a build guide step by step
	• Bandit choice and Pantheon gods
	• Build Warnings — auto-flagged issues computed from PoB's own numbers: uncapped resistances, negative chaos resistance, the build's weakest damage type relative to the others, no chance-based mitigation layer, self-inflicted degen exceeding regen, unmet attribute requirements
	• Key stats (Life, ES, Armour, Evasion, DPS, Hit Chance, etc.)
	• Effective Hit Pool per damage type, Sustain (regen/degen/leech), and a DPS breakdown (culling, bleed, ignite, poison, DoT) — all read directly from PoB's own computed PlayerStat values, not recalculated
	• All skill links grouped by slot
	• Every equipped item with full mod list (implicits + explicits, crafted mods labelled)
	• Allocated keystones and notable passives from the passive tree
