Overwatch 2 Data MCP Server

Overwatch 2 Data MCP Server & Agent Skill — Hero Meta, Player Stats, Replays, Patch Notes & OWCS Korea

English | 한국어

Query Overwatch 2 hero meta, public player stats, evidenced rankers, replay codes, official patch notes, and OWCS Korea data from an MCP client or a standalone agent skill. Both interfaces share ten read-only query operations and one SQLite store, with source URLs, observation dates, applied filters, cache state, and warnings preserved in every result.

Use it to compare heroes by region and rank, inspect public BattleTag profiles, retrieve curated ranker/replay evidence, connect patch changes to the available data period, and keep ranked statistics separate from esports metrics. Data is fetched only when requested; there is no scheduled collector, game-client automation, or private-profile access.

Built with Python 3.11+ and uv. Choose the skill, MCP server, or both.

The legacy v0.3.1 MCPB keeps its original Overwatch AIO MCP display

label. Version 0.3.2 and later use the Overwatch 2 Data MCP Server label.

Published release assets remain immutable.

The skill runs its CLI independently. MCP does not require a skill installation. There is no automatic switching or duplicate execution.

Install the skill

Use the skills CLI for a project installation:

npx skills add BK927/overwatch-aio --skill overwatch-aio-skill --agent codex

Add --global for a personal installation. Python and uv are needed for queries; Node.js is only needed for this installer. Use the skill directory reported by the installer.

Alternatively, ask Codex's Skill Installer:

Install the skill at the root of BK927/overwatch-aio as overwatch-aio-skill. Use the specified commit if I provide one.

For a pinned installation, use its script with your local Codex skills path:

python <Codex skills>/.system/skill-installer/scripts/install-skill-from-github.py --repo BK927/overwatch-aio --path . --name overwatch-aio-skill --ref <commit-SHA>
uv sync --frozen --no-dev --project "<installed-skill-directory>"

The Skill Installer's default personal directory is ~/.codex/skills/overwatch-aio-skill. Invoke $overwatch-aio-skill or ask an Overwatch data question. Your database, caches, and development environment are not distributed.

Example requests:

• “Compare Reinhardt and Ramattra in Asia Master, with sources and the actual data period.”
• “Show Korea-specific data if available, and distinguish it from Asia data.”
• “Find Reinhardt replays linked to evidenced Korean players and show their playback verification.”
• “Explain Reinhardt's latest patch changes alongside OWCS Korea data.”

Install the MCP server

MCPB-compatible clients supporting the UV runtime (manifest 0.4) can install the .mcpb file from a GitHub release. Dependencies are prepared at first launch. The source installation below works with clients using ordinary stdio or Streamable HTTP configuration.

Clone the repository or use an installed skill directory. Replace with its absolute path:

git clone https://github.com/BK927/overwatch-aio.git
uv sync --frozen --no-dev --extra mcp --project "<project-directory>"
uv run --frozen --no-dev --extra mcp --project "<project-directory>" overwatch-aio-mcp serve
