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.
Overwatch 2 MCP for hero meta, public player stats, replays, patch notes, and OWCS Korea.
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
v0.3.1MCPB keeps its originalOverwatch AIO MCPdisplay label. Version0.3.2and later use theOverwatch 2 Data MCP Serverlabel. 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.
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:
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 <project-directory> 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
The default transport is stdio. Use the MCP JSON example or Codex TOML example. Codex also accepts:
codex mcp add overwatch-aio -- uv run --frozen --no-dev --extra mcp --project "<project-directory>" overwatch-aio-mcp serve
For Streamable HTTP, start the server and connect to http://127.0.0.1:8765/mcp:
uv run --frozen --no-dev --extra mcp --project "<project-directory>" overwatch-aio-mcp serve --transport streamable-http
--host and --port change the listen address. The default is local-only 127.0.0.1:8765. The server has no built-in authentication; public hosting requires separate authentication and TLS. See the official Codex MCP guide for client configuration.
Keep --extra mcp in MCP launch commands and in uv sync commands for environments used by MCP. A plain uv sync can remove optional dependencies. The skill command stays unchanged.
Remote and home-server operation is only an operator deployment pattern—not a built-in hosted service. Binding to a non-loopback address is unsafe unless requests first pass through operator-controlled authentication and TLS and the database is stored durably.
Both interfaces publish the same input/output schemas. MCP returns the result as structuredContent and JSON text. Only status=error sets isError=true; empty, stale, and partial results retain their quality status and warnings. overwatch-aio-mcp schema exports the contracts. Use the local curation CLI for evidence writes.
uv run --frozen --no-dev --project "<skill-directory>" overwatch-aio-skill query ow_status
uv run --frozen --no-dev --project "<skill-directory>" overwatch-aio-skill query ow_meta --input-file "<filters.json>"
uv run --frozen --no-dev --project "<skill-directory>" overwatch-aio-skill schema
Example filters.json:
{"heroes":["reinhardt","ramattra"],"region":"ASIA","tier":"MASTER"}
Omitting the file supplies {}; --input-file - reads stdin. UTF-8 and UTF-8 BOM are supported. Stdout contains one JSON object; diagnostics go to stderr. Exit codes are 0 for ok/empty/stale/partial, 1 for execution failure, and 2 for invalid input. Inspect status and warnings. The query guide provides more examples in Korean.
DB selection is --db → OW_DB_PATH → ~/.overwatch-aio-skill/overwatch.db. The default is shared by processes running as the same user, independently of installation directories. Use absolute paths for existing records. Place --db after the executable name, before query or serve.
Existing caches, meta observations, players, replays, and manual evidence remain readable. SQLite WAL and transactions support concurrent skill writes and MCP reads. The old collection_jobs table is preserved but unused. There is no automatic database move or deletion. History contains observations made on request; unobserved periods are not backfilled. Cached responses do not create new observations. Replay recheck flags from invalidation notices update when patches are queried. HTTP cache retention is bounded to 256 entries, 64 MiB, and seven days.
The repository is BK927/overwatch-aio; the Python distribution and skill remain overwatch-aio-skill. Existing skill commands work unchanged. Older MCP users can keep overwatch-aio-mcp serve after updating their path and adding --extra mcp. Point --db at the old data/overwatch.db explicitly if needed.
ASIA mean the Korean server?No. ASIA is a provider region label, not proof of a Korean match server. OWTICS KOREA is also a provider grouping; results keep those labels distinct from evidenced player identity.
No. ow_rankers_search searches the locally curated registry and returns its recorded evidence. It does not claim complete, live Top 500 coverage.
No. A public code alone does not prove current playability. Playback state is reported only when an operator has registered evidence; this project does not launch or control Overwatch 2.
There is no scheduler. Refreshing queries contact their public sources on demand. Stored observations, curated evidence, and compatible cached/status queries remain available according to each operation's offline behavior, but cannot become fresher while offline.
It does not bypass private profiles. Public hosting is not turnkey: the current HTTP server has no built-in auth, so an operator must provide TLS, authentication, durable storage, access controls, and backups.
Sources include OverFast, Blizzard hero statistics and patch notes, OWTICS, OWReplays, and OWCS Korea releases. Requests to these services can include query filters and public player identifiers needed for the selected operation.
