EndzoneAPI

EndzoneAPI MCP server

The football data API. Play-by-play with EPA and win probability, player and team stats, schedules, injuries, depth charts and closing lines for every NFL game since 1999. REST API and MCP server. 500 free credits every month, no card.

You:    "What was the closing spread for every Chiefs game last season?"

Claude: [calls get_games -> one call, every game with spread, total and moneyline]

You: "Which offenses had the best EPA per play on third down in 2025?" Claude: [calls get_plays with third_down filter -> EPA already attached]

Skills

16 free Claude skills turn Claude into a football analyst wired to these tools: EPA per play and success rate, Next Gen Stats, weekly player stats, odds and devigging, prop modeling, college football and FCS, and honest backtesting. They are plain markdown folders.

git clone https://github.com/noahowsh/endzoneapi-mcp.git

Or install them as a Claude Code plugin:

/plugin marketplace add noahowsh/endzoneapi-mcp

/plugin install endzoneapi-skills@endzoneapi

Or with the skills CLI: npx skills add noahowsh/endzoneapi-mcp.

Point Claude (Claude Code, or any client that loads skills) at the skills/ folder, and connect the MCP server above so the skills can call live data. The dispatch skill routes a request to the right two or three skills. Full list: skills/README.md

You:    "Which offenses were best on third down in 2025, and how many plays is that based on?"

Claude: [loads epa-analysis + endzoneapi-tool, calls get_plays with third_down and a limit that holds the split, reports EPA per play, success rate and the play count]

Python

The official Python client is on PyPI: endzoneapi.

pip install endzoneapi

export ENDZONEAPI_API_KEY=sk_live_...

from endzoneapi import Client, to_dataframe

client = Client()

print(client.get_player_props(game_id="2025_01_KC_LAC", estimate_only=True))

props = client.get_player_props( game_id="2025_01_KC_LAC", market="player_pass_yds", bookmaker="draftkings", ) df = to_dataframe(props, key="props") print(df[["player_name", "line", "over_odds", "under_odds"]])

Quick start

This is a hosted (remote) MCP server over Streamable HTTP. There is nothing to install.

Claude Code

claude mcp add --transport http endzoneapi "https://mcp.endzoneapi.com/mcp?key=YOUR_API_KEY"

Claude Desktop, Cursor and other clients

{

"mcpServers": { "endzoneapi": { "url": "https://mcp.endzoneapi.com/mcp?key=YOUR_API_KEY" } } }

The key can also be sent as an x-api-key header or Authorization: Bearer. Connecting and listing tools works without a key; calling a tool needs one.

REST

curl -X POST https://mcp.endzoneapi.com/v1/list_teams -H "x-api-key: YOUR_API_KEY"

Every tool is POST /v1/{tool} with a JSON body.
