A unified MCP server that aggregates **42 sports API providers** into a single service. **410 tools** covering scores, stats, odds, esports, college sports, chess, motorsport, boxing, AFL, and more across 70+ sports.

> Each provider works independently. You only need API keys for the providers you use. Missing keys don't block startup — tools return an error when called without their key.

**Works with:**

## Installation

### Quick (npx — no install)

```bash
npx mcp-sports-hub
```

### npm global

```bash
npm install -g mcp-sports-hub
mcp-sports-hub
```

### From source

```bash
git clone https://github.com/lacausecrypto/mcp-sports-hub.git
cd mcp-sports-hub
npm install
npm run build
```

### MCP Registry

This server is published on the [official MCP Registry](https://registry.modelcontextprotocol.io) as `io.github.lacausecrypto/sports-hub`. MCP clients that support the registry can discover and install it automatically.

## Transport Modes

### Stdio (default — Claude Desktop, Cursor, etc.)

```bash
npx mcp-sports-hub
```

### HTTP/SSE (remote clients, web apps, custom integrations)

```bash
# Via flag
npx mcp-sports-hub --http

# Via env
SPORTS_HUB_HTTP=1 SPORTS_HUB_PORT=3000 npx mcp-sports-hub
```

Endpoints:
- `POST /mcp` — MCP protocol (Streamable HTTP with SSE)
- `GET /health` — Health check (`{"status":"ok","providers":19,"sessions":0,"mode":"session"}`)

Supports CORS and multi-client session management via the `mcp-session-id` header. Default port: 3000.

Each client gets its own session, created on `initialize` and addressed afterwards by its session id. Building a session costs ~90 ms for the 165-tool `free` preset, paid once per client rather than per request. Idle sessions are reaped.

```bash
SPORTS_HUB_MAX_SESSIONS=200   # concurrent sessions before new ones get a 503
SPORTS_HUB_SESSION_TTL=1800   # seconds a session may sit idle
SPORTS_HUB_STATELESS=1        # opt out: build a throwaway server per request
```

`SPORTS_HUB_STATELESS=1` suits several replicas behind a load balancer with no sticky routing. It pays the build cost on every call, so prefer sessions for a single instance.

> **⚠ Security**: HTTP mode binds to `127.0.0.1` (loopback) by default. Setting `SPORTS_HUB_HOST=0.0.0.0` exposes an **unauthenticated** MCP endpoint to your whole network — anyone who can reach it can use your configured API keys. DNS-rebinding protection only blocks browser-origin attacks, not direct clients. Only expose it behind a reverse proxy with auth/TLS. `SPORTS_HUB_CORS_ORIGINS` must list explicit origins (a literal `*` is rejected).

### Hosted (Smithery)

A `Dockerfile` and `smithery.yaml` are included for container hosting on [Smithery](https://smithery.ai). The hosted endpoint serves the keyless `free` preset, so clients connect with zero setup. The deploy sets `SPORTS_HUB_DNS_REBINDING_PROTECTION=0` because Smithery's proxy forwards a non-localhost `Host` header.

> `SPORTS_HUB_DNS_REBINDING_PROTECTION=0` disables the Host/Origin check (it is **on** by default). Only set it when the server runs behind a trusted proxy that owns routing — never for a server directly reachable by browsers on localhost.

```

**Windows** (PowerShell):
```powershell
$env:API_SPORTS_KEY = "your-key"
$env:PANDASCORE_TOKEN = "your-token"
```

**Windows** (cmd):
```cmd
set API_SPORTS_KEY=your-key
set PANDASCORE_TOKEN=your-token
```

### Response size and the `fields` parameter

Sports APIs return very wide objects, and every byte a tool returns is spent from the model's context window. A single `espn_get_scoreboard`-style team listing is ~300 KB of JSON, of which the part anyone wants is under 3 KB.

**Every tool accepts an optional `fields` parameter**: a comma-separated list of key names to keep, matched at any depth. Branches that match nothing are dropped, and a matched key keeps its whole value.

```jsonc
// espn_get_teams { "sport": "basketball", "league": "nba" }
//   -> 297 KB

// espn_get_teams { "sport": "basketball", "league": "nba",
//                  "fields": "id,abbreviation,displayName,location" }
//   -> 2.9 KB, same 30 teams
```

If `fields` matches nothing, the tool says so and lists the top-level keys it did see, rather than returning an empty object.

Responses are also capped. Above the limit, the longest lists in the payload are shortened until it fits (so the JSON still parses) and a note reports how many items were dropped.

```bash
SPORTS_HUB_MAX_RESULT_BYTES=40000   # default; serialized bytes per tool result
```

### Claude Desktop

Config file locations:
- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
- **Linux**: `~/.config/claude/claude_desktop_config.json`

```json
{
  "mcpServers": {
    "sports-hub": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-sports-hub/dist/index.js"],
      "env": {
        "PANDASCORE_TOKEN": "your-token",
        "API_SPORTS_KEY": "your-key",
        "THE_ODDS_API_KEY": "your-key"
      }
    }
  }
}
```

Windows path: `"args": ["C:/Users/you/mcp-sports-hub/dist/index.js"]`

Only include env vars for providers you need. Omit `env` entirely for free-only providers.

### Claude Code (CLI)

```bash
claude mcp add sports-hub node /absolute/path/to/mcp-sports-hub/dist/index.js
```

Or in `.claude/settings.json`:
```json
{
  "mcpServers": {
    "sports-hub": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-sports-hub/dist/index.js"],
      "env": {
        "PANDASCORE_TOKEN": "your-token"
      }
    }
  }
}
```

## Provider Filtering

By default, only the **free preset** is loaded (19 providers, ~165 tools — no API keys needed). Use `SPORTS_HUB_PROVIDERS` to change what's loaded:

```bash
# Default — free providers only (no config needed)
npx mcp-sports-hub

# Load ALL 42 providers (410 tools)
SPORTS_HUB_PROVIDERS=all npx mcp-sports-hub

# Use a preset
SPORTS_HUB_PROVIDERS=us-major npx mcp-sports-hub

# Pick specific providers
SPORTS_HUB_PROVIDERS=espn,nhl,odds npx mcp-sports-hub

# Exclude from all (prefix with -)
SPORTS_HUB_PROVIDERS=-sportsdata,-mma npx mcp-sports-hub
```

### Presets

| Preset | Providers | Tools | Needs keys? |
|--------|-----------|-------|-------------|
| `free` (default) | 19 no-key providers (espn, nhl, mlb, f1, openf1, openliga, sportsdb, ncaa, sportsrc, lichess, chesscom, squiggle, motogp, formulae, nascar, opendota, sleeper, euroleague, footballdatauk) | ~165 | No |
| `all` | all 42 providers | 410 | Yes (for key-required providers) |
| `chess` | lichess, chesscom | 14 | No |
| `us-major` | espn, nhl, mlb, ncaa, cfbd, bdl, msf, nascar, sleeper | ~93 | Some |
| `soccer` | espn, apifootball, footballdata, sportmonks, openliga, sportsrc, footballdatauk, highlightly | ~73 | Some |
| `f1` | f1, openf1 | 25 | No |
| `motorsport` | f1, openf1, motogp, formulae, nascar | ~42 | No |
| `esports` | pandascore, opendota | 25 | Some |
| `odds` | odds, oddsio, sgo, lumify | 43 | Yes |
| `cricket` | cricket, entitycricket | 22 | Yes |
| `golf` | livegolf, golfcourse | 14 | Some |

### Cache

All GET responses are cached in memory for 60 seconds by default. This protects against duplicate calls and rate limit waste. Configure with:

```bash
SPORTS_HUB_CACHE_TTL=120  # seconds (0 to disable)
```

The cache key includes a digest of the request's auth headers, so two API keys never read each other's entries. Concurrent identical requests are collapsed into a single upstream call, and a `404`/`410` is remembered briefly (`SPORTS_HUB_NEGATIVE_CACHE_TTL`, default 30s) so a wrong ID can't be re-fetched in a loop.

### Rate limits and retries

`429` and `5xx` responses are retried with exponential backoff, honouring `Retry-After` when the upstream sends one. Client errors (`4xx` other than 408/425/429) and timeouts are not retried.

```bash
SPORTS_HUB_MAX_RETRIES=2        # extra attempts after the first (0 disables)
SPORTS_HUB_RETRY_BASE_MS=300    # backoff base; doubles per attempt
```

In Claude Desktop config:
```json
"env": {
  "SPORTS_HUB_PROVIDERS": "us-major",
  "THE_ODDS_API_KEY": "your-key"
}
```

## Tool Naming

All tools follow `{provider}_{action}`:

```
espn_get_scoreboard        — Live scores (ESPN)
nhl_get_standings          — NHL standings
mlb_get_game_boxscore      — MLB box score
f1_get_race_results        — F1 results (1950+)
openf1_get_laps            — F1 live telemetry
pandascore_get_lives       — Live esports matches
apifootball_get_fixtures   — Soccer fixtures (960+ leagues)
odds_get_odds              — Betting odds (70+ sports)
sportsrc_get_xg_stats      — Expected goals (xG)
```

## MCP Resources & Prompts

Beyond tools, the server exposes:

**Resources** (readable catalogs, no API call):
- `sportshub://providers` — the full provider catalog (prefix, name, coverage, required key)
- `sportshub://presets` — all presets and the providers they load
- `sportshub://provider/{key}` — details for one provider (with key autocompletion)

**Prompts** (curated slash-command workflows over the 410 tools):
- `whats-on-today` · `compare-odds {event}` · `motorsport-weekend {series}` · `league-standings {league}` · `team-deep-dive {team}` · `f1-race {season} {round}`

All tools are annotated `readOnly` / `idempotent` so clients can skip confirmation prompts.
