Spond No Match

An MCP server for managing kids' sports activities on Spond. Built for parents who want to give AI assistants access to upcoming matches, training schedules, and attendance — so you can ask "what's on this week?" or "sign Oliver up for Saturday's match" from any MCP-capable client.

Features

• Six tools — list groups, upcoming events, event details, attendance status, RSVP, and search
• Family member mapping — configure which kids belong to which groups
• Norwegian output — responses formatted in Norwegian (dates, weekdays, status labels)
• TTL caching — groups cached 1h, events 5min to minimize API calls
• Bearer token auth — optional authentication for protecting sensitive family data
• Scale-to-zero ready — lightweight Python server, works great on Knative

Tools

Tool	Description
list_groups	List all Spond groups with member counts
get_upcoming_events	Get upcoming events, filterable by kid or group
get_event_details	Full details for a specific event (location, description, RSVP)
get_attendance	Show which events are missing responses for your kids
respond_to_event	Accept or decline an event for a family member
search_events	Search upcoming events by text in title or description

Quick Start

Prerequisites

• Python 3.11+
• A Spond account with active group memberships

Run locally

# Install dependencies
pip install -r requirements.txt

# Start the server
[email protected] \
SPOND_PASSWORD=your-password \
KIDS_CONFIG='[{"name":"Oliver","groups":["Team 2013"]},{"name":"Emma","groups":["Team 2017"]}]' \
python main.py

The server starts on port 8080:

• Health check: http://localhost:8080/health
• MCP SSE endpoint: http://localhost:8080/sse

Docker

docker build -t spond-mcp .
docker run -p 8080:8080 \
  -e [email protected] \
  -e SPOND_PASSWORD=your-password \
  -e 'KIDS_CONFIG=[{"name":"Oliver","groups":["Team 2013"]}]' \
  spond-mcp

Environment Variables

Variable	Required	Default	Description
SPOND_USERNAME	Yes		Spond account email
SPOND_PASSWORD	Yes		Spond account password
KIDS_CONFIG	No	[]	JSON array mapping kid names to Spond group names
MCP_AUTH_TOKEN	No		Bearer token for authentication (see below)
PORT	No	8080	Server port
BASE_URL	No	http://localhost:8080	Public URL for SSE endpoint construction

KIDS_CONFIG Format

Maps your children's first names to their Spond group names. Group matching is fuzzy — partial matches work (e.g. "Team 2013" matches "Fjordvik Team 2013").

[
  {"name": "Oliver", "groups": ["Team 2013", "School 2014"]},
  {"name": "Emma", "groups": ["Team 2017"]}
]

Without KIDS_CONFIG, the server still works but can't filter by kid or show per-kid attendance.

Authentication

This server handles sensitive family data and supports optional bearer token authentication. When MCP_AUTH_TOKEN is set, all requests (except /health) must include an Authorization: Bearer <token> header.

• /health is always exempt (required for Knative/K8s health probes)
• When MCP_AUTH_TOKEN is empty or unset, auth is disabled (backward compatible)
• Uses constant-time comparison (hmac.compare_digest) to prevent timing attacks

# Run with auth enabled
MCP_AUTH_TOKEN=my-secret-token \
[email protected] \
SPOND_PASSWORD=your-password \
python main.py

# Test with auth
curl -H "Authorization: Bearer my-secret-token" http://localhost:8080/sse

For Kubernetes deployments, store the token as a Secret and reference it in your service manifest:

env:
- name: MCP_AUTH_TOKEN
  valueFrom:
    secretKeyRef:
      name: mcp-auth-token
      key: token

Usage with mcporter

mcporter can connect to this server as a remote MCP tool:

# List all groups
mcporter call spond.list_groups

# Get this week's events for a specific kid
mcporter call spond.get_upcoming_events kid_name=Oliver days=7

# Check what needs a response
mcporter call spond.get_attendance kid_name=Oliver

# Accept a match
mcporter call spond.respond_to_event event_id=ABC123 kid_name=Oliver accept=true

# Search for upcoming matches
mcporter call spond.search_events query=kamp days=30

For authenticated servers, configure mcporter with the Authorization header in ~/.mcporter/mcporter.json:

{
  "mcpServers": {
    "spond": {
      "url": "https://your-spond-mcp.example.com/sse",
      "transport": "sse",
      "headers": {
        "Authorization": "Bearer your-token-here"
      }
    }
  }
}

Architecture

MCP Client (mcporter, Claude, etc.)
    │ HTTP/SSE (JSON-RPC)
    ▼
spond-mcp (:8080)
    │
    └── api.spond.com (Spond API)

• Implements the Model Context Protocol over HTTP+SSE
• Uses mcp SDK with Starlette SSE transport
• Uses spond library for API access
• Stateless — all caching is in-memory with configurable TTLs

Development

# Install dev dependencies
pip install -r requirements.txt -r requirements-dev.txt

# Run tests (87 tests, including auth middleware tests)
pytest -v

# Lint
ruff check .

Homelab Deployment

This server is designed to run on Knative with scale-to-zero. See knative-service.yaml and .mise.toml for deployment tasks.

Authentication is enabled via MCP_AUTH_TOKEN from a K8s Secret (mcp-auth-token in mcp namespace).

# Build and deploy (requires mise + Docker + kubectl)
mise run full-deploy

# Integration test against deployed service (auto-fetches auth token from K8s)
mise run test:mcp
