Häufige Setup-Fehler

Fehler 1: Token nicht gesetzt

Problem: GITHUB_TOKEN not found

Lösung:

export GITHUB_TOKEN=ghp_xxxxxxxxxxxx
# Dann in settings.json referenzieren: ${GITHUB_TOKEN}

Fehler 2: Service nicht erreichbar

Problem: Connection refused on localhost:5432

Lösung:

# Checke ob Service läuft
postgres: pg_isready
docker: docker ps
kubernetes: kubectl get pods

Fehler 3: Permissions Error

Problem: Permission denied reading /home/user/file

Lösung:

chmod u+r /path/to/file
# oder MCP Server mit sudo starten
sudo claude mcp add ...

Performance: Zu viele MCP Server?

Problem: Wenn du 20+ MCP Servers hast, wird Claude langsam (jeder Server wird geladen).

Lösung: Nutze mcp2cli um nur benötigte Tools zu exposen.

mcp2cli convert openapi \
  https://api.github.com/openapi.json \
  --tools "repos,issues" \
  --output github-filtered.json
