10.4 Troubleshooting
Section titled “10.4 Troubleshooting”Interactive Troubleshooting: Use the
/diagnosecommand for guided, interactive problem-solving. It auto-scans your environment and provides targeted solutions. See examples/commands/diagnose.md.
Quick Diagnostic Guide
Section titled “Quick Diagnostic Guide”Use this symptom-based guide for rapid issue identification and resolution:
| Symptom | Likely Cause | Quick Fix | Prevention |
|---|---|---|---|
| ”Context too long” error | Session accumulated too much context | /compact first, then /clear if needed | Compact regularly at 70% |
| Slow/delayed responses | High context usage (>75%) | Check /status, run /compact | Monitor context with /status |
| ”Rate limit exceeded” | API throttling from frequent requests | Wait 2 minutes, use --model haiku for simple tasks, or use cc-copilot-bridge for flat-rate access | Batch operations, use /compact, consider Copilot Pro |
| Claude forgets instructions | Context overflow, CLAUDE.md lost | Create checkpoint, /clear, reload CLAUDE.md | Keep CLAUDE.md concise (<500 lines) |
| MCP server not connecting | Server crashed or config error | claude mcp list, check paths, restart server | Test servers after config changes |
| Permission prompts every time | Tool not in allowedTools | Add pattern to settings.json allowedTools | Use wildcards: Bash(git *) |
| Changes not taking effect | Cached configuration | Restart Claude Code session | Use /exit before config changes |
| Session won’t resume | Corrupted session file | Start fresh with /clear | Exit cleanly with /exit or Ctrl+D |
Quick Diagnosis Flow:
- Check context:
/status→ If >70%, run/compact - Check connectivity: Try simple command → If fails, check network
- Check configuration:
claude mcp list→ Verify MCP servers - Check permissions: Review error message → Add to allowedTools if needed
- Still failing:
/doctor→ Run diagnostics and verify system health
Common Issues Reference
Section titled “Common Issues Reference”| Symptom | Cause | Solution |
|---|---|---|
| ”Context too long” | Used 100% context | /clear or /compact |
| Slow responses | High context usage | /compact |
| ”Permission denied” | Security settings | Check settings.local.json |
| Hook not running | Registration error | Check settings.json matcher |
| MCP tool not found | Server not running | Check mcp.json config |
| Agent not found | File naming | Check .claude/agents/ |
| Command not found | Path error | Check .claude/commands/ |
Context Recovery
Section titled “Context Recovery”| Context Level | Recommended Action |
|---|---|
| 0-50% | Continue normally |
| 50-75% | Be more specific in queries |
| 75-90% | Use /compact |
| 90%+ | Use /clear |
Common Errors
Section titled “Common Errors”“Tool execution failed”
- Check tool permissions in
settings.local.json - Verify command syntax
- Check for missing dependencies
“Agent not available”
- Verify agent file exists in
.claude/agents/ - Check YAML frontmatter syntax
- Restart Claude Code session
“Hook blocked operation”
- Check hook exit code (2 = blocked)
- Review hook error message
- Adjust hook rules if needed
MCP Server Issues
Section titled “MCP Server Issues”Common MCP Errors and Solutions
Error 1: Tool Name Validation Failed
Section titled “Error 1: Tool Name Validation Failed”API Error 400: "tools.11.custom.name: String should match pattern '^[a-zA-Z0-9_-]{1,64}'"Cause: MCP server name contains invalid characters.
Solution:
- Server names must only contain: letters, numbers, underscores, hyphens
- Maximum 64 characters
- No special characters or spaces
Example:
# ❌ Wrongclaude mcp add my-server@v1 -- npx server
# ✅ Correctclaude mcp add my-server-v1 -- npx serverError 2: MCP Server Not Found
Section titled “Error 2: MCP Server Not Found”MCP server 'my-server' not foundCause: Server not properly registered or wrong scope.
Solution:
- Check scope settings (local/user/project)
Terminal window claude mcp list # Verify server is listed - Ensure you’re in the correct directory for local scope
- Restart Claude Code session
- Re-add server if needed:
Terminal window claude mcp add my-server -s user -- npx @my/server
Error 3: Windows Path Issues
Section titled “Error 3: Windows Path Issues”Error: Cannot find module 'C:UsersusernameDocuments'Cause: Backslashes in Windows paths not properly escaped.
Solution:
# ❌ Wrongclaude mcp add fs -- npx -y @modelcontextprotocol/server-filesystem C:\Users\username\Documents
# ✅ Correct - Use forward slashesclaude mcp add fs -- npx -y @modelcontextprotocol/server-filesystem C:/Users/username/Documents
# ✅ Correct - Escape backslashesclaude mcp add fs -- npx -y @modelcontextprotocol/server-filesystem "C:\\Users\\username\\Documents"MCP Debugging Techniques

| Error | Cause | Solution |
|---|---|---|
ECONNREFUSED | Server not running | Check mcp.json command is correct |
Timeout after 30s | Slow initialization | Increase timeout or check server logs |
Module not found | Missing dependencies | Run npm install in server directory |
Permission denied | File access | Check file permissions on server executable |
ENOENT | Server binary not found | Verify npx/npm is in PATH |
Invalid JSON | Server output malformed | Check server version compatibility |
Serena MCP specific issues:
# Index not foundserena list-memories# If empty, re-index:# In your project, ask Claude: "Index this project with Serena"
# Session not persisting# Check mcp.json has correct data directory:{ "mcpServers": { "serena": { "command": "npx", "args": ["-y", "@serenaai/serena-mcp"], "env": { "SERENA_DATA_DIR": "/absolute/path/to/.serena" } } }}Context7 MCP issues:
# Documentation not found# Ensure you're searching for official libraries:# ✅ "React useState documentation"# ❌ "my-custom-lib documentation" (not in Context7)
# Slow lookups# Context7 fetches from official docs - network dependent# Check your internet connectionSequential Thinking MCP issues:
# "Sequential not responding"# Sequential uses significant compute - expect 10-30s responses# Not an error, just be patient
# Quality seems off# Sequential works best with specific, well-defined problems# ✅ "Debug why user authentication fails on mobile"# ❌ "Make the app better"Permission Issues
Section titled “Permission Issues”Pattern matching problems:
// ❌ Wrong - too specific{ "allowedTools": ["Bash(npm test)"]}// This ONLY allows exactly "npm test"
// ✅ Right - use wildcards{ "allowedTools": ["Bash(npm *)"]}// This allows any npm commandCommon permission patterns:
{ "allowedTools": [ "Bash(git *)", // All git commands "Bash(npm *)", // All npm commands "Bash(pytest *)", // All pytest commands "Edit", // All file edits "Write", // All file writes "Read", // All file reads "mcp__serena__*", // All Serena tools "mcp__context7__*", // All Context7 tools "Task" // Allow agent delegation ]}Timeout Issues
Section titled “Timeout Issues”Claude stops responding mid-task:
Possible causes:
- Network interruption - Check your internet connection
- API rate limit - Wait 1-2 minutes and retry
- Context exhausted - Use
/compactor/clear - Long-running operation - Some MCP operations take 30s+
Workaround for long operations:
# Instead of:"Analyze all 500 files in the codebase"
# Break into chunks:"Analyze files in /src/components/ first""Now analyze /src/utils/""Finally analyze /src/services/"Installation Issues
Section titled “Installation Issues”Windows-specific problems:
# npm global install fails# Run PowerShell as Administratornpm install -g @anthropic-ai/claude-code
# PATH not updated# Manually add to PATH:$env:Path += ";$env:APPDATA\npm"
# Permission errors# Check antivirus isn't blocking Node.jsmacOS-specific problems:
