+## MCP Integration
+
+This skill leverages MCP servers for enhanced brainstorming:
+
+### Sequential Thinking (Primary)
+```
+Use Sequential Thinking for structured exploration:
+- Track design options as thought sequences
+- Build confidence in recommendations incrementally
+- Allow for revisions as user provides feedback
+- Document reasoning chain for design decisions
+```
+
+### Memory
+```
+Persist design decisions across sessions:
+- Store design concepts as entities
+- Create relations between components
+- Recall user preferences from previous sessions
+- Build project design knowledge over time
+```
+
+### Context7
+```
+For informed technology choices:
+- Fetch current library documentation
+- Compare capabilities accurately
+- Ground recommendations in real data
+```

+## MCP Integration
+
+This skill is powered by the Sequential Thinking MCP server:
+
+### Using the MCP Tool
+```
+The Sequential Thinking MCP server provides the `sequentialthinking` tool.
+Use it for:
+- Breaking complex problems into thought sequences
+- Tracking confidence and revising conclusions
+- Building evidence chains with explicit reasoning
+- Maintaining state across multiple reasoning steps
+```
+
+### Tool Parameters
+```
+thought: Your current thinking step
+thoughtNumber: Current step number
+totalThoughts: Estimated total steps needed
+nextThoughtNeeded: Whether more steps are needed
+isRevision: If revising previous thinking
+needsMoreThoughts: If more analysis needed
+```
+
+### Integration Pattern
+```
+1. Start with initial thought defining the question
+2. Gather evidence in subsequent thoughts
+3. Form hypotheses with probability estimates
+4. Test and verify in later thoughts
+5. Conclude with confidence score
+```
