# MCP: Coordination

## When This Skill Applies
- Complex tasks requiring multiple MCP servers
- Server selection decisions for optimal tool matching
- Multi-server coordination (parallel or sequential)
- Fallback strategy when servers are unavailable

## Core Guidance

**Server Selection** (see `${CLAUDE_SKILL_DIR}/references/server-selection.md`):
| Server | Primary Use | Activation Signals |
|--------|------------|-------------------|
| Context7 | Library docs, framework patterns | import/require, framework keywords |
| Playwright | E2E testing, performance metrics | test/e2e, browser interaction |
| Sequential | Complex multi-step analysis | debug/trace, system design, --think |
| Magic | UI component generation | component/button/form, JSX patterns |

**Auto-Activation Rules**:
| Pattern | Servers |
|---------|---------|
| External library code | Context7 |
| UI component work | Magic + Context7 |
| E2E test creation | Playwright + Sequential |
| Complex debugging | Sequential + Context7 |
| Full system analysis | All servers |

**Coordination Modes**:
- **Parallel**: Independent aspects of same task (Context7 docs + Playwright testing)
- **Sequential**: Output feeds next (Context7 patterns -> Magic generate -> Playwright test)

**Fallback Strategies** (see `${CLAUDE_SKILL_DIR}/references/fallback-strategies.md`):
| Server Down | Fallback |
|-------------|----------|
| Context7 | WebSearch for documentation |
| Sequential | Native extended thinking |
| Magic | Manual component from Context7 patterns |
| Playwright | Generate test code for local execution |

**Anti-Patterns**: All servers for simple tasks, ignoring failures without fallback, sequential when parallel works, repeating identical queries

## Quick Reference
- Server selection: `${CLAUDE_SKILL_DIR}/references/server-selection.md`
- Fallback strategies: `${CLAUDE_SKILL_DIR}/references/fallback-strategies.md`
- Activate only servers scoring >0.6 relevance
- Cache Context7 lookups (2-5K tokens saved per query)

## Rationalizations

The following table captures common excuses agents make to skip the rigor of this skill, paired with factual rebuttals.

| Excuse | Rebuttal |
|--------|----------|
| "one MCP server is enough" | specialized servers outperform generalists — coordinate them, do not collapse them |
| "parallel MCP calls cause chaos" | parallel calls are the whole point of coordination — chaos comes from missing fallback strategy |
| "I will sequence everything" | sequential blocks on the slowest call — parallelize independent work |
| "fallback is YAGNI" | MCP servers fail, timeout, and rate-limit — fallback is the difference between degraded and down |
| "orchestration logic belongs in the agent prompt" | prompts drift; orchestration logic belongs in the coordination skill with explicit modes |
