Analyze MCP Server

審查現有MCP服務器實現，識別以下改進機會：

• Tool organization improvements
• Token efficiency optimizations
• Progressive discovery enhancements
• Better automation flag usage
• Cross-tool ID systems

Process

Step 1: Discover MCP Structure

詢問用戶MCP位置：

• Directory containing MCP server code
• Specific files to analyze
• Running MCP server endpoint (if applicable)

Use Glob and Grep to find:

• Tool definitions
• Server metadata/configuration
• Response formats
• Documentation

Step 2: Analyze Architecture

Review and assess:

Tool Organization:

• Tools grouped logically?
• Naming follows verb-noun pattern?
• Clear categories/domains?
• Tool count appropriate (not too flat)?

Token Systems:

• Uses IDs for cross-tool references?
• Avoids repeating data?
• ID format clear and consistent?

Progressive Discovery:

• Has info/help tool?
• Progressive detail levels?
• Clear next steps for users?

Response Format:

• Automation flags present?
• Human and machine readable?
• Sparse tables where appropriate?
• Standard JSON arrays for data?

Error Handling:

• Accepts extra parameters gracefully?
• Clear error messages?
• Graceful degradation?

Step 3: Generate Analysis Report

Create markdown report with:

Summary:

# MCP Analysis: [server-name]

## Overview
- Tools: X total
- Pattern: [detected pattern]
- Token efficiency: [assessment]
- Progressive discovery: [yes/no]

## Strengths
- [What's working well]

## Opportunities
- [Improvements to consider]

## Recommendations
- [Specific actionable items]

Detailed Findings:

For each category, provide:

1. Current state - What exists now
2. Assessment - Good/needs improvement
3. Recommendation - Specific changes
4. Example - Before/after if applicable
5. Impact - Token savings or UX improvement

Example finding:

### Token Efficiency

**Current:** search tool returns full code blocks (avg 250 tokens per result)

**Assessment:** ⚠️  Wasteful - repeating large code blocks

**Recommendation:** Return IDs with previews, use get_details(id) for full code

**Example:**
Before:
```json
{"results": [{"code": "... 200 lines ..."}]}

After:

{"results": [{"id": "r1", "preview": "10 lines"}]}

Impact: 80% token reduction (250 → 50 tokens per result)

### Step 4: Prioritize Recommendations

按影響力排列建議：

**High Impact (implement first):**
- ID systems for cross-tool references (70-90% token savings)
- Progressive detail by confidence (50-70% savings)
- Accept extra parameters (robustness)

**Medium Impact:**
- Info tool for discovery (better UX)
- Automation flags (AI agent friendliness)
- Tool grouping (organization)

**Low Impact (nice to have):**
- Sparse tables in info output
- Consistent naming
- Additional workflows documentation

### Step 5: Output Report

Write analysis to file:
- Default: `./mcp-analysis-{name}.md`
- Ask user for custom path if preferred
- Provide summary of findings

## Analysis Criteria

### Architecture Patterns

識別MCP使用哪種模式：
- Hub-and-Spoke
- CRUD
- Discovery-Detail
- Aggregation
- Pipeline
- Lazy Loading

評估模式是否適合用例。

### Token Efficiency Score

Calculate based on:
- Uses ID references: +40 points
- Progressive detail: +30 points
- Selective fields: +15 points
- Flattened schemas: +10 points
- Reference system for repeated values: +5 points

**Score interpretation:**
- 90-100: Excellent
- 70-89: Good
- 50-69: Needs improvement
- <50: Significant issues

### Progressive Discovery Score

- Has info tool: +30 points
- Multiple detail levels: +25 points
- Clear workflows: +20 points
- Category organization: +15 points
- Help/documentation: +10 points

**Score interpretation:**
- 80-100: Excellent discoverability
- 60-79: Good
- 40-59: Basic
- <40: Poor discoverability

## Output Format

Scores

Category	Score	Assessment
Token Efficiency	85	Good
Progressive Discovery	65	Good
Architecture	90	Excellent
Error Handling	40	Needs improvement

Top 3 Recommendations

1. Add error handling for malformed patterns (High impact)
2. Implement info tool for discovery (Medium impact)
3. Use consistent error code format (Medium impact)

Estimated Token Savings: 70-80% with ID system implementation

## Example Analyses

### Example 1: MCP with No ID System

**Finding:**
```markdown
### Token Efficiency: ⚠️  Needs Improvement (Score: 30/100)

**Issue:** All tools return complete data, no cross-tool references

**Current workflow:**
1. search("User") → Returns full User objects (500 tokens each)
2. User copies entire object to next tool
3. get_details(entire_user_object) → Redundant

**Recommendation:** Implement ID system

**Proposed workflow:**
1. search("User") → Returns [{id: "u1", name: "User", preview: "..."}]
2. get_details("u1") → Returns full details

**Impact:** 85% token reduction (500 → 75 tokens for search results)

**Implementation:**
```typescript
// Add ID generation to search tool
function search(pattern) {
  const results = performSearch(pattern)
  return results.map((r, i) => ({
    id: generateId(i),
    name: r.name,
    preview: r.code.substring(0, 100)
  }))
}

// Update get_details to accept ID
function get_details(id) {
  const full = lookupById(id)
  return full
}

### Example 2: MCP with Poor Discovery

**Finding:**
```markdown
### Progressive Discovery: ⚠️  Poor (Score: 20/100)

**Issue:** No info tool, users don't know what's available

**Current:** 15 tools, no categorization, no help system

**Recommendation:** Add info tool with categories

**Implementation:**
```typescript
function info(category?: string) {
  if (!category) {
    // Overview
    return {
      categories: [
        {name: "query", count: 3, description: "Search and find"},
        {name: "lookup", count: 5, description: "Get details"},
        {name: "management", count: 4, description: "Create/update/delete"}
      ],
      total: 12,
      next: "Use info(category='query') for tools in category"
    }
  }

  // Category detail
  return getToolsInCategory(category)
}
