🎯 Usage Examples

Example 1: Enable MCP 2025-11 Features

bash
# Start MCP server with 2025-11 features
npx claude-flow mcp start --mcp2025

# Check status
npx claude-flow mcp status
# Output: MCP 2025-11: enabled

Example 2: Use Progressive Disclosure

bash
# Tools are now loaded on-demand automatically
# Initial listing shows only names (2k tokens vs 150k)

# Use tools/search for discovery
npx claude-flow mcp call tools/search '{"query": "memory", "detailLevel": "basic"}'

# Tools load automatically on first invocation
npx claude-flow mcp call memory_store '{"key": "test", "value": "data"}'

Example 3: Verify AgentDB Integration

bash
# Check memory stats with ReasoningBank
npx claude-flow memory stats

# Expected output:
# πŸ“Š Memory Statistics
# Backend: SQLite (.swarm/memory.db)
# Total memories: 19
# Average confidence: 80%
# Database size: 11.92 MB

Example 4: Test Async Job Management (MCP 2025-11)

javascript
// Submit async job
const job = await mcp.call('tools/long_running_task', { data: '...' });
// Returns: { job_id: 'abc-123', request_id: 'req-456' }

// Poll for status
const status = await mcp.call('jobs/status', { job_id: 'abc-123' });
// Returns: { status: 'running', progress: 45 }

// Resume completed job
const result = await mcp.call('jobs/resume', { job_id: 'abc-123' });
