Usage Examples

Quick Scan

npm run scan -- --path ~/Sites/blueflyio

Generate All Tools

npm run generate -- \
  --path ~/Sites/blueflyio \
  --output ./generated

Generate for Service

npm run generate -- \
  --path ~/Sites/blueflyio \
  --service agent-protocol \
  --output ./generated

Programmatic Use

import { scanOpenAPISpecs, buildRegistry } from '@bluefly/mcp-generator';

const result = await scanOpenAPISpecs('/path/to/project');
const builder = await buildRegistry(result.specs, {
  outputDir: './generated',
});

await builder.exportTypeScript('./generated/registry.ts');

Output Structure

TypeScript Output

generated/
├── registry.ts              # Complete registry
├── types.ts                 # Type definitions
└── services/
    ├── agent-protocol.ts    # Per-service tools

Generated Tool Format

{
  name: 'service_operationId',
  description: 'Operation summary',
  inputSchema: {
    type: 'object',
    properties: { /* parameters */ },
    required: ['param1']
  },
  metadata: {
    serviceName: 'service',
    operationId: 'op',
    method: 'GET',
    path: '/api/resource',
    tags: ['Resources'],
    authentication: { /* auth config */ },
    sourceSpec: '/path/to/openapi.yaml'
  },
  handler: async (args) => { /* implementation */ }
}

Integration

With Agent Protocol MCP Server

import { mcpToolRegistry } from './generated/registry';

// Register all tools
for (const service of Object.values(mcpToolRegistry.services)) {
  for (const tool of service.tools) {
    mcpServer.addTool(tool);
  }
}

With Custom HTTP Client

import { MCPToolGenerator } from '@bluefly/mcp-generator';

class CustomGenerator extends MCPToolGenerator {
  protected generateHandler(spec, method, path, operation) {
    return async (args) => {
      // Your HTTP client implementation
      return fetch(url, { method, body: JSON.stringify(args.body) });
    };
  }
}
