🚀 Quick Start

Python

from matimo import Matimo

matimo = await Matimo.init()

# List all collections in workspace
collections = await matimo.execute('bruno_list_collections', {
    'workspace_path': './collections'
})

# Get collection metadata before running
info = await matimo.execute('bruno_get_collection_info', {
    'collection_path': './collections/payment-api'
})

# Run entire collection
result = await matimo.execute('bruno_run_collection', {
    'collection_path': './collections/payment-api',
    'environment': 'staging',
    'report_path': './reports/staging-results.json'
})

# Run single request for debugging
response = await matimo.execute('bruno_run_request', {
    'collection_path': './collections/auth',
    'request_name': 'Login',
    'environment': 'staging'
})

# Bootstrap from OpenAPI spec

🔄 Agent Workflows

Autonomous Test Execution

Agent discovers spec → import_openapi → set environment → run_collection → parse results

Multi-Environment Validation

list_collections → for each environment: set_env + run_collection → compare results

Targeted Debugging

get_collection_info → run_request (single endpoint) → analyze response

Data-Driven Testing

run_collection with CSV file → multiple iterations → aggregate metrics

🔐 Authentication

Tools use environment variables for credentials. Bruno CLI manages environment setup — tools wrap CLI execution.

📖 Prerequisites

• Bruno CLI installed globally: pnpm install -g @usebruno/cli
• Python 3.11+
• Bruno collections in .bru format or OpenAPI specs

🤝 Integration

Works with:

• LangChain — Convert to StructuredTool
• CrewAI — Convert to BaseTool
• MCP — Expose via JSON-RPC to Claude / other MCP clients
• Native — Direct SDK usage
