CrewAI agents for design auditing

Assign a design agent to run `check_color_contrast` across your site's component library. The agent reports back on every failed ratio it finds. This lets your crew focus on fixing accessibility issues rather than just finding them. It scales your design QA efforts without extra human labor.

Specialized accessibility monitoring

Let a monitor agent use `check_dark_mode_surface` to keep your theme consistent. It continuously checks for regressions in your visual hierarchy. Your crew stays vigilant while you work on other tasks. If the contrast drops below the WCAG limit, the agent notes the specific component.

Automated design verification

Use `check_black_text_on_bg` and `check_white_text_on_bg` as part of your agent's research phase. It validates that all new assets comply with your accessibility policy. This adds a layer of objective measurement to your design process. Your crew acts based on hard data from the server.

Setup guide

Set up Color Contrast Checker MCP in CrewAI

Prerequisites

Python 3.10+ installed
crewai package (pip install crewai)
Active Vinkius subscription with a valid endpoint token

1

Install CrewAI
Run pip install crewai to install the framework. MCP support is built-in via the mcps parameter.
2

Add the MCP URL to your agent
Pass your Vinkius endpoint directly to the mcps list. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. CrewAI handles tool discovery and caching automatically.
3

Kick off your crew
Create a Crew with your agent and tasks. Call crew.kickoff() — the agent will automatically invoke Color Contrast Checker tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="Color Contrast Checker Analyst",
    goal="Access and analyze Color Contrast Checker data via MCP.",
    backstory="Expert analyst with direct Color Contrast Checker access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent Color Contrast Checker transactions",
    agent=agent,
    expected_output="A summary of recent activity",
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()
print(result)

Prerequisites

Python 3.10+ installed
crewai + crewai-tools packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install crewai crewai-tools. The MCPServerAdapter handles lifecycle management and tool conversion.
2

Connect with MCPServerAdapter
Use MCPServerAdapter as a context manager with SseServerParameters pointing to your Vinkius endpoint. The adapter automatically manages connection lifecycle.
3

Assign tools and run
Pass the returned mcp_tools to your agent's tools parameter. The adapter converts MCP tools to native BaseTool objects compatible with all CrewAI agents.

crew.py

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import SseServerParameters

server_params = SseServerParameters(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

with MCPServerAdapter(server_params) as mcp_tools:
    agent = Agent(
        role="Color Contrast Checker Analyst",
        goal="Access and analyze Color Contrast Checker data via MCP.",
        backstory="Expert analyst with direct Color Contrast Checker access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Color Contrast Checker transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

    crew = Crew(agents=[agent], tasks=[task])
    result = crew.kickoff()
    print(result)
