How to Use the BuiltWith Tech Lookup MCP in CrewAI

Q: How do I pass BuiltWith Tech Lookup tools to a CrewAI agent?

Add the Vinkius HTTP endpoint to the mcps list when defining your CrewAI agent. The framework connects to the MCP Server and exposes the technology lookup tools to the agent's planning module.

Q: How does CrewAI handle credit usage limits with BuiltWith Tech Lookup?

You can restrict specific agents to the getfreedomainprofile tool using a tool filter. This prevents autonomous agents from running expensive deep scans unless authorized.

Q: How can my crew find out which domains use a specific technology?

The gettechdomainlists tool lets your research agent pull a fresh list of targets using a specific software. The agent then distributes these domains to other crew members for individual analysis.

Equip your CrewAI agent teams with BuiltWith Tech Lookup to automate deep market research.

Delegate domain analysis to specialized CrewAI agents

The `lookup_domain_tech` tool allows your research agent to inspect a prospect's software stack while your copywriter agent drafts a personalized pitch. This division of labor keeps your CrewAI execution fast and organized. This MCP Server integration gives each agent access to real-time tech stack data. The analyst agent updates the shared memory with the target's CMS, allowing the strategist agent to select the best angle.

Validate prospect trust and authority autonomously

The `get_domain_trust` tool helps your risk assessment agent verify the security profile of inbound leads. Your CrewAI crew runs this check automatically before handing off the lead to your sales execution agent. By checking trust indicators first, you stop spam domains from entering your CRM. The agent flags suspicious websites based on real trust signals rather than simple guesses.

Gather keyword intelligence for competitive analysis

The `get_domain_keywords` tool retrieves keyword profiles for any domain to feed your SEO agent. Your crew compares these keyword sets against your own content strategy to find gaps. This autonomous execution loop runs without human intervention, pulling keyword data and organizing it into markdown reports that your team can review at the end of the day.

Setup guide

Set up BuiltWith Tech Lookup 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 BuiltWith Tech Lookup tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent BuiltWith Tech Lookup 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.

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="BuiltWith Tech Lookup Analyst",
        goal="Access and analyze BuiltWith Tech Lookup data via MCP.",
        backstory="Expert analyst with direct BuiltWith Tech Lookup access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent BuiltWith Tech Lookup transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

Common questions about BuiltWith Tech Lookup MCP in CrewAI

Add the Vinkius HTTP endpoint to the `mcps` list when defining your CrewAI agent. The framework connects to the MCP Server and exposes the technology lookup tools to the agent's planning module.

Yes. Once the MCP Server is declared in your crew configuration, any agent with tool access can run lookups like `get_domain_company_info` to enrich their tasks.

You can restrict specific agents to the `get_free_domain_profile` tool using a tool filter. This prevents autonomous agents from running expensive deep scans unless authorized.

The `get_tech_domain_lists` tool lets your research agent pull a fresh list of targets using a specific software. The agent then distributes these domains to other crew members for individual analysis.

Vinkius routes all technology lookup traffic through a zero-knowledge proxy. This MCP setup processes your crew's target list and technology queries in memory and never logs them, preventing leaks of your competitor research lists.
