Autonomous research crews for CrewAI

Assign agents to query `get_bioactivity_summary` and `get_hazard_summary` independently. Your crew shares findings to build a complete toxicological profile. Agents work in parallel to speed up large-scale chemical screenings. You set the goal, and the crew handles the individual tool calls.

Specialized agents for EPA data

Create a monitor agent that uses `search_chemical_by_name` to track new compounds. A moderator agent then decides whether to run detailed `get_physicochemical_properties` checks. This role-based approach keeps your analysis focused. Each agent performs one specific task, reducing the complexity of your overall operation.

Shared memory for chemical analysis

Use the crew's shared context to store synonyms found via `get_chemical_synonyms`. Other agents use this list to search for data across multiple EPA databases. Agents collaborate by passing data through the crew's memory. This prevents redundant work and ensures every agent has the latest chemical identifiers.

Setup guide

Set up EPA Computational Toxicology 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 EPA Computational Toxicology tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent EPA Computational Toxicology 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="EPA Computational Toxicology Analyst",
        goal="Access and analyze EPA Computational Toxicology data via MCP.",
        backstory="Expert analyst with direct EPA Computational Toxicology access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent EPA Computational Toxicology transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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

Common questions about EPA Computational Toxicology MCP in CrewAI

You pass the server URL directly into your agent's MCP configuration. This allows your agents to access the full suite of EPA tools during their execution.

Absolutely. You can define a sequential process where one agent searches for chemicals and another performs the hazard assessment automatically.

Each agent in your crew can be granted specific tool access. This ensures that only the relevant agents perform the chemical data lookups.

It does. You can assign a manager agent to coordinate the work of specialized agents who query the EPA databases.

The server operates over encrypted channels. Your agents only query public EPA data, and no sensitive information is logged or stored by the server during your crew's operation.
