How to Use the MongoDB Atlas Vector Search MCP in CrewAI

Q: Can my CrewAI agents perform similarity searches using MongoDB Atlas Vector Search?

Yes, pass the search tool to your agents. They will use it to find relevant vectors during their autonomous execution cycles.

Q: Can I filter search results when using MongoDB Atlas Vector Search in CrewAI?

Use the find tool to scope your queries. Your agents can then parse the filtered data to make more accurate decisions.

Deploy specialized agent crews to manage your vector database with MongoDB Atlas Vector Search tools.

Collaborative vector search for CrewAI agents

Assign a researcher agent to run `search` and a moderator agent to review the results. By distributing these tasks, your crew handles complex data retrieval without bottlenecks. It allows for role-based interactions with your database. One agent handles the heavy lifting of querying, while another validates the output before your system makes a decision.

Audit collection health within CrewAI

Use `list_collections` to give your monitor agents visibility into your database state. If a collection grows too large, the agent can signal a need for maintenance. This keeps your operations proactive. Your agents watch the database and report back, ensuring your storage remains organized and performant.

Autonomous document lifecycle in CrewAI

Set your agents to use `delete` and `insert` as part of a cleanup crew. They can prune stale documents and add new ones based on your ongoing research tasks. It creates a self-maintaining database loop. Your crew keeps the vector store accurate, removing the need for manual intervention by your engineering team.

Setup guide

Set up MongoDB Atlas Vector Search 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 MongoDB Atlas Vector Search tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent MongoDB Atlas Vector Search 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="MongoDB Atlas Vector Search Analyst",
        goal="Access and analyze MongoDB Atlas Vector Search data via MCP.",
        backstory="Expert analyst with direct MongoDB Atlas Vector Search access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent MongoDB Atlas Vector Search transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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