How to Use the Milvus (Open-Source Vector Database) MCP in CrewAI

Q: How do CrewAI agents perform ANN searches in Milvus (Open-Source Vector Database)?

The agents invoke the searchvectors tool. They pass the embedding array, and the server returns the nearest matches directly to the agent's memory.

Q: Can CrewAI agents modify Milvus (Open-Source Vector Database) records?

Yes, they use deleteentities to remove records. You can assign this task to a moderator agent to keep your indices clean.

Q: How do I monitor Milvus (Open-Source Vector Database) health with CrewAI?

You assign a monitor agent to run getcollectionstats at set intervals. It reports the results back to your crew's shared memory.

Deploy autonomous agent crews to manage Milvus vector storage operations without human oversight.

Autonomous CrewAI Vector Search

Assign a specialized agent to execute `search_vectors` for your research tasks. It retrieves the necessary context from your vector space and passes it to the next agent in your crew. This setup allows agents to collaborate on complex similarity tasks. One agent finds the data, and another interprets the results for the final output.

Systematic Index Auditing with CrewAI

Use a monitor agent to periodically run `get_collection_stats` and `list_collections`. It keeps your crew updated on the state of your vector storage without manual intervention. If the agent detects an issue with row counts, it can escalate to a moderator agent. This creates an autonomous feedback loop for your data infrastructure.

Filtering and Retrieval for CrewAI

Configure your agents to use `query_entities` for specific scalar lookups. It allows the crew to narrow down relevant items before performing expensive ANN searches. Your agents act on the filtered data to ensure high-quality, relevant results. It reduces noise in your multi-agent collaboration.

Setup guide

Set up Milvus (Open-Source Vector Database) 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 Milvus (Open-Source Vector Database) tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent Milvus (Open-Source Vector Database) 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="Milvus (Open-Source Vector Database) Analyst",
        goal="Access and analyze Milvus (Open-Source Vector Database) data via MCP.",
        backstory="Expert analyst with direct Milvus (Open-Source Vector Database) access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Milvus (Open-Source Vector Database) transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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