How to Use the Knack MCP in CrewAI

Q: Can I limit which Knack tools a CrewAI agent can access?

Yes, you can use CrewAI's toolfilter configuration to expose only specific tools like listrecords to read-only agents, while restricting deleterecord to your supervisor agents.

Q: How do CrewAI agents handle Knack's field key format?

The agents automatically call listobjectfields to map natural language queries to Knack's internal field keys. Your CrewAI agents handle this translation in the background via the MCP, so you don't have to hardcode field mappings.

Q: Can a CrewAI team manage multiple Knack applications?

Yes. The agent can invoke listaccountapplications to discover all available applications in your account and dynamically switch contexts depending on the task assigned to the crew.

Deploy a specialized crew of CrewAI agents to monitor, audit, and update your Knack database autonomously.

Multi-agent auditing of Knack databases

The `get_record` tool allows your CrewAI auditing agent to inspect specific database entries for compliance. While one agent searches for anomalies, a second agent uses this tool to pull the complete record payload and verify its history. To find which records to audit, the research agent runs `search_records` across your application. The agents share this data through their common memory, allowing them to collaborate on cleaning up inconsistent entries.

Autonomous data entry using CrewAI agents

The `create_record` tool gives your CrewAI operations crew the ability to insert new records into Knack autonomously. A coordinator agent first calls `list_account_applications` to locate the correct target database before assigning the writing task via the MCP. Another specialized agent runs `list_object_fields` to ensure all mandatory database fields are populated correctly. This multi-agent verification prevents incomplete or malformed records from entering your production tables.

Automated schema monitoring via CrewAI

The `list_objects` tool enables your CrewAI monitoring agent to track structural changes in your database. The agent periodically pulls the object list and compares it against saved baselines to detect unauthorized modifications. If a change is detected, the agent uses `get_object_schema` to extract the exact metadata of the modified table from this MCP Server. The crew can then automatically alert your engineering team or update its own internal mapping rules.

Setup guide

Set up Knack 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 Knack tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Knack MCP in CrewAI

CrewAI agents use their shared memory to pass object keys and record IDs between each other. For example, a researcher agent might find a record using `search_records` and pass the ID to a writer agent to execute an `update_record` call.

Yes, you can use CrewAI's tool_filter configuration to expose only specific tools like `list_records` to read-only agents, while restricting `delete_record` to your supervisor agents.

The agents automatically call `list_object_fields` to map natural language queries to Knack's internal field keys. Your CrewAI agents handle this translation in the background via the MCP, so you don't have to hardcode field mappings.
