How to Use the Doppler MCP in CrewAI

Q: Can CrewAI agents use Doppler to change secrets?

Yes, you can grant your agents the changesecrets tool. We recommend using a moderator agent to oversee these changes to ensure they follow your security protocols.

Specialized secret auditing with CrewAI

Assign a dedicated monitor agent to call `list_activity_logs` periodically. This agent can report any suspicious secret modifications back to your lead moderator agent. It allows for separation of concerns. One agent manages the keys while another keeps a watchful eye on security compliance.

Hierarchical environment control in CrewAI

Use a lead agent to call `list_configs` and define the scope for your worker agents. This ensures that no agent can access a secret they aren't authorized to use. It forces a clean structure. Your agents operate within the bounds you define, using `get_project` to ensure they are working in the right sandbox.

Autonomous secret resolution for CrewAI agents

Let your agents pull the values they need using `get_secret` during a complex task. They can fetch the necessary credentials, perform their work, and then move on without human input. It creates a self-sufficient pipeline. The agents manage their own environment state, significantly reducing the setup time for new autonomous operations.

Setup guide

Set up Doppler 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 Doppler tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Doppler MCP in CrewAI

Pass the Vinkius endpoint URL directly into your agent definition's `mcps` parameter. This gives your agents immediate access to the entire toolset for secret management.

Yes, you can grant your agents the `change_secrets` tool. We recommend using a moderator agent to oversee these changes to ensure they follow your security protocols.

Use the tool filter in the CrewAI MCP configuration to only expose specific tools like `list_secrets` while keeping `delete_secrets` off-limits for most agents.

It's built to handle high-frequency requests, making it ideal for autonomous crews. If an agent needs to check a config repeatedly, `get_config` will provide the status without adding significant latency.

All communication is encrypted, and your API token provides fine-grained control over what your agents can do. The server ensures that sensitive values like raw secret strings are only returned to the agent that requested them.
