How to Use the FreeClimb MCP in CrewAI

Q: Can CrewAI agents collaborate to handle FreeClimb calls?

Yes. One agent can trigger makecall while a supervisor agent monitors the call status using getcalldetails to coordinate follow-up actions.

Q: Can I limit which FreeClimb tools a CrewAI agent can use?

Yes. You can use the MCPServerHTTP class with a toolfilter to only expose specific tools like listconferences to certain agents.

Q: Is my FreeClimb account balance safe when using CrewAI?

Yes. Your credentials and balance data accessed via getaccountstatus are restricted to your private Vinkius sandbox, ensuring autonomous agents never expose your API keys.

Multi-Agent Telephony Coordination

This MCP Server integrates `make_call` and `list_calls` into your multi-agent setups. A research agent can find target contacts, while a separate dialing agent places the calls and records the outcomes. This division of labor keeps your operations organized. Each agent focuses on a single task, passing call logs through shared memory to coordinate next steps.

Automated SMS Campaign Moderation in CrewAI

The `send_sms` and `list_sms_messages` tools allow your agent crews to execute and monitor outreach campaigns. A moderator agent reviews outbound messages before a dispatch agent executes the tool. This multi-agent review process prevents spam and carrier blocks. You ensure every outgoing SMS complies with your guidelines before it leaves the server.

Phone Inventory Optimization

With `list_buyable_numbers` and `list_my_numbers`, your provisioning agent maintains your active phone number pool. The agent automatically buys new local numbers when running localized outreach campaigns. You don't have to manually buy numbers. The crew analyzes call performance and adjusts your active number inventory dynamically.

Setup guide

Set up FreeClimb 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 FreeClimb tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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