Collaborative research crews for FamilySearch API

Assign a researcher agent to use `search_persons` while a curator agent manages `get_person_details`. They share memory to avoid asking the same questions twice. This team-based approach allows for parallel discovery. One agent hunts for leads while the other verifies them against the official records.

Automated pedigree verification

Have a moderator agent review the output of `get_person_pedigree` for inconsistencies. If the data looks off, it forces the crew to re-run the search. This verification loop ensures your genealogical trees are accurate. The crew acts as a self-correcting system that keeps your data clean.

Memory-aware historical analysis

Let your agents pull `get_person_memories` to add context to a family tree. The crew links these stories to the correct person ID automatically. It turns raw records into a narrative. Your agents do the heavy lifting of mapping photos and stories to the right branches of the tree.

Setup guide

Set up FamilySearch API 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 FamilySearch API tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about FamilySearch API MCP in CrewAI

You pass the server URL into the agent's MCP configuration. Once set, the agents gain access to the tools and start collaborating immediately.

Yes, the agents use shared memory to track person IDs and pedigree findings. This prevents the crew from duplicating work across different tasks.

Absolutely. You can define specialized roles for your agents, where one focuses on search and the other on auditing the results.

You provide a single endpoint token during the server setup. This token covers all agents in the crew, simplifying the security overhead.

The server only grants access to records linked to your authorized credentials. Every request is isolated, and no personal data persists beyond the agent's memory.
