How to Use the CrossRef MCP in CrewAI

Q: How do I configure CrewAI to use the CrossRef tools?

Install crewaitools. The simplest method is adding the Vinkius endpoint directly to your agent's mcps list. The framework automatically discovers and registers the available tools.

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

Yes. Use the toolfilter parameter when setting up MCPServerHTTP. You can give one agent the DOI resolver while restricting another to author searches.

Perplexity

Assign DOI resolution to specialist agents.

Stop making one agent do all the work. You can create a dedicated Librarian agent in CrewAI and hand it the `get_crossref_doi` tool. This worker does nothing but resolve DOIs into clean, structured metadata. While the Librarian pulls abstracts and citation counts, an Analyst agent reads that shared memory. The team collaborates to build massive literature reviews. You just pass the Vinkius URL directly into the `mcps` array to get started.

Run autonomous academic sweeps.

Manual literature searches miss crucial papers. Give your CrewAI team access to `search_crossref` and tell them to find everything published about a specific protein or algorithm. The agents will query the 140-million record database iteratively. Hierarchical execution keeps the process organized. A manager agent evaluates the search results. If the bibliography looks thin, it orders the researcher agent to run broader queries until the criteria are met.

Profile researchers with the CrossRef MCP Server.

Vetting experts requires deep publication analysis. The `search_crossref_author` tool lets your agents pull a scientist's entire catalog. They get citation counts, journal names, and publication dates in one shot. Advanced setups can restrict which tools each agent sees. By using `MCPServerHTTP` from `crewai.mcp` with a `tool_filter`, you ensure your summary agent does not accidentally trigger new author searches. The operation stays tight and predictable.

Setup guide

Set up CrossRef 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 CrossRef tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about CrossRef MCP in CrewAI

Install `crewai[tools]`. The simplest method is adding the Vinkius endpoint directly to your agent's `mcps` list. The framework automatically discovers and registers the available tools.

Yes. Use the `tool_filter` parameter when setting up `MCPServerHTTP`. You can give one agent the DOI resolver while restricting another to author searches.

The framework relies on shared memory. When your researcher agent pulls bibliographic data, it writes those findings to the session context. Subsequent agents read that context to perform their tasks.

Yes. The Python implementation handles standard I/O, Server-Sent Events, and Streamable HTTP. You pick the transport that fits your deployment architecture.

Vinkius processes all queries in ephemeral, zero-trust V8 sandboxes. Your specific search terms, author names, and DOI strings exist only for the duration of the request. We never log your research focus.
