What is the Yousign MCP Server?
Connect your Yousign account to any AI agent and manage your electronic signature infrastructure through natural conversation.
What you can do
- Signature Lifecycle — Create new signature requests in draft mode, add signers, and activate requests to send them for signing
- Request Monitoring — List and browse all signature processes and retrieve real-time status (draft, ongoing, done, cancelled)
- Signer Management — Define and add multiple signers to a request by providing their contact details directly from your agent
- Document Discovery — List all files attached to a specific signature request to verify the contents before activation
- Cancellation Control — Permanently stop ongoing signature requests and provide custom reasons for termination through simple commands
- Quota Auditing — Retrieve API consumption and credit details to monitor your Yousign plan usage and remaining signatures
- Deep Discovery — Quickly find unique request, signer, and document IDs required for automated legal workflows
How it works
- Subscribe to this server
- Enter your Yousign API Key
- Start managing your signing processes through Claude, Cursor, or any MCP-compatible client
No more manual logging into the Yousign dashboard to check if a document was signed. Your AI agent becomes your legal operations assistant.
Who is this for?
- Legal & Compliance Teams — monitor signature statuses and audit document requests through simple chat commands
- HR Managers — automate signing processes for employment contracts and verify signer completion via chat
- Sales Professionals — track contract signatures and activate new signing requests without manual navigation
- Operations Managers — monitor API consumption and manage document lifecycles efficiently

Why CrewAI?
When paired with CrewAI, Yousign becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Yousign tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Frequently asked questions
Can I check the status of a signature request via chat?
Yes. The get_signature_request tool allows your AI agent to retrieve the real-time status of any request ID, showing you whether it is in 'draft', 'ongoing', 'done', or has been 'cancelled'.
How do I add signers to a draft request using the agent?
You can use the add_signer tool. Provide the unique request ID along with the signer's email, first name, and last name. You can add multiple signers to a single request before activating it.
Can I see how many signature credits I have left in my plan?
Absolutely. Use the get_api_consumption tool to retrieve your current usage statistics and remaining signature credits, helping you manage your Yousign subscription budget.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
