Compatible with every major AI agent and IDE
What is the Superblocks MCP Server?
Connect your Superblocks organization to any AI agent to streamline the management of your internal applications and automated workflows. This server allows you to orchestrate your low-code ecosystem through natural language.
What you can do
- Application Management — List all organizational applications, fetch detailed configurations, and create or update apps programmatically.
- Workflow Orchestration — Retrieve a comprehensive list of all active workflows to monitor your backend logic and scheduled jobs.
- Secure Embedding — Generate authenticated session tokens for Embedded Apps, enabling seamless SSO integration for your end-users.
- Lifecycle Control — Perform maintenance by updating application payloads or deleting obsolete resources directly from your chat interface.
How it works
- Subscribe to this server
- Enter your Superblocks API Key
- Start managing your internal tooling infrastructure from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Internal Tools Engineers — quickly audit application configurations and manage resource lifecycles without leaving the terminal or IDE.
- DevOps Teams — monitor active workflows and automate the deployment or update of Superblocks applications.
- Product Managers — list available internal tools and generate embed tokens for stakeholder reviews or client integrations.

Why CrewAI?
When paired with CrewAI, Superblocks becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Superblocks 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
Superblocks in CrewAI
Superblocks and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Superblocks to CrewAI through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for Superblocks in CrewAI
The Superblocks MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 7 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in CrewAI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
Superblocks for CrewAI
Every tool call from CrewAI to the Superblocks MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How can I see all the internal tools currently built in my organization?
You can use the list_applications tool. It retrieves a paginated list of all Superblocks applications, allowing your AI to browse through your entire internal tool library.
Is it possible to generate a login token for a user to view an embedded app?
Yes, the create_embed_token tool is designed specifically for this. Provide the user's email and optional metadata to receive a secure session token for Embedded Apps.
Can I check the status of my backend workflows and scheduled jobs?
Absolutely. Use the list_workflows tool to get a full inventory of all workflows in your organization, which helps in monitoring your automated processes.
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.
