What is the Fireblocks MCP Server?
Connect your Fireblocks workspace to any AI agent to orchestrate institutional-grade digital asset operations through natural language conversation.
What you can do
- Vault Management — List, create, and inspect vault accounts and asset balances across your entire organization.
- Transaction Orchestration — Create, estimate fees, and monitor transactions across multiple blockchains with full lifecycle control.
- Wallet Connectivity — Manage internal and external wallets, and generate new deposit addresses for various assets.
- Advanced Asset Support — Interact with NFTs, staking positions, and smart contracts directly from the console.
- Compliance & Security — Validate travel rules, manage gas station settings, and retrieve screening information for transactions.
How it works
- Subscribe to this server
- Enter your Fireblocks API Key and Private Key
- Start managing your digital asset infrastructure from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Treasury Managers — instantly check balances across hundreds of vaults and initiate transfers without manual dashboard navigation.
- DevOps Engineers — automate the creation of vault accounts and deposit addresses during deployment workflows.
- Compliance Officers — quickly retrieve screening results and validate travel rule data for specific transactions.

Why CrewAI?
When paired with CrewAI, Fireblocks becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Fireblocks 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
Fireblocks in CrewAI
Fireblocks and 4,000+ other MCP servers. One platform. One governance layer.
Teams that connect Fireblocks 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 Fireblocks in CrewAI
The Fireblocks 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 40 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
Fireblocks for CrewAI
Every tool call from CrewAI to the Fireblocks MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I check the balance of a specific asset in a vault account?
Yes. Use the get_vault_account_asset tool by providing the Vault Account ID and the Asset ID. The agent will return the available, total, and pending balances.
How do I estimate transaction fees before sending funds?
You can use the estimate_fee tool. Provide the transaction details, and the agent will return the estimated network fees for different priority levels.
Is it possible to list all supported blockchains in my workspace?
Yes, the list_blockchains tool retrieves a comprehensive list of all blockchain networks currently supported and configured in your Fireblocks environment.
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.
