Agent Provost: Guardrails for AI trading. An enterprise-grade Model Context Protocol (MCP) proxy for the Alpaca API. Features a hot-reloadable trading rules engine, strict rate limiting, and immutable WORM audit logging to S3 for complete compliance.
Overview
Connecting AI agents (like Claude or ChatGPT) to live trading APIs introduces massive security and compliance risks. Agent Provost solves this by acting as a secure, zero-trust Model Context Protocol (MCP) proxy specifically designed for the Alpaca trading API. It sits directly between your AI and your brokerage account, ensuring that LLMs can only execute trades within strict, pre-defined boundaries.
Built for fintech developers and algorithmic traders, Agent Provost features a hot-reloadable Rules Engine that enforces maximum trade notionals, share limits, and explicit symbol allowlists or blocklists. It includes robust rate limiting to prevent runaway AI loops and API bans.
Security is baked into the architecture. The appliance is 100% stateless, pulling ephemeral credentials into a secure RAM disk on every boot. For compliance and auditing, all AI trading requests and system actions are immutably logged to an AWS S3 bucket with Object Lock (WORM) enabled, ensuring a tamper-proof audit trail of every AI decision.
Enterprise Pricing & Private Offers: The public pricing reflects our standard on-demand rate. However, we strongly encourage enterprise customers to contact us for a Private Offer. Customers willing to commit to a multi-year agreement or participate in a logo-sharing case study are eligible for up to a 50% discount on annual licenses. Please contact support@floatingcloud.io to negotiate a Private Offer before deploying.
Highlights
- Customizable Trading Rules Engine: Enforce strict guardrails on AI agents with hot-reloadable policies. Set maximum trade notionals, share limits, and explicit symbol allowlists or blocklists to prevent rogue AI trading behavior.
- Zero-Trust Ephemeral Architecture: Designed for maximum security, the appliance is 100% stateless. API keys are never written to disk; they are fetched dynamically from AWS Secrets Manager into a secure RAM disk on every boot.
- Immutable WORM Audit Logging: Achieve enterprise-grade compliance with automatic, tamper-proof logging. Every AI request, proxy action, and system event is streamed directly to an Object Lock-enabled Amazon S3 bucket.

Agent Provost Secure Deployment
This CloudFormation template provisions the complete, zero-trust architecture required for Agent Provost. It creates a secure AWS Secrets Manager entry to hold your Alpaca API keys and trading rules, ensuring they are never written to the EC2 hard drive. It also provisions an Amazon S3 bucket with Object Lock (WORM) enabled to store your immutable trading logs. Finally, it launches the Agent Provost EC2 instance with a least-privilege IAM role, allowing it to securely fetch its configuration into a temporary RAM disk on boot.
CloudFormation Template (CFT)
AWS CloudFormation templates are JSON or YAML-formatted text files that simplify provisioning and management on AWS. The templates describe the service or application architecture you want to deploy, and AWS CloudFormation uses those templates to provision and configure the required services (such as Amazon EC2 instances or Amazon RDS DB instances). The deployed application and associated resources are called a "stack."
Version release notes
Initial release of Agent Provost. Includes the core MCP proxy, hot-reloadable Rules Engine, and immutable WORM logging to S3.
Run the cloudformation, answer the questions with deep thought. after this Fill out the ALL of the deployment parameters including the rules: Alpaca Credentials: Enter your Alpaca API Key and Secret Key (stored securely in AWS Secrets Manager, never on disk). Provost Token: Create a secure, random password. Your AI will use this to authenticate with the proxy. Trading Rules: Set your MaxTradeNotional, MaxSharesPerTrade, and your Symbol Allowlists/Blocklists. Wait for the stack status to reach CREATE_COMPLETE. Go to the Outputs tab of your CloudFormation stack to find the Public IP Address of your new appliance. Step 2: Connect Your AI (MCP Client Setup) Agent Provost acts as a remote MCP server. Update your MCP client configuration file to route traffic to your EC2 instance's IP address, using the PROVOST_TOKEN you created during deployment.
For Claude Desktop Edit your claude_desktop_config.json file:
{ "mcpServers": { "alpaca-provost": { "type": "sse", "url": "http://<YOUR_EC2_PUBLIC_IP>:8000/sse", "env": { "PROVOST_TOKEN": "<YOUR_PROVOST_TOKEN>", "PROVOST_USER": "claude-desktop", "PROVOST_MACHINE": "work-laptop" } } } } For Cursor Add this to your Cursor MCP settings (.cursor/mcp.json):
{ "mcpServers": { "alpaca-provost": { "type": "sse", "url": "http://<YOUR_EC2_PUBLIC_IP>:8000/sse", "env": { "PROVOST_TOKEN": "<YOUR_PROVOST_TOKEN>", "PROVOST_USER": "cursor-ide", "PROVOST_MACHINE": "dev-machine" } } } } (Note: Replace <YOUR_EC2_PUBLIC_IP> and <YOUR_PROVOST_TOKEN> with your actual values. The PROVOST_USER and PROVOST_MACHINE headers are optional but highly recommended, as they will be recorded in your immutable S3 audit logs to identify exactly who initiated the trade).
Step 3: Verify the Connection Restart your MCP client (Claude or Cursor). Open a new chat and type: "What is my current account balance and buying power?" Test the Rules Engine: Ask the AI to buy 10,000 shares of a stock. Agent Provost will intercept the request, block it based on your CloudFormation rules, and log the blocked attempt to your S3 bucket.
Additional details
Usage instructions
- Launch the CloudFormation stack and fill in your Alpaca API keys and trading rules.
- Wait for the stack to reach CREATE_COMPLETE.
- Connect to the EC2 instance using AWS Systems Manager (Session Manager).
- The proxy is automatically running on port 8000.
- To update your trading rules, simply update the CloudFormation stack parameters. The instance will automatically sync the new rules within 10 minutes without requiring a reboot.
