How to Set Up and Use AgentSeal
AgentSeal is a tamper-evident audit logging MCP server for AI agents that records every agent action in a SHA-256 hash chain, making it cryptographically verifiable that logs have not been altered after the fact. Each logged action receives a sequence number and a hash that incorporates the previous entry, so any modification cascades detectably through the chain. Security-conscious teams deploying AI agents in production can use AgentSeal to maintain compliance audit trails, demonstrate transparency, and investigate incidents by querying and verifying the action history.
Prerequisites
- An AgentSeal API key from agentseal.io
- Node.js and npx available for running the MCP server, or Python with pip for the SDK
- An MCP-compatible client such as Claude Desktop or Cursor
- Network access to the AgentSeal API endpoint
Create an account and get your API key
Sign up at agentseal.io and generate an API key from your account dashboard. This key authenticates your MCP server with the AgentSeal audit service.
Configure Claude Desktop with npx
Add the agentseal-mcp server to your Claude Desktop configuration, passing your API key as the AGENTSEAL_API_KEY environment variable.
{
"mcpServers": {
"agentseal": {
"command": "npx",
"args": ["-y", "agentseal-mcp"],
"env": {
"AGENTSEAL_API_KEY": "your-api-key-from-agentseal.io"
}
}
}
}Restart Claude Desktop
Fully quit and relaunch Claude Desktop so the agentseal-mcp server is started and the three audit tools become available.
Optional: set a custom API endpoint
If you are using a private or self-hosted AgentSeal deployment, set AGENTSEAL_URL to point to your endpoint.
"AGENTSEAL_URL": "https://your-private-agentseal-instance.com"Verify the hash chain integrity
After logging some actions, use the verify_chain tool to confirm the cryptographic chain is intact and no records have been tampered with.
AgentSeal Examples
Client configuration
Complete Claude Desktop configuration for AgentSeal MCP with the required API key environment variable.

"mcpServers": {
"agentseal": {

"env": {
"AGENTSEAL_API_KEY": "your-api-key-from-agentseal.io"
}
}
}
}Prompts to try
Prompts that use the three AgentSeal tools: record_action, query_actions, and verify_chain.
- "Record that agent 'data-processor' performed action 'file-read' on /etc/config.json with reasoning 'required for initialization'"
- "Query the last 20 actions taken by the 'data-processor' agent"
- "Verify the integrity of the audit chain to confirm no records have been tampered with"
- "Show all actions of type 'file-write' across all agents in the last hour"
- "What was the most recent action recorded and what was its SHA-256 hash?"Troubleshooting AgentSeal
record_action returns an authentication error
Verify that AGENTSEAL_API_KEY is set correctly in the env block of your MCP client config and matches the key from your agentseal.io account. Keys are case-sensitive.
verify_chain reports hash misalignment
Hash misalignment indicates a record was altered or deleted after logging. This is the intended detection behavior — review the sequence numbers reported to identify which record in the chain broke integrity.
npx agentseal-mcp hangs or times out on startup
Check your network connection to the AgentSeal API endpoint. If using a custom AGENTSEAL_URL, confirm the URL is reachable from your machine. Try 'npx -y agentseal-mcp --version' in a terminal to isolate whether the package installs correctly.
