Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Agent Audit Trail MCP Server Log a decision event for agent abc123: 'approved loan application'"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Immutable audit logging for AI agents with hash-chained event logs, integrity verification, and EU AI Act compliance reporting.
The EU AI Act (effective August 2026) requires high-risk AI systems to maintain detailed logs of their operations. Article 12 mandates automatic recording of events for the entire lifecycle of high-risk AI systems.
This MCP server provides:
Tamper-proof logging — Each event includes the SHA-256 hash of the previous entry, forming an unbreakable chain
Integrity verification — Detect if any log entries have been modified, deleted, or reordered
Compliance reports — Export audit trails in JSON or human-readable format for regulators
Cross-agent search — Search events across all agents by keyword, type, or agent ID
Statistics — Event rates, error rates, and action frequency analysis

Entry 1: { data, prev_hash: "000...000", hash: "abc123..." }
Entry 2: { data, prev_hash: "abc123...", hash: "def456..." }
Entry 3: { data, prev_hash: "def456...", hash: "ghi789..." }If any entry is modified, its hash changes, breaking the chain for all subsequent entries. The verify_integrity tool detects this immediately.
pip install agent-audit-trail-mcpAdd to your MCP client config (e.g. Claude Desktop):
{
"mcpServers": {
"audit-trail": {
"command": "audit-trail-server"
}
}
}Or with uvx (no install needed):
{
"mcpServers": {
"audit-trail": {
"command": "uvx",
"args": ["agent-audit-trail-mcp"]
}
}
}Tool | Description |
| Log an immutable audit event with timestamp and hash chain |
| Retrieve audit trail for an agent (newest first) |
| Verify the hash chain is intact (no tampering) |
| Export audit trail as compliance report (JSON or text) |
| Search across all audit events by keyword |
| Get audit statistics (events/day, error rate, top actions) |
Audit logs are stored in ~/.agent-audit-trail/ as append-only JSONL files (one per agent). Each line is a JSON object with:
timestamp — ISO 8601 UTC timestamp
agent_id — Which agent performed the action
event_type — Category (decision, action, error, access, data_processing)
action — What was done
details — Full description
outcome — Result of the action
prev_hash — SHA-256 hash of the previous entry
hash — SHA-256 hash of this entry
