Audit Log
A complete, immutable record of every tool invocation across all MCP servers in your workspace.
Audit Log
The audit log is a chronological record of every tool call that passed through MCPHub — via the proxy or direct ingestion. It's the ground truth for debugging, compliance, and usage investigation.
What's captured
For every tool call:
- Which tool was called and on which server
- Which agent or caller triggered it
- When it happened (timestamp to millisecond precision)
- How long it took (duration in ms)
- Whether it succeeded or failed (with error detail)
- Input and output token counts (if provided by the caller)
- Output payload size
Why this matters
Without an audit log, debugging MCP failures means grepping server logs, asking agents what they called, and hoping someone remembers what happened. MCPHub gives you a single searchable trail across all your servers.
