Agent Replay
Record and replay full agent execution traces so you can debug flaky tool chains without re-running expensive LLM steps blind.
Overview
Agent Replay is an MCP server for the Ship phase that records and replays AI agent execution so builders can debug tool workflows reproducibly.
What is this MCP server?
- Record AI agent execution for later inspection
- Replay captured runs to reproduce bugs without guessing
- Stdio MCP server via npm package agent-replay-mcp v0.1.1
- Complements Agent Guard and Agent Security in the same maintainer suite
- Local stdio transport suited to dev-machine debugging
- Server version 0.1.1
- npm package identifier agent-replay-mcp
- stdio MCP transport
What problem does it solve?
Agent failures are hard to reproduce because each rerun changes LLM output and obscures the exact tool sequence that broke.
Who is it for?
Solo builders debugging multi-step MCP tool chains who need session capture and replay on their own machine.
Skip if: Builders who only need aggregate metrics or security scans without step-level execution history.
What do I get? / Deliverables
After registering agent-replay-mcp, you can capture agent runs and replay them to isolate bugs without repeated full autonomous retries.
- MCP-accessible record and replay workflow for agent sessions
- Reproducible execution traces for local debugging
- npm-based install (agent-replay-mcp 0.1.1)
Recommended MCP Servers
Journey fit
Replay debugging fits the Ship phase when you validate agent behavior, reproduce failures, and harden workflows before wider release. Testing subphase is where recorded sessions become reproducible fixtures instead of one-off chat logs.
How it compares
Session record-and-replay MCP tool, not a production metrics dashboard or guardrail enforcer.
Common Questions / FAQ
Who is Agent Replay for?
Developers and indie builders using MCP agents who need to save and replay autonomous sessions when debugging integrations or flaky tools.
When should I use Agent Replay?
Use it when an agent workflow fails intermittently, when you refactor tools, or when you want teammates to step through the same captured run.
How do I add Agent Replay to my agent?
Install agent-replay-mcp (v0.1.1) from npm, add it as a stdio MCP server in your client configuration, and invoke record/replay tools from agent debugging sessions.
