Trace Forge
Record structured execution traces and spans from your AI agent so you can debug flaky tool chains in production-like runs.
Overview
Trace Forge is an MCP server for the Operate phase that provides structured execution traces and span logging for AI agent runs.
What is this MCP server?
- Structured execution traces and span logging tailored to AI agents
- Helps reconstruct tool-call order when a solo build session goes wrong
- npm package trace-forge-mcp v0.1.1 with stdio MCP transport
- Designed to complement BYO LLM clients, not replace them
- GitHub-hosted open source at mdfifty50-boop/trace-forge-mcp
- Version 0.1.1 published as trace-forge-mcp on npm
- MCP transport type: stdio
- Repository: github.com/mdfifty50-boop/trace-forge-mcp
What problem does it solve?
Agent tool chains fail in opaque ways, and chat transcripts alone do not show span-level order and timing.
Who is it for?
Solo builders running custom MCP agents who need lightweight trace logging without adopting a full SaaS observability platform first.
Skip if: Static sites or pure codegen workflows with no recurring agent executions to observe.
What do I get? / Deliverables
After adding Trace Forge, you can log and inspect structured traces to pinpoint which agent step broke during real usage.
- Stdio MCP server wired for structured agent traces
- Span-oriented logs you can use to debug agent regressions
- Clearer post-mortems on multi-tool agent sessions
Recommended MCP Servers
Journey fit
Trace logging pays off after you ship agent workflows and need to see what actually ran—classic Operate monitoring, not ideation. Monitoring subphase because it focuses on spans and execution traces rather than unit tests or pre-launch security review.
How it compares
Agent-focused trace MCP, not a host-level metrics collector or error tracker like Sentry alone.
Common Questions / FAQ
Who is Trace Forge for?
Solo developers operating AI agents in production or staging who need structured traces when debugging tool and span failures.
When should I use Trace Forge?
Use it once agents run multi-step automations and you need span-level history beyond scrolling chat logs.
How do I add Trace Forge to my agent?
Install trace-forge-mcp v0.1.1 from npm, configure it as a stdio MCP server in your client, and invoke its tracing tools from your agent workflow.
