Debug MCP Agents With Evidence
When an agent misuses a tool, developers need more than a transcript. ProofMap helps isolate the failing criterion and test the fix.
Get StartedWhy Choose ProofMap
Replay failing cases
Run known scenarios after prompt, tool, or runtime changes to confirm the issue is fixed.
Check tool arguments
See whether the agent chose the right MCP tool and passed valid structured inputs.
Approve the fix
Promote only prompt packages and mappings that pass the regression suite.
Comparison
| Need | Ad hoc workflow | ProofMap |
|---|---|---|
| Connect tools and context | Developers wire custom integrations and debug behavior from raw logs. | Use MCP for standardized access and ProofMap to qualify tool behavior against objective tests. |
| Control production behavior | Prompt, model, and tool changes move through manual review or informal judgment. | Promote only prompt packages and runtime mappings that pass evaluation gates. |
| Save time and cost | Teams repeat setup, review, and model comparison work for every agent change. | Reuse tool connections, rerun objective suites, and compare cost, latency, and quality together. |
| Handle timing events | Launches, incidents, renewals, schema changes, and traffic spikes trigger rushed decisions. | Keep evidence-backed evaluations and fallback mappings ready before the timing pressure arrives. |
Frequently Asked Questions
What makes MCP agent debugging hard?
Failures can come from prompt wording, model behavior, tool schemas, permissions, or missing context. ProofMap helps separate those causes.
Can ProofMap test tool schema changes?
Yes. Treat schema changes as release events and rerun objective tests before rollout.
How does this save developer time?
ProofMap reduces repeated manual review, model comparison, prompt regression checks, and tool-use debugging by making them repeatable evaluation workflows.
What does ProofMap produce?
It produces objective-bound evaluations, failure evidence, recommendations, and approved prompt or runtime mappings that developers can use in production.
