Custom MCP servers
Point us at your own MCP servers and we'll catch tool and schema changes before they trip up your agents.
Catch MCP tool changes before they trip up your agents.
AI agents take whatever an MCP server tells them at face value. Point us at your servers and we'll flag the moment a tool, capability, or schema shifts underneath.
Add your first custom MCPTool schemas, line by line
We snapshot the server's tools list — every name, description, and input schema — and diff it on every polling cycle.
Agent safety first
A renamed tool or a tightened input schema can silently break an agent. We label changes by severity so you know what actually matters.
Only you can see them
Your custom MCPs live on your account. No one else sees the URL, the diffs, or the history.
Cadence scales with your plan
Every 24 hours on Free, down to every 30 minutes on Business. Same diff engine, same severity sorting as our API monitors.
Three custom monitors, free, forever.
