Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
Check whether an MCP server's tool definitions have changed since it was last trusted (rug-pull / schema-drift detection, the CVE-2025-54136 class). Returns how long the tool surface has been stable, how many times it has changed, and the last change. Use after approval to detect post-trust mutation.
The MCP server endpoint URL to check.
This tool isn't marked read-only, so it may change something on the server or in an account you connected.

}Independently grade an MCP server (A–F) BEFORE connecting an agent to it. Returns spec-conformance, security (OWASP MCP Top 10), reliability, tool-hygiene and transparency sub-scores plus a connect/caution/avoid recommendation. Audited by wmcp.sh; the grade is free and never for sale.
| Argument | Type | Description |
|---|---|---|
| url* | string | The MCP server endpoint URL to grade (e.g. https://mcp.example.com/mcp). |
| fresh | boolean | Force a live re-probe instead of returning a recent cached grade. |

}Verify an MCP server immediately BEFORE you execute any of its tools. Combines the continuously-watched trust grade and live drift status into a single connect/caution/avoid verdict (ok | caution | drifted | failing | ungraded), so you can gate the call in one step. Free, read-tier. The grade is independent and never for sale.
| Argument | Type | Description |
|---|---|---|
| url* | string | The MCP server endpoint URL you are about to call. |
| fresh | boolean | Force a live re-probe instead of returning a recent cached grade (<6h). |
