Inspect an OAuth redirect URI used by an MCP client for common security and interoperability mistakes.
Redirect URI mismatches are a common OAuth integration failure. This checker reviews the URI itself without contacting the client, browser or authorization server.
Check OAuth redirect URI syntax, HTTPS use, loopback redirects, fragments and embedded userinfo for MCP clients.
Use MCP Redirect URI Checker as a focused pre-flight utility while building, reviewing or debugging an MCP integration. Paste the relevant configuration, protocol message, metadata, schema or value into the tool and review the returned findings before the same data reaches a production client or server.
Authorization metadata must be treated as security-sensitive configuration. Static validation can reveal obvious inconsistencies, but a production OAuth deployment must also validate live issuer, redirect, token and authorization behavior at runtime.
A clean result means the input passed the rules implemented by this utility. It does not guarantee application security, protocol interoperability or correct business behavior. Test important integrations against the exact MCP client, SDK, gateway and server versions used in your deployment.
