I’m having trouble with oAuth with my Claude Desktop to the Zapier MCP server. When I launch Claude Desktop, it redirects me to an oAUTH page for Zapier but I get an error:
Error: invalid_request
Mismatching redirect URI.
Below is my JSON Configuration file for Claude Desktop:
{
"mcpServers": {
"zapier-mcp": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp.zapier.com/api/mcp/a/16048681/sse"
]
},
"github": {
"command": "npx",
"args": [
"-y",
"@modelcontextprotocol/server-github"
],
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "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"
}
}
},
"globalShortcut": "Ctrl+Space"
}
