Claude Code to MCP Toolkit is timing out. #336
Description
I have been trying to connect claude code v2.1.5 on a Mac. It shows up in the list of mcps, tries to connect but then responds with red x. When I look in ~/.claude/debug/latest I see 'MCP server "MCP_DOCKER" Connection failed: Connection to MCP server "MCP_DOCKER" timed out after 30000ms'.
But if I run docker mcp gateway run on the command line no issues.
When I ask Claude Code what is going on it runs the command docker mcp gateway run and says that Docker is responding in a format that Claude Desktop can handle but Claude Code expects JSON-RPC 2.0 protocol.
I used the button in docker desktop to connect to claude code and I see that it adds the following to my ~/.claude.json
"mcpServers": {
"MCP_DOCKER": {
"command": "docker",
"args": [
"mcp",
"gateway",
"run"
]
}
}
I even tried it this way but didn't make a difference.
"mcpServers": {
"MCP_DOCKER": {
"command": "docker",
"args": [
"mcp",
"gateway",
"run"
],
"type": "stdio"
}
}
