What's Wrong?

• had some server api fixed with various things
• claude says "- /mcp reconnect mid-session → ❌ doesn't re-deliver env to the subprocess"

What Should Happen?

• the /mcp , reconnect should re-deliver env to the subprocess

"env": {
        "VERITAS_ENV_FILE": "/workspace/repos/jgwill/veritas/.env"
      }

Error Messages/Logs

Steps to Reproduce

1. Create an mcp that needs a correct variable but does not have it when you launch claude-code with the --mcp-config
2. once claude-code is launch, try to run the tool and expect it to fail
3. update the .env with adequate variable (that will make the MCP or logics working)
4. use /mcp reconnect in the claude-code session
5. Expect it to fail again. When fixed, we expect that to work
