mcp_registry_install: invalid env: {e}

Error message

mcp_registry_install: invalid env: {e}

What it means

The "env" argument of mcp_registry_install failed to deserialize into HashMap<String,String> — some value is not a string (or the object is malformed). The tool schema declares env as an object with additionalProperties string.

Solutions

1. Make every env value a string (quote numbers and booleans)
2. Fix malformed JSON in the env object
3. Omit env entirely if no environment variables are needed
