mcp-graylog 0.3.1
Fixes Streamable HTTP 421 responses for deployments that use an external hostname or IP address.
- Adds explicit Host and Origin allowlists.
- Reads MCP_SERVER_* runtime settings from the environment and .env.
- Keeps DNS rebinding protection enabled by default with localhost-only values.
- Supports trusted proxy deployments that need to accept any host through MCP_SERVER_DNS_REBINDING_PROTECTION=false.
For a direct deployment, set MCP_SERVER_ALLOWED_HOSTS to the public hostname or IP, including the exposed port or the :* port wildcard.
