mcp-servers

The server correctly isolates sensitive API tokens by loading them from environment variables via a shared `env-loader.ts` utility, with explicit warnings in `MCP_SETUP.md` against hardcoding. Its primary mode of operation involves making internal MCP calls to other local Slack and Jira servers via `stdio` transport, which is a secure communication pattern. The Slack MCP server, a dependency, implements a critical security feature: it restricts the `send_message` tool to only the `#qa-release-status` channel, preventing arbitrary message posting. The Slack server also uses a local Ollama instance for LLM-based analysis, keeping data localized. The primary security concern lies with the powerful Slack `XOXC`/`XOXD` session tokens, which grant full user-level access and are equivalent to user credentials. Operators must ensure these tokens, along with Jira/Confluence API tokens, are managed with extreme care and never committed to version control. While the server's code handles these tokens securely, their inherent high privilege poses an operational risk if compromised externally.
