Requires: OPENGROK_BASE_URL, OPENGROK_USERNAME, OPENGROK_PASSWORD, OPENGROK_VERIFY_SSL, OPENGROK_CODE_MODE, OPENGROK_ENABLE_MEMORY_TOOLS, OPENGROK_DEFAULT_PROJECT, OPENGROK_CONTEXT_BUDGET, OPENGROK_API_VERSION, HTTP_PROXY, OPENGROK_RESPONSE_FORMAT_OVERRIDE, OPENGROK_MEMORY_BANK_DIR, OPENGROK_LOCAL_COMPILE_DB_PATHS, OPENGROK_ENABLE_ELICITATION, OPENGROK_ENABLE_SAMPLING, OPENGROK_SAMPLING_MODEL, OPENGROK_ENABLE_FILES_API, OPENGROK_ENABLE_OBSERVATION_MASKER, OPENGROK_OBSERVATION_MASKER_TURNS, OPENGROK_SAMPLING_MAX_TOKENS, OPENGROK_AUDIT_LOG_FILE, OPENGROK_RATELIMIT_RPM, OPENGROK_PER_TOOL_RATELIMIT, OPENGROK_TIMEOUT, OPENGROK_DEFAULT_MAX_RESULTS, OPENGROK_PASSWORD_FILE, OPENGROK_MAX_RESPONSE_BYTES, OPENGROK_SEARCH_AND_READ_CAP, OPENGROK_STRICT_SSRF, OPENGROK_JWT_ISSUER, OPENGROK_GRAMMAR_DIR

Our take

A serious OpenGrok bridge for large internal codebases, with both classic search/read tools and a sandboxed Code Mode for multi-step investigations. The setup command can write MCP client configuration and stores credentials in OS keychain or encrypted fallback, but that happens through an explicit wizard rather than install-time mutation. Strong option if you already run OpenGrok; less useful as a general code-search service because it needs your own OpenGrok endpoint and credentials.
