Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`SEARCH_API` Optional, secret	SearchApi API key. Required only for SearchApi primary or fallback modes.
`SURF_SEARCH_PROVIDER` Optional	Provider for search and search_parallel: browser, searchapi, or fallback. Defaults to browser.
`SURF_SCHOLAR_PROVIDER` Optional	Provider for scholar_search: browser, searchapi, or fallback. Defaults to browser.
`SURF_BROWSER_ENGINE` Optional	Browser engine: auto, native, or playwright. Auto uses one hidden native Chrome broker shared across local MCP sessions.
`CHROME_PATH` Optional	Absolute path to the Chrome binary. Auto-detected on Windows/macOS/Linux when omitted.
`SURF_PROFILE_ROOT` Optional	Directory for the warm Chrome profile. Defaults to ~/.google-surf-mcp.
`SURF_RESEARCH` Optional	Enable Google Surf Auto Ontology: local project memory, evidence capture, and hybrid retrieval. Defaults to true. The SURF_RESEARCH setting name is unchanged.
`SURF_RETRIEVAL_MODE` Optional	Shared route for search and search_parallel: live or hybrid. Defaults to hybrid.
`SURF_RESEARCH_ROOT` Optional	Embedded SurrealDB data directory. Defaults to <profile>/research.
`SURF_RESEARCH_VECTOR_MODEL` Optional	Local model for HNSW retrieval and shared reranking. Defaults to Xenova/multilingual-e5-small; use off to disable.
`SURF_RESEARCH_VECTOR_LOW_MEMORY` Optional	Disable ONNX CPU memory arena and memory pattern. Defaults to true.
`SURF_RESEARCH_VECTOR_THREADS` Optional	ONNX intra-op thread count from 1 to 16. Defaults to 4.
`SURF_RESEARCH_REPO_AUTO` Optional	Sparse-index at most one eligible small GitHub repository per search call. Defaults to true.
`SURF_RESEARCH_REPO_AUTO_MAX_MB` Optional	Maximum searchable repository source-text size in MB. Assets are excluded. Defaults to 20.
`SURF_RESEARCH_REPO_AUTO_MAX_FILES` Optional	Maximum repository source file count for automatic indexing. Defaults to 2000.
`SURF_RESEARCH_BROKER_IDLE_MS` Optional	Shared Auto Ontology broker idle lifetime in milliseconds. Defaults to 60000.
`SURF_RESEARCH_READ_CONCURRENCY` Optional	Maximum concurrent Auto Ontology broker reads. Defaults to 4.
`SURF_RESEARCH_QUERY_TIMEOUT_MS` Optional	Timeout per embedded SurrealDB query in milliseconds. Defaults to 120000; timed-out retrieval lanes are reported as partial.
`GITHUB_TOKEN` Optional, secret	Optional token that raises GitHub API limits for repository inspection.
`SURF_LOCALE` Optional	Browser locale, e.g. en-US.
`SURF_TZ` Optional	IANA timezone, e.g. America/New_York. Defaults to system timezone.
`SURF_HEADLESS` Optional	Controls Playwright extraction, compatibility, and recovery paths. Native search hides normal system Chrome and shows it only for CAPTCHA recovery.
`SURF_IDLE_CLOSE_MS` Optional	Idle ms before closing the sequential ctx and pool. 0 disables idle auto-close. Defaults to 30000.
`SURF_ALLOW_PRIVATE` Optional	Set to 'true' to allow extract on private/loopback addresses (localhost, 10.x, 192.168.x, 169.254.x, etc). Default blocks them as an SSRF guard.
`SURF_LLM_HEAL` Optional	Enable the optional workflow-only LLM selector repair path. Defaults to false.
`SURF_LLM_PROVIDER` Optional	LLM selector repair provider: anthropic or orcarouter. Defaults to anthropic.
`SURF_LLM_MODEL` Optional	Optional model override. OrcaRouter defaults to orcarouter/auto.
`ANTHROPIC_API_KEY` Optional, secret	Anthropic API key for optional LLM-assisted selector repair.
`ORCAROUTER_API_KEY` Optional, secret	OrcaRouter API key for optional LLM-assisted selector repair.
