Tools as reported by the server

• get_server_info
  Use this first to confirm the ESG Hub MCP server is reachable and see its version and API base. It performs one liveness round-trip and returns only server metadata — name, version, API base, tool_count, and healthy — and never fails on an unreachable API: it returns healthy=false rather than an err
• search_esg
  Exact keyword (BM25) search across ESG Hub articles and curated external resources. Use when the user supplies a specific term, identifier, or phrase (e.g., 'GRI 305', 'Scope 3'); for paraphrased or conceptual questions prefer search_content, which adds semantic similarity. Terms are matched individ
• search_content
  Hybrid search that fuses 384-dim semantic similarity with BM25 and ESG re-ranking across ESG Hub articles and external resources. Use for conceptual or paraphrased questions — natural-language phrases work better than single tokens because `query` is embedded; when the user gives an exact identifier
• get_esg_page
  Read one ESG Hub article in full, addressed by permalink (e.g., 'standards/gri-101'), bare slug, or record ID ('page:abc123'). Use it once search_esg, search_content, or list_esg_pages has returned an identifier; to fetch a page's neighbours rather than its content use get_related. Returns the compl
• list_esg_pages
  Enumerate ESG Hub articles, optionally filtered by `section`, `pillar`, or a title substring (`query` — an exact substring, not fuzzy). Use it to browse a whole section; to find articles by meaning use search_content. Results are ordered by section then title and returned one page at a time: pass th
• list_esg_resources
  Enumerate curated external ESG resources (standards bodies, regulators, tools, databases) with their source URLs, optionally filtered by exact source `domain` or a title substring (`query` — an exact substring, not fuzzy). Use it to assemble authoritative references; for ESG Hub's own articles use l
• get_esg_metadata
  Discover the filter vocabulary for the knowledge base: total counts plus the exact `section`, `pillar`, and source-`domain` values with their counts. Call it before list_esg_pages or list_esg_resources so filters match real values; for server version and health use get_server_info. It takes no param
• get_term
  Look up one glossary term by record ID ('term:abc123'), permalink, or exact name and return its full definition and facets. Use it when the user asks 'what is <term>'; to find terms by topic, or across all content, use search_esg or search_content, and to survey the glossary use list_terms. Name mat
• get_related
  Traverse the ESG Hub knowledge graph one hop from a page and return every connected record grouped by edge type. Use it after get_esg_page when you need neighbouring concepts; to read a page's own content use get_esg_page. Returns at most 15 related pages and, today, only `related_pages` edges; a pa
• list_frameworks
  Enumerate the ESG reporting frameworks and standards the knowledge base covers (GRI, SASB/ISSB, TCFD, ESRS, CDP, TNFD, …), with each framework's abbreviation, description, and official website. Use it to discover coverage; for the ESG Hub articles that explain a standard use list_esg_pages with sect
• list_industries
  Return the ESG Hub industry taxonomy (IFRS/SASB-style): every industry with its stable `industry_id`, English/Chinese names, and the `sector_id` it belongs to. Use it to obtain valid industry values for tag_content or to group coverage by sector; for article sections and source domains use get_esg_m
• list_terms
  Enumerate glossary terms, optionally filtered by an exact name substring (`query` — case-insensitive, not fuzzy). Use it to survey the glossary or page through terminology; to fetch one term's definition use get_term, and to search all content use search_esg or search_content. Results are ordered by
