web_searchSearches the web and returns ranked results. Supports `strategy` (`fallback`/`aggregate`/`auto`), `domain`, `from_date`/`to_date`, `format` (`text`/`json`), and `deep=true` for source-backed answers.fetch_contentFetches a URL and returns clean Markdown with content caching, charset handling, GitHub Raw fast paths, RSS feed extraction, and Playwright fallback.researchResearches a question in one call: checks the local knowledge base, searches the web, reads the top pages (`max_sources`, default 3), answers with citations from both, and adds the pages it read to the knowledge base (`index=false` to skip; sources already indexed are not added again).server_statusReturns provider availability, cache stats, knowledge index stats, memory stats, entity graph stats, recent search traces, browser state, routing profile metadata, feature flags, and uptime.ingest_documentChunks a document and indexes it into the local knowledge base (FTS + vectors) and entity graph. Pass `content`, or `path` to a local PDF, DOCX, EPUB, HTML or text file inside `INGEST_ALLOWED_DIRS`.index_urlFetches a URL and indexes its Markdown into the local knowledge base and entity graph.search_indexHybrid keyword + semantic search over the local knowledge base; returns chunks with source citations. Supports `format: "json"`.list_indexLists documents stored in the local knowledge base.rememberStores a short fact or note in session memory.recallSearches or lists session memory notes.forgetDeletes a session memory note by id.find_relatedExplores the entity graph: related documents and co-occurring entities for an entity name.
