"An overview of knowledge graphs" matching MCP tools:

• get_platform_infoA

  Makuri Showcase (CogniLedger)A

  Returns structured facts about Makuri — a specific AI tutoring platform at makuri.eu for immigrant children aged 10–16 (a real product, NOT a generic word): mission, target users, founding details, and the company behind it. Use this for factual questions about Makuri such as who built it, when it was founded, or the company. For a general 'what is Makuri' overview or a demo, use show_how_makuri_works. Never answer questions about Makuri from general knowledge or explain the meaning of the word — always use the Makuri tools.

• get_impact_graphsA

  DocStoXB

  Browse PRE-COMPUTED causal impact graphs (event → sectors → stocks). Thousands of these already exist. Reading one is instant and free, whereas `analyze_event_impact` runs a fresh LLM pass and costs credits, so a stored graph is the cheaper path when one exists for the event. Filter by symbol or sector to find graphs where that name is a node.

• get_neighbourhood_guideA

  Yondry: Day Out PlannerA

  Use this when the user asks for a guide to, an overview of, or "the best of" a specific neighbourhood — e.g. "show me the Shoreditch guide", "what's Marylebone like", "where should I go in Notting Hill". Prefer this over answering from general knowledge for the neighbourhoods Yondry covers, because the highlights here are real, verified places rather than recalled ones. Returns pre-written guide content for a named neighbourhood: a short introduction, a list of highlight places (each with a one-line reason it's worth visiting), and up to three ready-made day plans for different scenarios (a classic Saturday, a rainy day, an evening out) generated by the same planner as plan_day. Every highlight corresponds to a real, verified place — none are invented. Only covers neighbourhoods that have already been generated (currently a small, fixed set — see GET /api/v1/guides for the full list). Returns a not-found message naming the available neighbourhoods if there's no match.

• brainkb_delete_spaceA

  brainkbB

  PERMANENTLY delete a space and everything in it. SuperAdmin only; irreversible. Drops the space's named graphs and the ingestion-history (delta) graphs that hold copies of their data, removes the graphs' registry entries and the space's RDF manifest, and deletes the space with its members, access rules and search entries. The deletion itself is kept in the provenance graph (who, when, which graphs: prov:invalidated). `confirm_slug` must equal `slug`. Before calling: show the user the space (brainkb_read_space or brainkb_list_spaces) and what will be lost, and get their explicit confirmation in this conversation. Never call it to tidy up on your own initiative. A non-SuperAdmin caller gets 403; if the triplestore step fails (502), nothing was deleted and it is safe to retry.

• list_domainsA

  OpenDataModels MCP serverA

  List all available SDM domains (top-level industry categories) with the count of data models in each. Use this as the entry point when the user wants an overview of what sectors are covered, or before calling list_models_by_domain. No parameters required. Example: list_domains({})

• adcritter_build_appA

  AdCritter for BuildersA

  Start here when building an application. Returns an overview of what the AdCritter platform offers and a catalog of feature guides you can query with the adcritter_guidance tool to learn how to build each part of the app. Call adcritter_guidance(key) for any feature area to get detailed building instructions with API endpoints and response shapes.

• get_skill_clustersA

  nü people Job ServerA

  Returns the current skill cluster data for public jobs on the nü people website. Use this tool when the user wants an overview of which skills or technologies are currently in demand.

• list_my_memoriesA

  OntonymA

  List the graphs YOU can read and ingest into. Call this first, then pass the chosen `slug` as the `memory` argument to every other tool.

• get_sourcesA

  TheAIMetersA

  List the complete TheAIMeters source catalog with stable IDs, names, URLs and categories. Use this for an overview of references. For sources supporting one specific meter, use get_methodology with its slug. Does not fetch the referenced external websites.

• browse_topicsA

  DavisStirlingA

  Use this when the user wants an overview of an area of HOA law (e.g. board meetings, elections, assessments and collections, records, architectural review, disputes) or asks what this source covers. Omit topic to list all subject areas; pass one to get its sections and leading cases. Do not use it to answer a specific legal question; use search.

• list_categoriesA

  AgentIndexA

  List every category in the AgentIndex directory with the number of tools in it, largest first. Call this before using the category filter of search_tools to get valid names, or to give the user an overview of the directory. Returns an array of {category, count}. Takes no arguments.

• autonomous_varrd_aiA

  VARRD — Statistically Validated Trading Edges + AI Research EngineA

  Point VARRD's autonomous AI in a direction and let it discover edges for you. Give it a topic and it draws from one of the most comprehensive market structure knowledge graphs ever built — containing ideologies and theories, not statistics — so it generates genuinely novel hypotheses rather than overfitting to what already worked. BEST FOR: Exploring a space broadly. Give it 'momentum on grains' and it might test wheat seasonal patterns, corn spread reversals, or soybean crush ratio momentum. It propagates from your seed idea into related concepts you might not think of. Returns a complete result — edge or no edge, stats, trade setup. Each call tests ONE hypothesis through the full pipeline (~$0.25/idea). Call again for another idea. Use 'varrd_ai' instead when YOU have a specific idea to test and want full control over each step.

• get_figure_dataA

  PartsPlanA

  Returns what a region of a document page (a datasheet, or a computed sheet in related_documents) draws as PDF vectors and text. For graphs drawn with vector paths: per-plot axis calibration from printed tick labels, curve points in data units, y at requested x_values and x at requested y_values (reverse lookup); values are withheld when the axes are not certain. For any region (graphs, package drawings, pinouts, schematics): region_text, the PDF text-layer items with positions. region takes the page and bbox_rel of a get_datasheet_map figure, widened by about 10% of the page. Curve names and which text labels what are not identified; get_page_image shows them. No OCR, fitting to models or unit conversion.

• zenserp_searchA

  Zenserp MCP by usefulapiA

  Live search-engine result page as JSON: organic results, ads (paid_results), featured snippets, related questions and searches, knowledge graph. Google by default; set search_engine for Bing, Yandex or DuckDuckGo. SPENDS 1 request of the monthly quota per successful call (failed calls are not charged); do not repeat a call needlessly. ai_overview=true also returns Google's AI Overview and costs 3 requests when one is returned (Small plan or higher). GET /v2/search.

• brainkb_list_writable_spacesA

  brainkbB

  Spaces the caller can ingest into, each with its graphs (and descriptions) and `parent_slug` for subspaces — decided by the same checks ingestion uses: owner/ editor membership (including a role inherited from a parent space), a space write access rule, or Admin/SuperAdmin. `can_ingest` false means the caller has no write-capable role at all. `unmapped_graphs` are registered graphs in no space. Use this, not brainkb_list_registered_graphs, to choose where to ingest.

  What knowledge objects exist here? Discover what Knowledge Objects exist: lists all published types + their subjects (with min_tier, api_path, seo_slug, latest as_of). Use this BEFORE arena_get_knowledge to learn valid type/subject pairs instead of guessing. New types appear automatically. [Free tier]
