"Reverse engineering or reverse direction search" matching MCP tools:

• secedgar_find_holders

  secedgar-mcp-server

  Find which institutional managers reported holding an issuer, by searching 13F-HR information tables for one reporting quarter. This is the reverse direction of secedgar_get_institutional_holdings: that tool takes a manager and returns its portfolio, this one takes an issuer and returns its managers — pass a returned filer_cik plus the same quarter to read the actual position. Searching by cusip is the precise path, matching the identifier the information table itself carries; without it the issuer name is matched as a phrase against the filing text, which both over-matches (unrelated issuers sharing a word) and under-matches (managers writing the name differently), so prefer cusip whenever one is known. A CUSIP cannot be derived from a ticker here — read one off any 13F information table returned by secedgar_get_institutional_holdings. The returned list is unranked: the search index scores by text relevance, which carries no signal about position size, and no ordering by shares or market value is available without opening each filing. Managers holding under $100M in 13(f) securities are exempt from filing at all.

• set_primary_name

  Name Whisper — ENS Intelligence Layer

  Set the primary ENS name (reverse resolution) for a wallet address. This controls what name is displayed when someone looks up your Ethereum address. For example, instead of seeing "0x1234...abcd", they'd see "myname.eth". Requirements: - You must own or control the ENS name - The name's ETH address record must point to your wallet - Only the wallet owner can set their own primary name When a user says "set my primary name" / "make X my primary", JUST call this tool — it bundles BOTH transactions (set the ETH address record + set the reverse record) into a single sign-card. Do NOT also call set_ens_records separately for this. After the user signs, verify it landed with get_primary_name. Only one primary name per address — setting a new one replaces the previous.

• resolve_merkle_root

  Lightyear CryptoPunks

  Reverse-engineer a Merkle root back to its punk IDs and inferred trait selection. ONLY works for roots that already have at least one bid in the CryptoPunks Bids API — this tool looks bids up by root, then derives trait config from the resulting punk set. Returns `resolved: false` for unknown roots; constructing a root locally and passing it here will not work. Rate limit: 5 per 10 min (compute bucket — shared with filter_punks, compute_merkle_root).

• fiscal_utility

  Drillr — The financial MCP for AI agents

  Use to convert between fiscal year/quarter and calendar months for a ticker before filtering period_end columns. Coverage warning: fiscal-year configuration is primarily US, with sparse JP/HK entries and no China A-share coverage in the verified dataset. Do not assume this tool supports a ticker merely because the core equity tables do. Forward: ticker + fiscal_year + fiscal_quarter → period_start/period_end. Reverse: ticker + yyyy_mm → fiscal_year/fiscal_quarter.

• list_memories

  memxus

  List recent memories in reverse-chronological order (read-only). When to use: audit what is saved, browse a collection, or collect memory IDs for get_memory or forget. When NOT: semantic search by topic → recall; one full record → get_memory; aggregate counts only → memory_stats. Behavior: default 20 results (plan-capped), ordered by created_at descending; empty set returns a message suggesting remember; full_content controls preview in the message text (120 chars); structured memories[] always includes full content. To list a team workspace instead of personal memory, pass workspace: <name>.

• bundle_geocode_enrich

  gisgp

  PAID (30 credits PER ADDRESS, max 10 addresses/call) — batch geocode + enrich. For each address: forward-geocodes to lon/lat (free fallback chain: OSM Nominatim -> Photon -> US Census), then reverse-geocodes for country/region/locality context and classifies land cover at that point. Replaces 3 separate calls per address: geocode_address + analyze_location + classify_land_cover. Use estimate_cost(tool_name= "bundle_geocode_enrich", units=<address count>) first to quote. Requires Authorization: Bearer <api_key> and sufficient credits balance. Returns JSON: {ok, results: [{address, ok, lon, lat, display_name, geocode_source, country, region, locality, land_cover} or {address, ok:false, error}], evaluated, failed_count}.

• mercury.ach_authorize

  DPX — Institutional Cross-Border Settlement

  Screen an ACH payment through the DPX compliance oracle before execution. Runs FATF R16, GENIUS Act, MiCA, and AML checks against the recipient. Returns APPROVED / FLAGGED / BLOCKED with full compliance reasoning. Use this tool BEFORE every ACH payment via mercury.send. ACH is hard to reverse — compliance pre-screening prevents blocked transactions and BSA/AML exposure. Workflow: 1. mercury.ach_authorize (screen only, autoExecute:false) → review decision 2. If APPROVED → set autoExecute:true to send, or call mercury.send directly 3. If FLAGGED → manual review required before proceeding 4. If BLOCKED → do not proceed

• nausika_geocode

  Nausika

  Resolve a place 'query' to coordinates (forward) or find nearest places to 'latitude'+'longitude' (reverse). Mediterranean-focused curated DB; forward falls back to OSM/Nominatim globally. Each result carries a 'source' discriminator ('local' for the curated marine DB, 'osm' for the global fallback). Returns name, type, coords, source, plus similarity (forward) or distance_m (reverse). Example forward: query="Portofino". Example reverse: latitude=44.3, longitude=9.21, radius_m=50000. Chain into nausika_marine_forecast, nausika_tides, nausika_search_places, or nausika_sea_route using the returned coords.

• secedgar_search_concepts

  secedgar-mcp-server

  Search supported XBRL financial concepts by keyword, statement group, or taxonomy. Use before secedgar_get_financials or secedgar_fetch_frames to discover the right friendly name, or pass a raw XBRL tag (e.g., "NetIncomeLoss") to reverse-lookup which friendly names map to it. Empty search with no filters returns the full catalog.

• lookup_lei

  nordic-data

  Look up a Legal Entity Identifier (LEI) via GLEIF — the global standard for entity identification. Returns legal name, registered address, status, parent + ultimate parent relationships, and child entities (subsidiaries). Also supports reverse lookup from a national company number to LEI across 15 countries (DK, NO, SE, FI, IE, UK, FR, DE, CZ, PL, LV, EE, NL, BE, LU). Tier note (reverse mode only): NL and DE use paid upstream registries — free-tier API keys receive HTTP 402 'upgrade_required'; do NOT retry on 402.

  Connector

• session_create

  workbench

  Start a scratch session that holds several named sequences/values (e.g. vector, insert, forward/reverse primer) for use across multiple tool calls via session_run, instead of re-pasting them into every call. Sessions expire after 24 hours.

• calc_reverse_charge

  Imperio — Italian Tax & Compliance Tools

  Calcola l'IVA che il CESSIONARIO deve autoliquidare in regime di inversione contabile e restituisce gli obblighi delle due parti con la norma applicabile. Distingue i tre casi che si confondono più spesso: reverse charge INTRACOMUNITARIO (cedente UE non-IT — art. 46 DL 331/93 per i beni, art. 17 c. 2 DPR 633/72 per i servizi), reverse charge INTERNO (cedente italiano — art. 17 c. 6, che NON è generalizzato: vale solo in settori tassativi come subappalti edili, rottami, pulizia edifici, elettronica) e paese non-UE (errore esplicito, non un ramo implicito).

• methodist_traverse

  OpenArx

  Multi-hop traversal from a claim over typed relation edges of ONE class. Default walks the epistemic §7 edges transitively (support/extend/qualify/refute/background/shared_evidence/same_as); relation_class="engineering" walks the dependency graph (depends_on/satisfies). ★ Those are the values a record carries; the graph stores them as ENG_DEPENDS_ON/ENG_SATISFIES edges, which you never write. This sentence used to name the epistemic set by its RECORD values and the engineering set by its EDGE LABELS, so a reader applying the visible pattern produced `ENG_depends_on` — a third thing, rejected by the validator (which accepts exactly depends_on and satisfies). direction="out" = forward (dependencies / cited); "in" = reverse (impact set — who depends on this). ★ This `direction` is the TRAVERSAL direction of the read and has NOTHING to do with the `direction` FIELD on a relation record — different thing, same name. Do not copy in/out into a record. For engineering it also returns cycle_detected (start claim in a dependency cycle). Class label-spaces are disjoint — a §7 walk never crosses into engineering edges and vice versa.

• citations

  Opencitations

  "Who cites paper [DOI]" / "what papers reference [DOI]" / "incoming citations to [paper]" / "what work has cited [study]" — DOIs that CITE the given DOI (reverse-direction from references). Use for impact analysis, follow-on research discovery, "is this paper influential" questions.

• tickerbot_get_ticker_holdings

  mcp-server

  Get an ETF's constituent holdings and their weights, heaviest first. When the ticker is not an ETF, `is_etf` is false and `holdings` is empty; `is_etf: true` with zero holdings means a real ETF whose holdings aren't ingested yet. (The reverse lookup "which ETFs hold NVDA" is a scan filter on the `etf_holders` column, not this tool.)

• calc_split_payment

  Imperio — Italian Tax & Compliance Tools

  Calcola la scissione dei pagamenti per le forniture alla Pubblica Amministrazione (art. 17-ter DPR 633/72): il fornitore fattura imponibile + IVA ma incassa dalla PA il SOLO imponibile, mentre l'IVA la versa la PA direttamente all'Erario. Restituisce i due importi separati, l'impatto di liquidità per il fornitore e le istruzioni FatturaPA (EsigibilitaIVA=S; NON si usano i codici Natura N6, che sono solo del reverse charge). Gratis (€0), deterministico, nessun login richiesto.

• geocode_address

  gisgp

  Forward-geocode a free-text address to lon/lat. Default: OSM Nominatim (no key, free, fair-use rate limited) — the complement to analyze_location's reverse geocode. Optional agol_token: route through Esri's own World Geocoding Service instead for more authoritative matches — uses YOUR OWN AGOL credentials/quota, not GISGP's (no extra charge either way, no GISGP account needed for this option). Returns JSON: {ok, lon, lat, display_name, type, importance, source}.

• picsart_media_export

  Picsart GenAI

  Render a fully-authored MP Scene to a final file via the server-side `media-platform/v3/export` workflow, returning the output URL(s). `format:"video"` (default) renders an MP4; `format:"image"` renders a single PNG still. Unlike a pure scene→scene deck compiler, this performs the ACTUAL render: it translates the scene to a V3/Replay project and dispatches it to the export service over an authenticated HTTP call — no local renderer. Auth is handled by the platform automatically — no token setup needed on your end. Validate the scene (`picsart_media_validate_scene`) and check a frame (`picsart_media_contact_sheet` with `times:[t]` — sample one frame near the point you want to verify; it returns that frame as an inline image you can look at) BEFORE exporting. If you do not yet have a scene, get the whole sequence from picsart_media_quickstart rather than reverse-engineering the document shape from picsart_media_get_scene_schema.

  OpenAccountants

  Full-text search across all published tax and accounting skills. Find, lookup, query, or discover skills by keyword, tax concept, deduction type, form number, or regulation (e.g. 'home office deduction', 'crypto capital gains', 'reverse charge', 'Schedule C', '60-day reporting'). Optionally limit to one jurisdiction. Use this when you don't know the exact skill slug. Set content_type='method' to discover step-by-step METHODS (guided procedures — what you EXECUTE via start()) instead of reference material; each method carries a review_status (accountant-reviewed | source-cited).
