"OpenSea" matching MCP tools:

• pipeworx_feedback

  Opensea

  Tell the Pipeworx team something is broken, missing, or needs to exist. Use when a tool returns wrong/stale data (bug), when a tool you wish existed isn't in the catalog (feature/data_gap), or when something worked surprisingly well (praise). ONLY for tools served by this Pipeworx connection — if the tool came from a different MCP server in your client (another vendor's Gmail, Splunk, Slack, etc. connector), we cannot fix it and reporting it here only delays you; file it with that server instead. Not sure? Pipeworx tool names are the ones this connection lists. Describe the issue in terms of Pipeworx tools/packs — don't paste the end-user's prompt. Filing without an account returns a `claim_token`; pass it back later as pipeworx_feedback({claim_token:"pwfb_…"}) to read whether it was fixed and what changed. The team reads digests daily and signal directly affects roadmap. Rate-limited to 5 per identifier per day. Free; doesn't count against your tool-call quota.

• ask_pipeworx_grounded

  Opensea

  Hallucination-resistant answer mode for high-stakes reads. Same routing as ask_pipeworx — picks the right tool from 5,710 across 1494 sources, fills arguments, fetches the data — then EXTRACTS the answer using ONLY what the tool result contains. Returns {answer, evidence (verbatim quote), confidence, source, fetched_at, refusal_reason:null} on success, OR an explicit refusal {answer:null, refusal_reason:"not_in_source"|"no_tool_match"|"tool_error"|"data_truncated"|"llm_error"} when the data doesn't directly answer. Use whenever an answer will be quoted, cited, or acted on, and the agent must not invent facts (financial verdicts, legal claims, medical lookups, public statements). Costs one extra LLM call vs ask_pipeworx — prefer ask_pipeworx for casual lookups.

• polymarket_arbitrage

  Opensea

  Find arbitrage opportunities on Polymarket via monotonicity violations + partition-sum checks. Call with NO args for a `trending_scan` of the top ~200 markets by weekly volume; pass `event` for the strongest per-event partition_check, or `topic` for a themed cross-event scan. `event` (recommended for a specific market): pass a Polymarket event slug like "fed-decision-may-2026" or "when-will-bitcoin-hit-150k"; walks child markets, checks date-axis / threshold-axis ordering AND computes the partition_check (sum of YES prices across mutually-exclusive legs — should ≈1; deviations >3pp emit a BUY/SELL EVERY LEG signal). `topic` (for cross-event scanning): pass a seed question like "Strait of Hormuz traffic returns to normal" or "Fed rate decision"; searches related events across the platform, flattens markets, runs the comparator on the union. Cross-event mode catches "...by May 31" vs "...by Jun 30" patterns that single-event misses. SEMANTIC ANCHOR: cross-event pairs require ≥0.30 Jaccard similarity on question tokens (prevents Powell-Fed-Pause being paired with Powell-DOJ-probe); skipped_low_similarity surfaces the rejected pair count. PARTITION FILTER: drops will-person-X / will-manager-Y / will-someone-else- placeholder slugs; partitions with >20% placeholder fraction return null arb signal. Response: opportunities[] (gap_pp, suggested_trade, reasoning, monotonicity violation context), and in event mode partition_check{sum_yes_prices, gap_from_1, placeholders_filtered, suggested_trade}. FILL CHECK: when the partition signal fires, arbitrage.fill_check prices it against live CLOB depth (theoretical_edge_pp_at_book vs realizable_edge_pp at 1000 shares/leg, thin_legs[]) — realizable_edge_pp ≤ 0 means the overround exists only at last-trade, not in the book; do not trade it. For custom sizing use polymarket_fill_risk.

• polymarket_fill_risk

  Opensea

  Realizable-vs-theoretical edge check against live CLOB order-book depth. REQUIRES one of `market` (single-market mode) or `event` (basket/partition mode). SINGLE-MARKET: pass a market slug/URL + side (buy_yes|sell_yes|buy_no|sell_no, default buy_yes) + size_usd (default 1000 — max spend on buys, target proceeds on sells); walks the ladder and returns top_of_book, vwap_fill_price, slippage_pp, shares_filled, max_fillable_usd, and a verdict (clean|degraded|cannot_fill). BASKET: pass an event slug/URL + side (sell_yes = capture overround by selling every leg, buy_yes = capture underround; default auto from partition sum) + size_usd interpreted as settlement notional S (shares per leg; each share pays $1); returns theoretical_sum vs realizable_sum (top-of-book vs VWAP across all legs), capture_ratio, profit_usd at executed size, per-leg fill detail, thin_legs[], max_clean_notional_usd, and forced_directional_risk naming the legs most likely to strand you unhedged. USE THIS before acting on any polymarket_arbitrage SELL/BUY-EVERY-LEG signal or any polymarket_edges trade above ~$500 — theoretical overround on thin books is not capturable, and partial basket fills convert an arb into an unhedged directional position (the dominant loss mode in real arb-bot P&L).

• remember

  Opensea

  Save data the agent will need to reuse later — across this conversation or across sessions. Use when you discover something worth carrying forward (a resolved ticker, a target address, a user preference, a research subject) so you don't have to look it up again. Stored as a key-value pair scoped by your identifier. Authenticated users get persistent memory; anonymous sessions retain memory for 24 hours. Pair with recall to retrieve later, forget to delete.

• create_listing

  Name Whisper — ENS Intelligence Layer

  List an ENS name for sale on NameWhisper's marketplace via Seaport 1.6. Returns an unsigned Seaport OrderComponents payload (plus EIP-712 domain/types) that the caller's wallet signs. After signing, POST the { orderComponents, signature, label, orderType: 'listing' } payload to https://namewhisper.ai/api/orderbook/submit (authenticated) to store the order. Fee structure: 1% marketplace fee baked into the order as a Seaport consideration item (seller-paid, not added on top). NW-native only — MCP listings stay on NameWhisper. If you want your listing on OpenSea too, list it separately through their interface. Requires the wallet to have approved NameWrapper (for wrapped names) or BaseRegistrar (for unwrapped) as an operator first. Use approve_operator if needed. Tip: Use get_valuation first to price competitively. Use get_name_details to confirm the name is unwrapped vs wrapped before listing.

  Connector

• cancel_offer

  Name Whisper — ENS Intelligence Layer

  Cancel an active offer you made on an ENS name. Returns unsigned Seaport cancel() calldata. Only the bidder (the order's offerer) can cancel. If the offer was cross-posted to OpenSea, you signed a second 'opensea' variant — pass BOTH order hashes as alsoCancel so one tx kills both. Cancelling releases the WETH you'd committed to the offer — the buyer's wallet keeps its WETH balance free to bid elsewhere once the Seaport order is invalidated. For cancelling your own listings, use cancel_listing.

• sweep

  Name Whisper — ENS Intelligence Layer

  Floor-sweep: buy the CHEAPEST N listed ENS names in a category/collection (or matching a filter) in ONE Seaport transaction. Use this when the user wants "the cheapest N", "sweep the floor", or "buy up to X ETH of" a cohort — rather than naming specific names (that's batch_purchase). Pick the cohort with 'category' (a collection slug like "999-club") and/or 'q'/'charType'/'minLength'/'maxLength'. Bound the sweep with 'count' (how many) and/or 'maxBudgetEth' (total spend), plus an optional 'maxPriceEth' per-name cap. It selects cheapest-first across NameWhisper, OpenSea, and Grails, then packs them into one fulfillAvailableAdvancedOrders call (capped at 20 names — run again to continue). NFTs are delivered directly to the buyer; Seaport skips any order that sold since discovery and refunds the excess. The response reports what was swept (with marketplace + price), the total, and how many matched but fell outside the bound.

• deep_research

  Opensea

  ACCOUNT REQUIRED (free — sign in via GitHub at https://pipeworx.io/signup; depth:"thorough" needs a paid plan). If you are not signed in, use ask_pipeworx instead — it works on every tier. Grounded multi-source research across Pipeworx's 1494 STRUCTURED data sources (SEC filings, FRED/BLS economics, FDA, USPTO patents, markets, science, government records, etc.) in ONE call — this is NOT open-web search. Decomposes your question into focused facets, routes each to the right one of 5,710 tools IN PARALLEL, and returns a findings packet: verbatim evidence + confidence + source + fetched_at + a stable pipeworx:// citation per finding, with explicit gaps[] for facets the data couldn't answer (never invented). Best for broad/multi-part questions over structured data ("compare X and Y's regulatory + financial exposure", "research the filings + market picture for ACME"). For a single lookup use ask_pipeworx (one LLM call, not many). For BREAKING or colloquial CURRENT-NEWS / "what's the world saying about X" topics, prefer ask_pipeworx — it routes to live news APIs and the *-news-feeds packs; deep_research returns mostly empty gaps[] when the topic isn't in the structured catalog. Second-hop iteration: depth:"standard" re-angles unanswered gaps (gap recovery); depth:"thorough" additionally chases the best leads from the first pass — so multi-step questions resolve in one call. Every finding carries a `hop` field and a citation_uri — a resolvable pipeworx:// record URI, present only when the source emits one that resources/read can actually serve, so a citation you get back is always fetchable. "standard" and "thorough" also return contradictions[] flagging findings that disagree. Large records are semantically excerpted to the passages relevant to each facet (not head-truncated), so answers deep in a long filing/series aren't missed. Expect 15-60s (thorough with its follow-up + contradiction pass: up to ~90s).

• entity_profile

  Opensea

  "Tell me about X" / "research Acme" / "brief me on Tesla" / "what does Apple do" / "company profile for Microsoft" / "give me the rundown on NVDA" / "everything you know about $TICKER" — full cross-source profile of a US public company in ONE parallel call. ALWAYS PREFER over chaining single-pack SEC/XBRL/news lookups when the user asks for a holistic view. Fans out across SEC EDGAR, XBRL, USPTO, news, GLEIF and returns: cik + company_name; recent_filings (up to 5 with pipeworx://edgar/company/{cik}/filings/{accession} URIs); fundamentals (LATEST 10-K Revenues + NetIncomeLoss + Cash, sorted period_end DESC); patents (USPTO PatentsView API sunset May 2025 — soft-fails until reactivated); recent news mentions via GDELT→GNews fallback; LEI via GLEIF. Pass ticker "AAPL" or zero-padded CIK "0000320193" — names not supported (use resolve_entity first if you only have a name).

  Connector

• recent_changes

  Opensea

  "What's new with X" / "latest on Y" / "what happened to Z this week / month / quarter" / "updates on Acme" / "news on Tesla recently" / "what's happening with Apple" — change feed for a company in the last N days/weeks/months in ONE parallel call. Fans out to SEC EDGAR (filings since `since`), GDELT→GNews fallback (news mentions in window — GDELT preferred, GNews when rate-limited or 5xx), USPTO (patents granted; PatentsView API sunset May 2025 so this soft-fails until reactivated). `since` accepts ISO date ("2026-04-01") or relative shorthand ("7d", "30d", "3m", "1y"). Returns structured changes[] grouped by source + total_changes count + pipeworx:// citation URIs. Use entity_profile instead when you want the static profile (filings + fundamentals + LEI + patents) regardless of window.

• ai_visibility_check

  Opensea

  Probe one or more LLMs for what they know about a business / brand / product / topic and score visibility (0-100) per model. Default model is Workers AI Llama-3.3-70b (free); pass `_apiKey` to also probe Anthropic (BYO key — you pay Anthropic directly for those calls). Returns per-model {score, confidence, signals, raw_response} + a combined view. Useful for AI-marketing audits, pre-launch brand checks, competitive monitoring.

• purchase_name

  Name Whisper — ENS Intelligence Layer

  Purchase an ENS name — either buy a listed name from a marketplace or register an available name directly on-chain. For AVAILABLE names: Returns a complete registration recipe with contract address, ABI, step-by-step instructions, and a pre-generated secret. Your wallet signs and submits the transactions (commit → wait 60s → register). For LISTED names: Searches all marketplaces (OpenSea, Grails) for the best price. If there are MULTIPLE active listings, returns CHOOSE_LISTING status with all options — present these to the user and ask which one they want. When the user chooses, call this tool again with the chosen orderHash to get the buy transaction. The tool auto-detects whether the name is available or listed. You can override with the 'action' parameter.

  Connector

• cancel_listing

  Name Whisper — ENS Intelligence Layer

  Cancel an active ENS name listing by submitting Seaport's cancel() on-chain. Returns the unsigned Seaport cancel() transaction calldata. Your wallet signs and submits; once mined, Seaport marks the order invalid and no marketplace (NW, Grails, OpenSea) can fulfill it anymore. Only the original seller (the order's offerer) can cancel. If you cross-posted to OpenSea, you signed a second 'opensea' variant of the listing — pass BOTH order hashes as alsoCancel so a single tx kills both variants atomically. For cancelling offers you've made as a buyer, use cancel_offer instead.

  Connector

• accept_offer

  Name Whisper — ENS Intelligence Layer

  Accept a standing offer on an ENS name you own. Returns unsigned Seaport fulfillOrder() calldata. When you submit this transaction, Seaport atomically: - Pulls the offered WETH from the buyer's wallet - Transfers the ENS name from your wallet to the buyer - Pays the 1% marketplace fee from the WETH You receive the offer amount minus the 1% fee. The buyer needs a live WETH balance + approval for Seaport/OpenSea conduit — if either is missing the tx will revert; you'll have signed but the chain won't execute. Before accepting: you must have approved Seaport (or the OpenSea conduit, for cross-posted offers) on NameWrapper (wrapped name) or BaseRegistrar (unwrapped). Use approve_operator if needed. Use get_name_details to see the offer hash and confirm the highest offer.

  Connector

• get_token_approvals

  Teardrop

  Audit ERC-20 token allowances for a wallet address. By default, returns all non-zero approvals for assets in the shared tracked-asset registry across curated DeFi protocol spenders (Uniswap, Aave, Compound, 1inch, 0x, OpenSea). Flags unlimited approvals with risk levels: high=unknown spender, medium=trusted protocol, low=bounded amount. Use before swaps to verify approval state, or after security incidents to detect active exploit vectors. Ethereum mainnet and Base only.

  Connector

• recent_alerts

  Opensea

  Pull fired events from your subscription feed. Returns the most recent alerts the evaluator has written to your persisted feed — each carries source, citation_uri (pipeworx:// when available), and the raw event payload. Filter by type (e.g. "sec_8k") and/or since (ISO timestamp). Set mark_read:true to flag returned events read so the next call only shows newer ones. Polls work fine; the same feed is also at GET registry.pipeworx.io/alerts.json for scripts and dashboards.

  Connector

• get_collection

  Opensea

  Fetch a collection by OpenSea slug. Returns name, description, contracts, social links, fees, image, banner. Find slugs at opensea.io/collection/<slug>.

  Connector

• register_agent

  Name Whisper — ENS Intelligence Layer

  Register an ENS name as an ERC-8004 agent identity on Ethereum mainnet. Returns a ready-to-sign transaction. Default route binds the agent to the name itself (ERC-8217 via Adapter8004): whoever holds the name controls the agent, OpenSea shows the agent identity on the name's page, and the agent transfers with the name when sold. Alternative "direct" route mints the agent NFT to your wallet instead. The agentURI defaults to a NameWhisper-hosted registration file generated live from the name's ENS records — set your agent-context and agent-endpoint records (set_ens_records) and the file updates automatically. IMPORTANT: after this transaction confirms, read the new agentId from the receipt (topic 1 of the Registered/AgentBound event) and call set_ens_records with the agentRegistration shorthand to write the ENSIP-25 binding record. The identity is not verifiable until that record is on-chain.
