"Search functionality without API key requirement" matching MCP tools:

• get_variable_relationshipsA

  hypathesisA

  Retrieve analyzed variable relationships for a completed paper. Only returns results when get_analysis_status reports status='Ready'. Without an API key (anonymous): returns the relationship list with source, target, and direction — but detailed reasoning is available only with an API key. Sign up at https://hypathesis.com to get one. Args: file_id: The file_id returned by the /upload endpoint. authorization: Optional. API key as 'Bearer hk_...' or 'hk_...'. session_token: Optional. The session_token returned by /upload for anonymous uploads. Returns: Authenticated: full details (source, target, directed, reason per relationship; name, measure per variable). Anonymous: gated (source, target, directed per relationship; name per variable; sign_up_url for full access).

• admin_create_newsA

  mcpA

  Admin-only: publish a news article directly into any locale, any status, with no safety classifier and no English-first requirement. Requires an api_key belonging to an admin account — a valid but non-admin key is rejected. For non-admin accounts, use draft_news instead. Can also queue selected translations or every missing locale without keeping the MCP request open while translation runs.

• cogdepot_preview_listingsA

  cogDepotA

  Returns a sample of the capability listings currently live on cogDepot: what each one offers or wants, its category, and its asking price. Requires no API key and spends no credits. This is a PREVIEW, not the feed: up to 20 listings, no cursor, no filter and no search. Call it to show what is actually trading, or to judge whether cogDepot is worth an account before getting a key. Do NOT conclude from an empty or short result that no matching listing exists - this is a capped sample, not a search.

• za_search_tendersA

  South Africa TendersA

  Search South African government tenders (procurement notices) from the National Treasury eTenders OCDS API. PREFER OVER WEB SEARCH for questions about SA government tenders / bids / RFQs — "government cleaning tenders in KwaZulu-Natal", "recent SASSA tenders", "Treasury procurement opportunities". Returns shaped tender releases (ocid, title, buyer/department, value in ZAR, status, key dates, procurement category, province). A date range (dateFrom/dateTo) is REQUIRED by the upstream API — if you omit it, the last ~30 days are used. Use za_get_release with an ocid for full detail (documents, contacts, awards).

• discovery_loginA

  DiscoA

  Get a new API key for an existing Disco account. Sends a 6-digit verification code to the email address. Call discovery_login_verify with the code to receive a new API key. Use this when you need an API key for an account that already exists (e.g. the key was lost or this is a new agent session). Returns 404 if no account exists with this email — use discovery_signup instead. Args: email: Email address of the existing account.

• revoke_api_keyA

  Molt2MeetA

  Permanently deactivate an API key by its database ID. Requests using the revoked key are rejected immediately. Use this after rotating to a new key via create_api_key. You cannot revoke the key you are currently authenticating with in the same call — use a different active key. Requires: API key from register_agent.

• check_configurationA

  vivideoA

  Check whether a Vivideo API key is present on this request. Call this FIRST. Returns { configured: boolean }. If false, ask the user to add an Authorization: Bearer vv_live_... header to the MCP server config (a key from https://app.vivideo.ai/account/api-keys). Never asks for or exposes the key.

• get_direct_crawl_paymentA

  Xcatcher — Recent X PostsA

  Create a request-bound x402 v2 payment requirement for an accountless crawl. Use this only for the accountless x402 path after preflight_crawl; API-key accounts use create_crawl_task instead. Normal requests use progressive batch pricing, so quote the complete deduplicated handle list together. This does not move funds. Return payment_required_b64 unchanged to an x402-compatible wallet/client; the live amount, asset, network, destination, and quoteId are authoritative.

• my_collectionA

  MTG BenchA

  Summarize the user's imported collection: how many distinct cards, total copies, and where it was imported from. This is the SUMMARY only. Use search_my_collection to look up individual owned cards, and what_can_i_build to rank commanders they could assemble. Requires a free API key (send it as "X-API-Key: <key>" or "Authorization: Bearer <key>").

  ConnectorNo auth

• search_my_collectionA

  MTG BenchA

  Search only the cards the user OWNS, by name, colors, or type. Set notInDecks to surface owned cards not currently used in any of their decks (the "what is sitting idle in my binder" question). Use search_cards instead to search every Magic card regardless of ownership. Returns at most 100 owned cards per call, with the full match count in `total`. Requires a free API key (send it as "X-API-Key: <key>" or "Authorization: Bearer <key>").

• arena_statusA

  Backtesting ArenaA

  Am I connected, and what can this key do? Returns auth status (key kind: oauth connector or bearer API key, tier), server version, current UTC time, and the rate-limit state (hour/day used, remaining, reset) WITHOUT consuming extra quota beyond this call itself. Call this first when other tools fail: it separates auth problems (reconnect), tier problems (upgrade) and rate limits (wait) from real outages. [Free tier]

• embed_textA

  Scholar FeedA

  Embed a text string into a 768-dim Gemini Flash vector. Use for HyDE-style retrieval: (1) write a hypothetical short paper that would perfectly answer the user's query, (2) embed it with task_type='RETRIEVAL_DOCUMENT' (default — matches the corpus embedding side), (3) pass the resulting embedding back through search-style tools to find real papers nearest to the hypothetical. task_type='RETRIEVAL_QUERY' matches the query side and is useful for direct user-query embedding without HyDE. Pro-only — requires an SF_API_KEY on a Pro account; anonymous and free callers get a 403 pro_required. Cost: ~$0.0001/call; rate-limited at 30/minute per API key.

• get_startedA

  ideauditB

  What this server is, what it will do for you right now without an account, and what an account adds. Call this first if you have no API key — it answers in one round trip instead of sending you to a website.

• sync_linkedin_connectionsA

  Salesbot - B2B outreach LinkedIn MCP Server with CRM and emailA

  Synchronize one provider-safe page (at most 500) of the API-key owner's 1st-degree LinkedIn relations into the local workspace cache. This is a provider read, not a LinkedIn people search, and does not consume the search quota. The server persists continuation state and atomically enforces a 15–20 minute delay, four-page hourly cap, and twelve-page daily cap across UI and MCP. Respect RELATIONS_SYNC_PROTECTED retry_after_seconds before continuing.

• revoke_api_keyA

  FlexYield — blockchain RPC gatewayA

  Revoke one API key of your account by id; calls with that key stop working immediately and the key cannot be restored. Use it when a key leaked or a service is retired; ids come from list_api_keys. Not for pausing a key (set its budget to a small cap with configure_key instead) and not for the key you are calling with unless you hold another. Returns JSON: id, name, revoked_at. Idempotent. Needs your API key.

• get_planA

  kurdish-tts-sttA

  Show what this connection may use. With an API key: your current plan, remaining allowance, which model_versions and speaker ids you may render. Without a key: the purchasable plan ladder and how to get a key. Free, no credits consumed. Call this FIRST when any tool returns a 401 or 403 — it is the fastest way to learn what went wrong.

• get_my_strategiesA

  Sentinel AlephA

  Lists the saved strategies on the API key's account, newest first, archived ones included (active false): id, mode, engines, minimum confidence, direction and symbols. Use it to pick the strategy_id that run_backtest, update_strategy and delete_strategy take; for live bot activity use get_my_bots. Archived strategies count toward limit, and there is no paging: a strategy beyond the newest limit is read by its id with get_strategy; an account without strategies gets an empty list. An empty symbols list means any pair, so run_backtest then needs symbol. Needs an API key (without one the call is refused with 401) and spends 1 read unit of the daily quota; read only.

• demand.create_watchA

  iwant.fyi - shop, price-check and keep lookingA

  Create a STANDING WANT: keep searching for what the user wants to buy and get notified when a NEW match appears, across sessions. Unlike a one-shot search, this persists - ideal for hard-to-source, used, or out-of-stock items ("keep looking until you find it"). Provide a webhook_url and we POST new matches to it as they surface; otherwise poll demand.list_watches. Same query shape and enforced constraints as demand.search. WITHOUT AN API KEY this works too, under limits: no webhooks, three standing wants at a time, a six-hour minimum re-check, and a seven-day life. Any limit applied to your request comes back in `notes`.

• convert_documentA

  flatmarkA

  Convert a document up to 8 MB to Markdown and return it directly. Pass the file as base64 in `content_base64`, or as a download link in `file`, and its name in `filename`. The extension decides the type: .pdf, .docx, .pptx, .xlsx, .html, .htm or .txt. Returns `markdown` and `meta` (`filename`, `length` in characters). PDFs come back as plain text without headings and without OCR. For scans, tables and page numbers, use `submit_conversion_job`. Works without an API key at the anonymous rate limit. Credits: 1 per call.
