• get_healthA

  my quant doesn’t speak english — editorial discoveryA

  Check that this endpoint responds with product.health.v1 metadata: product, API/MCP versions, deployed source SHA when available, and checked_at. Use for connection and version diagnosis; it does not fetch the editorial feed or prove source freshness. Public and read-only; no credentials or arguments. Use list_capabilities for supported surfaces and content limits.

• biorxiv_list_recentA

  biorxiv-mcp-serverA

  List preprints posted or revised within a date interval, optionally scoped to one server or a subject category. Returns 30 preprints per page (fixed by the API); pass `cursor` as an integer offset (0, 30, 60, …) to step through additional pages. Abstracts are omitted by default to keep the page small — pass include_abstract: true for the whole page, or call biorxiv_get_preprint (up to 10 DOIs per call) for a few. When server="both" (default), per-server pagination state is returned separately — use each server's `cursor` field for independent advancement. One server failing under server="both" does not abort the call: the other server's page is still returned and the failed one is named in `failed[]`, marking the result set as partial rather than complete. Every attempted server failing is a different case and does abort the call, with a retryable upstream_unavailable (or rate_limited) error — an empty page would otherwise be indistinguishable from an interval that genuinely holds nothing. Call biorxiv_list_categories for valid category strings; a server that answers a category filter with its unfiltered listing is left out with a notice, and invalid_category is raised when no server applied it. `funder` limits the listing to bioRxiv preprints funded by that organization, given its ROR ID; an ID api.biorxiv.org has no funder record for raises invalid_funder rather than returning an empty page.

• feedbackA

  Media Generator — Images, Videos & AudiosA

  Save user feedback to the MultipleWords feedback API (POST /api/feedback). Call this only when a result has feedback_prompt.ready=true (the server asks after every 3 MCP runs — not per tool — and keeps asking until saved). Ask the user to pick a reaction and show the emojis: 😍 excellent, 😊 good, 😐 average, 😞 bad. Pass `reaction` (excellent|good|average|bad, or the emoji) and optional `feedback` comment text. If the user does not add a comment, omit `feedback` — the server stores the MCP name saifs_ai. After it is saved, wait for 3 more MCP uses. Do not invent a reaction. Do not send user_name, email, is_login, or app_id — those are injected server-side from the authenticated session. When showing the saved reaction, include the matching emoji. Args: reaction: User reaction. One of excellent, good, average, bad, or the matching emoji: 😍 excellent, 😊 good, 😐 average, 😞 bad. feedback: Optional short comment from the user. If the user does not add a comment, leave this empty. The server then stores the MCP name saifs_ai. Do not send the generation result or the user's question here.

• public_booking_createA

  Coordinalo — Service Business OperationsB

  Create a public booking request. Does NOT require an API key, but DOES require: (1) requester identity — fullName plus at least email or phone, (2) submission context — channel and whether an agent assisted, (3) authorization.humanIntentConfirmed must be true. The booking is created as pending_confirmation — use public_booking_confirm with the returned confirmationToken to confirm. A bookingToken is also returned for future lifecycle management (cancel, reschedule). Rate-limited per IP+org. All requests are audited with semantic decision codes. Use public_service_list → public_availability_get_slots → public_booking_create → public_booking_confirm as the complete public booking flow.

• fvs_download_final_videoA

  Future Video StudioA

  Download a completed Future Video Studio final render URL to a local file. Use this only after fvs_get_render_status or fvs_get_paid_render_status returns a final_video_url for a completed render. The tool performs an unauthenticated HTTPS GET to that signed URL and writes the response bytes to output_path on the MCP server's local filesystem. It does not call the FVS Agent API, spend wallet credits, require FVS_AGENT_API_KEY, cancel jobs, or modify remote render state. Side effects and constraints: output_path is a local filesystem path for the MCP server process, parent directories are created, existing files are not replaced unless overwrite is true, and large videos may take minutes to download. The request timeout is 600 seconds. Use a fresh status check to refresh expired signed URLs, and do not pass arbitrary or untrusted URLs.

• pingA

  Nordic Financial MCPA

  Connectivity check that confirms the Nordic MCP server process is responding. Use this at the start of a session to verify the server is reachable before making other calls. Do not use as a proxy for database health — the server can respond while the Qdrant vector database is temporarily unavailable. To confirm data availability, call search_filings directly. Returns: A greeting string: "Hello {name}! Nordic MCP server is running."

• create_publisherA

  Lulu Ads — Publisher ConciergeA

  Start publisher registration (requires the human's consent — registers their email). Pass server_url (the MCP server's own URL or repo link) when known — it drives the "server URL set" step on the publisher's dashboard, skipping it leaves that step looking incomplete even once real traffic flows. Emails a 6-digit verification code to contact_email; ask the human for the code, then call confirm_publisher(pending_id, code) to receive the API key. This tool does NOT return a publisher_id or api_key — only confirm_publisher does.

  ConnectorNo auth

• check_connectionA

  FundingLandscapeA

  Verify MCP server connectivity. Returns success immediately with no database calls. Use this FIRST if experiencing tool errors - a successful response confirms the server is reachable. It does not confirm account, search, or paid-feature authentication, which can still return "Auth required" separately. Does not count toward your monthly searches.

• create_lead_listA

  MisarReach MCP ServerA

  Create a new, empty lead list in Hunter.io. Creating the list does not put anything in it, and it does not import anything locally — sync_lead_list does that. Call list_lead_lists first: each call creates a NEW list and nothing deduplicates by name. Requires an API key and a connected Hunter.io account. Costs no credits. Returns the created list with the id that sync_lead_list needs.

• sync_linkedin_connectionsA

  LinkedIn MCP Server (Salesbot)A

  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.

  Marketing Intelligence & OptimizationA

  Save user feedback to the MultipleWords feedback API (POST /api/feedback). Call this only when a marketing_intelligence or marketing_intelligence_get_engine result has feedback_prompt.ready=true (the server asks after every 3 MCP runs — not per tool — and keeps asking until saved). Ask the user to pick a reaction and show the emojis: 😍 excellent, 😊 good, 😐 average, 😞 bad. Pass `reaction` (excellent|good|average|bad, or the emoji) and optional `feedback` comment text. If the user does not add a comment, omit `feedback` — the server stores the MCP name marketing_analysis. Do not send the analysis, test notes, or the user's question as the comment. Ask on the 3rd, 6th, 9th, … MCP run. Do not invent a reaction. Do not send user_name, email, is_login, or app_id — those are injected server-side from the authenticated session. When showing the saved reaction, include the matching emoji. When to call this tool: - User picks a reaction on the 3rd, 6th, 9th, … time this MCP is used - Collect a short comment plus 😍 😊 😐 😞 after an analysis - Save how the marketing analysis felt (excellent/good/average/bad) When NOT to call this tool: - Calling feedback before this MCP has been used 3 times - Asking after every tool call instead of every 3rd MCP run - Inventing a reaction the user did not choose - Passing user_name, email, is_login, or app_id (server injects them)

• call_paid_apiA

  EntRouteA

  Call a previously discovered API endpoint. Use this after discover_paid_api to execute the request. IMPORTANT: You must first use discover_paid_api to find an endpoint. Then use the endpoint_id from the discovery result. Use the sample_request from the discovery result as your body template — it shows the exact parameter names the endpoint expects. Replace the example values with the actual values you need. Payment: this hosted server holds no wallet, so it cannot settle x402 payments. Free endpoints return their data directly. Paid endpoints return the payment challenge (amount, recipient, network) without charging anything. To pay automatically, run the local server instead: npx @entroute/mcp-server with EVM_PRIVATE_KEY set. Trust & safety: - EntRoute verifies that endpoints return valid 402 responses every 10 minutes, but does not guarantee response quality or accuracy. Treat results like any third-party API. - Prefer endpoints with high success rates (>95%) and recent verification timestamps.

• server_infoA

  HackMyIP — no-key IP intelligenceA

  Describe this MCP server: what it wraps, the fact that it is completely free with no API key, no signup and no auth, the fair-use rate limit, the full tool list, and links to hackmyip.com and its API docs. Call this when the user asks what this server can do, whether it costs anything, or where the data comes from.

• uis_get_dataA

  UNESCO UIS — Education, Science & Culture Statistics (provenance-first)A

  Statistical records from the UNESCO Institute for Statistics Data API, filtered by indicator codes (from uis_search_indicators, up to 25), geo unit codes (from uis_list_geo_units) and year range. Set include_footnotes for per-record source notes. Returns raw UIS records only — it does not aggregate, convert or otherwise transform values; ILO labour statistics live in the sibling ILOSTAT MCP server. Broad queries are rejected with the record count — narrow by geo unit or years. A code that does not exist is an error carrying the UIS API's own wording, never an empty result: zero rows means the codes are real and the selection has no data, and the hint then relays what the UIS reported (including the indicator's available year range). When only SOME of the requested codes exist, the matching rows are returned with `warnings` naming the rest.

• parlayapi_signupA

  ParlayAPIA

  Create a free-tier ParlayAPI account for the given email. Returns the API key, a magic-login URL the user can click to access their dashboard, and a Stripe upgrade URL. Idempotent: if the email already has an account, returns exists=true with the login URL only (the existing API key is intentionally NOT exposed for security). Use this when a user wants to start building with ParlayAPI and does not have a key yet. After signup, ask the user to add the returned api_key to their MCP server config under PARLAYAPI_KEY, then restart the MCP client to pick it up. Args: email: User's email address. intended_use: Optional one-line description of what they're building. Used for analytics. agent_id: Identifier for the agent making the call. Defaults to "mcp-client".

• dns_check_spfA

  DMARKOFF — DMARC, SPF & DKIM AnalyticsA

  Live SPF DNS lookup — queries DNS in real time and returns the SPF record, DNS-lookup count, parsed include tree, TXT diagnostics, errors and warnings. Does NOT require a project — works for any domain, even ones not monitored. Use this to verify SPF configuration, diagnose "too many DNS lookups" issues, or check a domain before adding it to a project.

• strale_pingA

  Strale - 290+ API capabilities for AI agentsA

  Checks that the Strale API is reachable and the MCP server is running. Call this before a series of capability executions to verify connectivity, or when troubleshooting connection issues. Returns server status, version, tool count, capability count, solution count, and a timestamp. No API key required.

  ConnectorNo auth

• signupA

  UnphurlA

  Create a new Unphurl account. Returns an API key (shown once, store it securely). After signup, the user must check their email and click the verification link. The API key won't work for URL checks until the email is verified. Verification link expires after 24 hours. If the link expires, use the "resend_verification" tool to request a new one. The account starts with 20 free pipeline check credits so the user can test with real URLs. Known domain lookups (google.com, github.com, etc.) and cached domain lookups are always free. To check more unknown domains through the full analysis pipeline, the user can purchase credits via the "purchase" tool. Once the user has their API key, they need to add it to their MCP server configuration as UNPHURL_API_KEY. This tool does not require an API key.

• show_defaultsA

  UnphurlA

  Show all 25 scoring signals with their default weights and descriptions. This is the baseline scoring that applies when no custom profile is specified. Use this to understand what each signal means and how much it contributes to the score before creating custom profiles. Profiles are sparse overrides on top of these defaults. This tool does not require an API key. The defaults are hardcoded and always available.

• pingA

  FXMacroDataA

  Quick health check that confirms the FXMacroData API and MCP server are reachable. Use this only if other tools fail unexpectedly — it is not needed before normal calls.
