Live fetch LinkedIn profile. USE THIS WHEN: - Live fetch LinkedIn profile. - Returns an enriched profile with details (work experience, education, skills, location, etc.) for a given LinkedIn profile identifier. **Note:** This endpoint does NOT return emails or phone numbers. To retrieve a person's contact details (emails and phone numbers), use the `POST /contact-details/single` endpoint (synchronous, recommended) or the `POST /individual-reveal/start` + `POST /individual-reveal/poll` pair (asynchronous). These can be found under the **Contact details** section. - Fetch fresh upstream profile/company/activity data.

Optional parameters: - getHistoricalHeadcount (boolean): Whether to compute the company's overall employee count over time and recent growth trends. This returns total headcount through time, not a per-department breakdown — for per-department headcount, use the Depth Chart endpoints. No additional cost, but may take longer. RETURNS: Response object with keys: output, chargeInfo, warnings, advicegetQuickstartScript_toolOperationId: getQuickstartScript. Get quickstart install script. USE THIS WHEN: - Get quickstart install script. - Returns a bash script that signs up for a Fiber API trial and prints your API key. - Start an asynchronous workflow, then call the related poll/status endpoint.

Attach card to trial account. USE THIS WHEN: - Attach card to trial account. - Attach a payment card to a cardless trial organization using a single-use Stripe shared payment token. The card is verified with a temporary $1 authorization that is refunded immediately (net cost $0), and the organization's free-credit ceiling is raised. The verified card is not saved for future charges — every future paid top-up requires a freshly-minted shared payment token. - Inspect or manage account-level billing and usage settings. EXAMPLE: Input: cardsAttach_tool(sharedPaymentGrantedToken="example_string") INPUT SCHEMA: Required parameters: - sharedPaymentGrantedToken (string): Single-use Stripe shared payment token (`spt_...`) authorizing exactly one card handoff. Mint it on the buyer side (see https://docs.stripe.com/agentic-commerce/concepts/shared-payment-tokens); each request must submit a freshly-minted token.

USE THIS WHEN: - List API keys. - List all API keys for your organization, including each key's name, prefix, expiration, and per-key credit usage. The secret value of a key is only shown once at creation and is never returned here. First-time users: create your initial API key at https://app.fiber.ai or via POST /v1/account/send-otp + verify-otp. This endpoint manages keys once you have one. EXAMPLE: Input: getAllApiKeys_tool(includeRevoked=True) INPUT SCHEMA: Required parameters: Optional parameters: - includeRevoked (boolean): Include revoked keys in the results. Defaults to false, returning only active keys. RETURNS: Response object with keys: output, chargeInfo, warnings, advice

searxng_web_searchSearches the web using SearXNG and returns a list of results, each with a title, URL, and content snippet. CRITICAL: The required parameter name is exactly `query` (not `prompt`, `q`, or any other name). Calls an external SearXNG instance; availability depends on the `SEARXNG_URL` configuration. Use `pageno` to paginate results; combine `time_range` and `language` to narrow scope. When `engines` and `time_range` are both provided, every selected engine must explicitly advertise time-range support via SearXNG /config; otherwise the request is rejected before search. To read the full text of a result URL, follow up with `web_url_read`.searxng_search_suggestionsReturns autocomplete suggestions from the configured SearXNG instance. Use this to refine vague or partial queries before searching.searxng_instance_infoDiscovers capabilities from all reachable configured SearXNG instances via /config, including categories.common/available, engines.common/available, defaults, locales, and plugins.web_url_readFetches a URL and returns readable content as markdown. Content-type aware: HTML is converted to markdown; JSON is pretty-printed; plain text, YAML, TOML, and XML are returned as fenced readable text. PDF text extraction is supported with bounded input, output, page count, time, concurrency, and memory; OCR is not supported. Binary, media, archive, and octet-stream downloads other than PDFs are intentionally rejected instead of being returned as raw bytes. When the operator configures browser solvers, mcp-searxng attempts FlareSolverr first and then Byparr only after a busy or transient-unavailable acquisition; cache hits bypass acquisition and a final busy or unavailable provider uses one uncached direct-fetch fallback. Three modes: (1) Full content — omit filtering params; use `startChar`/`maxLength` to paginate large pages. (2) Section extraction — set `section` to return content under a specific heading. (3) Headings only — set `readHeadings: true` to list all headings (mutually exclusive with other filtering params). Returns an error string if the URL is unreachable or content cannot be extracted. Use after `searxng_web_search` to read the full content of individual result URLs.

Frequently asked questions
Fiber AI is categorized under Search & Data Extraction and uses a remote HTTP/SSE transport. MCP SearXNG belongs to Search & Data Extraction and uses a local stdio subprocess. Pick Fiber AI for search & data extraction work and MCP SearXNG for search & data extraction.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Fiber AI is bring-your-own-key: usage is billed by the API provider you supply a key for. Auth: api key required. MCP SearXNG is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add fiber-ai and ihor-sokoliuk-mcp-searxng as separate keys in the same mcpServers object, and your assistant will call tools from either one.
