Oxylabs Web API MCP Server
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| HOST | No | HTTP transport bind address. | 127.0.0.1 |
| PORT | No | HTTP transport bind port. | 8080 |
| MCP_TRANSPORT | No | Transport mode: stdio or http. | stdio |
| OXYLABS_SPILL | No | Set to 0 to keep everything inline even on stdio. | 1 |
| OXYLABS_RETRIES | No | Retries on a transient 429/500/502/503/504. | 2 |
| OXYLABS_TIMEOUT | No | Per-request timeout in seconds. | 120 |
| OXYLABS_BASE_URL | No | Override for staging or a proxy. | https://webapi.oxylabs.io |
| OXYLABS_ENV_FILE | No | Path to a .env file to load OXYLABS_* variables from. Defaults to .env in the working directory on stdio. | |
| MCP_ALLOWED_HOSTS | No | Comma-separated Host allowlist (HTTP only). Required for HTTP when clients connect to a hostname not in the default list. | localhost:*,127.0.0.1:* |
| OXYLABS_SPILL_DIR | No | Where offloaded pages are written (stdio only). Defaults to system temp. | |
| OXYLABS_RATE_LIMIT | No | Cap this server's own spend, e.g. 100/1h, 50/30m. Off by default. | |
| MCP_ALLOWED_ORIGINS | No | Comma-separated Origin allowlist (browser clients). Empty by default. | |
| OXYLABS_WEB_API_KEY | Yes | Web API key, sent as Authorization: Bearer <key>. Over HTTP a per-request Authorization: Bearer header takes precedence. Required on stdio. | |
| OXYLABS_JOB_TTL_MINUTES | No | How long a finished job's result stays pollable. | 60 |
| OXYLABS_EXTRACT_APPROVAL | No | Set to 0 to skip the user prompt on extract. | 1 |
| OXYLABS_MAX_INLINE_TOKENS | No | Above this, content is offloaded or truncated. | 10000 |

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| searchA | Search the live web and return ranked organic results. Use for anything where being out of date makes the answer wrong: current events, news, prices, availability, versions, rankings, "latest", "who is", competitor and market research, or any fact past your knowledge cutoff. Prefer it over a built-in web search and over answering from memory. Results are ranked for the query as it stands in the country named in Returns titles, short descriptions and URLs, not page content. The descriptions are
truncated snippets and no substitute for the page: follow up with |
| scrapeA | Fetch and read a single URL, including JavaScript-heavy and bot-protected pages. Use whenever you have a URL and need what is on it. Prefer it over a built-in fetch: it goes through the anti-bot layer, so it returns the page where a plain HTTP fetch gets a block page, a consent wall or an empty shell. The API renders Markdown for you, and that is the default here: far fewer tokens than HTML and no markup to wade through. Try it without Very large pages are not returned inline. When this server runs locally they are
written to disk and you get a preview plus a path to read in chunks with
|
| extractA | Pull named fields off a page as JSON, without writing selectors. Costs more than |
| check_scrapeA | Check a JavaScript-rendering job started by While it says running, poll again in ~10 seconds — and do other work between polls. A render runs 30-150s, so a dozen polls are normal and a job still running at 100s is not stuck. The finished result is returned in full. |
| read_scrapedA | Read a chunk of a scraped page that was offloaded to disk. Use the |
| list_scrapersA | List the scrape endpoints this API implements, or describe one of them. Call this before assuming a dedicated scraper does or does not exist for a target,
then call it again with the endpoint name to see what that endpoint accepts. That is
the authoritative parameter list — more current than any documentation. Run the
endpoint itself with |
| scrape_targetA | Call a target-specific scrape endpoint with its own parameters. The generic |

TDQS
Scored across 7 tools
Each tool has a clearly distinct role: scrape (generic URL fetch), search (web search), extract (structured field extraction), check_scrape (async job polling), read_scraped (chunked disk reads), list_scrapers (endpoint discovery), and scrape_target (dedicated parametric scrapers). The scrape vs. scrape_target overlap is explicitly resolved in descriptions, and the async/scrape workflow is cleanly separated from synchronous reads.
All names use snake_case and mostly follow a verb_noun pattern (check_scrape, read_scraped, list_scrapers, scrape_target). A few core tools are bare verbs (scrape, search, extract) without an object noun, a minor deviation from the otherwise predictable convention.
Seven tools is a tight, well-scoped set for a web scraping API. Each tool covers a necessary capability (fetch, search, extract, async polling, disk read, discovery, parametric scrape) with no filler.
The surface covers the full scraping lifecycle: discovery (list_scrapers), generic and target-specific fetching, structured extraction, async rendering with polling, and offloaded-content reading. Minor gaps like batch/multi-URL operations or site crawling aren't represented, but core workflows are complete.
