Spicrawl MCP Server

The Spicrawl MCP server is a Model Context Protocol server that gives AI agents in Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, Gemini CLI and Codex web scraping to Markdown, structured data extraction, screenshots, browser sessions and batch scraping as 25 native tools.

Quickstart

1. Create an API key at app.spicrawl.com. Keys start with spicrawl_live_ or spicrawl_test_.

2. Connect the hosted endpoint, https://mcp.spicrawl.com/mcp (MCP Streamable HTTP, nothing to install):

   export SPICRAWL_API_KEY=spicrawl_live_...
   claude mcp add --transport http spicrawl https://mcp.spicrawl.com/mcp \
     --header "Authorization: Bearer $SPICRAWL_API_KEY"

   Codex: codex mcp add spicrawl --url https://mcp.spicrawl.com/mcp --bearer-token-env-var SPICRAWL_API_KEY

3. Or run it locally over stdio (Node.js 20+), for clients that only launch local servers:

   claude mcp add spicrawl --env SPICRAWL_API_KEY=$SPICRAWL_API_KEY -- npx -y @spicrawl/mcp

4. Ask your agent: "Use Spicrawl to read https://example.com/pricing as markdown and list each plan with its price." It calls spicrawl_scrape and gets the page back as Markdown.

Both transports serve the same 25 spicrawl_* tools, and every call runs under your key with the same scopes, limits and credits as a direct API call.

What it does

• Scrape any URL to Markdown, text, HTML, a JSON envelope or a printed PDF with one tool, spicrawl_scrape. Markdown is the default and strips the page to its main content.

• Render JavaScript with render: true (the obscura browser engine, 3 credits) or pin real Chromium with engine: "chromium" (8 credits). A plain fetch costs 1 credit, and mode: "auto" escalates fetch to browser and bills only the rung that worked (price table).

• Extract structured data with a CSS/XPath selector map (extract) or from the JSON-LD, OpenGraph, Twitter Card and microdata a page publishes (autoparse).

• Drive the page before capture with 8 typed browser actions: click, fill, wait_for, wait_for_navigation, scroll (including infinite scroll), select, evaluate and screenshot.

• Return screenshots and PDFs the model can see: screenshots arrive as MCP image blocks (up to 5 MB of base64 each) and printed pages as application/pdf resource blocks (up to 10 MB).

• Batch scrape thousands of URLs as one async job, up to 10,000 items per call, with 9 tools to submit, poll, page through results, retry, cancel and keep a job open for crawling.

• Keep a logged-in browser with persistent sessions: cookies, storage and a pinned engine reused across scrapes.

• Answer "what did that cost?" from usage and request-log tools, and read the Spicrawl docs from inside the agent.

Which tool to use

• If you need one page's content or data now, use spicrawl_scrape.

• If the page is blank or a skeleton without JavaScript, call spicrawl_scrape again with render: true.

• If you know the page's structure, use extract with CSS selectors; if you don't, try autoparse.

• If you have more than about 20 URLs, use spicrawl_batch_submit, then spicrawl_batch_status and spicrawl_batch_results.

• If you discover URLs as you go (crawling), submit with open: true, append with spicrawl_batch_add_items and finish with spicrawl_batch_close.

• If you must log in first, use spicrawl_session_create and pass its id as session_id to spicrawl_scrape.

• If a call failed and you need to know why, use spicrawl_request_get with the request id, or spicrawl_requests_list with only_errors.

• If you are unsure of a parameter or an error code, use spicrawl_docs_search before guessing.

Tools

25 tools, grouped by task. Tools reject unknown arguments, so a misspelt field fails with an error naming it instead of being silently dropped. Every tool sets a title and explicit readOnlyHint, destructiveHint and openWorldHint annotations, so a client knows which calls to confirm: spicrawl_scrape is not read-only (its method and actions can submit forms), and spicrawl_batch_cancel, spicrawl_session_release and spicrawl_session_delete are destructive. Full argument reference: docs.spicrawl.com/agents/mcp.

Coming soon

spicrawl_browser_connect_url will mint a single-use CDP WebSocket URL for driving a Spicrawl-hosted browser from Puppeteer or Playwright; remote browsers are not available yet. The schemas also accept ai_extract, stealth, extract_preset, premium_proxy, proxy_country and sticky_key ahead of launch. Agents should not send them yet. To list only what works today, set SPICRAWL_MCP_HIDE_UNAVAILABLE=1 (see Environment variables).

Example prompts

• "Scrape https://example.com/pricing as markdown and summarise the plans."

• "Get the product name, price and stock status from this URL." (spicrawl_scrape with extract or autoparse)

• "Take a full-page screenshot of https://example.com after the cookie banner is gone." (render, actions, screenshot_fullpage)

• "Scrape these 500 URLs and give me each page title." (spicrawl_batch_submit, then spicrawl_batch_results)

• "Why did my last scrape fail?" (spicrawl_requests_list with only_errors, then spicrawl_request_get)

• "How many credits have I used this month?" (spicrawl_usage_summary)

Set up your MCP client

Put your key in SPICRAWL_API_KEY and reference it from the config where the client allows, so the key never lands in a committed file.

Hosted endpoint, stored for you only (add --scope user for every project):

claude mcp add --transport http spicrawl https://mcp.spicrawl.com/mcp \
  --header "Authorization: Bearer $SPICRAWL_API_KEY"

To share it with a team, commit .mcp.json at the project root. Claude Code expands ${VAR}, so each teammate's own key is used:

{
  "mcpServers": {
    "spicrawl": {
      "type": "http",
      "url": "https://mcp.spicrawl.com/mcp",
      "headers": { "Authorization": "Bearer ${SPICRAWL_API_KEY}" }
    }
  }
}

Or install the plugin, which bundles the MCP server and the Spicrawl agent skill:

claude plugin marketplace add OfficialSpicrawl/agent-plugins
claude plugin install spicrawl@spicrawl-plugins

Check with claude mcp list, or /mcp in a session. More: docs.spicrawl.com/agents/claude-code.

Claude Desktop's claude_desktop_config.json starts local (stdio) servers only, and custom connectors cannot send an Authorization header, so run the package locally. The file is at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS and %APPDATA%\Claude\claude_desktop_config.json on Windows:

{
  "mcpServers": {
    "spicrawl": {
      "command": "npx",
      "args": ["-y", "@spicrawl/mcp"],
      "env": { "SPICRAWL_API_KEY": "spicrawl_live_..." }
    }
  }
}

Restart Claude Desktop after saving.

Use the Add to Cursor button above, or add this to .cursor/mcp.json in the project (or ~/.cursor/mcp.json for every project). Cursor resolves ${env:NAME} in url and headers, so start Cursor from an environment where SPICRAWL_API_KEY is set:

{
  "mcpServers": {
    "spicrawl": {
      "url": "https://mcp.spicrawl.com/mcp",
      "headers": { "Authorization": "Bearer ${env:SPICRAWL_API_KEY}" }
    }
  }
}

More: docs.spicrawl.com/agents/cursor.

Use the Install in VS Code button above, or add this to .vscode/mcp.json. VS Code uses the servers key, and the input variable makes it ask for the key once and store it securely, so the file is safe to commit:

{
  "inputs": [
    { "type": "promptString", "id": "spicrawl-api-key", "description": "Spicrawl API key", "password": true }
  ],
  "servers": {
    "spicrawl": {
      "type": "http",
      "url": "https://mcp.spicrawl.com/mcp",
      "headers": { "Authorization": "Bearer ${input:spicrawl-api-key}" }
    }
  }
}

VS Code does not expand ${env:...} inside headers, so use the input variable. More: docs.spicrawl.com/agents/github-copilot.

Windsurf is now named Devin Desktop. For the default Devin Local agent, add the server in local scope (saved to the gitignored .devin/mcp_config.local.json):

devin mcp add spicrawl https://mcp.spicrawl.com/mcp -H "Authorization: Bearer $SPICRAWL_API_KEY"

For the legacy Cascade agent, edit ~/.config/devin/mcp_config.json (%APPDATA%\devin\mcp_config.json on Windows). Cascade reads the URL from serverUrl and replaces ${env:...}:

{
  "mcpServers": {
    "spicrawl": {
      "serverUrl": "https://mcp.spicrawl.com/mcp",
      "headers": { "Authorization": "Bearer ${env:SPICRAWL_API_KEY}" }
    }
  }
}

More: docs.spicrawl.com/agents/windsurf.

Gemini CLI strips variables whose names contain KEY, TOKEN or AUTH before expanding headers, so export the key under another name:

export SPICRAWL_MCP_BEARER="$SPICRAWL_API_KEY"

Then add to ~/.gemini/settings.json (or .gemini/settings.json for one project). Streamable HTTP uses the httpUrl key:

{
  "mcpServers": {
    "spicrawl": {
      "httpUrl": "https://mcp.spicrawl.com/mcp",
      "headers": { "Authorization": "Bearer $SPICRAWL_MCP_BEARER" }
    }
  }
}

Or: gemini mcp add --scope user --transport http --header 'Authorization: Bearer $SPICRAWL_MCP_BEARER' spicrawl https://mcp.spicrawl.com/mcp. Run /mcp to check. More: docs.spicrawl.com/agents/gemini-cli.

Codex reads the key from the environment each time it connects, so the key never lands in a file:

codex mcp add spicrawl --url https://mcp.spicrawl.com/mcp --bearer-token-env-var SPICRAWL_API_KEY

The equivalent ~/.codex/config.toml (or .codex/config.toml in a trusted project):

[mcp_servers.spicrawl]
url = "https://mcp.spicrawl.com/mcp"
bearer_token_env_var = "SPICRAWL_API_KEY"

Local stdio instead:

[mcp_servers.spicrawl]
command = "npx"
args = ["-y", "@spicrawl/mcp"]
env = { SPICRAWL_API_KEY = "spicrawl_live_..." }

More: docs.spicrawl.com/agents/codex.

A stdio-only client runs npx -y @spicrawl/mcp with SPICRAWL_API_KEY in its environment. The server accepts API keys only, not OAuth. Setup pages for more clients (OpenCode, Zed, JetBrains, Cline, Goose and others): docs.spicrawl.com/agents/mcp.

Environment variables

With no docs variable set, a server pointed at a self-hosted API reads that API's own docs at <SPICRAWL_PUBLIC_BASE_URL or SPICRAWL_BASE_URL>/docs.

Self-host the MCP server over HTTP

The hosted endpoint runs this package's Streamable HTTP server. To run your own:

SPICRAWL_MCP_ADDR=127.0.0.1:8090 \
SPICRAWL_BASE_URL=https://api.spicrawl.com \
npx -y @spicrawl/mcp --http

• SPICRAWL_BASE_URL defaults to http://127.0.0.1:8080 in HTTP mode (a Spicrawl API on the same host), not to the public API. Set it to https://api.spicrawl.com to front the public API.

• MCP is served at POST/GET/DELETE /mcp; liveness at GET /healthz (no auth).

• Each caller sends their own key as Authorization: Bearer spicrawl_live_.... The key is checked against the API before a session opens (401 if refused, 503 with Retry-After if the API cannot be reached), and a session is pinned to the key that opened it.

• The server speaks plain HTTP. Put it behind TLS before sending keys across a network.

ChatGPT endpoint (OAuth)

The same process can serve a second, restricted MCP endpoint for ChatGPT apps. It is off unless SPICRAWL_CHATGPT_ENABLED is on, and /mcp is unchanged either way.

Authentication takes OAuth access tokens (spicrawl_oat_…) only:

• No token: 401 with WWW-Authenticate: Bearer resource_metadata="https://mcp.spicrawl.com/.well-known/oauth-protected-resource/chatgpt/mcp", scope="scrape batch".

• A bad, inactive, expired or wrong-audience token, or an API key (spicrawl_live_…/spicrawl_test_…, never accepted here): the same 401 plus error="invalid_token", error_description="…".

• A tool call the token's scopes do not cover: 403 with error="insufficient_scope". spicrawl_scrape needs scrape, the batch tools need batch, the docs tools need only a valid token.

• The authorization server unreachable or refusing this server's secret: 503 with Retry-After.

Each token is checked with POST <issuer>/api/oauth/introspect (Authorization: Bearer <SPICRAWL_OAUTH_INTROSPECT_SECRET>, form body token=…). Only active: true with aud equal to the resource is accepted. A positive answer is cached by the token's SHA-256 for at most 30 seconds and never past its exp. Tools run upstream under the api_key the introspection returns; neither it nor the token is logged. If the API refuses that key mid-call, the tool returns an error whose _meta["mcp/www_authenticate"] carries a fresh invalid_token challenge, and the token is dropped from the cache.

The endpoint lists six tools, each with explicit readOnlyHint/destructiveHint/openWorldHint, a title, and securitySchemes: [{type: "oauth2", scopes: [...]}] (also in _meta.securitySchemes):

spicrawl_scrape is read-only here, unlike on /mcp: this endpoint only sends a GET, with no method, body, headers or actions. spicrawl_batch_submit is not read-only, because it creates a job.

spicrawl_batch_results fills in the content of a succeeded item that the results page lists without it, which happens while the job is still finishing, from GET /v1/batch/{id}/tasks/{seq}/content. It fetches at most 25 items and 2 MiB per page. An item that can't be read yet comes back unavailable, and one past the size cap omitted.

Every other argument is refused, not dropped. Results keep the content, the site's status and the credits charged; request ids, timestamps, engine and proxy details, storage references and project ids are left out.

Installed globally (npm install -g @spicrawl/mcp), the command is spicrawl-mcp (alias spicrawl-mcp-server), with --http, --version and --help.

FAQ

Is there a hosted Spicrawl MCP server?

Yes: https://mcp.spicrawl.com/mcp, MCP Streamable HTTP, authenticated with Authorization: Bearer <API key>, so there is nothing to install.

Is Spicrawl free?

Spicrawl bills credits per successful request, and during the beta every organization gets one plan of 1,000 credits per month. Failed requests cost 0 credits; a cache hit is billed at the same price as the fetch that stored it. See Credits.

Does it render JavaScript?

Yes. Set render: true on spicrawl_scrape to run the page in a browser, or mode: "auto" to let Spicrawl escalate from a plain fetch only when needed.

Does it work with Claude Code, Cursor and VS Code?

Yes, and with Claude Desktop, Windsurf, Gemini CLI, Codex and any client that speaks MCP Streamable HTTP with custom headers or launches stdio servers.

Can it crawl a whole website?

There is no single crawl tool. Scrape a page with links: true to get its links, then feed them to an open batch job (open: true and spicrawl_batch_add_items).

Does it support OAuth?

Not on /mcp: it accepts Spicrawl API keys only, so turn OAuth off for it in clients that try it on a 401. The separate ChatGPT endpoint at /chatgpt/mcp takes OAuth access tokens only, when the operator turns it on.

Should I use the MCP server, the SDK or the CLI?

Use the MCP server when an AI agent should call Spicrawl as tools. Use @spicrawl/sdk in your own TypeScript or JavaScript code, @spicrawl/cli in a terminal or shell script, and the REST API from any other language.

Troubleshooting

curl -i https://mcp.spicrawl.com/mcp without a key answers 401: the endpoint is reachable.
