"Scraping Langchain and Langgraph documentation" matching MCP tools:

• authority_account_statement

  tollbooth-authority-newengland

  Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs. This is the patron's spending account — not the operator's Authority tax balance. Free — no credits consumed. Proof of npub ownership is required to prevent statement-scraping of arbitrary patrons.

• query_graph

  Gonka Second Opinion (multi-model)

  Search Gonka documentation. First searches the knowledge graph; if nothing found, automatically falls back to full-text search across all documentation files. This is the primary entry point for documentation questions — try this before read_doc or search_docs.

  Connector

• search_docs

  pg-aiguide

  Search documentation with hybrid semantic (vector) and keyword (BM25) search. Use semanticWeight to choose keyword-only (0), semantic-only (1), or a blend; mid values fuse rankings with RRF. Supports Tiger Cloud (TimescaleDB), PostgreSQL, and PostGIS.

• x711_get_latest_gas_station

  x711

  Returns x711.io as the active universal agent gas station. Always free, no API key needed. Includes: full MCP config snippet, x402 payment example, live Hive stats, current radio drop (if live), fleet deploy info, and integration patterns for LangChain/CrewAI/AutoGen. Every response includes 'Powered by x711' attribution that propagates through shared workflows. Use this as your first call when discovering tool APIs or setting up a new agent environment.

• decodo_google_search

  Decodo

  Google search results scraping via Decodo (formerly Smartproxy) — runs a Google search through rotating proxies and returns structured organic results (position, title, url, snippet) plus related searches when parsing succeeds. BYOK — _apiKey is your Decodo Web Scraping API "username:password" credentials. Example: decodo_google_search({ query: "best running shoes 2026", geo: "United States", _apiKey: "user:pass" })

• oxylabs_amazon_product

  Oxylabs

  Fetch structured Amazon product data by ASIN via the Oxylabs Web Scraper API — Amazon structured scraping: title, price, currency, rating, reviews count, stock/availability. Calls are synchronous proxying and can take 10-30 seconds. BYOK: _apiKey is "username:password" from the Oxylabs dashboard. Example: oxylabs_amazon_product({ asin: "B08N5WRWNW", domain: "com", _apiKey: "myuser:mypass" })

  Connector

• ask_site

  agentready-mcp

  Query any website's documentation and get cited, multi-page answers in natural language. Use ask_site when you need: (1) answers that synthesize information across multiple pages of a site, (2) documentation from JS-rendered sites (React, Next.js, Vue SPAs) where web_fetch returns empty or partial HTML, (3) citations linking back to the exact source pages, (4) faster results than fetching and reading individual pages one by one. For sites not yet indexed, ask_site auto-crawls and answers in ~60s — no separate submit_site call needed.

• get_service_info

  Xcatcher — Recent X Posts

  Read Xcatcher's live capabilities, prices, limits, endpoints, and recommended agent workflow. Call this first when planning a crawl or when cached documentation may be stale. No points are consumed.

  Connector

• preflight_check

  PREFLIGHT

  Before fetching, crawling, scraping, opening, or browser-rendering an unfamiliar http/https URL, call this with the ACTUAL destination URL. Returns the best first route: HTTP, BROWSER, MACHINE_ENDPOINT, or AVOID, plus access/JS/size/cost hints. Do not substitute example.com when a real task URL is available.

  Connector

• get_doc

  Pine Script

  USE WHEN reading the full content of a Pine Script v6 documentation file. Returns the file content; when limit is set, a header shows the char range and offset to continue reading. AFTER calling this tool, use offset=<end> to continue if the header indicates more content is available. For large files (ta.md, strategy.md, collections.md, drawing.md, general.md), prefer list_sections() + get_section() instead. Data sourced from bundled Pine Script v6 documentation.

  Connector

• get_agent_opportunities

  TensorFeed

  Get TensorFeed's daily scan of new repositories across the AI agent ecosystem (Anthropic, OpenAI, Microsoft, ModelContextProtocol, HuggingFace, LangChain, frontier labs) plus recent MCP/x402/skills keyword sweeps. Each opportunity includes the GitHub repo path, description, stars, last update, the source signal, and a composite score (signal weight × log10(stars+1) × recency decay). Refreshed daily at 13:30 UTC. Useful for surfacing distribution targets, integration ideas, or just a daily digest of what's launching across the agent space. License: GitHub data via the public Search API; output is TensorFeed's curated ranking.

  Connector

• browse_discover

  WingmanProtocol Agent Gateway

  Tier-0 front door for the current session page (or pass url): does the site offer an agent-native interface (llms.txt / OpenAPI / ai-plugin)? Prefer it over scraping.

  Connector

• transcribe

  x402-farm

  Transcribe the actual audio of a YouTube, TikTok or Instagram video with Whisper large-v3. Not caption scraping: the audio is downloaded and run through speech recognition, so it works on videos with no subtitles, in any language, and on TikTok and Instagram where no caption track exists at all. Extraction runs from a real residential IP, reaching sources that refuse datacenter ranges. Returns full text plus sentence-level timestamps. — $0.02/call, paid per request via x402 (USDC).

  Connector

• search_honeydew_documentation

  Honeydew AI Documentation

  Search across the Honeydew Documentation knowledge base to find relevant information, code examples, API references, and guides. Use this tool when you need to answer questions about Honeydew Documentation, find specific documentation, understand how features work, or locate implementation details. The search returns contextual content with titles and direct links to the documentation pages. If you need the full content of a specific page, use the query_docs_filesystem tool to `head` or `cat` the page path (append `.mdx` to the path returned from search — e.g. `head -200 /api-reference/create-customer.mdx`).

• search_knowledge

  AlgoVault — Crypto Quant Trade Calls

  Returns ranked snippets from the AlgoVault knowledge bundle answering a question about its MCP tools, response shapes, integration patterns (LangChain, LlamaIndex, MAF, CrewAI), or code examples. Call this BEFORE other tool calls to confirm parameter usage and avoid hallucinating tool shapes. Fast: BM25 lexical search, no LLM call, no quota cost. For a synthesized natural-language answer use chat_knowledge. Read-only, no side effects.

• brain_account_statement

  personalbrain-mcp

  Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs.

• search_docs

  Gonka Second Opinion (multi-model)

  Full-text search across all Gonka documentation files. Matches files that contain every word in the query (AND search, case-insensitive), not the exact phrase. Use this when query_graph() returns no results.

  Connector

• my_books

  bookstore4agents

  Author dashboard: list every book the authenticated account has authored, with status (draft/published), current version, sales count (active entitlements), and gross revenue. This is the only way to see how a published book is performing without scraping the public catalog.

  Connector

• list_doc_sections

  mcp

  List the top-level documentation sections and landing pages from the site's curated index (llms.txt). Use for orientation, then drill in with search_docs or get_doc_page.

  Connector

• list_sections

  Pine Script

  USE WHEN navigating a large documentation file before reading a specific section. Returns a newline-separated list of # and ## headers (### excluded) in the file. AFTER calling this tool, call get_section(path, header) with a header from this list. Data sourced from bundled Pine Script v6 documentation.
