"Using Perplexity for Internet Data Retrieval" matching MCP tools:

• openlibrary_search_insideA

  openlibrary-mcp-serverA

  Search the full text of books scanned by the Internet Archive — the "which book contains this passage?" lookup that the metadata tools cannot answer. Quote a phrase for an exact-phrase match; bare terms match anywhere in the text. Each result is an Internet Archive item with the matching passages as snippets, plus a relevance score. The full-text index is an order of magnitude slower than the metadata endpoints (seconds, not milliseconds), so reach for it when the passage is the question, not as a general book search — use openlibrary_search_books for title, author, or subject. Results key on Internet Archive items rather than Open Library works: chain the returned ia_identifier to archive.org, or match it against the ia_identifiers on openlibrary_search_books results to reach the catalogue record.

• find_examplesA

  SenzingA

  Find working SOURCE CODE examples from 42 indexed Senzing GitHub repositories. REQUIRED: either `query` (string, for search) or `repo` with `file_path` or `list_files=true` — the call WILL FAIL without one. Three modes: (1) Search: pass `query` to find examples across all repos, (2) File listing: pass `repo` + `list_files=true`, (3) File retrieval: pass `repo` + `file_path`. Indexes source code (.py, .java, .cs, .rs, .ts, .js) and READMEs — NOT build/data files. For sample data, use get_sample_data. Covers Python, Java, C# (official SDKs) plus Rust and TypeScript/Node.js (community-maintained wrappers, not official) SDK patterns: initialization, ingestion, search, redo, configuration, message queues, REST APIs. Use max_lines to limit large files. Returns GitHub raw URLs for file retrieval.

• post_perplexity_sonarA

  AIsa Web Search & ResearchA

  Ask a question and get a written answer with web citations, rather than a list of links to read yourself. Body is OpenAI chat-completions shaped: `model` (required, `sonar`) and `messages`. Returns `choices[0].message.content` as prose, plus `citations` (an array of URL strings) and `search_results[]` with `title`, `url`, `snippet`, `date` and `source`, and a `usage` block. Measured at about 3 seconds. Billed at a flat $0.012 per request. This is the cheapest and fastest of the four Perplexity endpoints — use it for a single factual question. Step up to `post_perplexity_sonar_pro` for multi-part questions, or `post_perplexity_sonar_reasoning_pro` when the answer requires working through steps. If you need results you can iterate over rather than prose, use `post_tavily_search`; `post_exa_answer` answers the same shape of question with semantic retrieval, at $0.08.

• extract_verifiedA

  US Company Intelligence for AI Agents (SEC EDGAR, x402)B

  Read a page and get a deterministic verdict on whether the retrieval can be trusted, with evidence. PRIVATE BETA. Verified browser-based web content retrieval for AI agents. Same retrieval as POST /v1/extract ($0.005), plus what an agent needs to trust the result without re-fetching it: declared block detection (HTTP status and blocking-page signatures), non-empty validation, content consistency checks against navigation-dominant and templated extractions, a retrieval timestamp, and evidence metadata including the final URL after redirects, character and word counts, and a sha256 checksum of the returned markdown. Every check is deterministic: no model runs in this path, so two calls on the same page return the same verification. Failed checks are DECLARED alongside the content, never hidden. This does not bypass CAPTCHA or authentication and makes no claim to defeat anti-bot systems: it detects blocking and says so. — $0.020012/call, paid per request via x402 (USDC). Use when asked: "read this page with proof", "was this page blocked", "verified page retrieval".

• search_esimA

  TripuckA

  Tripuck eSIM search — prepaid travel data plans (eSIM) for a destination country, compared across multiple providers. Use this when the user asks about mobile data, internet, SIM or eSIM for a trip, e.g. "eSIM for Japan", "data plan for my trip to the US", "internet in Dubai", "Japonya için eSIM", "خطة بيانات لدبي", "Datentarif für die Türkei". Input: a destination country (the LLM maps the place to its ISO country code), with optional minimum data (GB), validity days and sorting. Returns available packages with data amount, validity, coverage and price, each deep-linking to Tripuck.com for purchase. The LLM MUST infer the user language from the conversation and pass it via the `locale` parameter ("tr" Turkish, "en" English, "ar" Arabic, "az" Azerbaijani, "de" German, "ka" Georgian, "uz" Uzbek). All widget UI text and the text response are then returned in that language. If `currency` is not specified, a sensible default is picked from the locale (tr→TRY, en→USD, de→EUR, ar→USD, az→AZN, ka→GEL, uz→UZS).

• resolve_topicA

  Pine ScriptA

  USE WHEN looking up an exact Pine Script API term or known concept keyword. Returns the best-matching doc paths with matched keywords and a retrieval suggestion (get_doc or list_sections + get_section). AFTER calling this tool, follow the suggestion: call get_doc() for small files or list_sections() + get_section() for large files. For natural language questions use search_docs() instead. Data sourced from bundled TOPIC_MAP and doc file content scan.

  Agent Einstein — Crypto & Market IntelligenceA

  Real-time data retrieval and compute for any token, on any supported chain — bundles a live dual-model price forecast (Google TimesFM 3.0 + Kronos, with quantile confidence bands) at no separate charge. Unlike the free get_price_forecast this runs fresh inference and is not limited to four assets. Experimental research feature — not investment advice; use at your own risk. [Paid: $0.65 per call from your Einstein credit balance. Free alternatives exist for several of these — see list_einstein_capabilities.]

• cite42_searchA

  Cite42 AI Search Visibility TrackerA

  Run a query against AI models (ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews) and return each answer plus the sources it cited. Covers AI-search, citation, SEO, keyword, trend, and market-research data. If a plan needs more than 20 endpoint calls or may use more than $5 USD, estimate the cost in USD and ask the user before continuing. Quote Cite42 costs and balances in USD using cite42Billing or the USD pricing table. Legacy credit fields are for compatibility only. These funds belong to Cite42, not the host or model provider. AI visibility metrics include counts; quote them with percentages, not as a market-wide score. Optional recommendations are a separate paid call, never automatic. After a visibility result, offer recommendations using its requestId; run only when the user requests advice and knows the additional cost. Free: cite42_balance for the remaining balance, cite42_pricing for exact per-tool prices and cost estimates, cite42_usage for recent calls, spend, and limits. Pricing is per selected AI surface. Omitting models queries the three default surfaces (chatgpt, perplexity, gemini); fullSweep: true queries all five, adding claude and google_ai_overview at a higher cost. Use the models field when the user names a surface or asks to reduce spending, and call cite42_pricing for exact current rates.

• siteborne_retrieve_verified_web_contextA

  SITEBORNE Utility NetworkA

  Retrieve and verify evidence from one public web URL using direct HTTP retrieval. Use when: the request is specifically about the content and provenance of a URL. Do not use when: evidence must be synthesized for a company (use siteborne_build_company_evidence_graph), extracted from an authorized document (use siteborne_extract_document_evidence_json), checked against an existing output contract (use siteborne_verify_agent_output), or the page requires JavaScript rendering (rendered retrieval is not available). Parameters: retrieval_mode must be direct; rendered is defined but unavailable and is rejected before any payment challenge, never substituted with direct retrieval. output_mode structured needs buyer_schema and field_selectors to be meaningful; redirect_policy and max_redirects bound redirect following; max_content_size bounds returned bytes; maximum_authorized_price only constrains payment and never changes retrieval scope. Behavior: open-world: a paid request performs bounded outbound HTTP retrieval of the target URL through a safe-egress boundary (private and loopback destinations are refused) and persists governed payment, audit, job and Workflow state; an unpaid request returns payment_required; a repeated identical request with the same payment is replay-protected and is not charged twice. Retrieval admission follows the governed runtime rate policy; no fixed public per-origin rate is promised. This service is currently production-enabled. Economics: exact price of $0.008 USD per request in direct mode; the payment challenge requires that amount and the charge settles at exactly that amount. rendered mode has a governed price of $0.029 USD but is not available: it is rejected before any payment challenge and never substituted. Failure: schema-invalid input and unavailable modes are rejected before any payment challenge; target-site errors, timeouts and unavailable retrieval return a structured MCP error and are never answered with a substitute result. Returns: normalized, source-attributed web context with verification and PCC evidence.

• search_akashicA

  OpenAkashicB

  Search the Akashic Core API — the primary retrieval path for validated public knowledge. Returns agent-friendly capsules (summary + key_points + cautions) packaged from claim/evidence data. Use this FIRST for factual/conceptual questions. For your own working notes use search_notes. - mode='compact' → 1-sentence summary per capsule (smallest, best for small models) - mode='standard' → full capsule without metadata (default) - mode='full' → everything including metadata and timestamps - fields=['summary','key_points'] → custom projection overriding mode

• sequenceA

  EnsemblA

  "DNA / cDNA / CDS / protein sequence of [gene]" / "FASTA for [Ensembl ID]" / "get sequence of [transcript]" — sequence by Ensembl stable ID. Type defaults to "genomic"; pass "cdna", "cds", or "protein" for processed forms. Use for sequence retrieval in primer design, variant analysis, or downstream sequence tools.

• query_knowledgeA

  mcp-serverA

  Search the company's connected knowledge across every source — Drive, SharePoint, Confluence, Slack, Notion — with cited synthesized answers, lifecycle awareness, and refusal-on-weak-context. Returns a written answer with [n] citations plus the ranked source chunks. Modes: `fast` (1,500 kT — retrieval-only, no synthesis), `standard` (12,500 kT — default; synthesized answer over the top retrieval set), `deep` (25,000 kT — wider retrieval + premium synthesis for complex questions). Pick the cheapest tier that answers the question. Responses are capped at 25,000 output tokens per Claude Connectors policy; if truncated, structured metadata carries `truncated: true` and `query_id` so the agent can call `get_source_detail` for full provenance.
