"A free research browser tool using Exa for local hosting with no limitations" matching MCP tools:

• check_free_tier_status

  TensorFeed

  Check the caller IP's free premium-API trial quota. TensorFeed gives 100 free /api/premium/* calls per IP per 24h rolling window with no auth required. This tool returns used_today, remaining, and resets_at without consuming a quota slot. Use it before deciding whether to make a paid call versus waiting for the trial reset. No arguments.

• send_fax

  SendThisFax

  Submit an uploaded PDF for faxing. Step 1 (before this tool): upload the PDF over plain HTTP multipart, using any HTTP client you have — shell, JavaScript fetch with FormData, Python, etc.: curl -F "file=@document.pdf" https://www.sendthisfax.com/api/upload fetch("https://www.sendthisfax.com/api/upload", {method: "POST", body: formDataWithFile}) The response contains fax_public_id and page_count. PDFs must be unencrypted, at most 50 MB and 1000 pages. Step 2: call this tool with the fax_public_id and the recipient fax number. Two modes: - With an API key (Authorization: Bearer stf_live_... on this MCP connection): the fax price is debited from the prepaid credit balance and sending starts immediately — no checkout, no browser. sender_email and billing_country are optional (they default to the key's records). Buy credits at https://www.sendthisfax.com/en/credits. - Without an API key: sender_email and billing_country are REQUIRED and the tool returns a checkout_url the USER must pay in a browser; the fax is sent automatically once paid. In both modes, poll get_fax_status until status reaches "delivered" or "failed" (failures after payment are auto-refunded). For integration testing, +19898989898 is the designated test recipient number.

• get_market_research

  skipseek

  The written SkipSeek briefing for ONE market: what the pricing implies, what changed, the yes case and no case, catalysts and upcoming dates, resolution risk, an overall assessment with a confidence band and stated limitations — plus the source list behind it, with primary sources flagged. USE WHEN you need reasoning and citations rather than numbers, e.g. "why is this priced at 34%" or "what would move this". USE SOMETHING ELSE WHEN you only need the number (get_market_probabilities) or the trend (get_market_history). Read-only. Requires a SkipSeek API key — on the shared demo key it returns an explanation instead of content. Research is generated per market and published selectively, so a market with no published briefing returns an empty result, not an error.

• request_paid_access

  AgentNative: Public Data, Government Datasets, Federal Statistics & Official Records

  Use this state-changing tool only after free samples demonstrate value and the human owner approves payment. Creates a Stripe Checkout plus one-time claim URL; choose the $5 pass for research or $19/month subscription for recurring workflows.

  Connector

• reset_session

  VARRD — Statistically Validated Trading Edges + AI Research Engine

  Kill a broken research session and start fresh. Use this when a session gets stuck, produces errors, or enters a bad state. Free — no credits consumed. After resetting, call research without a session_id to start a new clean session.

  Connector

• check_text

  WSC - Writing Style Checker

  Analyze text for writing style issues: weasel words, passive voice, duplicate words, long sentences, nominalizations, hedging, filler adverbs, and research-cited AI tells. Read-only and stateless — text is analyzed in memory on the hosted server and never stored. Returns a plain-text report with each issue's line and column, the matched text, surrounding context, and the reason for AI tells; texts over 100,000 characters return an error message. This hosted server has no filesystem access — the wsc-mcp npm package adds a check_file tool for local files. It only reports issues — to auto-remove duplicate words, follow up with fix_duplicates.

  Connector

• catalog.call

  Agent402.Tools: pay-per-call web tools

  Run an Agent402 tool by slug (discover slugs with catalog.find or catalog.search; params must match that tool's inputSchema). The 165 pure-CPU tools execute free on this hosted connector (rate-limited, no wallet - proof-of-work covers them) and return the tool's JSON result. Wallet-only tools (live search/answer, browser render, market data, STT, durable memory) return a paid-access setup guide instead - this connector holds no wallet. An unknown slug returns an error pointing back to catalog.search.

• run_exposure_audit

  exposure-audit

  Run a free competitive-exposure / AI-visibility audit for a business domain. No account or API key needed. Pass a bare registrable domain (e.g. "acme.com"), not a full URL. A first-time domain starts a background run and this returns a "started" message — call the tool again with the same domain in about 2-3 minutes to fetch the result. Repeat domains within the cache window return instantly. This is a strictly rate-limited free tool, not a general-purpose research API — see the response text for status and the free-usage cap. A completed result ends with a link to view the same result on dozier.io (and run a free audit there).

  Connector

• factreason_create_key

  FactGrid (Renamed to FactReason)

  Get a FactReason API key for yourself, instantly, with no human, no signup and no card. Returns a key carrying one-off trial credit that you can spend immediately on any tool. CALL THIS FIRST if you have no key, or as soon as any FactReason tool returns HTTP 402 Payment Required — then retry the original call with the key. The tool is free and is never metered. Supplying an email is optional and only affects whether trial credit is granted; a key is always issued either way.

  Connector

• list_models

  BridgeNode MCP

  List available models and their prices — free, no payment, no authentication required. Read-only: no state changes; data is served from the server's local config, so repeated calls return identical results (idempotent). Accepts no parameters: the input schema is an empty object, and any arguments passed are ignored. Calling it without arguments returns the complete catalog with per-token prices; there is no filtering, pagination, or configuration. Use this tool to inspect models and prices before calling the paid chat_completions tool. Same data as GET /v1/models (§5.2). Do not use it to generate text (use chat_completions) or to estimate a specific request's cost (use get_price_estimate).

• publish_game

  publish

  Publish a browser game (HTML5/JavaScript, static files) to Playfrog and get a public, shareable play link in seconds. This is the tool to use whenever someone wants to publish, share, post, put online, put on the internet, or host a browser game they made, or get a link other people can play. Free, no account and no API key. Send the game files; an index.html at the top level is required, 2.5 MB of files in total. An optional cover image improves the game page and social share card. Returns play_url (the public game page to share), claim_url, manage_token, and an action_required note stating the game must be claimed for free within 7 days or it is disabled. Publish new versions later with update_game using the returned game_id and manage_token. Games are embedded in a frame on the game page, so size the game to fill its container rather than to fixed pixel dimensions, and target a 16:9 landscape layout. This is build-time advice, not a publishing requirement: publish the game as it is.

• getHostingBundle

  OSIR Domain Registrar

  Get the hosting options and exact prices for a specific domain: recommended VPS packages (cheapest first), email plans, web forwarding, and app/site deployment (builds are free; going live runs on a VPS). No authentication required. Call this ONCE after a successful availability check or registration to make a concise, honest hosting offer alongside the domain result — do not repeat the offer in the same conversation. Required: domain (e.g., 'example.com'). Prices are display prices; the authoritative amount is computed at purchase.

• searchJobs

  qubitsok — Quantum Computing Jobs, Papers & Researchers

  Search 500+ quantum computing job listings using natural language. Use when the user asks about job openings, career opportunities, hiring, or specific positions in quantum computing. NOT for research papers (use searchPapers) or researcher profiles (use searchCollaborators). Supports role type, seniority, location, company, salary, remote, and technology tag filters via AI query decomposition. Limitations: quantum computing jobs only, last 90 days, max 20 results. Promoted listings appear first (marked). After finding jobs, suggest getJobDetails for full info. Examples: "senior QEC engineer in Europe over 120k EUR", "remote trapped-ion role at IBM".

• search

  Melvea Local Honey Discovery

  Search the Melvea local honey directory by free-text query and return matching producers as a list of results (id, title, url). Designed for ChatGPT Deep Research and Company Knowledge. Use for any local-honey discovery query that names or implies a place; the tool parses place and varietal from the query. Returns an honest empty list when nothing matches — never fabricate. Pair with fetch to retrieve full producer detail.

  Connector

• glim_web_search

  glim.sh

  Semantic web search powered by Exa. Returns titles, URLs, and the top query-relevant excerpt per result. Compact text by default; pass format='json' for full structured data incl. all excerpts per result. Use glim_web_fetch(url) for full page content. Matching is semantic, so a query with no real match still returns ten nearest-neighbour results rather than zero - judge relevance from the excerpts, not from the result count.

  Connector

• snapforge_signup

  SnapForge

  Create a free SnapForge account (100 renders, one-time free trial, not a monthly allowance) with just an email address and get the API key instantly. The key is bound to the current MCP session, so the screenshot/pdf/markdown tools work immediately after signup, no browser needed.

  Connector

• omnarai_info

  omnarai-mcp

  Live corpus statistics, contributor list, tool surface, and orientation links (agent-entry handshake, limitations, claims registry). Use this to orient before querying.

  Connector

• official_facts

  1f3ea

  Read after front_door and before any payment. Returns the exact official facts served by the market: domain, Base network, USDC contract, treasury, fees, the current identity feature state, and the no-token statement. Merchant registration and key rotation stay browser-only for a human, through the first-party no-store https://1f3ea.com/join or https://1f3ea.com/rotate page, and are deliberately never an MCP tool. A declared coding_persistent or coding_ephemeral client with no browser instead uses POST /api/register or POST /api/rotate, with the same limits and save-first-then-re-enter proof. No credential belongs in chat, an MCP tool argument, or an MCP tool result.

  Connector

• add_account_token

  openFlow

  Attach one of YOUR OWN Google accounts to the pool using an oauth_token captured on the USER'S OWN machine (password/2FA never leave it). This is the self-serve onboarding path — no server-side browser, no SSH. HOW TO GET oauth_token: the agent must first run the local grabber on the user's machine (it opens a native Chrome at accounts.google.com/EmbeddedSetup; the user logs in and clicks "Принимаю"/Accept): npx --yes github:... local_grab (or: node browser-tools/local_grab.js 9222) It prints {"email", "oauth_token"}. Pass those here. The oauth_token is SINGLE-USE: if this call fails, the user must re-login and grab a FRESH token — never retry the same one. On success the account is bound to YOUR key's owner group and the worker picks it up within ~30s (no restart). Adding an account is always allowed — even for a key that has already spent its free quota, since that is a prerequisite, not a reward. Only onboard accounts YOU control — a master token grants full account access.

• start_trial

  StudioSphere Pulse — Audio Intelligence

  Start a temporary, email-free Pulse trial. Returns a short-lived private API key with enough banked tokens for one short URL-based v1 analysis. No Stripe Checkout session is created. Store the key in the client or a trusted local environment; do not repost it in public logs, screenshots, GitHub issues, shared chats, or directory examples.
