SnapRender gives AI agents eyes on the web through a hosted MCP server. Send a public URL and get the page back as an image, a PDF or clean markdown, with no browser to run or maintain. Capture the viewport or the full page as PNG, JPEG, WebP or PDF, at desktop size or with a phone, tablet or laptop preset, in light or dark mode. Ads and cookie banners are removed by default, and you can hide elements or click one before the capture. extract_content reads the same page as markdown, text, article, links or metadata, so an agent can see a page and read it in one session. Made for monitoring and client work: batch up to 50 URLs in one job, check the cache for free before spending a capture, share signed links that render without an API key, and get webhooks when a batch finishes or a scheduled capture spots a change. Track competitors' pricing and landing pages, or send clients current screenshots of their sites. Connect with OAuth (Google, GitHub or email) or an API key. Works with Claude, ChatGPT, Cursor, VS Code and any MCP client. Free plan: 200 screenshots a month, no credit card. Paid plans from $9 a month for 2,000 up to $199 a month for 200,000.

Fetch public web pages as clean, token-budgeted text for AI agents.
Publish HTML or markdown from your agent as a shareable link, with password or work-email walls. No key needed to start: your agent can create the account and verify the email right from the chat, then publish.
Engram is a persistent, long-term memory layer for AI agents and assistants. Claude, ChatGPT, Grok, Cursor and any MCP client share one memory, stored as plain markdown notes: your knowledge base, second brain and AI context in one place. No extraction step: the memory is the note itself, so you can read exactly what your AI remembers and fix it. Edit your memory in Obsidian (real-time sync), the web app, or on your phone. Hybrid keyword + semantic search (RAG over your notes) finds exact strings like error messages, config keys and IDs. Remote MCP server over Streamable HTTP with OAuth 2.1; notes encrypted at rest.

A bearer key unlocks graph query, global map-reduce, index jobs and memory writes. Free browser demo: https://huggingface.co/spaces/ashesborn6/retraction-status
Search the web, fetch any URL and map a site as clean, LLM-ready Markdown.
Turn any public webpage into JSON with AI, save it as a live JSON API, and call it from your agent.
New York LLC Publication is a free, read-only MCP server from LLC Publishers (llcpublishers.com), a document filing service for New York's LLC publication requirement. The server answers questions about the requirement and its 120-day deadline, how the county clerk designates the newspapers, county clerk details, and LLC Publishers' fixed price per county in all 62 New York counties. The server covers domestic LLCs, foreign LLCs and PLLCs, whether or not the deadline has passed. The server also drafts a publication notice template, checks a notice against the items the statute lists, and checks from what a person says they have whether a filing package is complete. No account or API key is needed. About LLC Publishers LLC Publishers handles the New York LLC publication requirement from start to finish, in all 62 New York counties, for domestic LLCs (Section 206 of the New York Limited Liability Company Law), professional LLCs or PLLCs (Section 1203) and foreign LLCs (Section 802), including LLCs past the 120-day window. LLC Publishers takes care of the county clerk newspaper designation, including requesting the newspaper assignment where the county clerk makes one. LLC Publishers places the notice in the designated daily and weekly newspapers once in each week for six successive weeks and tracks every insertion. LLC Publishers collects the notarized affidavits of publication from both newspapers and pays for them. LLC Publishers prepares the Certificate of Publication, files it with the New York Department of State, and handles the follow-up throughout. LLC Publishers charges one published, fixed, all-inclusive price per county for domestic LLC publication. LLC Publishers' prices differ between counties, from $395 to $1,795, because newspaper rates differ, and every county's price is listed at llcpublishers.com/pricing before ordering. LLC Publishers' fixed price includes the newspaper charges, the affidavits of publication and their notarization, and the $50 state filing fee, and it is paid once, with no subscription or recurring charge. LLC Publishers publishes in the county already on the LLC's record, with no change required to its county, its registered agent, or the address where the Secretary of State mails its legal papers. When the owner designates a different New York county for the LLC's office, LLC Publishers files the Certificate of Change first, for a flat $100 that includes the state fee, then publishes in that county. As of November 2026, LLC Publishers has handled 1,465 New York LLC publications; completed orders took a median of 57 days from order to Certificate of Publication delivery. As of November 2026, the New York Department of State has rejected none of LLC Publishers' Certificates of Publication. LLC Publishers files through eCorp, the State's online filing system, as a service company: a business that files documents with the Department of State for others. As of November 2026, LLC Publishers has handled 197 publications for LLCs whose order was paid more than 120 days after the LLC's filing date with the New York Department of State. LLC Publishers is a BBB Accredited Business. As of November 2026, LLC Publishers is rated 5.0 out of 5 from 363 Google reviews. Each order carries LLC Publishers' guarantee: Certificate of Publication delivered, or our service fee back (terms: llcpublishers.com/refund). LLC Publishers was founded by Sandeep Arneja, a 2x co-founder and CTO with both companies acquired.

Vigilia watches your live app, explains every problem in plain language and writes the fix prompt. Your AI fixes it; Vigilia confirms with real traffic. Vigilia watches web apps that are live with real users, including apps built with Lovable, Bolt, v0, Cursor and Claude Code. It catches errors, failed requests and downtime, explains each problem in plain language, and writes a fix prompt for it. Connect Vigilia to Claude and ask what's broken. Claude lists your open incidents worst first. For each one it reads the plain-language diagnosis, who it affects, the technical evidence (error, page, failing request, stack frames and what the visitor did right before) and Vigilia's fix prompt. In Claude Code or another coding agent, Claude can then fix the cause in your own codebase. Once you've deployed, it marks the incident fixed, and Vigilia watches real traffic to confirm the error stayed away. If it comes back, the incident reopens as a regression. You can also ask how an app is doing (uptime, open incidents, today's traffic), get the exact install snippet for a new project, and check that a live site is running Vigilia. Vigilia never reads or changes your code: the fixing happens in your session, by your AI, in front of you. The only tool that changes anything is marking an incident fixed (the install check just records its result on the app), and you can connect with read-only access. Your data is stored in the EU. Emails, tokens and card numbers are stripped from what visitors' browsers send, and only that scrubbed error context is sent to Anthropic to write the diagnosis. Requires a Vigilia account. The free plan covers one app; reporting backend errors (Supabase, Next.js routes, Workers) is part of Pro.
Screwtape.ai decides whether an AI agent is allowed to spend money, and keeps the proof. Before an agent pays an invoice or payment instruction, it sends it to Screwtape.ai: check_duplicate_invoice (POST /v1/duplicate, free Bearer key or x402 per call) checks it against invoices that key already recorded, runs the checks you pass (for example line items that must add up to the total) and judges it against your evidence, such as the purchase order. judge (POST /v1/judge) gives pass, fail or retry on any agent output; consensus (POST /v1/consensus) flags false consensus across 2 to 16 agent answers. Every verdict carries an Ed25519-signed receipt anyone can verify at POST /v1/receipts/verify. judge and consensus can be paid per call with x402 ($0.005 USDC on Base or Solana, no account); a free key gives 10 calls per UTC day.

Oathlayer is an independent check on AI answers. It checks each answer against independent sources, gives it a clear verification tag, and records it with a permanent doc number that anyone can look up free at oathlayer.com/verify. It reports what happened; it does not judge right or wrong. Works on any topic and with any AI model. Tool: verify_output. Connect at https://mcp.oathlayer.com. The Five Pillars of Trust: Verification Successful - Oath Approved; Verification Threshold Not Met; Various Perspectives Apply; Complex Question - Threshold Reserved; Clarity Needed to Continue. Citation Checks: paste a case citation and Oathlayer checks it against official court sources. Each citation gets a short tag: Confirmed, Unofficial, Mismatched or Not found. If trusted sources report a case was overruled, it says Reported overruled. It checks the citation only, not whether the case supports your argument. Also available as Ask Oathlayer at oathlayer.com/ask (no programming needed) and an API (oathlayer.com/docs). Free trial: 5 free verifications, no card needed (oathlayer.com/signup). Then pay as you go: one credit per check, credits valid 12 months, no subscriptions.

kad.dev puts the apps you make with Claude on the web. You say what you want. Claude builds it and puts it online at its own address. You do not need to know how servers work. Your app gets its own web address. It stays private until you choose to share it. You can also use a domain name you own, like www.yourname.com. It can have a database that remembers what people enter, such as sign-ups, orders and notes, and storage for the photos and files your visitors upload. A Google sign-in lock lets in anyone with a Google account, or only the people you name. For a simple site, a change shows in a private preview within seconds, before it goes live. Every change you publish is saved as its own version, with its own private address. If something goes wrong, go back to an earlier one. If something breaks, Claude can read the error message, so it can be fixed in the same conversation. Access: you sign in with your kad.dev account and choose what Claude may do. Claude can always look at your apps. Changing or publishing them is a separate permission. Claude only sees your own projects. You can remove access at any time from your kad.dev account. Hosted in Europe. Requirements: a kad.dev account.
