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.

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.

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.

Rivul is a free, read-only remote MCP server for searching scholarly literature. It runs semantic search over more than 300 million paper records from a dated OpenAlex snapshot, so an agent can find papers by meaning rather than exact keywords, then open the full record for any result. Tools: - search_papers: semantic search with optional filters for publication year range, minimum citation count, open access only, topic and field. Sort by relevance, most cited, newest or oldest. - get_paper_details: the full record for one work by its OpenAlex ID: title, every author, venue, work type, topic, field, publication date, citation count, DOI and open-access links. - usage_status: the workspace's MCP usage for the current day. Results come only from the index, never from a model. Each result carries a stable OpenAlex ID so the source can be checked, and every response states the snapshot date. Useful for literature reviews, scoping reviews, finding highly cited or open-access papers on a topic, citation chasing, and checking that a cited paper exists. Free for every account, with no plans or payment. Sign in with Google through OAuth 2.1 (PKCE, dynamic client registration), or use an MCP key from rivul.ai. Endpoint: https://rivul.ai/mcp (Streamable HTTP). Setup and docs: https://rivul.ai/features/atlas

Bewary is a scam detection API and MCP server for apps and AI agents: phishing, fraud and threat intelligence lookups an agent runs before it opens a link, calls a number, pays or replies. It checks links and domains (phishing, domain age, lookalike brands), IP addresses, phone numbers (FTC and FCC complaints), SMS short codes, email addresses, crypto wallets (scam reports, OFAC sanctions), IBANs, mobile apps and payment handles. Each answer is a typed verdict (scam, suspicious, safe or unknown) with the facts and reason codes behind it, built from evidence rather than a language model. Watches send an event when a watched domain, number, wallet or brand changes. A free key gets 1,000 credits a month with no card; OAuth sign-in is supported.
