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.

Pay-per-use APIs for agents: web research, data lookups, and metered endpoints billed to credits.
Shared project memory for AI coding agents: decisions, lessons, risks and tasks in one graph.
Read-only access to your own crypto portfolio across 11+ exchanges and 20+ chains: holdings, full history, FIFO cost basis and P&L, fees and income. Ask Claude or ChatGPT about your portfolio; the connector can never trade, move funds or act as a login.
Files what you learn into a personal wiki and quizzes you before you forget it.
Writes your daily standup from GitLab or GitHub merge request state: what's ready, blocked or waiting on your review, and why a pipeline is red, read from the failing job log. OAuth sign-in, no API keys; can post the note to Slack, Discord or Google Chat on a schedule.
Company and contact enrichment: firmographics from a domain or IP, profiles from a work email.
Build, validate and deploy workflows as Cloudflare Workers in your own account, with approval.
VPN, proxy, Tor, hosting and CDN detection for any IP address, from the VPNDetection API.
Generate synthetic random user data for testing, demos, and development without using real persona.
AI dispatch for food & local delivery: assigns orders to drivers, sequences stops, times departures.
Registered agents sell what they measured, anyone buys: validated knowledge and signed datasets. No sign-in needed to connect: searching, dataset listings and free reads work anonymously. Sign in (OAuth) only for selling and account tools.
Memory for AI agent teams across tools, sessions, repositories, and teammates.
Natural AI voiceovers: search 500+ voices, generate speech, design and save custom voices.
Hosted agent memory that learns from outcomes, with shared rooms. No key: mcp.mnemoverse.com/mcp
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.

Let your AI agent pay for APIs and data without handing it your money. In ChatGPT, Claude or Grok, the agent finds paid x402 APIs (with each seller's payout record from x402 Doctor) and asks to pay; you approve and sign each payment in your own wallet: MetaMask or Coinbase Wallet (USDC on Base), Phantom (USDC on Solana) or Xaman (RLUSD on the XRP Ledger). Fizzl checks every payment before you sign and every paid answer for hidden instructions. Fizzl never holds your keys. Free to start.
The only News based AI MCP your agents will ever need — custom categories, global regions, and time-scoped results in one tool. We use multi-vector & sparse-hybrid search to search through thousands of articles across the world to find the exact news you're looking for.
Coding agents in multi-service codebases routinely rebuild existing helpers, trust stale type definitions, and modify API contracts without knowing who consumes them. Carrick solves this by indexing your entire TypeScript ecosystem across service and repository boundaries. By integrating deeply with the TypeScript compiler, Carrick traces every route, type, and cross-service call while recording function behaviour so agents search by intent rather than name. Delivered via MCP for AI agents and LSP for IDEs, Carrick ensures models see existing endpoints and utilities before generating new code. The scanner is source-available and runs from your CLI or CI pipeline.
Runtime permission, approval, and audit layer for AI agent tool execution.
