AgentKey

Freemium

One MCP install that gives AI coding agents live search, social, finance, and on-chain data through a single subscription.

Unified MCP Install: One install command wires the key into Claude Code, Cursor, Windsurf, Codex, Gemini CLI, and OpenCode without per-vendor setup.
Multi-Provider Search Routing: Ships six search backends (Brave, Tavily, Serper, Perplexity, Parallel, Exa) with automatic failover when a source is thin or blocked.
Web Scraping Backends: Bundles Firecrawl, Jina Reader, and Bright Data so agents can turn any URL into clean markdown or structured content.
23 Social Media APIs: Reaches closed platforms like X, Reddit, LinkedIn, TikTok, Douyin, WeChat, Weibo, and Xiaohongshu that agents usually cannot browse.
On-Chain and Crypto Data: 14 crypto providers cover market caps, DEX pools, wallet balances, NFTs, RPC calls, and prediction markets in one call.
Shared Credit Balance: A single monthly credit pool spans every service, so there are no per-API quotas, overages, or duplicate invoices.
Fallback Path Switching: When a data source hiccups mid-session, AgentKey reroutes to an equivalent provider so the agent keeps working instead of failing.

Product Research: Have an agent scan Reddit and X for subscription-product complaints and turn them into a prioritized pain-point brief.
Growth Marketing: Aggregate social signals across TikTok, LinkedIn, and Xiaohongshu to spot early trends for a campaign.
Crypto Analysis: Ask an agent to pull on-chain wallet activity, DEX pool prices, and token sentiment in one prompt.
Competitive Intelligence: Compare marketplace positioning by scraping product pages, Product Hunt launches, and Crunchbase funding data.
Content Creation: Let an agent gather YouTube, Bilibili, and Threads discussion around a topic before drafting a script or post.
Financial Research: Pull macro time series from FRED, quotes from Yahoo Finance and Alpha Vantage, and filings from Finnhub inside a single agent session.

A hosted knowledge base every AI agent can read and write, shared across Claude, ChatGPT, Cursor and coding agents via connectors.

Connector Setup: Add OzBrain from the connector menu in Claude or ChatGPT, sign in and approve - no code, SDK or installation required.
Nested Article Retrieval: Knowledge is broken into nested pieces so an agent loads only the slice it needs, cutting tokens, latency and hallucination.
Automatic Supersession: When newer thinking arrives, OzBrain revisits existing articles, marks the old as replaced and links forward to the current version.
Staged Writes: Changes are proposed before they land, so multiple agents can write concurrently without clobbering one another.
Change Ledger: Every edit records the agent, the article and the stated reason, giving a readable history of how the brain reached its current state.
Shared Team Brains: Point a whole team's agents at one brain so context worked out in one person's chat is immediately available in everyone else's.
Broad Client Support: Works with Claude, ChatGPT, Claude Code, Cursor, OpenClaw, Hermes Agent, Gemini Spark where available, and any connector-capable client.
Markdown Export: Export everything as plain markdown at any time, including after cancellation, with deletion meaning the content is actually removed.

Cross-Agent Continuity: Stop re-explaining the same project context when moving between Claude, ChatGPT and a coding agent.
Single Source of Truth: Replace the scatter of launch-plan copies across Drive, Downloads, email and chat with one current version agents read from.
Team Onboarding: Give a new teammate's agents the accumulated decisions, research and roadmap the rest of the team already has.
Agent-Maintained Documentation: Let agents append findings and decisions as they work, with humans reviewing and correcting in the same place.
Rules and Skills Storage: Keep coding standards, conventions and reusable skills where Claude Code and Cursor pick them up automatically.
Long-Running Research: Accumulate customer research and competitive notes across many sessions instead of losing them to chat history.
