AgentKey

AgentKey

Freemium

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

Key features

  • 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.

Best for

  • 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.

Arcade

Arcade (ArcadeAI)

Freemium

A tool-calling platform that lets AI securely act on users' behalf via authenticated integrations and developer SDKs.

Key features

  • Authenticated Integrations: Provides secure, managed authentication flows so agent tools can act on behalf of users without exposing credentials, triggered via user_id in agent context.
  • Tool Development Kit: A toolkit and CLI for building, testing, evaluating, and deploying agent tools with standardized interfaces and local development workflows.
  • Multi-language SDKs: Official Arcade clients for Python (ArcadePy), TypeScript (ArcadeJs), and Go (ArcadeGo) to integrate Arcade tooling into diverse applications and backends.
  • MCP Server Framework: An Arcade MCP framework and server templates to create, deploy, and share MCP servers that serve tools to agents and integrate with the Arcade platform.
  • Hosted Agent Examples: Prebuilt reference agents (chat.arcade.dev, Slack Agent, Social Media Agents, Agent TODO) demonstrating integrations and real-world agent behaviors for rapid onboarding.
  • Tool Testing & Evaluation CLI: Command-line tooling to locally run, simulate, and evaluate tools and agent interactions before production deployment.
  • Authenticated integrations (tools) allowing AI to act on behalf of users
  • Tool Development Kit (library + CLI) for building, testing, evaluating, and deploying tools
  • Official client SDKs: ArcadePy (Python), ArcadeJs (TypeScript), ArcadeGo (Go)
  • REST API and API documentation (docs.arcade.dev)
  • MCP Server Framework for creating and deploying Arcade-compatible servers
  • Example agents and reference apps (chat.arcade.dev, Slack agent, social media agents)
  • Integrations and examples using Vercel AI SDK and Next.js for chat frontends
  • Managed tool authentication flows (triggered via user_id in agent context)
  • CI/deployment-friendly repos and example deployment instructions for Next.js
  • Open-source repositories and community support (GitHub, Discord)

Best for

  • Autonomous Task Execution: Build agents that can read email, schedule meetings, and update calendars securely by calling authenticated integrations on users' behalf.
  • Team Collaboration Integrations: Deploy a Slack Agent that uses Arcade tools to take actions (create tickets, post updates, run queries) directly from Slack conversations.
  • Social Media Automation: Create agents that curate, schedule, and publish social media posts across platforms using authenticated social media tool integrations.
  • Developer Tooling & Rapid Prototyping: Use the Tool Development Kit and SDKs to rapidly build, test, and iterate new agent tools and CLI workflows locally before deploying.
  • Application Embedding: Integrate Arcade with web or mobile apps via SDKs to enable in-app agents that perform backend operations through secure tool calls.
  • MCP Server Deployment: Package and deploy MCP servers with Arcade's framework to share custom tool collections across teams or public tooling ecosystems.
  • Build conversational agents that call external services and perform actions on behalf of users
  • Create chatbots with authenticated integrations (Google, social platforms, Slack)
  • Autonomously curate and post to social media using tool integrations
  • Develop and deploy MCP servers and agent backends
  • Embed intelligent chat frontends (Next.js + Vercel AI SDK) that use Arcade tools
  • Prototype and test agent tools locally with the Tool Development Kit and CLI
  • Integrate Arcade tools with OpenAI Agents SDK via adapter libraries
