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.

Production-ready MCP server framework and firewall that protects MCP providers from prompt injections and PII leaks.

Key features

  • MCP Firewall: Network and prompt-level protection that detects and blocks prompt-injection attempts and prevents PII leakage from agent conversations, reducing data-exposure risk for users.
  • Python-Based Server Framework: Define tools, prompts, and resources as conventional Python files; Golf auto-discovers, parses, and compiles these components into a runnable MCP server to minimize boilerplate.
  • Built-in Auth & Access Control: Integrated authentication and authorization primitives to manage user and agent permissions for secure production deployments.
  • Observability & Telemetry: Runtime telemetry, logs, and metrics collection plus anonymous CLI usage telemetry to monitor MCP health, performance, and usage patterns for debugging and optimization.
  • Debugger & Runtime Tools: Developer-facing debugger and runtime facilities to run, inspect, and iterate on MCP behavior and tool integrations during development and testing.
  • Testing Framework (golf-testing): CLI tooling to test MCPs for performance, security, and compliance, enabling validation before production rollout.
  • Production Readiness: Features targeted at enterprise deployments such as scalable runtime components, telemetry hooks, and security-first defaults to run real-world MCPs powering AI agents.
  • MCP firewall layer to detect and block prompt injection attempts
  • PII leak detection and protection for user data
  • Production-ready MCP server framework implemented in Python
  • Built-in authentication and authorization components
  • Observability and telemetry integration for monitoring MCPs
  • Runtime tooling and debugger for developing and troubleshooting MCPs
  • Companion testing CLI/framework (golf-testing) for performance, security and compliance

Best for

  • Building production MCP servers that power multi-component AI agents with defined tools, prompts, and resource bindings authored in Python.
  • Protecting hosted MCP endpoints from prompt-injection attacks and preventing accidental leaks of PII or sensitive responses to users.
  • Running pre-deployment security, performance, and compliance tests using the golf-testing framework to validate MCPs at scale.
  • Integrating observability and telemetry into agent infrastructure to trace incidents, monitor usage, and optimize runtime performance.
  • Rapid prototyping and iteration of agent capabilities via the file-based component model and local debugger/runtime before production deployment.
  • Managing authentication and access control for enterprise MCP deployments to enforce permissioned use of tools and data by agents.
  • Protect enterprise MCP deployments from prompt-injection attacks and accidental PII exposure
  • Build and run production MCP servers that power AI agents with integrated Auth, Telemetry and Debugger
  • Run automated security, performance and compliance tests against MCP implementations using the golf-testing tool
  • Add observability and telemetry to MCP runtimes to monitor usage and troubleshoot agent behavior
