Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “list_endpoints”: Free. List every endpoint (core products first) with its price in USDC, description and example query. Core: invoice-json $0.0075/page, toke.”
“Use “mcp_servers_sample”: Free. Five sample MCP servers from the 4,259-server directory (MIT source).”
“Use “llm_pricing_sample”: Free. List prices of five popular LLMs (USD per 1M tokens, LiteLLM table, MIT).”
“Use “api_directory_sample”: Free. Five live public APIs that need no key.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how FreeTier Agent API holds up.
Operated by FreeTier Agent API (pages.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If FreeTier Agent API adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose FreeTier Agent API in the gate directory. No sign-in needed.
FreeTier Agent API's tools are live in every AI client you've connected — with rules and logging built in.

https://freetier-agent-api.pages.dev/mcpYes — FreeTier Agent API operates its own remote MCP server at freetier-agent-api.pages.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick FreeTier Agent API in the directory. No account or sign-in is needed. From then on, FreeTier Agent API's tools are available in every client you've connected to gate.
No. FreeTier Agent API runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Yes — you can get started with gate for free and connect FreeTier Agent API in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
