Documentation Overview

ToolHail

The discovery-and-payment layer for AI agents. ToolHail lets an AI agent find the right MCP (Model Context Protocol) server for any task and call it — paying per use — without installing anything.

There are 10,000+ MCP servers an agent could use, and no good way to discover and use one mid-task. ToolHail closes that gap with two tools:

🔎 find_mcp_server (free) — describe a capability in plain language ("query a Postgres database", "send a Slack message", "scrape a web page") and get ranked, deduplicated MCP servers from every major registry (mcp.so, PulseMCP, Smithery, Glama) with ready-to-paste setup.
⚡ call_tool (paid) — invoke a discovered remote MCP server through ToolHail's SSRF-guarded proxy. No install, one hop; each successful call is metered and billed through Stripe.

Use it

Hosted MCP endpoint (Streamable HTTP):

Code

https://mcp.toolhail.com/mcp

Add it to Claude Code (or any MCP client):

Terminal

claude mcp add --transport http toolhail https://mcp.toolhail.com/mcp

MCP Scout on the Apify Store — the discovery engine as a standalone, pay-per-search actor: https://apify.com/01010101/mcp-scout

Site: https://toolhail.com · Guide: https://toolhail.com/guide

How it works

Discover — the agent hits a capability gap and asks find_mcp_server, which searches the registries and returns the best-fit servers, ranked for usability.
Execute — instead of installing, the agent calls the chosen tool via call_tool; ToolHail proxies it in one hop, nothing to configure.
Settle — each successful call is metered and billed through Stripe. The agent pays for exactly what it used.

Why it exists

An agent's toolset is fixed at configuration time, but real tasks need capabilities the agent doesn't have. Today the options are "hard-code every server you might ever need" or "give up." ToolHail makes tools a runtime resource: discovered on demand, called through one endpoint, paid per use. It is discovery and payment infrastructure for the agentic web — built entirely on the open Model Context Protocol.
