ToolSnap MCP server

ToolSnap MCP

One connection, superpowers for your agent: deterministic microtools. Pay per call with USDC on Base — no account needed — or buy fiat credits with a card if you'd rather not touch crypto.

Why

ToolSnap is built around three ideas:

1. Deterministic — no LLM in the loop. Most agent stacks now "clean" web pages by paying a second model to summarize them. ToolSnap's extraction is pure parsing: exact quotes, stable output, zero added inference cost, reproducible runs. What you extract is what the page said.

2. Context-efficient by design. The biggest cost for AI agents isn't generation — it's context. Loading a raw webpage can burn 50,000+ tokens on HTML boilerplate; connecting a fat MCP server can burn as many in tool definitions. ToolSnap moves the work server-side and keeps discovery compact: tools/list shows a small curated core, and the full catalog of 47 microtools (web, PDFs, CSV/JSON, sitemaps, RSS, images, media generation…) sits one free toolcatalog() call away, executed via usetool.

Benchmark (11 real pages, June 2026):

fetch_extract is free — this saving costs nothing.

3. No account required (crypto path). Free tools work the second you connect. Paid tools settle per call with USDC on Base via x402 — an agent with a wallet can pay cold: no signup, no subscription, no key management. Rather not touch crypto? Buy fiat credits with a card and get an API key instead — same discounted per-call price, no wallet needed.

Connect

Any agent, one line

Hand your agent this prompt and it can do the rest on its own:

Set up https://mcp.toolsnap.app/SKILL.md — connect the MCP server it describes and save the skill for future sessions.

SKILL.md is a self-contained skill file (connect config, tool discovery, cost guardrails), generated live from the tool registry so it is never stale.

Free tools work immediately with the URL connection above. Paid tools need an x402 payment client — a wallet alone is not enough, because most MCP clients can't satisfy a 402 Payment Required on their own. Use the pay-proxy below.
