Overview

AI-generated overview

Remote MCP server offering 37 paid x402 tools for web scraping, OSINT, prediction-market signals, and agent security checks, billed in Base USDC.

What you can do
  • Fetch and analyze web pages: scrape structured content, fingerprint tech stacks, extract contacts, check robots.txt and agent policies
  • Research companies and leads: enrich domains, score outbound fit, validate agent manifests, find agent-useful resources
  • Assess agent safety: static risk briefs for MCP servers and tool manifests, approval and spend-policy packs, OWASP Agentic threat lookups, malicious MCP package IOCs, trifecta scoring, policy templates
  • Scan prediction markets: Polymarket and Kalshi arbitrage and resolution scans, scenario verdicts, weather bias, attention momentum, SEC filing velocity, FRED and Treasury signals
  • Gather OSINT and macro data: geopolitical and flight intel…
When to use it
Useful when an assistant needs on-demand web intelligence, lead enrichment, prediction-market or macro signal research, or a pre-connection safety review of another MCP server or tool manifest, without running local infrastructure.
Requirements
A remote streamable HTTP endpoint at agenttoll.dev; no local package, environment variables, or headers are declared. Tools are described as paid x402 tools settled in Base USDC, so a compatible paying client or wallet is implied.
Before you install
Tools are paid per call in Base USDC, so usage can spend real money; confirm pricing and set spend limits before enabling. Several tools send target URLs and domains to third-party sources, and outputs are described as intelligence only, not verified trading or legal advice. No authentication is declared, so review what data you submit.

Installation

In SourceWeft

  1. Open Tollbooth in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.huwhitememes%2Ftollbooth/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
