Endpoint Security46
Transport & Reachability100
Schema Quality & AI Usability68
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 5900 tokens (~56/item across 104 items; 104 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage86
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 59% of tool parameters carry a description.Partial
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 104 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 104 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the io.github.huwhitememes/tollbooth MCP server?

io.github.huwhitememes/tollbooth is a hosted endpoint at https://agenttoll.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the io.github.huwhitememes/tollbooth MCP server?

io.github.huwhitememes/tollbooth is an MCP server listed in the public MCP registry as io.github.huwhitememes/tollbooth. 37 paid x402 MCP tools for OSINT, prediction markets, web intel, and agent security on Base USDC. This page covers its hosted endpoint (https://agenttoll.dev/mcp).

Is the io.github.huwhitememes/tollbooth MCP server safe to use?

io.github.huwhitememes/tollbooth scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.huwhitememes/tollbooth MCP server expose?

io.github.huwhitememes/tollbooth exposes 104 tools: ping, scrape, detect_stack, extract_contacts, score_lead, and 99 more. Their descriptions and schemas cost roughly 5,900 tokens of context every time the server is loaded.

Does the io.github.huwhitememes/tollbooth MCP server require authentication?

No. We connected to io.github.huwhitememes/tollbooth without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the io.github.huwhitememes/tollbooth MCP server still maintained?

io.github.huwhitememes/tollbooth is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
