"Toll" matching MCP servers:

Robinhood Chain safety checks for trading agents: check a coin before buying (who is behind it, bundles, dev record, LP), check a transaction or x402 payment before signing (ALLOW / WARN / BLOCK), ERC-8004 agents, Uniswap v4 hooks and Stock Token data. Read-only, free tier, no key.

Measured trading-venue tolls (fee, spread, slippage) with per-venue freshness and evidence. list_venues is free; get_toll costs $0.05 USDC on Base via x402.

Lets AI agents and developers list a catalog of troubleshooting datasets, preview up to three records per product for free, and get Lightning payment instructions to unlock full structured datasets.

Exposes nine purpose-built tools for EVE: Frontier on Sui Move, covering Smart Assembly contract coding, Smart Gate route and toll planning, Network Node gigajoule optimization, Smart Turret targeting, killmail threat intel, SSU market making, zkLogin character verification, sovereignty fuel tracking, and PTB drain simulation.

Enables scoring the WHO-5 Well-Being Index from five answers, returning a 0–100 score and a low, reduced, or normal band without providing a diagnosis.

MCP router that fronts your other MCP servers behind a few small generic tools, so their tool definitions stay out of the context window and are discovered on demand.

Audits MCP tool descriptions for quality and reliability, scoring them 0-100, detecting smells, and providing rewritten versions for better agent accuracy.

Graph-based tool retrieval for LLM agents. Builds a tool graph from OpenAPI/MCP specs and retrieves multi-step workflows via hybrid search (BM25 + graph traversal + embedding), recovering accuracy from 12% to 82% with 79% fewer tokens. Also works as an MCP Proxy to aggregate multiple servers behind 3 meta-tools.

Enables any existing API to become a pay-per-call service for agents by issuing HTTP 402 payment requests and settling USDC payments via CDP, while exposing MCP tools that charge per call and support Bazaar discovery.

Self-hosted daemon connecting Claude Code, Codex, and other coding agents across machines via MCP + A2A: delegate tasks, ask questions, share results, and wake sessions.

Fully autonomous, crypto-monetized MCP server on the Base network. Provides premium smart contract auditing, patching, and token data arbitrage using the x402 micro-transaction protocol.

An unofficial local Python MCP server that helps AI assistants write scripts for Roblox BedWars Creative. Search official scripting docs, create and edit Lua files, check them against cached APIs, and upload scripts with Easy.gg Code Sync. Live game testing remains manual.

Enables interacting with Planhat customer data via natural language, supporting CRUD operations on companies, contacts, opportunities, notes, conversations, users, assets, issues, tickets, tasks, licenses, and invoices.

MCP server for the Trollspace API that exposes 47 type-safe tools for managing snippets, nuggets, todos, ideas, tools, repos, travel, subscriptions, and more.

Enables agents to synthesize typed MCP tool schemas at runtime, validate Python ASTs for unsafe imports, compile sandboxed callable handlers, and hot-plug them into an active MCP runtime. It provides a zero-dependency, standard-library-only MCP server for safe just-in-time tool creation and execution.

Enables agents and operators to audit MCP tool permissions for least privilege, score blast radius, detect privilege-escalation chains, verify capability matrices, and produce cryptographic audit proofs with injection fuzzing and exfiltration canaries.

Enables AI agents to look up US NHTSA and EU Safety Gate car recalls and complaints, compare a model's years by risk score, check UK MOT failure rates, retrieve EU vehicle specifications with WLTP CO2 and fuel consumption, and verify Cyprus company records, EU VAT numbers via VIES and LEIs. It draws only on official open data and is hosted through Apify, so nothing needs to be installed.

20-tool MCP server - production web-intelligence API gateway exposing 10 Website Intelligence + 7 Marketing APIs as 20 MCP tools over Streamable HTTP + stdio, with pay-per-call Solana USDC payments. 20 tools: URL-to-Markdown, metadata, technology detection, contact extraction, SEO audit, SSL, DNS, sitemaps, robots.txt, Google Maps reviews, AI company/website summaries, citation checking Cloud-host

Enables autonomous agents to automatically repair and guard tool-call schemas through deterministic AST analysis and parameter projection validation, ensuring reliable, schema-compliant interactions in MCP-compatible environments.

Enables agents and MCP-compliant clients to resolve tool execution graphs by scheduling calls as a topological dependency DAG, running independent tools in parallel batches while speculatively prefetching and evaluating arguments. This cuts latency and token burn by handling routine tool orchestration deterministically without extra LLM round-trips.

Protects AI agents from bad tool outputs, schema mismatches, and tool poisoning by validating, sanitizing, and scoring reliability of tool responses.

MCP server that detects and guards against tool poisoning and prompt injection attacks in tool descriptions and schemas. It provides risk scoring, pattern detection, safe rewriting, and audit reports with zero external API cost.

Enables agents to search a catalog of 216 browser-based file tools and hand users a working link instead of generic advice, while also running small stateless helpers for text stats, hashing, UUIDs, passwords, JSON, Base64, colour conversion and QR codes.

Lets a human review what an AI agent is about to post to a chat tool (Slack first) before it is sent. Renders the draft, destination and warnings (@here/@channel, unresolved mentions, format issues) in a neutral local HTML preview; never sends anything.

Analyzes multi-step AI agent tool chains to compute success probability, identify bottlenecks, and suggest better execution orders, enabling more reliable agents via local pure-math computation.

Automated risk triage, liquidity checks, and security guardrails for AI agents operating on the AO / Arweave network.

Pay-per-call tools for AI agents via x402 (USDC on Base): web-to-Markdown, PDF, provenance (human vs synthetic), trusted lookup with citations, a 3.9M-business global directory, LatAm ID validators, agent-forged tools and 2,000+ proxied x402 services. No API keys, charged only on success, free trial without a wallet. Remote: https://toll402.dev/mcp · Local: npx -y toll402-mcp

This MCP server wraps agent tool calls with fault-tolerant retry logic, including adaptive exponential backoff, full jitter, 429 rate-limit backpressure handling, and circuit breaker patterns. It enables autonomous agents to execute tools reliably without frontier LLM round-trips, using a zero-dependency Python stdio JSON-RPC interface.

Enables AI agents to track, calibrate, secure, and audit Milwaukee M18 FUEL ONE-KEY power tools through BLE proximity, geofencing, torque profiles, remote lockout, and fleet telematics.

A tiny always-loaded gateway that lets any MCP-capable client discover all context assets on demand via progressive search, avoiding token cost.
