"Toll" matching MCP servers:

Paid remote MCP gate for caller identity, agent scope, task intent, data class, policy verdicts, and audit receipts.

Exposes an MCP server that routes every agent tool call through deterministic policy gates, budget escrow with clawback, authenticated approvals, and a hash-chained audit trail, enabling agents to safely perform money-related operations while receiving actionable denial reasons.

A server built on mcp-framework that enables integration with Claude Desktop through the Model Context Protocol.

An MCP server that implements the 'think' tool, providing Claude with a dedicated space for structured thinking during complex problem-solving tasks to improve reasoning capabilities.

Enables MCP apps to manage durable, model-defined goal phases with persistent state, checkpointed progress, and safe resumption after interruptions or lost turns, ensuring elapsed time never implies completed business work.

Enables AI agents to use paid MCP tools within a human-approved budget by holding a PayPal sandbox authorization, checking each call against policy, recording usage in a durable ledger, and capturing or voiding the authorization at session close.

Enables AI agents to propose changes, obtain human or policy approval, and safely apply them with drift checks, idempotency, verified completion, compensation, and a tamper-evident ledger.

Enables non-custodial guarding of autonomous Base USDC payments by checking an exact owner-mandated transaction immediately before a customer-owned AWS KMS signer can sign it.

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

Stateful backend for AI agents providing memory, watch, render, execute, and board primitives via remote MCP. Enables agents to persist facts, track page changes, render JS pages, run code, and coordinate on shared boards.

Provides a no-op 'think' tool that enables Claude to decompose complex problems and enhance reasoning by pausing to organize thoughts.

Implements Anthropic's 'think' tool for Claude, providing a dedicated space for structured reasoning during complex problem-solving tasks that improves performance in reasoning chains and policy adherence.

Official implementation of Anthropic's 'think' tool that provides Claude with a dedicated space for structured reasoning, improving performance by up to 54% on complex tasks requiring multi-step problem solving.

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.

An MCP server implementation of Anthropic's Think Tool prompt engineering technique that enables Claude to break down complex problems and enhance its reasoning capabilities by providing a simple tool that echoes back thoughts.

A Model Context Protocol server that provides Claude with a dedicated space for structured thinking during complex problem-solving tasks, helping improve its reasoning capabilities.

Enables coding agents to register tasks, report progress, save checkpoints, and report interruptions so an independent watchdog can automatically resume interrupted work from the same session or a saved checkpoint.

Facilitates interactive software development planning by managing tasks, tracking progress, and creating detailed implementation plans through the Model Context Protocol.

An MCP server that provides a "think" tool enabling structured reasoning for AI agents, allowing them to pause and record explicit thoughts during complex tasks or multi-step tool use.

A template for building tools based on the Model Control Protocol (MCP) framework, providing a structured way to develop and integrate custom tools with Cursor.

This is a powerful Model Context Protocol (MCP) server that integrates multiple AI coding agents—Anthropic Claude Code, OpenAI Codex, and Google Gemini—directly into your workflow. It enables seamless cross-provider analysis, leveraging Gemini's massive token window, Codex's specialized coding capabilities, and Claude's advanced reasoning.

MCP server that builds itself by creating new tools as needed based on user requests (Requires restart of Claude Desktop to use newly created tools).

An MCP tool enabling structured thinking and analysis across multiple AI platforms through branch management, semantic analysis, and cognitive enhancement.

A Model Context Protocol server that enables AI assistants to interact with Google Gemini CLI, allowing them to leverage Gemini's large token window for analyzing files and codebases using natural language commands.

Enables on-demand generation of TypeScript tools using an LLM with human-in-the-loop approval and safe sandboxed execution. It allows users to create and persist custom functionality through natural language requests.

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 coding agents to claim, work, and submit tasks on SerenEdge projects by exposing the platform's agent API as MCP tools.

Cyber Host Artificial Intelligence (C.H.A.I) An autonomous penetration testing MCP (Model Context Protocol) server with an integrated AI decision engine, multi-provider LLM support, and an extensible plugin architecture.

Enables AI assistants to interact with multiple AI models through the OpenCode CLI with a unified interface. Supports plan mode for structured analysis, flexible model selection, and natural language queries with file references.
