Each operation translates to Hetzner Cloud API calls with validation of CIDR ranges, port specifications, and protocol types. Returns network configuration state and rule application status.
Unique: Exposes Hetzner's network API through MCP's structured tool interface, allowing LLMs to design and implement network topologies conversationally without manual console navigation
vs alternatives: More accessible than AWS VPC configuration for simple use cases; less complex than Kubernetes network policies for single-region deployments
Provides MCP tools for registering SSH public keys with Hetzner Cloud and injecting them into servers during provisioning. Supports multiple key formats (OpenSSH, PEM) and enables servers to be created with specific keys pre-configured. Keys are stored in Hetzner's account and referenced by ID during server creation, eliminating the need for post-provisioning SSH key distribution.
Unique: Integrates SSH key lifecycle management into MCP's tool interface, enabling LLMs to handle authentication setup as part of infrastructure provisioning without requiring separate key management tools
vs alternatives: Simpler than managing SSH keys through Ansible or Terraform for one-off provisioning; more integrated than manual key distribution
Provides MCP tools for listing and inspecting Hetzner Cloud resources (servers, volumes, networks, SSH keys) with filtering and pagination support. Queries return structured JSON payloads containing full resource metadata, enabling LLMs to reason about current infrastructure state. Supports filtering by name, status, location, and other attributes to enable targeted queries.
Unique: Exposes Hetzner's list/describe APIs through MCP's structured tool interface with filtering support, allowing LLMs to query infrastructure state conversationally and make informed decisions about resource management
vs alternatives: More accessible than direct API calls for LLMs; simpler than setting up monitoring dashboards for one-off queries
Provides MCP tools for listing available server images (OS distributions), creating snapshots from running servers, and using snapshots as templates for new server creation. Enables infrastructure-as-code workflows where servers can be configured once and then cloned via snapshots. Supports filtering images by OS type, architecture, and availability.
Unique: Integrates Hetzner's image and snapshot APIs into MCP's tool interface, enabling LLMs to reason about infrastructure templates and automate golden image workflows
vs alternatives: More flexible than Terraform for dynamic snapshot-based scaling; simpler than Packer for one-off image creation
Implements the Model Context Protocol (MCP) server specification, exposing all Hetzner Cloud operations as structured tool definitions with JSON schemas. The server handles MCP request/response serialization, tool discovery, and error handling. Tools are defined with input schemas (parameter types, validation rules) and output schemas (response structure), enabling LLM clients to understand and invoke operations correctly.
Unique: Implements MCP server specification to expose Hetzner Cloud as native LLM tools, standardizing the interface across different LLM platforms and clients rather than requiring custom integrations for each
vs alternatives: More standardized than custom API wrappers; enables broader LLM client compatibility than platform-specific integrations
Executes HTTP requests to APIs protected by HTTP 402 Payment Required status codes, automatically detecting payment requirements and routing requests through the MCP server's payment settlement layer. The server intercepts 402 responses, extracts payment metadata (amount, recipient, token), and initiates on-chain USDC micropayments on Base L2 before retrying the original request with proof-of-payment headers. This enables seamless agent-to-API interactions without manual payment handling or custodial intermediaries.
Unique: Implements transparent HTTP 402 payment interception at the MCP protocol layer, allowing any MCP-compatible agent (Claude, LangChain, CrewAI) to access paid APIs without SDK changes or wallet management code. Uses Base L2 for sub-cent settlement costs and non-custodial architecture where agents control their own signing keys rather than delegating to a payment processor.
vs alternatives: Unlike Cloudflare Pay-Per-Crawl (proprietary, Cloudflare-only) or Tollbit (requires API provider integration), works on any host and settles directly on-chain with zero platform fees, giving agents true ownership of payment flows.
Manages cryptographic signing and submission of USDC transfers to Base L2 blockchain without holding agent private keys or funds in escrow. The server accepts payment requests with recipient address and amount, constructs ERC-20 transfer transactions, signs them using the agent's provided key material (or external signer), and broadcasts to Base L2 RPC. Settlement completes on-chain with full transparency and auditability, with no platform-controlled custody or fee extraction.
Unique: Implements non-custodial payment settlement where the MCP server never holds or controls agent funds — only constructs and signs transactions using agent-provided key material. Uses Base L2 instead of mainnet Ethereum to achieve sub-cent transaction costs (~$0.001 per transfer) while maintaining full on-chain settlement and auditability.
Eliminates counterparty risk vs custodial payment processors (Stripe, PayPal) by settling directly on-chain; cheaper than mainnet Ethereum by 100-1000x due to Base L2 rollup architecture; more transparent than traditional APIs with hidden fees.
@xenarch/agent-mcp scores higher at 30/100 vs Hetzner Cloud MCP Server at 26/100. Hetzner Cloud MCP Server leads on adoption, while @xenarch/agent-mcp is stronger on quality and ecosystem.

Maintains immutable transaction history of all USDC payments and API calls, logging transaction hash, timestamp, amount, recipient, and HTTP request/response details. The server stores logs in a queryable format (JSON, database) accessible through MCP tools, enabling agents and operators to audit spending, debug failed payments, and reconstruct payment flows. Logs include both on-chain transaction data and off-chain HTTP metadata.
Unique: Maintains unified transaction history combining on-chain USDC transfers with off-chain HTTP metadata, enabling full-stack audit trails. Logs are queryable through MCP tools, allowing agents to access their own transaction history without external tools.
vs alternatives: More comprehensive than blockchain-only transaction history by including HTTP request/response details; more accessible than requiring manual blockchain queries.
Provides centralized configuration for payment parameters (USDC amount, recipient address, spending limits), API endpoint mappings, and RPC provider settings. Configuration is loaded from environment variables, JSON files, or environment-specific profiles, allowing operators to adjust payment rules without restarting the MCP server. Supports hot-reloading of configuration changes for zero-downtime updates.
Unique: Centralizes payment and RPC configuration in a single source of truth with support for environment-specific profiles and hot-reloading. Allows operators to adjust payment rules without code changes or server restarts.
vs alternatives: More flexible than hardcoded payment parameters; simpler than requiring agents to manage configuration themselves.
Exposes HTTP 402 payment handling and USDC settlement as MCP tools that Claude, Cursor, LangChain, and CrewAI can discover and invoke through the standard Model Context Protocol. The server implements MCP tool schema definitions for payment-gated requests and settlement operations, allowing agents to treat paid API access as first-class capabilities alongside native tools. Integration requires no agent-side SDK changes — agents interact via standard MCP tool-calling semantics.
Unique: Implements MCP as the primary integration surface, allowing agents to access paid APIs through standard tool-calling semantics without SDK-specific code. Supports multiple agent frameworks (Claude, Cursor, LangChain, CrewAI) through a single MCP server, reducing integration surface area and enabling cross-framework agent composition.
vs alternatives: More flexible than framework-specific SDKs because MCP is protocol-agnostic; agents can switch frameworks without rewriting payment logic. Simpler than building custom API wrappers for each agent framework.
Intercepts HTTP responses with 402 Payment Required status codes and extracts payment metadata from response headers (x402-amount, x402-recipient, x402-token) to determine payment requirements. The server parses metadata, validates format and values, and automatically initiates payment settlement without requiring the agent to manually inspect headers or construct payment requests. This enables transparent payment handling where agents see paid API access as a seamless extension of normal HTTP requests.
Unique: Implements automatic 402 detection at the HTTP layer with strict metadata parsing, allowing agents to treat payment-gated APIs identically to free APIs. Uses header-based metadata (x402-*) rather than response body parsing, enabling payment requirements to be communicated without changing API response schemas.
vs alternatives: More transparent than requiring agents to check response status codes manually; more flexible than hardcoding payment amounts per API endpoint.
Manages payment state and context across multiple agent frameworks (Claude, LangChain, CrewAI) executing in the same workflow, ensuring consistent wallet management, balance tracking, and transaction history. The server maintains a unified payment ledger accessible to all agents, preventing double-spending and enabling cross-agent payment coordination. Agents can query remaining balance, transaction history, and payment status through MCP tools without framework-specific code.
Unique: Implements a unified payment ledger that abstracts away framework differences, allowing Claude, LangChain, and CrewAI agents to coordinate on shared payment budgets without framework-specific integration code. Maintains consistent state across heterogeneous agent types through a single MCP interface.
vs alternatives: Simpler than building separate payment systems for each framework; enables true multi-agent coordination vs isolated per-framework payment handling.
Generates cryptographic proof-of-payment headers (e.g., transaction hash, signature) after successful USDC settlement and attaches them to retry requests, allowing target APIs to verify that payment was completed. The server constructs headers containing transaction hash, block number, and optional signature proof, which APIs can validate against Base L2 blockchain state. This enables APIs to trust that payment occurred without querying the blockchain themselves.
Unique: Generates lightweight proof-of-payment headers that APIs can validate without querying the blockchain, reducing latency for payment verification. Uses transaction hash and block number as proof, with optional cryptographic signatures for stronger guarantees.
vs alternatives: Faster than requiring APIs to query blockchain for every payment; more trustworthy than relying on MCP server claims alone if signatures are included.
