Nue MCP Servers Overview

model context protocol (mcp) is an open specification (originally from anthropic https //www anthropic com/ ) that standardizes how ai models and agents connect to external tools — business logic, data sources, and services — through a simple request/response interface over http or streaming transports mcp allows ai clients to reliably discover available tools , call them with structured parameters , and receive structured results assistants can interact with real systems in a predictable, secure, and verifiable way, rather than relying solely on ungrounded natural language prompts why mcp matters by separating model specific behavior from tool execution, mcp allows organizations to keep domain logic in one place and reuse it across multiple llms (e g , openai, anthropic, gemini) and agent runtimes this reduces integration friction, avoids model lock in, and makes ai integrations more scalable and maintainable mcp server the tool execution layer an mcp server is any service that implements the model context protocol https //www anthropic com/news/model context protocol and exposes one or more named tools — each with clear descriptions and input schemas — that ai clients can call at runtime, the mcp server acts as the execution layer it tells clients which tools are available, authenticates and authorizes incoming requests, runs the requested business logic (e g , calling apis, querying databases), and streams back structured results the server itself remains model agnostic — it doesn't depend on a specific llm all model specific reasoning happens on the client side key responsibilities of an mcp server advertise available tools to clients (including name, description, and parameter schema) for safe discovery receive structured tool calls over json rpc or streaming http/sse, execute the underlying logic, and return results or errors in a predictable format enforce authentication and authorization , ensuring the right data and tools are accessible with the right scope mcp client the ai integration layer an mcp client runs inside your ai application or agent framework it connects to one or more mcp servers, retrieves their tool definitions, and makes them available to the model as part of its prompt and function calling context when the model chooses to call a tool, the mcp client translates that intent into a structured request (e g , http/sse), manages retries and timeouts, and streams the response back to the model for further reasoning the nue mcp gateway beta the nue mcp gateway is in beta its built in servers and tools may evolve nue exposes its revenue platform through a single mcp endpoint — the nue mcp gateway — that federates a set of specialized, domain focused servers behind one authenticated connection you connect once (see connecting to nue mcp docid\ h6afi jeh6817ew0vd13w ); the gateway advertises the combined tool set, routes each call to the right server, and namespaces tools per server (e g lcm , nuedocs , pricebuilder ) so they never collide nue environment gateway endpoint nue production https //mcp nue io/mcp nue sandbox https //mcp sandbox nue io/mcp built in servers (on by default) three servers are built into the gateway and enabled by default — connect once and they're ready, no extra setup server coverage status nue lifecycle manager docid\ cf8cbhygypd3ozg7ym2gy opportunities · quotes · orders · subscriptions · renewals · invoices · credit memos default on · beta nue docs docid\ dplnzhfzgeltbursolbu2 search & read the knowledge center and rest api reference default on nue price builder docid\ vmvbd0nkai8uvh0rkvyls products · pricing rules · bundles · pricing plugins · sku config default on · beta more domains are on the roadmap server coverage status nue billing & collections 🚧 invoices · payments · credits · dunning · collections coming soon nue admin 🚧 system settings & configuration · data imports & exports · webhooks coming soon analytics 🚧 arr · mrr · churn · forecasting · revenue insights roadmap you can also add your own external mcp servers docid\ tassmkgq9g 37sfc0hzjz — sigma, gong, fellow, or any mcp compliant tool — so nue's agents (and your own) can reach into the rest of your stack built in servers are always on;
