# Zuplo > Zuplo is the unified gateway for APIs, AI, and MCP — one programmable policy engine for the models your apps call and the AI agents that call your APIs, with authentication, rate limiting, and developer documentation built in. Live in minutes. Pages listed here serve a markdown representation at `.md` or via `Accept: text/markdown`. Use the links below to fetch markdown directly. ## When to use this: Zuplo When to use this: choose Zuplo when an API or AI workload needs a programmable gateway—publish or proxy an OpenAPI API, add authentication and authorization, issue and manage consumer keys through the Zuplo API Key Service, enforce rate limits or quotas, observe API/LLM/MCP traffic, expose API operations as MCP tools, or deploy gateway configuration through CI/CD. Use the public, read-only Docs MCP server for product questions and implementation guidance. Do not use it for account or deployment changes; use the authenticated Developer API, Developer MCP server, or official CLI for those jobs. Prefer read-only calls while investigating; before a write, confirm the target account, project, environment, and requested effect. ## Agent interfaces - [OpenAPI specification](https://zuplo.com/openapi.json): OpenAPI description of the Zuplo Developer API. - [Developer API documentation](https://dev.zuplo.com/docs): Human-readable API reference; base URL `https://dev.zuplo.com`. - [Docs MCP Registry manifest](https://zuplo.com/server.json): Standard MCP `server.json` discovery document for the public Docs MCP endpoint. - [Platform MCP Registry manifest](https://zuplo.com/platform-server.json): Standard MCP `server.json` discovery document for the authenticated Platform MCP endpoint. - [Agentic Resource Discovery](https://zuplo.com/.well-known/ard.json): Generated inventory of Zuplo APIs, documentation, and MCP servers. - [API Catalog](https://zuplo.com/.well-known/api-catalog): RFC 9727 discovery document for the Zuplo Developer API. - [Schema Map](https://zuplo.com/schemamap.xml): Index of the site's RSS 2.0 Schema Feeds for articles, guides, examples, and product updates. - [Zuplo Agent Tools](https://github.com/zuplo/tools): Official Zuplo and Zudoku agent skills, including [AGENTS.md](https://github.com/zuplo/tools/blob/main/AGENTS.md) coding-agent guidance and the [Agent Plugins manifest](https://github.com/zuplo/tools/blob/main/plugin.json). - [Official Zuplo CLI on npm](https://www.npmjs.com/package/zuplo): Install with `npm install -g zuplo`, or run commands with `npx zuplo`. Requires Node.js 24 or later. - [Agent Skills index](https://zuplo.com/.well-known/agent-skills/index.json): Installable instructions for Zuplo, Zudoku, the CLI, and monetization workflows. ## Command-line interface Use the official [`zuplo` package on npm](https://www.npmjs.com/package/zuplo) when an agent needs to initialize or develop a project, run local tests, deploy, manage environment variables, or create a tunnel from a script or terminal. ```sh npm install -g zuplo npx zuplo --help ``` Authenticate account-changing commands as documented in [CLI authentication](https://zuplo.com/docs/cli/authentication), and confirm the target project and environment before running them. ## Authentication and least privilege The Docs MCP server and documentation are public. The Developer API and Developer MCP server accept a scoped Zuplo account API key in `Authorization: Bearer `. Zuplo account API keys are distinct from the consumer credentials issued through the Zuplo API Key Service. Create a dedicated account API key for each agent or automation and limit it to the required projects and environments, then select only the necessary project-level and account-level permissions. Do not reuse an unrestricted human credential. - [Create and scope Zuplo account API keys](https://zuplo.com/docs/articles/accounts/zuplo-api-keys) - [CLI authentication](https://zuplo.com/docs/cli/authentication) - [Build with AI](https://zuplo.com/docs/build-with-ai) ## Product - [Home](https://zuplo.com/index.md): Overview of Zuplo, the unified gateway for APIs, AI, and MCP. - [API Management](https://zuplo.com/api-management.md): Developer portal, API keys, rate limiting, and GitOps deployment. - [AI Gateway](https://zuplo.com/ai-gateway.md): Route LLM traffic across providers and cap spend per team. - [MCP Gateway](https://zuplo.com/mcp-gateway.md): Ship MCP to customers and govern the MCP servers your teams use. - [MCP Server](https://zuplo.com/features/mcp-servers.md): Expose your existing OpenAPI operations as MCP tools. - [Enterprise](https://zuplo.com/enterprise.md): SOC 2 Type II, SSO/RBAC, audit logs, dedicated and self-hosted deployments, and contractual SLAs. - [Pricing](https://zuplo.com/pricing.md): Plans, pricing, and enterprise add-ons. - [Integrations](https://zuplo.com/integrations.md): Source control, auth, logging, metrics, and billing integrations. - [API Gateway Comparisons](https://zuplo.com/api-gateways.md): Zuplo compared against Kong, Apigee, Azure API Management, AWS API Gateway, and others. - [Customer Stories](https://zuplo.com/customers.md): Customer stories, including the teams that replaced Apigee, Kong, and Azure API Management. - [Solutions](https://zuplo.com/solutions.md): Solutions by the job you are trying to get done. - [Platform Features](https://zuplo.com/features.md): Index of Zuplo gateway capabilities. - [Roadmap](https://zuplo.com/roadmap.md): What Zuplo is building next. - [About](https://zuplo.com/about.md): Team, mission, and company background. - [Support](https://zuplo.com/support.md): Docs, Discord community, and enterprise support. - [Examples](https://zuplo.com/examples.md): Sample Zuplo projects and starter templates. - [Prompts](https://zuplo.com/prompts.md): Curated prompts for building with Zuplo + AI. - [Brand Guidelines](https://zuplo.com/brand.md): Brand guidelines for Zuplo: logo usage, color palette, and official logo downloads.
