Simceptor — AI-Native Mock API Server for Modern Development Teams Simceptor is a cloud-based mock API platform built from the ground up for AI-assisted development workflows. With 26 MCP tools, your AI coding assistant (Claude, Cursor, Windsurf, etc.) can create, configure, and manage your entire mock API layer — no dashboard clicking required. 🤖 Set Up Mock APIs Directly via MCP Simply tell your AI agent: "Create a POST /payments endpoint that returns a 200 success response." Simceptor's MCP integration handles the rest — from creating the endpoint to configuring response bodies, headers, and status codes, all in seconds through natural language. ⚡ Powerful Rule Engine Go beyond static mocks. Define conditional response rules based on request headers, body fields, query params, or path variables. Return different responses depending on the input — simulate edge cases, error states, and complex branching logic without writing a single line of server code. 🔄 Stateful API Simulation Simulate real-world stateful flows such as order lifecycles, authentication sequences, or multi-step checkout processes. Simceptor maintains session state across requests, letting you mock workflows that evolve over time — critical for end-to-end testing and demos. 📡 Webhook Support Configure your mock endpoints to fire outbound webhook calls upon being triggered. Test how your services react to external events without needing a real third-party system in the loop. 🧠 AI-Powered Issue Tracker When your mock doesn't behave as expected, raise an issue directly from the dashboard. Your AI agent can then read the issue, analyze the current mock configuration, apply a fix, and automatically mark it resolved — closing the feedback loop between humans and AI in your development cycle. Perfect for backend developers, QA engineers, and platform teams who want to move fast without waiting for real APIs to be ready. 🔗 simceptor.com
