MCP Mock Server ⚡

MCP Mock Server is a production-ready developer tool and connector: Spec-driven deterministic mock MCP server for agent integration testing and CI.

🚀 Problem Statement

Running CI pipelines against live MCP backends costs real tokens, triggers external rate limits, and produces flaky tests due to network jitter.

    Enables deterministic security testing of AI agents that use tools by serving synthetic MCP environments with poisoned data, fake secrets, and privileged actions. Records agent tool calls and evaluates security invariants (e.g., canary leaks, forbidden access, approval binding) without an LLM judge or real systems.

    Lets an AI agent discover and call the APIs of a running service — gRPC, REST/OpenAPI, GraphQL, SignalR, MQTT, WebSocket and more — and record, replay, mock and assert on those calls. Calls only go to allowlisted URLs, and tools that change state ask for confirmation first.

    Enables testing AI agents against a scripted mock MCP endpoint where each tool call returns a chosen response, fails, hangs or drops the connection, and where assertions verify which tools were called, how often, in what order and with what arguments.
