ReAPI OpenAPISAFE
OpenAPI specification MCP server.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
A Model Context Protocol (MCP) server that loads and serves multiple OpenAPI specifications to enable LLM-powered IDE integrations. This server acts as a bridge between your OpenAPI specifications and LLM-powered development tools like Cursor and other code editors.
Features
- Loads multiple OpenAPI specifications from a directory
- Exposes API operations and schemas through MCP protocol
- Enables LLMs to understand and work with your APIs directly in your IDE
- Supports dereferenced schemas for complete API context
- Maintains a catalog of all available APIs
Powered by ReAPI
This open-source MCP server is sponsored by ReAPI, a next-generation API platform that simplifies API design and testing. While this server provides local OpenAPI integration for development, ReAPI offers two powerful modules:
🎨 API CMS
- Design APIs using an intuitive no-code editor
- Generate and publish OpenAPI specifications automatically
- Collaborate with team members in real-time
- Version control and change management
🧪 API Testing
- The most developer-friendly no-code API testing solution
- Create and manage test cases with an intuitive interface
- Powerful assertion and validation capabilities
- Serverless cloud test executor
- Perfect for both QA teams and developers
- CI/CD integration ready

Cursor Configuration
To integrate the MCP OpenAPI server with Cursor IDE, you have two options for configuration locations:
Option 1: Project-specific Configuration (Recommended)
Create a .cursor/mcp.json file in your project directory. This option is recommended as it allows you to maintain different sets of specs for different projects

Questions
What is the ReAPI OpenAPI MCP server?
OpenAPI specification MCP server.
What tools does ReAPI OpenAPI expose?
8 in total: 8 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is ReAPI OpenAPI safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does ReAPI OpenAPI need?
No credential environment variables were found in its source, so it appears to need none.
How does ReAPI OpenAPI run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @reapi/mcp-openapi at 0.0.4.
How current is this page?
The grade is for one exact copy of the source (3a1a6debda23), read on 2026-10-07. The repository is watched and re-audited when it changes.
