mcp-integration

Integration rules for adding Model Context Protocol support to a Strapi plugin. They describe services that expose content types, system information, plugin status, and event handling to AI tools.

In plain words
What is it for?
For implementing and reviewing MCP services, event controllers, schemas, dependencies, and secure communication in Strapi.
Why use it?
They set expectations for protocol messages, validation, authentication, authorization, and error handling when AI software accesses Strapi.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Model Context Protocol (MCP) Integration Guidelines

MCP Overview

This plugin integrates Model Context Protocol functionality into Strapi, enabling AI models to interact with Strapi content and system information.

Core MCP Dependencies

  • @modelcontextprotocol/sdk - Primary SDK for MCP functionality
  • zod - Schema validation for MCP data structures

MCP Service Architecture

Content Types Service (server/src/services/contentTypes.service.ts)

  • Provides introspection of Strapi content types
  • Exposes content type schemas and relationships
  • Handles content type metadata for MCP clients

Strapi Info Service (server/src/services/strapiInfo.service.ts)

  • Exposes Strapi system information
  • Provides version and configuration details
  • Offers plugin and system status information

Events Controller (server/src/controllers/events.controller.ts)

  • Handles MCP event processing
  • Manages communication between MCP clients and Strapi
  • Processes MCP requests and responses

MCP Protocol Implementation

  • Follow MCP specification for message formats
  • Use proper error handling for MCP operations
  • Implement appropriate authentication and authorization
  • Ensure data validation using Zod schemas

Data Exposure Guidelines

  • Only expose necessary Strapi information through MCP
  • Implement proper access controls for sensitive data
  • Validate all incoming MCP requests
  • Sanitize data before sending to MCP clients

Error Handling for MCP

  • Use MCP-compliant error formats
  • Provide meaningful error messages
  • Log MCP-related errors for debugging
  • Handle network and protocol errors gracefully

Security Considerations

  • Validate all MCP inputs
  • Implement rate limiting for MCP endpoints
  • Use proper authentication mechanisms
  • Audit MCP operations for security compliance

Testing MCP Integration

  • Test MCP protocol compliance
  • Verify data integrity in MCP responses
  • Test error scenarios and edge cases
  • Validate performance under load

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mcp-integration is a cursor rule published in the GitHub repository VirtusLab-Open-Source/strapi-plugin-mcp (3 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 497 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
