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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00591 |
| Opus 5.5 | $0.00000 | $0.00236 |
| Sonnet 5.5 | $0.00000 | $0.00118 |
| Haiku 4.5 | $0.00000 | $0.00059 |
Grade A, and why
strapi-plugin-development 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 2mo 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.

Strapi Plugin Development Guidelines
Plugin Registration
- Plugin registration happens in admin/src/index.ts
- Plugin ID is defined in admin/src/pluginId.ts as 'mcp'
- Menu links are added during registration with proper internationalization
Strapi v5 Plugin Architecture
- Dual export system: admin and server components are separate
- Admin components use React and Strapi Design System
- Server components follow Strapi's controller/service/route pattern
Admin Panel Integration
- Use
@strapi/design-systemcomponents for consistent UI - Follow Strapi's admin panel patterns for navigation and layout
- Implement proper internationalization using admin/src/translations/
API Development
- Controllers should be thin and delegate to services
- Use Strapi's built-in validation and error handling
- Follow RESTful API conventions
- Example structure in server/src/controllers/events.controller.ts
Service Layer
- Business logic belongs in services (server/src/services/)
- Services can access Strapi's core functionality
- Use dependency injection where possible
- Example: server/src/services/contentTypes.service.ts
Plugin Configuration
- Plugin metadata is defined in package.json under the "strapi" key
- Plugin kind is set to "plugin"
- Display name and description should be meaningful
Build and Distribution
- Use
@strapi/sdk-pluginfor building - Built files go to
dist/directory - Both CommonJS and ESM formats are supported
- TypeScript declarations are generated automatically
Testing
- Type checking:
pnpm test:ts:frontandpnpm test:ts:back - Plugin verification:
pnpm verify - Manual testing in development:
pnpm watch
MCP Integration Specifics
- This plugin integrates Model Context Protocol functionality
- Uses
@modelcontextprotocol/sdkfor MCP operations - Provides content type introspection and system information
- Handles MCP events through dedicated controllers
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.

strapi-plugin-development is a cursor rule published in the GitHub repository VirtusLab-Open-Source/strapi-plugin-mcp (3 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 591 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.
