# CodeStencil > Help center and documentation for CodeStencil ## FAQ - Q: Does the Trial Version have some Pro features locked? A: The 30-day Trial version has **all features enabled**. After the trial expires, the application will continue to function and your data intact only that the Pro features will be disabled at that time. - Q: How do I switch my database from Sqlite to Sql Server? A: Depending on the stencil you are using, if it generates code that supports multiple databases, then that is easy to do. See: [Set Node To Specific Database](https://codestencil.com/docs/index.html?cs_set-node-to-specific-database.htm) and [Swapping Databases](https://codestencil.com/docs/index.html - Q: Running the app the first time, I get a message that it has already expired. A: It is common to install an application and not get to try it immediately. Nevertheless, we are happy to extend the license period for you. Just send a request to support@codestencil.com with your name and email and we will send you an extended license. - Q: Generated code requires entry for primary key (which is Identity and auto-incremented) A: If you don't want to expose your primary (auto-incremented) key to data entry, all you need to do is to switch off that column in the Database Schema panel. - Q: The stencil I used has the Chinook database as a demo, how do I replace this with my own? A: You can swap out a existing Database schema with your own by using the [Schema Importer](https://codestencil.com/docs/index.html?cs_schema-importer.htm). ## Search For specific questions, search: https://app.helpshelf.com/help/www-159/search?q={query} ## AI Agent Access - [Full product context](https://app.helpshelf.com/help/www-159/llms-full.txt): policy-checked verified documentation, or guarded-access guidance when bulk export is unavailable - MCP endpoint: https://app.helpshelf.com/api/mcp/2c5f5adfbd28 (streamable HTTP) with tools: search_docs, ask, get_article, get_product_context Send `Accept: application/json, text/event-stream` — a compliant Streamable HTTP server answers 406 without both media types. - [MCP server card](https://app.helpshelf.com/help/www-159/.well-known/mcp/server-card.json): machine-readable description of the endpoint above - [Agent skills](https://app.helpshelf.com/help/www-159/.well-known/agent-skills/index.json): how to use this documentation, as an Agent Skill - Markdown: any article URL returns Markdown when requested with `Accept: text/markdown` AI agents have read-only access to published documentation.
