How to Use the Builder MCP in Windsurf

Q: How do I connect the Builder MCP Server to Windsurf?

Open your /.codeium/windsurf/mcpconfig.json file and add the MCP config under the mcpServers key. Cascade automatically detects the new tools like listbuildermodels upon saving the file.

Q: How does Cascade use the Builder server to fix rendering errors in Windsurf?

Cascade runs getsinglecontent to fetch the exact JSON payload causing the crash. Then, your agent analyzes the mismatch against your local React code and rewrites the component to handle the missing fields.

Q: Can I bulk delete test blocks?

Yes. Tell Cascade to find test entries using searchactivemodels and purge them. The agent will loop through the results and run wipevisualblock on each matching ID.

Stop manually copying schemas; let Windsurf autonomously build and sync your Builder CMS components in Cascade.

Auto-generate code from Builder schemas in Windsurf

The `get_model_schema` tool pulls your exact Builder.io field structure straight into Cascade. Cascade reads this JSON definition, plans the TypeScript types, and writes matching React frontend components in your workspace. This MCP Server lets your agent inspect schemas, write the UI, and verify the types match your CMS fields in one autonomous run. You do not need to copy-paste field names or guess types anymore.

Deploy visual blocks directly from the Cascade panel

The `create_visual_block` tool lets Windsurf write and push fresh content blocks directly to your Builder space. Cascade handles the API payload, creates the block, and updates your local mock data to match the new CMS state. If you need to make changes, Cascade runs `update_visual_block` to patch existing documents. You get a live sync between your local codebase and your headless CMS without opening a browser tab.

Validate live CMS data inside your Windsurf workspace

The `list_model_content` tool retrieves your live Builder entries so Cascade can run unit tests against actual production payloads. Your agent compares the CMS output with your local component props to catch rendering bugs before you commit. It uses `count_model_entities` to verify your content migrations succeeded. You get immediate confirmation that your database counts match your CMS expectations inside your favorite editor.

Open your `~/.codeium/windsurf/mcp_config.json` file and add the MCP config under the `mcpServers` key. Cascade automatically detects the new tools like `list_builder_models` upon saving the file.

No, this server focuses on content and block management. It uses `get_model_schema` to inspect your structure, but it cannot alter the schema definitions themselves. It can only write and update content blocks using `update_visual_block`.

Cascade runs `get_single_content` to fetch the exact JSON payload causing the crash. Then, your agent analyzes the mismatch against your local React code and rewrites the component to handle the missing fields.

Yes. Tell Cascade to find test entries using `search_active_models` and purge them. The agent will loop through the results and run `wipe_visual_block` on each matching ID.

No, all API calls to Builder.io go through Vinkius's secure MCP sandbox directly to the CMS endpoints. Your visual blocks, media metadata, and schema structures are never stored or logged on our servers.
