+
+# Power Platform MCP Connector Generator
+
+Generate a complete Power Platform custom connector with Model Context Protocol (MCP) integration for Microsoft Copilot Studio. This prompt creates all necessary files following Power Platform connector standards with MCP streamable HTTP support.
+
+## Instructions
+
+Create a complete MCP server implementation that:
+
+1. **Uses Copilot Studio MCP Pattern:**
+   - Implement `x-ms-agentic-protocol: mcp-streamable-1.0`
+   - Support JSON-RPC 2.0 communication protocol
+   - Provide streamable HTTP endpoint at `/mcp`
+   - Follow Power Platform connector structure
+
+2. **Schema Compliance Requirements:**
+   - **NO reference types** in tool inputs/outputs (filtered by Copilot Studio)
+   - **Single type values only** (not arrays of multiple types)
+   - **Avoid enum inputs** (interpreted as string, not enum)
+   - Use primitive types: string, number, integer, boolean, array, object
+   - Ensure all endpoints return full URIs
+
+3. **MCP Components to Include:**
+   - **Tools**: Functions for the language model to call (✅ Supported in Copilot Studio)
+   - **Resources**: File-like data outputs from tools (✅ Supported in Copilot Studio - must be tool outputs to be accessible)
+   - **Prompts**: Predefined templates for specific tasks (❌ Not yet supported in Copilot Studio)
+
+4. **Implementation Structure:**
+   ```
+   /apiDefinition.swagger.json  (Power Platform connector schema)
+   /apiProperties.json         (Connector metadata and configuration)
+   /script.csx                 (Custom code transformations and logic)
+   /server/                    (MCP server implementation)
+   /tools/                     (Individual MCP tools)
+   /resources/                 (MCP resource handlers)

+# Power Platform MCP Connector Suite
+
+Generate comprehensive Power Platform custom connector implementations with Model Context Protocol integration for Microsoft Copilot Studio.
+
+## MCP Capabilities in Copilot Studio
+
+**Currently Supported:**
+- ✅ **Tools**: Functions that the LLM can call (with user approval)
+- ✅ **Resources**: File-like data that agents can read (must be tool outputs)
+
+**Not Yet Supported:**
+- ❌ **Prompts**: Pre-written templates (prepare for future support)
+
+## Connector Generation
+
+Create complete Power Platform connector with:
+
+**Core Files:**
+- `apiDefinition.swagger.json` with `x-ms-agentic-protocol: mcp-streamable-1.0`
+- `apiProperties.json` with connector metadata and authentication
+- `script.csx` with custom C# transformations for MCP JSON-RPC handling
+- `readme.md` with connector documentation
+
+**MCP Integration:**
+- POST `/mcp` endpoint for JSON-RPC 2.0 communication
+- McpResponse and McpErrorResponse schema definitions
+- Copilot Studio constraint compliance (no reference types, single types)
+- Resource integration as tool outputs (Resources and Tools supported; Prompts not yet supported)
+
+## Schema Validation & Troubleshooting
+
+**Validate schemas for Copilot Studio compliance:**
+- ✅ No reference types (`$ref`) in tool inputs/outputs
+- ✅ Single type values only (not `["string", "number"]`)
+- ✅ Primitive types: string, number, integer, boolean, array, object
+- ✅ Resources as tool outputs, not separate entities
+- ✅ Full URIs for all endpoints
+
+**Common issues and fixes:**
+- Tools filtered → Remove reference types, use primitives
+- Type errors → Single types with validation logic
+- Resources unavailable → Include in tool outputs
+- Connection failures → Verify `x-ms-agentic-protocol` header
