+# MCP-based M365 Agents Collection
+
+A comprehensive collection of prompts and instructions for building declarative agents with Model Context Protocol (MCP) integration for Microsoft 365 Copilot.
+
+## Overview
+
+The Model Context Protocol (MCP) is a universal standard that allows AI models to integrate with external systems through standardized server endpoints. This collection provides everything you need to build, deploy, and manage MCP-based declarative agents that extend Microsoft 365 Copilot with custom capabilities.
+
+## What is Model Context Protocol?
+
+MCP is an open protocol developed to streamline how AI models connect to external data sources and tools. Instead of custom integration code for each system, MCP provides a consistent interface for:
+
+- **Server Metadata**: Discover available tools and capabilities
+- **Tools Listing**: Get function definitions and schemas
+- **Tool Execution**: Invoke tools with parameters and receive results
+
+For Microsoft 365 Copilot, this means you can create agents that connect to any MCP-compatible server with point-and-click configuration instead of writing custom code.
+
+## Collection Contents
+
+### Prompts
+
+1. **Create Declarative Agent** ([mcp-create-declarative-agent.prompt.md](prompts/mcp-create-declarative-agent.prompt.md))

+
+3. **Deploy and Manage Agents** ([mcp-deploy-manage-agents.prompt.md](prompts/mcp-deploy-manage-agents.prompt.md))
+   - Deploy agents via Microsoft 365 admin center

+   - Monitor agent usage and performance
+
+### Instructions
+
+**MCP M365 Copilot Development Guidelines** ([mcp-m365-copilot.instructions.md](instructions/mcp-m365-copilot.instructions.md))
+- Best practices for MCP server design and tool selection
+- File organization and project structure
+- Response semantics configuration patterns
+- Adaptive Card design principles
+- Security, governance, and compliance requirements
+- Testing and deployment workflows
+
+## Key Concepts
+
+### Declarative Agents
+
+Declarative agents are defined through configuration files rather than code:
+- **declarativeAgent.json**: Agent instructions, capabilities, conversation starters
+- **ai-plugin.json**: MCP server tools, response semantics, adaptive card templates
+- **mcp.json**: MCP server URL, authentication configuration
+- **manifest.json**: Teams app manifest for packaging
+
+### MCP Server Integration
+
+The Microsoft 365 Agents Toolkit provides a visual interface for:
+1. **Scaffold** a new agent project
+2. **Add MCP action** to connect to a server
+3. **Choose tools** from the server's available functions
+4. **Configure authentication** (OAuth 2.0, SSO)
+5. **Generate files** (agent config, plugin manifest)
+6. **Test** in m365.cloud.microsoft/chat
+
+### Authentication Patterns
+
+**OAuth 2.0 Static Registration:**
+- Pre-register OAuth app with service provider
+- Store credentials in .env.local (never commit)
+- Reference in ai-plugin.json authentication config
+- Users consent once, tokens stored in plugin vault
+
+**Single Sign-On (SSO):**
+- Use Microsoft Entra ID for authentication
+- Seamless experience for M365 users
+- No separate login required
+- Ideal for internal organizational agents
+
+### Response Semantics
+
+Extract and format data from MCP server responses:
+
+```json
+{
+  "response_semantics": {
+    "data_path": "$.items[*]",
+    "properties": {
+      "title": "$.name",
+      "subtitle": "$.description",
+      "url": "$.html_url"
+    },
+    "static_template": { ... }
+  }
+}
+```
+
+- **data_path**: JSONPath to extract array or object
+- **properties**: Map response fields to Copilot properties
+- **template_selector**: Choose dynamic template based on response
+- **static_template**: Adaptive Card for visual formatting
+
+### Adaptive Cards
+
+Rich visual responses for agent outputs:
+
+**Static Templates:**
+- Defined once in ai-plugin.json
+- Used for all responses with same structure
+- Better performance and easier maintenance
+
+**Dynamic Templates:**
+- Returned in API response body
+- Selected via template_selector JSONPath
+- Useful for varied response structures
+
+**Template Language:**
+- `${property}`: Data binding
+- `${if(condition, true, false)}`: Conditionals
+- `${formatNumber(value, decimals)}`: Formatting
+- `$when`: Conditional element rendering
+
+## Deployment Options
+
+### Organization Deployment
+- IT admin deploys to all users or specific groups
+- Requires approval in Microsoft 365 admin center
+- Best for internal business agents
+- Full governance and compliance controls
+
+### Agent Store
+- Submit to Partner Center for validation
+- Public availability to all Copilot users
+- Rigorous security and compliance review
+- Suitable for partner-built agents
+
+## Partner Examples

+- Create tasks directly from Copilot
+- Query project status and updates
+- Assign work items to team members
+- View deadlines and milestones
+

+## Best Practices
+
+### MCP Server Design
+- Import only necessary tools (avoid over-scoping)
+- Use secure authentication (OAuth 2.0, SSO)
+- Test each tool individually
+- Validate server endpoints are HTTPS
+- Consider token limits when selecting tools
+
+### Agent Instructions

+- Set boundaries for what agent can/cannot do
+- Use conversation starters to guide users
+
+### Response Formatting
+- Use JSONPath to extract relevant data

+- Test cards across Copilot surfaces (Chat, Teams, Outlook)
+
+### Security and Governance
+- Never commit credentials to source control
+- Use environment variables for secrets
+- Follow principle of least privilege
+- Review compliance requirements
+- Monitor agent usage and performance
