# Ticket: Learn and Encode MCP Concepts

## Ticket Information

- **ID**: TICKET-028
- **Title**: Learn and Encode MCP Concepts into Architecture
- **Type**: Research
- **Priority**: High
- **Status**: Done
- **Track**: Tools/MCP
- **Milestone**: Milestone 1 - Survey & Architecture
- **Created**: 2024-01-XX

## Description

Learn Model Context Protocol (MCP) and integrate into architecture:
- Understand MCP concepts: hosts, clients, servers
- Tools/call and tools/list endpoints
- JSON-RPC protocol
- Architecture integration

## Acceptance Criteria

- [x] MCP concepts understood and documented
- [x] Architecture updated with MCP components
- [x] Protocol details documented (JSON-RPC 2.0)
- [x] Integration points identified (LLM hosts, MCP adapter, MCP server)

## Technical Details

MCP concepts:
- Hosts: LLM servers
- Clients: Applications using LLM
- Servers: Tool providers
- Tools: call and list operations
- JSON-RPC 2.0 protocol

## Dependencies

- TICKET-004 (architecture)

## Related Files

- `docs/MCP_ARCHITECTURE.md` (to be created)
- `ARCHITECTURE.md`

## Notes

Foundation for all MCP tool work. Should be done early.
