Extract agent-core as shared package with agentic loop,
tool definitions, and MCP integration. Compass tools
wrapped as MCP server using low-level Server API. Client
manager connects multiple MCP servers (in-memory, stdio,
HTTP) with unified tool routing. External MCP server
configs stored in DB with CRUD actions. Both Workers and
Bun runtimes use the new MCP client manager.
Replace Vercel AI SDK with Anthropic Claude Agent SDK.
Add standalone agent server (packages/agent-server/)
with MCP tools, JWT auth, and SSE streaming. Introduce
bridge API routes (src/app/api/compass/) and custom
SSE hooks (use-agent, use-compass-chat) replacing
useChat. Remove provider.ts, tools.ts, system-prompt.ts,
github-tools.ts, usage.ts, and old agent route.
