Move MCP templates to the v2 SDKs - #21
Conversation
keycardai-mcp 2.0.0 (PyPI) and @keycardai/mcp 2.0.0 (npm) shipped, so the five templates that were pinned to the v1 line move over. Python (mcp-server-python-mcp, mcp-brokered-credentials-python): keycardai-mcp>=2,<3, drop the interim mcp<2.0 pins. Source: mcp.server.fastmcp -> mcp.server.mcpserver, and streamable_http_path moved from the MCPServer constructor to streamable_http_app(). TypeScript (mcp-server-typescript-express, mcp-brokered-credentials-typescript, autonomous-agent-snowflake-wif): @keycardai/mcp ^2.0.0 and the v2 package split, server code on @modelcontextprotocol/server + /node, client code on @modelcontextprotocol/client (Client, StreamableHTTPClientTransport and the PRM discovery helpers all export from its root). server.tool() is gone in v2, replaced with registerTool(name, config, cb). Handler context carries auth at ctx.http.authInfo instead of ctx.authInfo. zod moves to ^4 (v2 types its schema overloads against zod 4, and z.record now requires an explicit key type). Verified locally: both Python templates resolve keycardai-mcp 2.0.0 with mcp 2.0.0 and import clean; all three TypeScript templates typecheck and build. The repo CI verifies each against a live ephemeral zone. Go templates are untouched: no Go v2 exists and they moved to go-sdk v1.7.0 in #19. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Final PR of the MCP v2 cutover.
keycardai-mcp2.0.0 and@keycardai/mcp2.0.0 are published, so the five templates on the v1 line move over. Go templates are untouched (no Go v2; they got v1.7.0 in #19).Python — 2 templates

CI verifies every changed template against a real ephemeral zone.
