Add an MCP server exposing calendar and saint-search tools - #158
Merged
Conversation
Adds mcp_svc, a new Django app hosting an MCP (Model Context Protocol) server via the official mcp SDK, mounted alongside Django's own ASGI app in orthocal/asgi.py. Exposes two tools over Streamable HTTP at /mcp: get_day (feasts, fasting, readings, and saints for a date, with tradition/calendar/translation selection, reusing calendarium.api's DaySchema) and search_saints (find a saint's fixed commemoration date(s) by name). Also adds: - An "AI Assistant" page documenting how to connect an MCP client. - .well-known/mcp/server-cards.json and llms.txt discovery metadata for AI agents/crawlers (the former follows a still-draft MCP spec proposal, SEP-2127, as of 2026-08). django-mcp-server was evaluated and rejected: it's incompatible with the mcp SDK's 2.0 rewrite (FastMCP renamed/relocated), with no fix in progress. Hand-rolled against the current SDK instead -- the actual composition needed turned out to be a small ASGI dispatcher, not the large lift originally assumed.

Changes the MCP server's get_day tool default translation from kjv to lxx2012-web (kjv remains available on request). Also expands the AI Assistant page's connection instructions to cover Claude Desktop and ChatGPT (both support custom remote MCP connectors for regular consumer accounts) alongside the existing Claude Code example.

Summary
mcp_svc, a new Django app hosting an MCP (Model Context Protocol) server via the officialmcpSDK, mounted alongside Django's own ASGI app inorthocal/asgi.py./mcp:get_day— feasts, fasting, readings, and saints for a date, with tradition/calendar/translation selection. Reusescalendarium.api'sDaySchemadirectly rather than re-deriving the response shape.search_saints— find a saint's fixed commemoration date(s) by name./ai-assistant/) documenting how to connect an MCP client, linked in the nav..well-known/mcp/server-cards.jsonandllms.txtdiscovery metadata for AI agents/crawlers. The server-card follows a still-draft MCP spec proposal (SEP-2127) as of 2026-08 — field names/path may shift before it's finalized, but it's a cheap, low-risk static endpoint to have in place early.Notable decision
django-mcp-serverwas evaluated and rejected: it's incompatible with themcpSDK's 2.0 rewrite (FastMCPrenamed/relocated toMCPServer), with no fix in progress upstream (confirmed by checking its GitHub activity). Hand-rolled against the current SDK instead — the actual ASGI composition needed turned out to be a small dispatcher (~10 lines), not the large lift originally assumed when scoping this.Test plan
