CCFDDL provides a read-only Model Context Protocol (MCP) server for AI clients to search conferences, check published deadlines and opening dates, and retrieve historical acceptance rates. It supports CCF/CORE/THCPL filters, pagination, and timezone conversion.
Connect using **Streamable HTTP** at `https://ccfddl.com/mcp`.
See the [MCP README](worker/mcp/README.md) for details.

Fields marked with asterisk (*) are required.
Deadline defaults are repository conventions: when an official source gives a
calendar date but no clock time, use `23:59:59` on that date. When the source does
not specify a timezone, use `AoE`. Document these defaults in comments where
appropriate; do not present them as times or zones stated by the source. A truly
unpublished date remains `TBD`. Resolve explicit conflicting dates from reliable
official evidence rather than choosing one arbitrarily.
