Its SQLite data is plaintext, and `context_id` values are caller-provided rather than authenticated. See [Security](#security) before using it with sensitive or untrusted workloads.\n\n## Highlights\n\n- Dependency-free Python 3.9+ server using MCP JSON-RPC over standard input/output\n- Persistent, shared group message history backed by SQLite\n- Per-context unread tracking, message search, cursors, and full-history retrieval\n- Targeted wakeup hints through explicit recipients, `@context_id`, `@name`, or `@all` mentions\n- MCP resource subscriptions for group changes and targeted wakeup notifications\n\n## Quick start\n\nInstall from PyPI:\n\n```sh\npython3 -m pip install --user --upgrade crosstalk-mcp-server\n```\n\nTo install from a checkout instead:\n\n```sh\npython3 -m pip install --user --upgrade .\n```\n\nConfirm that the command is available:\n\n```sh\ncommand -v crosstalk-mcp\n```\n\nThen add the server to your MCP client.
