Durable project-memory MCP: decisions, constraints, and pipelines across Claude sessions

Multi-agent shared brain MCP server enabling cross-session memory, self-improving skill loops, and inter-agent signaling across Claude, Codex, Gemini, Copilot, and VS Code CLI agents.

MCP server providing context usage estimation, conversation compaction, and durable semantic memory via local embeddings and SQLite.

Remote MCP server that exposes context-keeper's rationale store (decisions, pipelines, constraints) over Streamable HTTP, deployable on Cloudflare Workers and usable as a claude.ai custom connector.

Provides persistent context management for Claude AI coding assistants, allowing you to save and restore conversation context, create checkpoints, and organize information across sessions to prevent losing important work history and decisions during long coding sessions.

A local MCP server using SQLite to unify context and memory across multiple AI agents, enabling persistent decisions and preferences without re-explanation.

Local MCP server for Call of Cthulhu 7e, managing campaigns, character knowledge, and rule resolutions (d100, SAN, combat) with secure state isolation and keeper-controlled access.

Provides a 'library keeper' sub-agent that ingests PDF/EPUB books and answers questions grounded in them via local embedding search, with deterministic classification and knowledge gap logging.
