"CCC" matching MCP servers:

Lossless, categorized long-term memory for Claude Code (and any MCP client), backed by Qdrant, capturing compaction summaries across generations.

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.

Local MCP server that bridges Beale research workspaces to Claude Code, providing typed memory, workspace search, revisioned runbooks, and research profile context via a stdio plugin.

Persistent, structured memory for AI coding agents via a git-like filesystem with branch/commit/merge tools, enabling agents to maintain context across sessions.

Provides local-first, cross-session memory for Claude Code, enabling semantic search across past sessions to retrieve procedures, decisions, or answers without exposing secrets.

Enables cross-session memory, weighting, and factory/PR/artifact linking for CIC agents, aggregating multiple sessions to identify promotion candidates.

An MCP server and background daemon that captures Discord and Telegram conversations locally to provide persistent memory for Claude Code sessions. It enables hybrid search and automatic context injection of chat history to maintain continuity across development sessions.

Provides Claude with long-term memory by indexing conversation history, enabling semantic search, decision tracking, and cross-project search.

CCR gives MCP-capable AI agents persistent project memory, strategy playbooks, and a sandboxed Python REPL.

A typed, append-only event log and resume system for Claude Code, enabling agents to record schema-validated events like plans, decisions, questions, and human feedback via an MCP server for consistent session resumption.

Stores and serves a single conversation/session context for CIC agents, providing event ingestion, timeline projection, and search capabilities within a session scope.

agentcairn is a local-first memory MCP server: your agent's memories live as Markdown in an Obsidian vault you own — the source of truth — with a rebuildable DuckDB index providing fast hybrid BM25 + vector + graph recall. It exposes tools to capture, recall, and manage those memories (non-lossy, with secret redaction) and works the same across Claude Code, Codex, Cursor, and any MCP host.

MCP Memory Server for Claude Code that provides persistent context across sessions using semantic search (RAG).

Enables semantic search over the CCI Black Book, a scanned grow manual, retrieving both text and visual content with cited evidence packs for AI assistants.

Provides AI-assisted judgment calibration by surfacing counterexamples, boundaries, and blind spots from a local knowledge base before acting on model answers.

A personal MCP server for managing a folder of markdown notes. It provides tools to search and list notes, resources to access individual notes, and a prompt for weekly summaries.
