"CCC" matching MCP servers:

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.

CTX is a tool made to solve a big problem when chatting with LLMs like ChatGPT or Claude: giving them enough context about your project.

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.

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

MCP server that exposes 45 tools for Zotero reference management, enabling AI agents to read/write items, search, extract PDF text, and manage workspaces via the Zotero CLI.

Provides a web_search MCP tool for cc-switch, backed by a self-hosted SearXNG instance, enabling AI assistants like Claude Code to perform web searches without a premium API key.

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.

Compiles and routes context from trust-domain sources (session, workdir, knowledge, shared) into unified, trust-tagged context envelopes for agents, without storing any data itself.
