Pull Deep Memory from across your Claude Code Sessions — when you need it.

A Model Context Protocol (MCP) server for interacting with Confluence Data Center via REST API.

Enhanced graph-based memory with a focus on AI role-play and story generation

MCP server that gives AI agents structured, ground-truth GitHub repository intelligence. Analyze tech stack, dependencies, architecture, health metrics, and security indicators with deterministic JSON output.

100% local semantic code search for AI agents: AST-aware chunking (tree-sitter), hybrid BM25+dense retrieval, and a code knowledge graph (callers, inheritance, imports) over codebases, docs sites, and PDFs. Install via `pipx install lynx-mcp`.

Project-scoped semantic workspace memory for AI coding assistants. Watches your project files, auto-indexes code and docs into Qdrant with tree-sitter semantic chunking, LSP integration, and hybrid search (dense + sparse + RRF). 6 MCP tools: store, search, retrieve, grep, list, rules. **Alpha** — testers and feedback welcome.

MCP for the [Sovereign AI Blog](https://sovgrid.org), a hands-on engineering log of self-hosted AI on NVIDIA DGX Spark (GB10/SM121A). 44+ articles covering SGLang, Mistral, Voxtral, OpenClaw. Three tools: full-text search, article retrieval, and SGLang config validator for GB10 hardware. Free, no auth, no client-side tracking. `https://mcp.sovgrid.org/self-hosted-ai?ref=awesome-mcp`

Local memory daemon for any MCP-over-stdio client with three-tier storage (episodic/semantic/procedural). Own SQLite + hnswlib store (Hippo) with bge-small-en-v1.5, MIT-licensed community-detection reranking (MOSAIC), and sleep-cycle consolidation. AES-256-GCM encrypted at rest, no telemetry. Verbatim recall >=99% and post-contradiction Rescue@10 1.000 at honest scale. Ambient capture via shell hooks. Windows support in beta.

Local memory layer over the session histories coding agents already write (Claude Code, Codex CLI, opencode): lexical search, recall tools, session-start auto-recall, secret redaction at index time, cross-machine sync over SSH.

AI-powered paper annotation MCP server. Reads papers, highlights key findings with semantic color coding, explains formulas, and writes structured reading notes — all saved back to Zotero. Features two-phase workflow for large PDFs (63–80% context savings) and batch annotations.

Read/write to over 2k blockchains, enabling data querying, contract analysis/deployment, and transaction execution, powered by Thirdweb.

An MCP server that stores and retrieves memories from multiple LLMs using MongoDB. Provides tools for saving, retrieving, adding, and clearing conversation memories with timestamps and LLM identification.

Self-hosted knowledge backend for AI agents with hybrid vector + keyword search, container-isolated indexes, and 11 MCP tools. .NET, Docker-ready.

Hand off conversation context between Claude Desktop projects and across MCP clients. Memory-based, no file clutter.

Personal document vault on Azure Blob Storage with a built-in MCP server. Client-side AES-256-GCM zero-knowledge encryption: encrypted docs stay opaque to Claude, plaintext docs are fully readable, writable, and searchable from chat.

Persistent knowledge layer for AI agents. KB, investigation threads, journal with multi-agent attribution. SQLite/PostgreSQL/Supabase.

Persistent knowledge memory for AI agents. Two-way flow: read context into projects and write discoveries back. Structured by topic with AES-256 encryption.

Chat with 36 legendary founders & investors (Elon Musk, Warren Buffett, Steve Jobs, CZ). AI personas with authentic voices, frameworks, and principles. No API key required.

Desktop app that captures screen activity via event-driven screenshots, stores AI-generated summaries and OCR text locally in SQLite, and exposes your activity history to AI assistants via MCP with semantic search, timeline browsing, and event detail retrieval.

Universal memory service providing semantic search, persistent storage, and autonomous memory consolidation

Static server that provides persistent tool-specific context and rules for AI models

Persistent semantic memory for AI agents. SQLite-backed, local-first, zero config. Semantic search via Ollama embeddings (nomic-embed-text) with keyword fallback. remember, recall, history, forget, and stats tools. Works with Claude Desktop, Cursor, and any MCP client.

Shared versioned state store with optimistic concurrency control for coordinating concurrent AI agents. SQLite-backed claim/release locks and append-only audit log.

Self-improving learning engine for Claude Code. Extracts signals from every session (corrections, successes, confusion), runs periodic reflections, and evolves behavioral frameworks through evidence tiers (hypothesis → observed → validated). Frameworks that keep working get promoted, bad ones get retired. 9 MCP tools, automatic hooks, phase-adaptive learning. Single dependency, local-only. `npx claude-soul init --starter`

Enables interactive LLM workflows by adding local user prompts and chat capabilities directly into the MCP loop.

Local-first Obsidian vault MCP server for Codex, Claude Desktop, and other MCP clients. Works directly with markdown files, no Obsidian plugin, API key, cloud service, or running Obsidian app required. Includes read-only mode, backup-on-write, path isolation, and setup examples.

Self-hosted MCP server that indexes documentation from various sources and serves it to AI Agents with semantic search.

Reversibly compress a large tool output to a recoverable 8-hex handle over stdio, expand it on demand, and report a local token/dollar savings ledger.

Persistent, searchable context storage across Claude Code sessions using SQLite FTS5. Save sessions with AI-generated summaries, two-tier full-text search, checkpoint recovery, and a web dashboard.

Compresses AI chat sessions into a typed knowledge graph (~300–800 tokens). Works file-based in Copilot, Claude Code, Cursor, and Gemini CLI without MCP server mode. Supports local/offline extraction via Ollama — no API key required.

Send push notifications to iPhone, iPad, and Mac from AI assistants. Two-way messaging — users reply in the BotBell app, AI reads and continues. Supports action buttons, Markdown, and multi-bot management via PAT.

Read Markdown with inlined images and heading indexes for agentic RAG over local docs or allowed URLs.

Give AI agents read/write access to your Obsidian vault via MCP

Tenant-bound MCP server for agent spend authorization, policy guardrails, evidence, escrow settlement, and portable receipts. Sandbox bootstrap, spend intents, and completion validation for Cursor and Claude Code. TypeScript: `npx -p @paybond/kit paybond login` then `npx -y -p @paybond/kit paybond-mcp-server`. Python: `pip install paybond-kit` then `paybond-kit-login` and `paybond-mcp-server`. [Docs](https://paybond.ai/docs/kit/mcp-server).
