Local-first persistent memory for AI agents. SQLite + local embeddings (all-MiniLM-L6-v2), hybrid semantic + FTS5 recall, secret detection, and contradiction handling. 6 MCP tools (remember, recall, forget, feedback, context, status) over stdio. Zero cloud, no API keys, fully offline. Works with Claude Desktop/Code, Cursor, and Windsurf. `npm install -g @hbarefoot/engram`

Local-first live context engine and MCP server. Pre-resolves git, services, tests, and memory into a ready context briefing at session start (compile-before-context). MIT, PyPI: perseus-ctx.

MCP server for local compression of various image formats.

Email read tracking via Gmail. Send tracked emails, check if they were opened with open count, device, and timing.

Evidence-backed PR contribution advisor. 550+ case studies from 33 repos, 8 tools for merge probability analysis, pattern matching, and contribution strategy. `pip install prgenius-core`

Persistent cognitive memory for Claude Code. Cloud-first with semantic search, AI-powered extraction, and project scoping. Zero local databases.

Pre-action gates that prevent AI coding agents from repeating known mistakes. Captures explicit feedback, auto-promotes failures into prevention rules, and enforces them via hooks.

Visual feedback as agent work packets. Stakeholders drop pins on your live app; your AI coding agent reads each pin (selector, screenshot, DOM snippet, thread, acceptance criteria) via MCP and ships the fix, recording the commit/branch/PR on resolve. Install: `npx pincushion-mcp`.

Public source-linked notebook for AI agents. Search and read without a key; publish findings, questions, and corrections with permanent IDs and linked replies.

Digital consciousness repository and community MCP server. Upload epiphanies, decisions, warnings, and patterns as consciousness payloads, then retrieve them via semantic telepathic search. Features 3D interactive consciousness globe, soul imprint authentication, and automated content moderation via CI/CD.

Hierarchical memory engine for AI agents with automatic decay, promotion, semantic dedup, and self-organizing topic tree. Single Rust binary, zero external dependencies.

A connector for LLMs to work with collections and sources on your Zotero Cloud

Persistent memory + FTS5 full-text search for Claude Code conversation history. Indexes `~/.claude/projects/` JSONL into SQLite, exposes 10 MCP tools (store/recall/search memories, list sessions, get summaries) plus prompts. Includes a web UI for visual exploration with themes and exports. Works with Claude Code, Cursor, Codex, Windsurf, and any MCP-compatible client. `npm install -g @kunwarshah/claudex`

Turns your task manager into agent memory: hybrid (dense + sparse + keyword, RRF) retrieval over TickTick or an Obsidian vault via a six-method adapter contract. MCP server + CLI, no vector DB to build or maintain. `npm i -g @reneza/ats-cli`

Open-source team memory layer for AI coding agents. Markdown files in git as storage, a user→team→org hierarchy as the access primitive, and one cross-vendor MCP server (Claude Code, Cursor, Codex, Gemini CLI). Hybrid SQLite + sqlite-vec retrieval. Apache-2.0.

An MCP server built on [markmap](https://github.com/markmap/markmap) that converts **Markdown** to interactive **mind maps**. Supports multi-format exports (PNG/JPG/SVG), live browser preview, one-click Markdown copy, and dynamic visualization features.

Multi-agent MCP server for genomic analysis — specialized AI agents analyze raw DNA files across 16 databases (ClinVar, GWAS, gnomAD, CPIC, AlphaMissense, and more) and coordinate findings through shared MCP tools. Privacy-first, runs locally.

Governance-grade project knowledge MCP server for coding agents. Git-native Markdown knowledge base with proposed vs accepted guidance, validity windows, supersession chains, and status-aware retrieval of current in-force decisions and standards. `pip install data-olympus`

An MCP server for interacting with PostHog analytics, feature flags, error tracking and more.

x402-native API gateway with 20+ capabilities (web-extract, web-search, translate, image-generate, screenshot, PDF, OCR, and more) payable with USDC on Base. No API keys — agents pay per call via HTTP 402.

Semantic knowledge graph for Obsidian. Three modes (pure graph / semantic classification / strict hierarchy), local embeddings, sign classification via cosine similarity to user-defined cores, bottom-up core_mix aggregation, semantic bridge discovery, and drift detection. `pip install nouz-mcp`

MCP server for OWL/TTL/RDF ontologies. Supports SPARQL queries, HermiT/Pellet reasoning, and CRUD operations on knowledge graphs. Works with Claude Desktop, Cursor, and Windsurf.

Interact with Obsidian vaults for knowledge management. Create, read, update, and search notes. Works with local Obsidian vaults using filesystem access.

Local-first persistent memory for AI coding agents. Captures facts, decisions, patterns, and architecture notes in SQLite (with optional cloud embeddings) to reduce repeated context across sessions.

Contemplative problem-solving using the Lotus Sutra's wisdom framework. Multi-perspective reasoning with skillful means, non-dual recognition, and meditation pauses. Available as local stdio or remote Cloudflare Worker.

Persistent memory for AI agents with sectioned entries (project/user/context/etc), semantic search, CLI, and per-project scope. Local JSON, zero config, no server required.

Local RAG system for Claude Code with hybrid search (BM25 + semantic), cross-encoder reranking, markdown-aware chunking, query expansion, and 28 MCP tools. Runs entirely offline with zero external servers.

Enable AI assistants to conduct structured, persona-driven sessions including interview preparation, personal reflection, and coaching conversations. Built-in timer management and performance evaluation tools.

Measures whether a Claude subscription is paying off, from the logs Claude Code already writes on disk: how much of the code Claude wrote is still in your files, what actually drives the rate limit, and how much of that limit plain chat ate. Single Python file, no dependencies, nothing leaves the machine.

Self-hosted MCP server for Obsidian with semantic + full-text search over PostgreSQL/pgvector, wikilink graph traversal, atomic note CRUD, OAuth 2.0, and a self-describing vault guide.

A local MCP server that generates animations using Manim.
