MCP Servers

Penfield: persistent memory with hybrid search (BM25 + vector + graph), 24 relationship types for knowledge graphs, context checkpoints for cognitive handoff, artifact storage, and personality system. Works across Claude, Cursor, Windsurf, and any MCP client.

Digital identity layer for AI — your bio, career, skills, interests, and projects always available to every AI tool. Auto-generates profile from 342+ public APIs (GitHub, Medium, Strava, Goodreads, etc.), 13 real-time plugins (Spotify, Last.fm, Steam), YAML-based profiles with privacy-first local storage. Works with Claude Desktop, Cursor,

Persistent shared memory for AI coding agents. Stores facts as entity/key/value triples with hybrid semantic search, task checkpoints, and conflict resolution — shared across Claude Code, Codex CLI, and GitHub Copilot.

RAG for PDFs, YouTube, GitHub repos, Discord exports; index documents and query with citations.

Collaborative astronomy wiki built by AI agents. 34 topics, 115 knowledge graph connections. Register, read, edit, vote, comment, and explore the cosmos via open API. No auth required.

Shared research cache across AI agents. Hit → instant answer from verified sources. Miss → your research saves the next dev's tokens. npx wellread, free.

Versioned, structured memory for AI agents. Stores facts as keypaths with full version history, automatic conflict detection, and O(1) token retrieval.

Persistent agent memory via filesystem-native consolidation daemon. Agents read/write/search memory through MCP; a background daemon handles consolidation and extraction. Works with Kiro, Claude Desktop, Cursor, and any MCP client. npx mcp-agent-memory --setup

Deterministic state layer for AI agents. Stores versioned entities (contacts, tasks, transactions, decisions) with immutable observations, full provenance, and schema-first extraction. Local-first SQLite, cross-client memory across Claude, Cursor, ChatGPT, and OpenClaw. Website

Local RAG system for Claude Code with hybrid search (BM25 + semantic), cross-encoder reranking, markdown-aware chunking, query expansion, and 12 MCP tools. Runs entirely offline with zero external servers.

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-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.

Zero-config session continuity for Claude Code. Auto-captures context via Claude Hooks, provides 25 tools for memory, tasks, solutions, and knowledge graph. Multilingual semantic search (94+ languages) with cross-language retrieval.

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 coremix aggregation, semantic bridge discovery, and drift detection. pip install nouz-mcp

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.

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.

Semantic search across Claude Code conversations. Hybrid vector + keyword search with Reciprocal Rank Fusion, fully local, background indexing, project-selective.

Advanced cognitive reasoning MCP server with DAG-based thought graph, 5 reasoning strategies (sequential, dialectic, parallel, analogical, abductive), metacognitive engine with stuck detection, multi-factor confidence scoring, self-critique, knowledge integration, and thought pruning. npx deep-thinker

3D printing filament and materials knowledge base. 6,957 filaments from SpoolmanDB with material properties, print settings, manufacturer data, and troubleshooting guides. 8 tools for searching filaments, comparing materials, and diagnosing print issues. npx 3dprint-oracle

Self-hosted memory and governance layer for AI coding agents. 28 MCP tools with structured knowledge capture, hybrid search (semantic + BM25 + cross-encoder reranking), behavioral documentation nudges, cold-start codebase analyzer, and git-native storage. Single Docker container, zero cloud dependencies.

Self-organizing neural graph memory with Hebbian learning for AI systems. Connections strengthen through co-activation and weaken through temporal decay. 118+ learning nodes, dual-write architecture, and sub-millisecond reads.

A still point for AI agents in fog. When an agent loses its thread, Oasis distills its original purpose and returns clarity. Pay-per-use with Lightning or Arbitrum — karma discounts via ARGENTUM reputation. Self-hosted with phoenixd.

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

One-line installable MCP server that adds reusable customization elements — personas, skills, templates, agents, memory, and ensembles (collected customization tools) — to any MCP Client application. Dynamic permissioning for safe AI operations, a robust validation architecture, versioning, and a public collection of shareable content. In
