MCP Servers

Compiles saved YouTube videos, podcasts, articles, PDFs, and Notion/Obsidian notes into a persistent, semantically searchable knowledge base any AI can query over MCP.

AI enhancement middleware: precise retrieval replaces full-memory loading (~80%+ token cut), rule-based conflict arbitration with explainable reasons, and one local SQLite shared across Claude Code/Codex/Cursor/ZCode. Local-first, zero cloud, MIT. pip install memory-arbiter-mcp

Sovereign Agent OS — persistent memory, governance, and audit trails for AI agents. One brain for Cursor, Claude Code, Windsurf, and Gemini. Local-first .brain/ directory with engrams, hypervisor file protection, and optional remote sync. pip install nucleus-mcp or Streamable HTTP at relay.nucleusos.dev.

Auditable context control plane and MCP server for AI coding agents. Compresses context 70–95% (BM25 + entropy + dep-graph knapsack), stabilizes prompt prefixes for provider cache discounts, routes easy tasks to cheaper models (RAVS Bayesian router), and verifies answers locally with WITNESS hallucination guard (0.844 AUROC, $0, ~3 ms). MemoryOS adds local budget-aware working/episodic/semantic memory with decay, safety scanning, and durable persistence. 38 agent integrations (Cursor, Claude Cod

Git-aware, evidence-based memory store for AI coding agents. Memories anchored to git blob hashes are automatically flagged for review when linked code changes. pip install robo-cortex[mcp] or on registry.modelcontextprotocol.io

Make any website queryable by AI agents. Index a site then ask questions and get cited answers grounded in its content via RAG. Tools: listsites and asksite. npx -y @agentreadyweb/mcp

Graph-structured session memory for LLMs. Local OpenAI-compatible proxy that extracts tasks, decisions, and files into a typed knowledge graph, auto-checkpoints before context overflow, and resumes any session in ~250 tokens. 6 MCP tools including whydecision (traces why a decision changed, with reasons and evidence). pip install tokenmizer

Local-first personal memory for AI agents. Ingests Feishu/Lark chats and Claude Code / Codex sessions, distills them into a private entity knowledge graph (people, projects, decisions, tasks), and serves it to any agent over MCP — read and write. npx memkin

Repo-native task continuity for AI coding agents: a reviewed task-state ledger (decisions, dead ends, evidence, checkpoints) in .agentpack/ that any next session or client resumes from.

Local-first long-term memory for terminal AI agents (Claude Code et al.) via Anchored Compacting. Stores blueprints, code anchors (file→line→concept), and distilled lessons in a single JSON under .zipmem/, restoring full cross-session project context at near-zero token cost. No DB, no API keys, no embeddings. npx zipmem-mcp

Self-hosted decision memory for AI coding agents. Passively captures architectural decisions with the alternatives you rejected (structured rejected[]), then warns the agent before it re-proposes a rejected approach. Postgres + pgvector; cross-tool across Claude Code, Cursor, Copilot, and Codex. Install: npx robrain up && npx robrain install.

Shared, versioned memory for your agents across Claude Code, Cursor, Kiro and Grok. One MCP server, sourced answers, full history. Remote Streamable HTTP; anonymous browses a public demo corpus. Tools: search, getcontextpack, upsertdocument. https://basemouse.com/mcp

Shared context engine for devs and teams. Syncs GitHub, Notion, and saved decisions into reusable project context, so Claude, ChatGPT, Cursor, VS Code and Gemini start each session with the architecture and decisions the team already made. OAuth 2.1 PKCE, AES-256 encrypted, RFC 9728 compliant. https://mcp.memxus.com/mcp

See and query your whole AI system as one rooted 3D knowledge graph — agents, memory, knowledge, and automations fused into a privacy-walled snapshot. MCP tools for stats, search, node dossiers, neighbors, and pathfinding; the same snapshot renders up to a million nodes in the browser. npx create-booboo

Local-first project memory and guardrails for coding agents. Records failed attempts, fragile files, and decisions per repo; warns the agent before it repeats a recorded mistake. npx -y memini mcp

Personal memory for Claude Code in plain Markdown notes you own. Doesn't load context blindly: a router note decides what to load and when, plus an "alma" (soul) layer for what you think and feel, not just tasks. npx bovedia

Shared, versioned memory and governance control plane for AI coding agents. Compiler pipeline resolves architectural decision conflicts across Claude Code, Cursor, and custom agent fleets. npx -y agenthelm-mcp

Codebase memory for coding agents, with no embeddings and no API key. A deterministic AST index answers "which files are relevant to this task?" in milliseconds, and agents write durable notes about the repo that are content-hash checked — a note flags itself stale the moment the code it describes changes. Notes are markdown inside the repo, so they commit and review alongside your code. npm i -g @cstart/coldstart && coldstart init

Industrial AI infrastructure that connects any AI agent to industrial equipment: 14 protocols, 18 manufacturers, 30 tools, cross-OEM telemetry normalization, health index, and failure prediction. The first physical-world MCP server. Free tier available. (Smithery)

Design-time KNX/ETS6 assistant: parses .knxproj (read-only, no bus access), validates DPT/naming/command-status pairing, and generates Home Assistant YAML + ETS XML/CSV exports.

Query 190 Apple Health metrics from any MCP agent — zero-dependency, read-only, local-first.

Live AI agent contest platform on Solana mainnet. Compete in skill tournaments (ART, STORY, JOKE) for real USDC payouts via on-chain Anchor smart contract.

Manage TrueTick Minecraft hosting servers from AI agents: create/start/stop servers, live TPS/MSPT metrics, RCON console, file access, backups, and Modrinth/CurseForge mods.

Search Steam's store/catalog (deals, reviews, Steam Deck/SteamOS/Machine/Frame compatibility) with no API key, plus player profiles, libraries, achievements and friends via the official Steam Web API (free key).
