"Top 100 MCP Servers Ranked by Weekly Downloads" matching MCP servers:

An MCP server that generates security weekly reports and manages a terminology glossary for the Taiwanese cybersecurity community.

Provides MCP tools to search, compare, and get recommendations for open-source projects from a structured knowledge graph of GitHub data.

Local-first shared memory that several AI apps can use at once, with every change recording which app, model and machine made it.

Agent memory for facts that change. When a user corrects something, Recall replaces the old fact, tells the agent what it replaced, and keeps the old value in a history. Ask what was believed on any date, see every change to a fact, or diff two dates. Runs locally on polign_db, Postgres with pgvector, MongoDB, or Qdrant. Apache 2.0.

Scope by Ouroboros Apps (https://ouroborosapps.com). Freelance scope of work: approved scope, rates, deadlines, and change orders, so an assistant cannot promise work or discounts that were not approved. Connect by pasting https://scope-continuity2.vercel.app/mcp into Claude, Cursor, Grok, or ChatGPT developer mode (OAuth). Docs: https://ouroborosapps.com/docs/scope

Continuity by Ouroboros Apps (https://ouroborosapps.com). Story continuity for fiction writers: a series bible and novel memory that keeps characters, places, timelines, and plot facts consistent across chats. Connect by pasting https://continuitywriter.com/mcp into Claude, Cursor, Grok, or ChatGPT (OAuth). Docs: https://ouroborosapps.com/docs/continuity

Milestone by Ouroboros Apps (https://ouroborosapps.com). Freelance project milestones: approved milestones, deliverables, and acceptance criteria; a milestone is only done when the saved criteria are met. Connect by pasting https://milestone-continuity2.vercel.app/mcp into Claude, Cursor, Grok, or ChatGPT developer mode (OAuth). Docs: https://ouroborosapps.com/docs/milestone

Claim by Ouroboros Apps (https://ouroborosapps.com). Brand claims and marketing copy compliance: approved claims, offers, proof, brand voice, and banned phrases, with a check that rejects copy inventing a guarantee or discount.

Design contract layer for AI agents. Scans Figma, code, Storybook, and token files, reconciles conflicts, and serves a single machine-readable source of truth so every agent gets the same authoritative design rules before it builds. Local-first.

A modular MCP server suite that provides core tools, long-term memory, knowledge RAG, skills registry, and external integrations for AI agents.

Integrates with Get Notes API to search and retrieve knowledge from configured knowledge bases with AI-powered synthesis and raw recall capabilities.

Enables AI assistants to maintain a persistent, local memory using SQLite with ranked full-text search, German morphological matching, and two-axis filing, all without external services.

Provides AI agents with persistent long-term memory over MCP, extracting durable facts from conversations, storing them as plain files, and injecting ranked memories into later sessions via recall and search tools.

MCP server that gives AI coding agents on-demand access to private project docs via BM25 ranked search. One setup for Claude Code, Cursor, Codex, Gemini CLI, and more. Docs stay private, never in public repos.

Analytical memory for AI agents: a real Postgres your agent connects to over MCP and queries in plain English — GROUP BY, JOIN, aggregate over what it remembered, not just top-k vector recall.

Filesystem first MCP server for Obsidian vaults with an LLM-Wiki layer on top.

A local MCP server that lets coding agents persist decisions, conventions and gotchas across sessions and recall them with ranked search. Each memory is anchored to the files it describes, so recall flags it as stale when that code changes, and secrets are redacted before anything is stored.

Secure MCP server that bridges AI clients like Claude Desktop to Obsidian vaults, enabling read/write operations with OWASP Top 10 security controls and audit logging.

A local-first, privacy-first MCP server that passively indexes personal digital activity (screenshots, clipboard, notes, downloads, links) into a local database, enabling LLMs like Claude to access your context without cloud storage.

Local deterministic BM25 memory for AI agents — offline-first, no API key, SHA-256 content-addressed shards, stdio MCP transport. Same query always returns the same ranked result.

engRAM provides encrypted, offline, RAM-resident memory for AI agents via MCP, enabling fast hybrid search, deterministic importance-based recall, and secure vault management with tools like memory_search, memory_store, and memory_forget.

Lets an AI assistant search, read, and write notes and sources in your self-hosted Open Notebook, with approval-gated writes and no data sent anywhere else. It bundles tools, prompts, and skills for meeting notes, decision records, weekly reviews, and source-cited research.

AI workflow orchestration platform with 100+ integrations, knowledge graph, and unified credits. Build, manage, and execute workflows from Claude Code, Cursor, or any MCP client.

Provides OpenCode with adaptive long-term memory by storing preferences, lessons, and usage history locally in SQLite, enabling AI to remember and adapt to users through context-based learning.

Enables agents to store, search, and manage a personal penetration testing knowledge base via MCP, using BM25-ranked retrieval with Chinese tokenization, plus draft approval, deduplication, and sensitive-data redaction workflows.

Persistent memory for Claude Code. Automatically indexes every conversation and provides production-grade hybrid search (BM25 + vectors + reranker) via MCP tools. 100% local, zero config, zero API keys, zero invoice.

An MCP server that provides semantic memory on top of Qdrant vector search, with tools to store and retrieve information using embeddings.

Gives any AI tool persistent, searchable memory across sessions using hybrid semantic and keyword search, running 100% locally with no API keys or cloud dependencies.

Turns any MCP-capable AI assistant into a goal coach backed by a local plain-text vault. Enables creating goals with if-then plans, logging check-ins and habit outcomes, searching notes, and generating weekly reviews, with all reads and writes confined to the vault on your machine.

Serverless, 100% decentralized P2P storage engine and shared memory mesh for autonomous AI agents via Hyperswarm DHT and Hypercore v10. Zero cloud costs, sub-50ms sync, and OWASP 2026 agentic security hardening.
