MCP Dotnet Diagnostics

Live .NET runtime diagnostics for AI assistants. Ask Claude to diagnose memory leaks, GC pressure, LOH fragmentation, and thread starvation in any running .NET process — no code changes required. Install: dotnet tool install -g mcp-dotnet-diagnostics

Waggle MCP

Abhigyan-Shekhar

Knowledge & Memory

Persistent graph memory for AI agents. Drop a conversation turn in via observeconversation() and facts are auto-extracted, stored as typed graph nodes with local semantic embeddings (no API key). Supports temporal queries ("what did we decide last week?"), conflict detection, and context priming. One-command setup with waggle-mcp init. SQLite locally, Neo4j in production.

Robrain

Knowledge & Memory

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.

Memora

agentic-mcp-tools

Knowledge & Memory

Persistent memory with knowledge graph visualization, semantic/hybrid search, cloud sync (S3/R2), and cross-session context management.

Zipmem MCP

Knowledge & Memory

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

Recallnest

Knowledge & Memory

Persistent memory MCP server for AI coding agents (Claude Code, Codex, Gemini CLI). Hybrid retrieval (vector + BM25), cross-encoder reranking, knowledge graph with PPR traversal, session checkpoint/resume, and multi-scope isolation. Local-first with LanceDB + SQLite, zero external dependencies.

Deterministic reasoning engine for AI agent context compression. Extracts structured facts with logical inference, proof chains, and truth maintenance. REST API, Python/TypeScript SDKs, and MCP server integration.

Memocall

Knowledge & Memory

Recall past Claude Code conversations from any project. Lists and searches your sessions, then loads one on demand as clean, compact Markdown — with outline, turn-range, and in-session search for large sessions. Read-only over local /.claude transcripts; collapses tool calls to stay under the context cap. npx -y memocall

Basic Memory

basicmachines-co

Knowledge & Memory

Persistent, local-first AI memory: a semantic knowledge graph of plain Markdown files that humans and LLMs both read and write. Works with any MCP client, with optional cloud sync and team workspaces.

Project Tessera

besslframework-stack

Knowledge & Memory

Local workspace memory for Claude Desktop. Indexes your documents (Markdown, CSV, session logs) into a vector store with hybrid search, cross-session memory, auto-learn, and knowledge graph visualization. Zero external dependencies — fastembed + LanceDB, no Ollama or Docker required. 15 MCP tools.

Cachly MCP

Knowledge & Memory

Persistent AI memory brain for Claude Code, Cursor, Copilot, Windsurf, Cline & Zed. sessionstart() briefs your AI on last session, lessons, and open tasks in one call. 84 tools — Team Brain, semantic BM25+ search, Team Telepathy, Ambient Git Learning, Memory Crystals, Analytics, and managed Valkey/Redis. npx @cachly-dev/init — free tier, no credit card.

Engram MCP

Knowledge & Memory

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.

Sessionmem

Knowledge & Memory

Local-first memory layer for AI coding assistants. Watches your coding sessions and injects a compact summary at the start of each new session. No cloud, no account, just a SQLite file on your machine. Works with Claude Code, Cursor, Cline, Windsurf, and any other MCP host.

Claude Find

Knowledge & Memory

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

Agentcairn

Knowledge & Memory
