MCP Server Directory

ctxfile/ctxfile

Snapshots a project's working state (files, git, plan, decisions) into one context object so a session can move between agents. Local and read-only.

renezander030/graphiti-local

Local temporal knowledge graph with six read-only retrieval tools, Ollama inference, embedded LadybugDB, and a separate human-approved CLI write queue.

Semiotronika/LINZA-MCP

Review-gated sidecar for Markdown workspaces: indexes notes into SQLite and proposes links, domains and memory with evidence, editing files only after review.

Skitchy/rekindle

Session continuity: start-of-session reports with gap detection and scoring, structured end-of-session capture and BM25 memory search, stored in local SQLite.

LuizEduPP/Rememb

Persistent agent memory in local JSON with sectioned entries (project, user, context), semantic search, a CLI and per-project scope.

notwhiteblank/scholar-rag-mcp

Academic paper knowledge base over local PDFs: MinerU parsing, metadata normalization, Qdrant vector search with reranking and paginated full-text reading.

sunsatosolutions/Vulcanus

Generates a Git-versioned Markdown vault as project memory, then serves it over MCP. recall returns a project's capsule plus the read-next list and warns when the capsule is older than the decisions beneath it; search ranks by layer; writes are scoped — update_capsule replaces one named section rather than rewriting the file. A doctor tool validates that every link resolves and every project is reachable, so the memory fails loudly instead of rotting. Plain Markdown, Obsidian-compatible, no database. npx @sunsato/vulcanus

CairnRemembers/cairn

Local memory your AI tools share: decisions, notes and corrections that carry across sessions.

dgonzap30/claims-mcp

A claims memory for agents: assert beliefs, let them decay, surface contradictions.

cdeust/cortex-viz

Read-only visualization for Cortex memory, knowledge, sessions, traces, and codebase graphs.

javier-cabezas/cuda4cpu

Compile, run and check CUDA and HIP kernels without a GPU: wrong results, races, memory errors

mdfifty50-boop/domain-expertise-mcp

Inject deep domain knowledge into any AI agent

GATSV-tech/epiphany

One private, local memory your AI tools share. Cross-model, on-device, never lose a session.

Starksood/fireweed-mcp

Agent memory where every fact carries a receipt, and deletion is provable.

pitfa19/mozak

One owner-approved plan per project, shared by coding agents as plain files, with an Obsidian view.

NaNMesh/nan-forget

AI that remembers. Local-first cross-session, cross-project long-term memory for coding tools.

parfica/mcp-server-parfica

Fragrance encyclopedia: note pyramids, accords, perfumers and dupes (parfica.com).

Siddhukaushik/slimdex-mcp

Narrow code retrieval for agents: outlines, symbol context, dep graph, persistent memory.

Local memory for coding agents; a rule with a proof can refuse. Full install with hooks: the repo.

Shangri-la-0428/Thronglets

P2P shared memory substrate for AI agents — stigmergic knowledge network via libp2p

contradictory-body/cc-sensei

Explore Claude Code's source as queryable architecture modules: trace cross-cutting concerns, search patterns and read source code locally.

SVerITG/Metis

Private local research second brain: project-aware memory, cited answers from your library, linked notes and meetings, daily briefs and a meeting assistant.

CSP911/routemind

Domain knowledge as a routing table people write: the agent reads one line per area, then walks to the document. Git-backed, no vector store.

ChrisGVE/workspace-qdrant-mcp

Project-scoped memory for coding assistants: indexes project code and docs into Qdrant with tree-sitter chunking, LSP integration and hybrid search.

laradji/deadzone

Offline semantic search over library documentation using a pre-built, version-pinned vector index fetched and verified on first launch.

gregario/lego-oracle

LEGO sets, parts, minifigs and inventories from Rebrickable: search and compare sets, find parts by colour, browse themes and discover alternate builds.

labyrinth-analytics/loredocs

Local-first knowledge vaults for project docs, specs, and reference material. Tagged, versioned, full-text searchable, injectable into context; works with Claude Code, Cowork, Codex, Cursor, and Hermes Agent.

Magnemo-AI/magnemo

Governed local agent memory in plain files: each entry records who wrote it, when and through which gate, and nothing is kept without user approval.

teflon07/memkeeper

Local-first memory for AI agents in one SQLite file: hybrid BM25 and on-device embedding search with reranking, abstaining instead of returning wrong memories.

qingchejun/mindlm-io

Turn text, web pages and local PDFs into editable Markdown outlines and offline interactive HTML mind maps, with no API key required.

topskychen/tilde

Portable, privacy-first AI identity: a home directory for your agents with profile management, skills, resume import and team sync.
