Knowledge & Memory
272 MCP servers and agent skills in the Knowledge & Memory category, ranked by quality score — 272 results.
teflon07/memkeeper
Local-first memory for AI agents: a single self-contained Rust binary over one SQLite file. Hybrid BM25/FTS + on-device ONNX embeddings + cross-encoder rerank; abstains instead of returning a confident wrong memory. No server, no API key, zero marginal cost. `memkeeper mcp`
michielinksee/linksee-memory
Local-first cross-agent memory with a 6-layer structure, Ebbinghaus-style forgetting curve, and drift detection that catches when code diverges from past decisions. One SQLite file shared across Claude Code, Cursor, Codex, and Gemini — no account or API key. `npx linksee-memory`
michael-denyer/memory-mcp
Two-tier memory with hot cache (instant injection) and cold semantic search. Auto-promotes frequently-used patterns, extracts knowledge from Claude outputs, and organizes via knowledge graph relationships.
CheMiguel23/MemoryMesh
Enhanced graph-based memory with a focus on AI role-play and story generation
elvismdev/mem0-mcp-selfhosted
Self-hosted mem0 MCP server for Claude Code with Qdrant vector search, Neo4j knowledge graph, and Ollama embeddings. Zero-config OAT auth, split-model graph routing, session hooks for automatic cross-session memory, and 11 tools. Supports both Anthropic and fully local Ollama setups.

Pull Deep Memory from across your Claude Code Sessions — when you need it.
hubinoretros/deep-thinker
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`
leonardsellem/hypermnesic
Git-first memory for AI agents: Markdown files are truth, the index is disposable, and writes are reviewable commits. Ships 7 MCP tools (hybrid search, read_note, build_context, resolve, think, list_folders, and a scope-gated commit_note write) over a Streamable HTTP endpoint, plus a CLI and a read-only Obsidian companion.
tribal-memory/tribal
Self-hosted semantic memory server, served over MCP, for an engineering team's tribal knowledge: the tacit decisions and hard-won reasoning behind the code, captured once and kept queryable for the team and the agents they work with. Postgres-backed (pgvector).
jmpdsevilla/BovedIA
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`
jessedu29260-netizen/booboo
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`
robotel-limited/robo-cortex
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

atakanelik34/Bilinc
Hosted agent memory that keeps an audit trail. Three tools — `commit_mem`, `recall`, `status` — where each write carries provenance (which run, tool, or operator produced it), contradictions with prior state surface as inspectable changes rather than silent overwrites, and a bad run is recovered from a snapshot instead of repaired by hand. `pip install -U bilinc`
decisionnode/DecisionNode
Record development decisions as structured JSON, embed as vectors via Gemini, and search semantically over MCP. Shared store across Claude Code, Cursor, Windsurf, and any MCP client. CLI + MCP server, local-only, free Gemini embedding tier.
