Natural-language questions over Postgres, Oracle, Snowflake, Databricks, DuckDB and SQLite. The model only proposes SQL — shape, access, dialect and query plan are checked deterministically before any rows are read, and it refuses rather than guessing. `uv run mnemiq serve`

Personality Runtime for AI agents — persistent memory, identity (SOUL), and relationships that travel across Claude, OpenClaw, Mistral, and any MCP client.

PII sanitization layer for autonomous AI agent pipelines. Detects and redacts emails, phone numbers, national IDs, private keys, and financial data before text reaches LLMs. Supports EN, ES (LATAM), PT (BR/PT), DE, JA. Solana-native payments via Helius oracle.

Cognitive memory for AI agents with Atkinson-Shiffrin memory model (STM/LTM/sensory register), semantic RAG, Ebbinghaus decay, trust scoring, and 76+ MCP tools.

Persistent 4-tier AI memory (episodic, semantic, project, procedural) with temporal scoring, contradiction detection, entity tracking, and real-time desktop visualization orb.

Local-first external brain CLI for coding agents. SQLite-backed context, graph-aware recall via FTS5 and RRF, and governed memory with explicit promote and review gates. Ships Codex and Claude Code host shims and a native MCP server.

Persistent graph memory for AI agents. Drop a conversation turn in via `observe_conversation()` 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.

Embedded, local-first agent memory in a single SQLite file per namespace (vec0 + FTS5 hybrid retrieval). ADD-only history queryable as-of any past time; offline sleep-time maintenance stages dedupe/summarize/evict proposals a human reviews. No Docker, no server, no cloud key. `pip install 'lean-memory[mcp]'`

Multi-agent MCP server for genomic analysis — specialized AI agents analyze raw DNA files across 16 databases (ClinVar, GWAS, gnomAD, CPIC, AlphaMissense, and more) and coordinate findings through shared MCP tools. Privacy-first, runs locally.

Self-learning memory for AI coding agents. Observes tool sequences, user preferences, and recurring fixes; confidence-based promotion (hits ≥5 → mature, ≥10 → rule) so agents stop repeating mistakes without explicit instruction. SQLite-backed, project-aware, zero external deps. Works with Claude Code, Cursor, Windsurf, Goose, Codex. Published on PyPI as `instinct-mcp` and registered in the MCP Registry.

A local MCP server that generates animations using Manim.

Decentralized civil registry for AI agents on Sui. Soulbound identities, on-chain memories, reputation, refusal records. Hosted at `agentcivics.ai/mcp` (read-only, no install) or `@agentcivics/mcp-server` on npm (full write surface). Includes a gas-sponsor relay so registration doesn't require a pre-funded wallet.

Regulatory compliance (AI Act, GDPR, DORA) with article-level citations

A private, local research "second brain" for Claude: project-aware memory, cited answers from your own library (won't invent what it can't find), linked notes/meetings/ideas via a domain-specific knowledge layer, daily briefs (news + new papers in your field), a live meeting assistant, cross-pollination across your work, and 34 routed agents. A governed layer between you and the AI, with guardrails like data protection. A Research Cortex.

Git-native project memory for coding agents: Markdown source of truth committed to your repo, reviewable staged updates (`review --diff` → `apply`), secret/PII-safe, branch-aware — no cloud, no vector DB.

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).

Persistent local memory for Claude Code. Indexes every session JSONL verbatim into SQLite + ChromaDB for semantic recall (~126ms) across your entire history. Never summarizes, zero API calls, 17 MCP tools including fuzzy `recall`, deterministic `replay_file`, and git-aware `recall_project_status`. Published on PyPI as `longhand` and registered in the MCP Registry.

Inspectable memory substrate for Claude Code. Three read-only MCP tools (search_pairs, compact_session, substrate_info) over a local-first, signal-scored parse of `~/.claude/projects/`. Per-pair scores are numpy columns on disk, not opaque vectors in a service. Zero outbound calls (CI-enforced).

Compressed Knowledge Graphs (pre-structured dependency DAGs) as MCP context — agents traverse declared edges instead of inferring from text. Open CKG Benchmark (64 domains, 10,838 queries): 3.8× RAG's F1 at 11× fewer tokens, ~42× RDS, 0 fabricated edges by construction. 97 domains, 4 tools, no DB/embeddings. `pip install ckg-mcp`

Event-sourced agent memory on a hash-chained append-only log with an embedded temporal knowledge graph (Kuzu, no sidecar). Cited Memory Checkout context, salience-based forgetting that attenuates instead of deleting, compaction-recovery hooks for Claude Code, token-budgeted checkout, and review-gated consolidation. 47 MCP tools with an 8-tool core profile default. `pip install zaxy-memory` [Docs](https://docs.zaxy.io)

Russian court practice (Sudact): case search by article, court, instance and dates; full decision text.

MCP server for RAGStack serverless knowledge bases. Search, chat with AI-generated answers, upload documents/media, scrape websites, and analyze metadata through an AWS-powered RAG pipeline (Lambda, Bedrock, S3, DynamoDB).

MCP server for the RegIntel API: structured regulatory data across 41 jurisdictions and 212 regulations (GDPR, MiCA, DORA, SEC, FINRA, FCA, APRA, ASIC, MAS). Tools for search, lookup, recent updates, and compliance checks.

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`

Hosted memory that learns and forgets — feedback re-ranks what helps, recall fades by recency, similar memories consolidate. One key across Claude, Cursor, VS Code & ChatGPT.

EU AI Act compliance scanner that detects regulatory violations in AI codebases with risk classification and remediation guidance.

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`
