"A local knowledge base" matching MCP connectors:

Analytical memory for AI agents: a real Postgres queried in plain English over MCP. One command.

A connector providing AI assistants searchable access to climate-aligned contract clauses, glossary terms, and practical guides from The Chancery Lane Project's curated knowledge graph.

Loads your personal writing voice into any AI and scores how closely a draft matches it.

Open scientific and engineering knowledge for AI agents: search, evidence, document publishing.

Push Realm is an MCP server and AI agent knowledge network where agents search proven fixes, publish what worked, and turn dead ends into open problems other agents can close. Compare how agents and tools perform in different topic areas.

Public, read-only MCP over the complete 64-hexagram I Ching corpus. Deterministic lookup only.

Zero-Ops deploy of a private AI coding workspace onto your own VPS — straight from your AI chat. Provide only your Ubuntu server credentials and Fractera automatically configures everything (Nginx, HTTPS, auth, database, services) in about 10 minutes: 5 AI coding engines, an autonomous Hermes orchestrator, and private graph memory (LightRAG). No terminal, no DevOps. IP-first and free; a custom domain with HTTPS is an optional later step.

Shared long-term memory vault for AI agents with 20 MCP tools.

Shared memory for AI agents. One address per fact, one signature you check. No key to read.

**ColdState Knowledge Search MCP Server** https://github.com/daniel-coldstate/coldstate-mcp Semantic search over 64.6M knowledge entries — the structured alternative to web search APIs and web scraping for LLM agents. No crawling, no rate limits, sub-3s responses. Cloud-hosted at services.coldstate.ai

A portable knowledge-graph memory you pass in and get back. No database. 4 of 6 free.

Public NFH knowledge, ownership epochs, versioned learning, Odd Jobs, and unsigned preparation.

Recall (recall.it) — your AI knowledge base / 'second brain'. Via the official API: semantic search

Manage AI assistants, history, calls, campaigns, contacts, knowledge, messaging, and automations.

FastMCP server for TheBrain API — AI access to a personal knowledge graph, Tollbooth-monetized

Your private knowledge base: upload documents (.md, .txt, .docx, PDF, images), the platform indexes

Verifiable cognition: any agent file to a deterministic content-addressed brain_id.

Cross-session, cross-device memory for your agent: remember and recall notes. No key to start.

A field station for AI agents: free memory, a message board, a peer oracle, an open census.

MCP server for The Chancery Lane Project's climate-aligned contract clause knowledge graph.
