[Connapse demo — upload a PDF, search with hybrid vector and keyword search, get results with source citations in seconds]

Your AI agents forget everything between sessions. Connapse fixes that.

Every time you start a new conversation, your AI agent starts from zero — no memory of past research, no access to your documents, no accumulated knowledge. Connapse is an open-source knowledge backend that gives agents persistent, searchable memory. Upload documents or point it at your existing Amazon S3 buckets or local filesystems. Agents query and build their own research corpus through the MCP server, the REST API, or the CLI. Container-isolated, hybrid search (vector + keyword), self-hosted and private. Deploy in 60 seconds with Docker. Built on .NET 10.

📦 Quick Start

You need Docker with the Compose plugin and port 5001 free.

git clone https://github.com/Destrayon/Connapse.gitcd Connapsecp .env.example .envdocker compose --profile with-ollama up -ddocker compose exec ollama ollama pull nomic-embed-text

Open http://localhost:5001 and create the owner account. The full walk-through, from upload to a cited search result, is the Quickstart.

🤖 Connect an agent

Create an agent key at Agents → API Keys, then add Connapse to your MCP client. For Claude Code:

claude mcp add --transport http connapse http://localhost:5001/mcp --header "X-Api-Key: cnp_your_key"

Agents get 21 named tools, such as search_knowledge, upload_file, get_document, the code_* tools and the memory_* tools, plus 3 generic tools that reach the rest of the API. Other clients are in Connect an MCP client, and every tool is in MCP tools.

🚀 Features

• 🗂️ Containers — Each project gets its own files, vector index and optional settings, with nothing shared between containers.
• 🔍 Hybrid search — Vector and keyword search fused together, with optional cross-encoder reranking.
• 🧠 Your choice of models — Ollama, OpenAI, Azure OpenAI and Anthropic, changed at runtime without a restart.
• 🔌 Index what you already have — Uploads, local folders and SFTP, Amazon S3, Azure Blob Storage, GitHub, Confluence and Jira, and your own systems through a custom source server. Files stay where they are.
• 🔐 Per-user permissions — Search results from AWS, Azure, GitHub, Atlassian and custom sources are trimmed to what each person can open in the source system, and fail closed.
• 🤖 Every surface — Web UI, REST API, MCP server and the connapse CLI.
• 🐳 Self-hosted — Docker Compose with PostgreSQL and pgvector, MinIO and optional Ollama. With Ollama, nothing leaves your machine.
