qurio
Qurio is a self-hosted ingestion and retrieval (RAG) engine for AI coding assistants. It crawls or ingests local documents (e.g., web pages, PDFs, Markdown), chunks content structurally, embeds it (Gemini for embeddings), stores vectors/metadata in Weaviate/PostgreSQL, and exposes retrieval to agents via an MCP server over a JSON-RPC 2.0 endpoint.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Runs as a local service behind Docker; README does not specify TLS usage, MCP authentication/authorization, or how requests are protected. API keys (Gemini, optional rerank) must be provided via environment/settings; no guarantees are stated about secret handling in logs. Dependency hygiene and vulnerability posture cannot be verified from provided content.
⚡ Reliability
Best When
You want localhost RAG for coding assistants and can run Docker Compose locally while allowing embedding calls to the configured provider (Gemini) and connecting your agent via MCP.
Avoid When
You need an SDK/OpenAPI-described REST API, strong documented rate limiting, or you cannot provide/secure required API keys (Gemini, optional rerank providers).
Use Cases
- • Grounded documentation search for local development assistants
- • Uploading/crawling internal engineering docs to reduce hallucinations in code generation
- • Providing an MCP tool interface (search/list/read) to agentic coding workflows
- • Hybrid keyword+vector retrieval with optional reranking
Not For
- • Production deployments that require strict enterprise security controls without additional hardening
- • Environments where outbound embedding calls (e.g., Gemini) are not allowed
- • Use cases needing fine-grained section-by-section retrieval (roadmap item)
Interface
Authentication
README describes adding API keys for Gemini and optional rerank providers, but does not describe any authentication/authorization mechanism for accessing the MCP endpoint itself. Treat the MCP endpoint as potentially unauthenticated unless configured otherwise in the code/deployment.
Pricing
Open source (MIT) self-hosted; cost depends on external embedding/reranking providers (e.g., Gemini) and infrastructure (Weaviate/Postgres/Docker). No pricing for the service itself is described.
Agent Metadata
Known Gotchas
- ⚠ MCP tools are described at a high level; exact tool argument schemas/response shapes and pagination/limit behavior are not documented in the provided README.
- ⚠ MCP transport is described as 'stateless, streamable HTTP'; agents may need HTTP MCP client support.
- ⚠ Indexing/ingestion is asynchronous; agents may query before ingestion completes unless the user coordinates workflow via the dashboard/status.
