The context layer your AI agents were missing.
Ceiling indexes your codebase into a structured vault, keeps a living context page your agents can read and write, and exposes everything through a single MCP server — so every coding session starts with full project awareness.
How it works
Connect GitHub
Authorize a repo. Ceiling indexes it into a structured vault — entity pages, concepts, architecture notes, and context pages your agents can read.
Install the MCP server
One command wires ceiling into Claude Code and Cursor. Agents call get_task_context before any task and get scoped, up-to-date project context.
File session notes
At the end of each session your agent files decisions, architecture changes, and a session summary back into the vault. The next session picks up where you left off.
What you get
Vaults
Auto-indexed knowledge bases built from your GitHub repos. Entities, concepts, and source pages — all searchable.
Context pages
Agent-writable memory. Active priorities, constraints, recent decisions, and known risks — always in sync.
Research
Deep research reports grounded in vault knowledge and the web. Cited, structured, and stored.
Hybrid search
Semantic + keyword search over all indexed sources. Ranked passages with heading trail and page provenance.
Self-host or use the cloud.
