About ContextStream
ContextStream gives AI coding agents shared project context over one hosted MCP endpoint. Tools cover hybrid semantic plus keyword code search over indexed project files, saved decisions, lessons, plans and runbooks scoped to workspaces and projects, and session handoffs so the next agent session (in any supported client) starts with the same context. Works with Cursor, Claude Code, Codex, Windsurf, Cline and any MCP client. Auth: OAuth 2.1 on the hosted Streamable HTTP endpoint, or an API key with the npm package (npx -y @contextstream/mcp-server). Listed in the official MCP Registry as io.contextstream/mcp. Free Starter tier, no card required; paid plans for heavier use. Published benchmarks with methods: https://contextstream.io/benchmarks
