Project memory, semantic code search, and grounded agent context.
Connect your code, docs, and conversations so your agents can find the right files, recall saved decisions, and build on past work across sessions and tools.
10,000 monthly credits. No credit card required.
Works with Claude Code, Cursor, Codex, and other supported MCP clients. Create your account or sign in during MCP onboarding. No separate website signup needed.
macOS and Linux

Ask your connected agent:
Use ContextStream to find the files relevant to my next change. Cite the sources and retrieve any saved project decisions that should guide the work.
Then ask it to save a real decision and its reason. Start a new session and retrieve that decision without explaining it again. Indexing supplies code context; it cannot recover every undocumented decision.
95 ms median code search in our published benchmark. This is the measured successful-response median for the disclosed configuration, not a latency guarantee. See results, methodology, and limitations.
Scoped access. Traceable sources. Configurable capture. Indexing sends eligible source contents to ContextStream for hosted search. Transcript saving and local Git metadata capture are on by default and can be turned off. Review data handling and controls before connecting sensitive projects.
npx -y @contextstream/mcp-server@latest setup
The npm launcher downloads the native Rust binary for your platform and verifies its SHA-256 checksum. Pin an exact package version for production automation.
For clients supporting Streamable HTTP and OAuth, the hosted endpoint is:
https://mcp.contextstream.io/mcp
Use the MCP documentation for your client's configuration and stdio alternatives. A hosted connection alone does not sync your local checkout.
contextstream-mcp setup --dry-run
contextstream-mcp doctor --scope=all --only-configured
This repository contains the MIT-licensed Rust MCP server, client, editor setup, and release tooling. The hosted backend is separate and is not included here. See the architecture, release integrity, and latest release.
cargo build --locked -p mcp-server --bin contextstream-mcp
