Documentation

Persistent context for AI-assisted technical work.

ContextStream gives your AI tools persistent memory, semantic search, and knowledge graphs — without bloating prompts. Start with MCP (recommended) or integrate directly via the API.

Integrations

GitHub, Slack, Notion — let ContextStream read decisions where they're already happening.

Read

Memory Events

Decisions, lessons, preferences, guardrails, sessions — the primitives ContextStream stores.

Read

Doc Types

22 markdown flavours — runbooks, ADRs, RFCs, postmortems, retros, PRDs, personas, glossaries, and more.

What ContextStream is

A memory and context platform for AI tools.

Persistent Memory

Decisions, lessons, and context survive across sessions, teams, and tools — automatically scoped.

Semantic Search

Search by meaning. Find the right decision or lesson in milliseconds, not by remembering the right keyword.

Knowledge Graphs

Decisions, code, and docs linked into a queryable graph. Trace the reasoning behind any change.

MCP-Native

First-class integration with Claude, Cursor, VS Code, Codex, and every other MCP-aware editor or agent.

How it works

Two commands, then ask naturally.

terminal · contextstream-mcp

# 1) Run the setup wizard
# macOS / Linux:
curl -fsSL https://contextstream.io/scripts/mcp.sh | bash

# Windows (PowerShell):
irm https://contextstream.io/scripts/mcp.ps1 | iex

# 2) Ask naturally in your AI tool
"session summary"
"remember we're using PostgreSQL"
"what did we decide about auth?"

Prefer manual setup? See MCP Integration for the per-client config format.

Tools at a glance

~11 domain tools, action-dispatched.

Hybrid pattern, keyword, and semantic search across memory + code.

memory

Decisions, lessons, docs, todos — captured and queryable.

session

Recall, lessons, plans, and snapshots from past work.

graph

Knowledge graph, file/code dependencies, and impact analysis.

capsule

Portable, scoped context bundles — share or hand off.

skill

Reusable instruction + action workflows that persist across sessions.
