Waggle is an open-source, local-first memory layer for AI agents. It stores project knowledge as a graph: what you decided, why it matters, what it depends on, and what has changed. Your next conversation can pick up from that context instead of starting over.
Use Waggle with your MCP client, inspect and edit memory in Graph Studio, or bring a portable memory graph into the browser workspace.

does not require a Waggle account or an external database.
The Python package requires Python 3.11+ and pipx. On macOS, you can install pipx with brew install pipx; see the installation guide for client-specific options.
pipx install waggle-mcp
pipx ensurepathRestart your terminal after the first pipx ensurepath, then run:
waggle-mcp setup --yes
waggle-mcp doctorRestart your MCP client to load Waggle. Setup detects supported clients and writes their configuration; automatic memory behavior uses the client's installed hooks, skills, or project instructions.
To check continuity, ask your agent to remember a project decision, then open a fresh session in the same project and ask what was decided. Keep the same project identifier across sessions.
| Client | Setup guide |
|---|---|
| Codex | Install the Waggle plugin or configure the MCP server |
| Claude Code | MCP server and automatic memory hooks |
| Claude Desktop | Desktop extension and manual configuration |
| VS Code | Waggle extension and workspace setup |
| Cursor | Connect the local MCP server |
| Antigravity | Client configuration |
| Other MCP clients | Standard MCP configuration |
| ChatGPT with Site tools | Use the browser workspace |
For clients that accept an mcpServers configuration:
{
"mcpServers": {
"waggle": {
"command": "waggle-mcp",
"args": ["serve", "--transport", "stdio"]
}
}
}If the command is not found, run pipx ensurepath and reopen your terminal. Use the troubleshooting guide for installation, startup, and client connection issues.
Waggle separates durable project knowledge from the model's context window. An agent retrieves relevant memory when needed and records meaningful outcomes for later conversations.
The core MCP workflow uses prime_context to load project context, query_graph to retrieve relevant history, and observe_conversation to record durable outcomes. build_context assembles a compact context pack for a specific task. Tool availability alone does not make an agent use memory automatically; its hooks, skills, or instructions must call these tools.
See the tool reference and configuration reference for the full API and retrieval settings.
Graph Studio makes project memory inspectable and editable. Browse nodes and relationships, add or remove graph content, inspect source evidence, and review how a memory changed over time.
The browser workspace provides focused views for project context, memories, proposals, and activity. Graph Studio provides the graph-level view of that server-backed memory; private browser imports remain in the workspace tab.
[Open Graph Studio](https://waggle-webmcp.onrender.com/graph)
The Waggle workspace lets a human and a compatible browser agent work with the same project memory. Its WebMCP adapter registers page-level Site tools through document.modelContext.registerTool. This is separate from installing Waggle's MCP server or configuring a remote MCP connector.

For example:
Call Waggle's get_project_brief with project_id "waggle-webmcp".
Use the returned memories to catch me up on this project.If Site tools are unavailable, check the browser's permissions and configuration. If the browser blocks an apply call, you can use Apply approved change on the approved proposal and confirm the action yourself. This uses the same approval and freshness checks; it does not bypass browser safeguards.
| Tool | What it does |
|---|---|
get_project_brief | Returns the project's goal, current decisions, constraints, state, and open questions. |
recall_memory | Finds current authoritative memories for a query, with supersession provenance when available. |
propose_memory_change | Creates a pending correction for human review without changing authoritative memory. |
apply_approved_memory_change | Applies the exact approved value using only a proposal ID. |
load_abhi_for_session | Loads a portable graph into this browser tab and returns a brief. |
flowchart LR
A[Agent proposes a correction] --> B[Human reviews and approves]
B --> C[Waggle checks approval and target version]
C --> D[Approved value becomes authoritative]
D --> E[Previous memory stays in history]Approved content cannot be changed by the applying agent. If the target memory has changed since the proposal was created, the proposal is marked stale instead of overwriting newer information. Application preserves the previous memory and links it to the replacement with an updates edge.
These approval rules govern the WebMCP correction workflow. They are not a claim that every direct graph-editing or local MCP operation requires approval.

expanded.
proposals, and approvals now use that imported copy.
The import replaces this tab's active workspace; it does not merge with the sample graph, modify your original file, or affect another visitor.
You can also attach the file to a compatible chat and ask:
Use Waggle's load_abhi_for_session tool to load this .abhi file into
project "waggle-webmcp" for this session. Then call get_project_brief.The agent must be able to read the attachment and provide its bytes as base64. The tool does not accept a local file path or download URL. Use the page's file picker if the chat cannot access the attachment.
See the portable memory format for archive structure and supported operations.
| Where you use Waggle | Where memory lives |
|---|---|
| Local MCP server | SQLite on your machine, at ~/.waggle/waggle.db by default. |
| Private browser import | This tab's sessionStorage; the importer does not upload the graph to Waggle's backend. |
| Hosted sample workspace | An isolated, temporary server-side sample project; not an account-based cloud backup. |
| Self-hosted remote MCP server | Your configured Neo4j backend and infrastructure. |
Browser lifetime. Private imports survive page reloads, and browser session restoration can preserve them. Use the workspace's Reset Demo control to explicitly clear the private copy and return to the sample project. Closing a chat conversation alone is not a guaranteed deletion signal. Browser storage is not encrypted by the importer.
AI services. Attaching a file in chat shares it with that chat provider. Memory returned through tool calls is also shared with the requesting AI service. Local storage does not mean that model inputs stay on your device.
Hosted preview. The public workspace is for trying the browser experience, not durable production storage. Its free hosting can pause when idle, take time to wake, and lose sample state on restart or redeployment. Opening it does not connect to your local Waggle database. The included SQLite preview configuration stores disposable state under /tmp, caps admission at 128 sessions per database, and rejects new sessions at capacity without evicting existing ones.
Self-hosting. The browser preview's governance backend currently requires SQLite. Remote MCP hosting with Neo4j is a separate configuration, not a drop-in replacement for that browser workflow. For remote deployment, configure HTTPS, authentication, persistent storage, and backups. Read the production deployment guide, security model, and hardening checklist before exposing a server publicly.
Waggle uses Python for the memory engine and MCP server, and React/Vite for Graph Studio and the browser workspace.
