## Description
Build, validate, simulate, and deploy walkerOS event pipelines

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

```json
"mcpServers": {
  "walkeros-flow": {
    "command": "npx",
    "args": ["-y","walkeros"]
  }
}
```

## Documentation

## What the walkerOS Flow MCP server does

The walkerOS Flow MCP server gives MCP-compatible AI agents access to walkerOS event-pipeline workflows. Its documented local workflow includes loading a flow, checking whether its configuration is valid, and simulating an event. These operations let a developer test collection behavior before wiring a production source or destination.

walkerOS is an event collection layer built around sources, a collector, and destinations. Sources can include browser code, data layers, Express applications, AWS Lambda, and GCP Functions. The collector handles processing such as consent, validation, mapping, routing, and enrichment. Destinations include GA4, Google Ads, Meta CAPI, BigQuery, and other supported packages.

The MCP interface also supports agent-assisted work with event schemas. Agents can read a schema, suggest tracking definitions, and generate integration code.

## How it works

The walkerOS Flow MCP server runs locally through the `@walkeros/mcp` package. An MCP client starts it with `npx`, then communicates with the process using the client’s MCP configuration. Flow loading, validation, and event simulation do not require a walkerOS account.

A flow can be used in either an integrated or bundled walkerOS setup. Integrated mode imports `startFlow` into a TypeScript application. Bundled mode uses a JSON flow definition and the `npx walkeros bundle flow.json` command to produce a standalone script.

## Setup and configuration

For clients other than Claude Code, add a server entry that starts `@walkeros/mcp` with `npx`:

```json
{
  "mcpServers": {
    "walkeros-flow": {
      "command": "npx",
      "args": ["@walkeros/mcp"]
    }
  }
}
```

Claude Code can install the walkerOS plugin from the project marketplace with `/plugin marketplace add elbwalker/walkerOS`, followed by `/plugin install walkeros@elbwalker`. The repository also documents a separate browser-source MCP server, `@walkeros/mcp-source-browser`; that component is not the flow server itself.

## Tools and capabilities

The documented capabilities include:

- Load walkerOS flow configuration locally.
- Validate flow definitions and their configuration.
- Simulate events against a flow.
- Read event schemas for agent-assisted tracking work.
- Suggest tracking definitions.
- Generate integration code.

The broader walkerOS project supports configuration as code, declarative tagging, consent-aware event queuing, schema validation, routing, and multiple destinations. Whether a specific capability is available through the flow MCP process should be checked against the current MCP documentation.

## Limitations and notes

It also does not document environment variables for this server. Local flow operations are explicitly described as requiring no account, but destination credentials or external service configuration may still be needed when implementing a real pipeline.

The repository is MIT licensed. Documentation for the MCP application is available at the walkerOS documentation site under the MCP section.
