# Brainy Augmentations
|
||||
|
||||
</div>
|
||||
|
||||
This directory contains the augmentation implementations for Brainy. Augmentations are pluggable components that extend
|
||||
Brainy's functionality in various ways.
|
||||
|
||||
## Available Augmentations
|
||||
|
||||
### Conduit Augmentations
|
||||
|
||||
Conduit augmentations provide data synchronization between Brainy instances.
|
||||
|
||||
#### WebSocketConduitAugmentation
|
||||
|
||||
A conduit augmentation that syncs Brainy instances using WebSockets. This is used for syncing between browsers and
|
||||
servers, or between servers.
|
||||
|
||||
```javascript
|
||||
import { createConduitAugmentation, augmentationPipeline } from '@soulcraft/brainy'
|
||||
|
||||
// Create a WebSocket conduit augmentation
|
||||
const wsConduit = await createConduitAugmentation('websocket', 'my-websocket-sync')
|
||||
|
||||
// Register the augmentation with the pipeline
|
||||
augmentationPipeline.register(wsConduit)
|
||||
|
||||
// Connect to another Brainy instance
|
||||
const connectionResult = await wsConduit.establishConnection(
|
||||
'wss://your-websocket-server.com/brainy-sync',
|
||||
{ protocols: 'brainy-sync' }
|
||||
)
|
||||
```
|
||||
|
||||
#### WebRTCConduitAugmentation
|
||||
|
||||
A conduit augmentation that syncs Brainy instances using WebRTC. This is used for direct peer-to-peer syncing between
|
||||
browsers.
|
||||
|
||||
```javascript
|
||||
import { createConduitAugmentation, augmentationPipeline } from '@soulcraft/brainy'
|
||||
|
||||
// Create a WebRTC conduit augmentation
|
||||
const webrtcConduit = await createConduitAugmentation('webrtc', 'my-webrtc-sync')
|
||||
|
||||
// Register the augmentation with the pipeline
|
||||
augmentationPipeline.register(webrtcConduit)
|
||||
|
||||
// Connect to a peer
|
||||
const connectionResult = await webrtcConduit.establishConnection(
|
||||
'peer-id-to-connect-to',
|
||||
{
|
||||
signalServerUrl: 'wss://your-signal-server.com',
|
||||
localPeerId: 'my-peer-id',
|
||||
iceServers: [{ urls: 'stun:stun.l.google.com:19302' }]
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
#### ServerSearchConduitAugmentation
|
||||
|
||||
A specialized conduit augmentation that provides functionality for searching a server-hosted Brainy instance and storing
|
||||
results locally. This allows you to:
|
||||
|
||||
- Search a server-hosted Brainy instance from a browser
|
||||
- Store the search results in a local Brainy instance
|
||||
- Perform further searches against the local instance without needing to query the server again
|
||||
- Add data to both local and server instances
|
||||
|
||||
```javascript
|
||||
import {
|
||||
ServerSearchConduitAugmentation,
|
||||
createServerSearchAugmentations,
|
||||
augmentationPipeline
|
||||
} from '@soulcraft/brainy'
|
||||
|
||||
// Using the factory function (recommended)
|
||||
const { conduit, activation, connection } = await createServerSearchAugmentations(
|
||||
'wss://your-brainy-server.com/ws',
|
||||
{ protocols: 'brainy-sync' }
|
||||
)
|
||||
|
||||
// Register the augmentations with the pipeline
|
||||
augmentationPipeline.register(conduit)
|
||||
augmentationPipeline.register(activation)
|
||||
|
||||
// Search the server and store results locally
|
||||
const serverSearchResult = await conduit.searchServer(
|
||||
connection.connectionId,
|
||||
'your search query',
|
||||
5 // limit
|
||||
)
|
||||
|
||||
// Search the local instance
|
||||
const localSearchResult = await conduit.searchLocal('your search query', 5)
|
||||
|
||||
// Perform a combined search (local first, then server if needed)
|
||||
const combinedSearchResult = await conduit.searchCombined(
|
||||
connection.connectionId,
|
||||
'your search query',
|
||||
5
|
||||
)
|
||||
|
||||
// Add data to both local and server
|
||||
const addResult = await conduit.addToBoth(
|
||||
connection.connectionId,
|
||||
'Text to add',
|
||||
{ /* metadata */ }
|
||||
)
|
||||
```
|
||||
|
||||
### Activation Augmentations
|
||||
|
||||
Activation augmentations dictate how Brainy initiates actions, responses, or data manipulations.
|
||||
|
||||
#### ServerSearchActivationAugmentation
|
||||
|
||||
An activation augmentation that provides actions for server search functionality. This works in conjunction with the
|
||||
ServerSearchConduitAugmentation to provide a complete solution for browser-server search.
|
||||
|
||||
```javascript
|
||||
import {
|
||||
ServerSearchActivationAugmentation,
|
||||
createServerSearchAugmentations,
|
||||
augmentationPipeline
|
||||
} from '@soulcraft/brainy'
|
||||
|
||||
// Using the factory function (recommended)
|
||||
const { conduit, activation, connection } = await createServerSearchAugmentations(
|
||||
'wss://your-brainy-server.com/ws',
|
||||
{ protocols: 'brainy-sync' }
|
||||
)
|
||||
|
||||
// Register the augmentations with the pipeline
|
||||
augmentationPipeline.register(conduit)
|
||||
augmentationPipeline.register(activation)
|
||||
|
||||
// Use the activation augmentation to search the server
|
||||
const serverSearchAction = activation.triggerAction('searchServer', {
|
||||
connectionId: connection.connectionId,
|
||||
query: 'your search query',
|
||||
limit: 5
|
||||
})
|
||||
|
||||
if (serverSearchAction.success) {
|
||||
// The data property contains a promise that will resolve to the search results
|
||||
const serverSearchResult = await serverSearchAction.data
|
||||
console.log('Server search results:', serverSearchResult)
|
||||
}
|
||||
|
||||
// Other available actions:
|
||||
// - 'connectToServer': Connect to a server
|
||||
// - 'searchLocal': Search the local instance
|
||||
// - 'searchCombined': Search both local and server
|
||||
// - 'addToBoth': Add data to both local and server
|
||||
```
|
||||
|
||||
## Using the Augmentation Pipeline
|
||||
|
||||
The augmentation pipeline provides a way to execute augmentations based on their type.
|
||||
|
||||
```javascript
|
||||
import { augmentationPipeline } from '@soulcraft/brainy'
|
||||
|
||||
// Execute a conduit augmentation
|
||||
const conduitResults = await augmentationPipeline.executeConduitPipeline(
|
||||
'methodName',
|
||||
[arg1, arg2, ...],
|
||||
{ /* options */ }
|
||||
)
|
||||
|
||||
// Execute an activation augmentation
|
||||
const activationResults = await augmentationPipeline.executeActivationPipeline(
|
||||
'methodName',
|
||||
[arg1, arg2, ...],
|
||||
{ /* options */ }
|
||||
)
|
||||
```
|
||||
|
||||
## Creating Custom Augmentations
|
||||
|
||||
To create a custom augmentation, implement one of the augmentation interfaces:
|
||||
|
||||
- `ISenseAugmentation`: For processing raw data
|
||||
- `IConduitAugmentation`: For data synchronization
|
||||
- `ICognitionAugmentation`: For reasoning and inference
|
||||
- `IMemoryAugmentation`: For data storage
|
||||
- `IPerceptionAugmentation`: For data interpretation and visualization
|
||||
- `IDialogAugmentation`: For natural language processing
|
||||
- `IActivationAugmentation`: For triggering actions
|
||||
|
||||
Example:
|
||||
|
||||
```javascript
|
||||
import { AugmentationType, IActivationAugmentation } from '@soulcraft/brainy'
|
||||
|
||||
class MyCustomActivation implements IActivationAugmentation {
|
||||
readonly
|
||||
name = 'my-custom-activation'
|
||||
readonly
|
||||
description = 'My custom activation augmentation'
|
||||
enabled = true
|
||||
|
||||
getType(): AugmentationType {
|
||||
return AugmentationType.ACTIVATION
|
||||
}
|
||||
|
||||
async initialize(): Promise<void> {
|
||||
// Initialization code
|
||||
}
|
||||
|
||||
async shutDown(): Promise<void> {
|
||||
// Cleanup code
|
||||
}
|
||||
|
||||
async getStatus(): Promise<'active' | 'inactive' | 'error'> {
|
||||
return 'active'
|
||||
}
|
||||
|
||||
triggerAction(actionName: string, parameters
|
||||
|
||||
?:
|
||||
|
||||
Record<string, unknown>
|
||||
|
||||
):
|
||||
|
||||
AugmentationResponse<unknown> {
|
||||
// Implementation
|
||||
}
|
||||
|
||||
generateOutput(knowledgeId: string, format: string): AugmentationResponse<string | Record<string, unknown
|
||||
|
||||
>> {
|
||||
// Implementation
|
||||
}
|
||||
|
||||
interactExternal(systemId
|
||||
:
|
||||
string, payload
|
||||
:
|
||||
Record < string, unknown >
|
||||
):
|
||||
AugmentationResponse < unknown > {
|
||||
// Implementation
|
||||
}
|
||||
}
|

# Model Control Protocol (MCP) for Brainy
|
||||
|
||||
This document provides information about the Model Control Protocol (MCP) implementation in Brainy, which allows external models to access Brainy data and use the augmentation pipeline as tools.
|
||||
|
||||
## Components
|
||||
|
||||
The MCP implementation consists of three main components:
|
||||
|
||||
1. **BrainyMCPAdapter**: Provides access to Brainy data through MCP
|
||||
2. **MCPAugmentationToolset**: Exposes the augmentation pipeline as tools
|
||||
3. **BrainyMCPService**: Integrates the adapter and toolset, providing WebSocket and REST server implementations for external model access
|
||||
|
||||
## Environment Compatibility
|
||||
|
||||
### BrainyMCPAdapter
|
||||
|
||||
The `BrainyMCPAdapter` has no environment-specific dependencies and can run in any environment where Brainy itself runs, including:
|
||||
|
||||
- Browser environments
|
||||
- Node.js environments
|
||||
- Server environments
|
||||
|
||||
### MCPAugmentationToolset
|
||||
|
||||
The `MCPAugmentationToolset` also has no environment-specific dependencies and can run in any environment where Brainy itself runs, including:
|
||||
|
||||
- Browser environments
|
||||
- Node.js environments
|
||||
- Server environments
|
||||
|
||||
### BrainyMCPService
|
||||
|
||||
The `BrainyMCPService` has been refactored to separate the core functionality from the Node.js-specific server functionality:
|
||||
|
||||
1. **Core Functionality**: The core request handling functionality (`handleMCPRequest`) can run in any environment where Brainy itself runs. This is what remains in the main Brainy package.
|
||||
|
||||
2. **Server Functionality**: The WebSocket and REST server functionality is not included in the main Brainy package to keep the browser bundle lightweight and avoid Node.js-specific dependencies. In browser or other environments, you can use the core functionality through the `handleMCPRequest` method.
|
||||
|
||||
## Usage
|
||||
|
||||
### In Any Environment (Browser, Node.js, Server)
|
||||
|
||||
```typescript
|
||||
import { BrainyData, BrainyMCPAdapter, MCPAugmentationToolset } from '@soulcraft/brainy'
|
||||
|
||||
// Create a BrainyData instance
|
||||
const brainyData = new BrainyData()
|
||||
await brainyData.init()
|
||||
|
||||
// Create an MCP adapter
|
||||
const adapter = new BrainyMCPAdapter(brainyData)
|
||||
|
||||
// Create a toolset
|
||||
const toolset = new MCPAugmentationToolset()
|
||||
|
||||
// Use the adapter to access Brainy data
|
||||
const response = await adapter.handleRequest({
|
||||
type: 'data_access',
|
||||
operation: 'search',
|
||||
requestId: adapter.generateRequestId(),
|
||||
version: '1.0.0',
|
||||
parameters: {
|
||||
query: 'example query',
|
||||
k: 5
|
||||
}
|
||||
})
|
||||
|
||||
// Use the toolset to execute augmentation pipeline tools
|
||||
const toolResponse = await toolset.handleRequest({
|
||||
type: 'tool_execution',
|
||||
toolName: 'brainy_memory_storeData',
|
||||
requestId: toolset.generateRequestId(),
|
||||
version: '1.0.0',
|
||||
parameters: {
|
||||
args: ['key1', { some: 'data' }]
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
|
||||
### In Browser Environment (Core Functionality Only)
|
||||
|
||||
```typescript
|
||||
import { BrainyData, BrainyMCPService } from '@soulcraft/brainy'
|
||||
|
||||
// Create a BrainyData instance
|
||||
const brainyData = new BrainyData()
|
||||
await brainyData.init()
|
||||
|
||||
// Create an MCP service (server functionality will be disabled in browser)
|
||||
const mcpService = new BrainyMCPService(brainyData)
|
||||
|
||||
// Use the core functionality
|
||||
const response = await mcpService.handleMCPRequest({
|
||||
type: 'data_access',
|
||||
operation: 'search',
|
||||
requestId: mcpService.generateRequestId(),
|
||||
version: '1.0.0',
|
||||
parameters: {
|
||||
query: 'example query',
|
||||
k: 5
|
||||
}
|
||||
})
|
||||

/**
|

* 🧠 Pre-compute Pattern Embeddings Script
|
||||
*
|
||||
* This script pre-computes embeddings for all patterns and saves them to disk.
|
||||
* Run this once after adding new patterns to avoid runtime embedding costs.
|
||||
*
|
||||
* How it works:
|
||||
* 1. Load all patterns from library.json
|
||||
* 2. Use Brainy's embedding model to encode each pattern's examples
|
||||
* 3. Average the example embeddings to get a robust pattern representation
|
||||
* 4. Save embeddings to patterns/embeddings.bin for instant loading
|
||||
*
|
||||
* Benefits:
|
||||
* - Pattern matching becomes pure math (cosine similarity)
|
||||
* - No embedding model calls during query processing
|
||||
* - Patterns load instantly with pre-computed vectors
