Overview

AI-generated overview

Gives an assistant S2T enterprise accelerators: vector embeddings, CloudFormation/SAM template generation, and OAuth configuration validation.

What you can do
Exposes S2T accelerator tools to an assistant. s2t_embed generates vector embeddings for text with automatic chunking, for RAG and semantic search. s2t_generate_cloudformation turns natural-language descriptions into SAM or CloudFormation YAML templates covering Lambda, API Gateway, DynamoDB, S3, SQS, SNS, EventBridge and IAM. s2t_validate_oauth checks OAuth 2.0 settings for common misconfigurations, and s2t_catalog and s2t_usage list accelerators and report quota.
When to use it
Useful when you want an assistant to produce embeddings, draft AWS infrastructure templates, or sanity-check OAuth settings without building those capabilities yourself. It suits teams already working with AWS and S2T accelerators who accept a paid, quota-limited API.
Requirements
Runs locally over stdio, typically via npx from the npm package s2t-mcp-accelerators, so Node.js is needed. A required S2T API key must be supplied in the S2T_API_KEY environment variable; an optional S2T_API_URL can point at a custom endpoint. Network access to the S2T API is required, and the server is desktop-only.
Before you install
The S2T_API_KEY secret is sent to S2T's API, and usage is metered against paid tiers with rate and monthly limits, so calls can incur cost or hit quota. Text submitted to s2t_embed and infrastructure descriptions sent to s2t_generate_cloudformation leave your machine for a third-party service. OAuth validation takes client_id, redirect URIs and scopes as input. Generated templates should be reviewed before deployment.

Installation

In SourceWeft

  1. Open Accelerators in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

S2T Accelerators MCP Server

[npm version] [License: MIT] [MCP Compatible]

MCP server providing Claude with access to S2T's battle-tested enterprise accelerators:

  • Vector Embeddings (ACC-AI-001) - Generate embeddings for RAG, semantic search
  • CloudFormation Generator (ACC-AWS-001) - Generate production-ready SAM/CFN templates
  • OAuth Validator (ACC-INT-001) - Validate OAuth configurations before deployment

Quick Start

1. Install

bash
npm install -g s2t-mcp-accelerators

2. Get an API Key

Visit https://dev.s2tconsulting.com/ai-sales/purchase.html to create an account and get your API key.

3. Configure Claude Desktop

Add to your Claude Desktop config file:

macOS/Linux: ~/.config/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

json
{  "mcpServers": {    "s2t-accelerators": {      "command": "npx",      "args": ["s2t-mcp-accelerators"],      "env": {        "S2T_API_KEY": "sk_live_your_api_key_here"      }    }  }}

Restart Claude Desktop to activate the tools.

Available Tools

s2t_embed

Generate vector embeddings for text. Supports automatic chunking for long documents.

Input:- text: string (required) - Text to embed (max 100,000 characters)- model: "amazon.titan-embed-text-v2:0" | "amazon.titan-embed-text-v1"- chunk_size: number (100-2000, default: 512)- chunk_overlap: number (0-500, default: 50)
Output: Embedding vectors with metadata

Use cases: RAG systems, semantic search, document similarity, knowledge base indexing

s2t_generate_cloudformation

Generate CloudFormation/SAM templates from natural language descriptions.

Input:- description: string (required) - What infrastructure you need (max 5000 chars)- format: "sam" | "cloudformation" (default: sam)- include_parameters: boolean (default: true)- include_outputs: boolean (default: true)
Output: Complete YAML template with best practices

Supported resources: Lambda, API Gateway, DynamoDB, S3, SQS, SNS, EventBridge, IAM

s2t_validate_oauth

Validate OAuth 2.0 configuration and detect common misconfigurations.

Input:- provider: "google" | "microsoft" | "github" | "quickbooks" | "generic"- client_id: string (required)- redirect_uris: string[] (required)- scopes: string[] (required)- token_endpoint: string (optional, for generic)- authorization_endpoint: string (optional, for generic)
Output: Validation results, warnings, recommendations

Detects: Invalid client IDs, insecure redirect URIs, missing scopes, deprecated endpoints

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
