MCP support
The MCP server exposes accelerator tools to Claude and other MCP clients, including embedding generation, template generation, and OAuth validation.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
npx -y s2t-mcp-acceleratorsS2T_API_KEYSecretYour S2T Accelerator Platform API key. Get one free at https://dev.s2tconsulting.com/ai-sales/purchase.htmlLocal servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

- 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)

- 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)

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
