LMS (LGC MCP Server) is a multi-tenant Model Context Protocol (MCP) server that lets an organization operate its Google Workspace, Slack, Notion, social, and cloud tooling through AI assistants like Claude.

LMS exposes an organization's connected business systems as tools an AI assistant can call directly. Instead of switching between apps, a person asks their AI assistant in plain language, and LMS carries out the action against the real system.
Each integration is real read/write access to a live system, not a demo or mock data source. A command like "email the invoice to this client and update the CRM" is executed by LMS calling the actual Gmail and Sheets/Drive APIs on the tenant's behalf.
LMS is built for any organization to sign up and use, not for a single company. Every customer — from a solo developer to a larger team — signs up as its own Org (tenant) and connects its own accounts and credentials.
LGC, the company that built LMS, uses the product itself as its first customer (Org #1). It is a reference user of a general product, not the boundary of what the product is for.
Each tenant's data is namespaced in the underlying database with logical isolation from other tenants, and each tenant's integration credentials (OAuth tokens, API keys) are stored encrypted, separately per tenant. Each Org manages its own users and its own IT Admin role — one tenant cannot see or act on another tenant's connected accounts.
LMS offers a free trial and paid tiers that scale with the number of seats an Org needs. Additional seats beyond a plan's included count are ¥2,000/seat/month.
| Plan | Seats included | Price |
|---|---|---|
| Free | 1 seat, 14-day trial | ¥0 |
| Pay-as-you-go | 1 seat, per-use | ¥0 |
| Workspace | 3 seats | ¥9,999/mo |
| Developer | 10 seats | ¥39,999/mo |
| Business | 25 seats | ¥79,999/mo |
| Enterprise | Custom deployment | ¥99,999/mo |
LMS is built and operated by LGC — Larry Group Corp (KK), a company based in Tokyo, Japan.
LMS (LGC MCP Server) is a multi-tenant Model Context Protocol (MCP) server that lets an organization operate its Google Workspace, Slack, Notion, social, and cloud tooling through AI assistants like Claude. It exposes each connected system as a set of callable tools an AI assistant can use on the organization's behalf.
LMS is built for any organization, not a single company. Each customer signs up as its own tenant (an Org, from a solo developer with one seat up to larger teams) and connects its own accounts. LGC, the company that built LMS, is itself tenant #1 and uses the product the same way any other customer does.
LMS gives an AI assistant tool access to a tenant's connected systems: Google Workspace (Gmail, Calendar, Drive, Docs, Sheets, Slides), Slack, GitHub, Google Cloud Platform (Cloud Run, Cloud Build, Cloud SQL, Secret Manager, and more), Notion, WordPress, WooCommerce, GoDaddy domains and DNS, Facebook, Instagram, LinkedIn, and Perplexity web search. The assistant reads and writes to these real systems through plain-language commands.
Every tenant is modeled as its own Org. Each tenant's data is namespaced in the shared Firestore database with logical isolation, and each tenant's integration credentials (OAuth tokens, API keys) are stored encrypted, separately from other tenants. Each Org manages its own users and its own IT Admin role rather than sharing access with other tenants.
MCP (Model Context Protocol) is an open protocol that lets an AI assistant call external tools through a standard interface. LMS implements an MCP server: any MCP-compatible AI client (such as Claude Code, Claude Desktop, or Cursor) can connect to a tenant's LMS endpoint and use the tools it exposes.
Create an account at lms.lgc.inc to get an MCP endpoint URL and access token for your organization, then add that endpoint to an MCP-compatible AI assistant. No credit card is required to start on the Free plan.
