Loopthink is a web-based MCP gateway and control plane that lets organizations expose business applications, databases, and REST APIs as tools for AI assistants. It provides prebuilt and custom connectors, routing requests from MCP clients through centralized access policies. Administrators can manage user and tool permissions, authentication, field-level data masking, audit records, and data-loss-prevention rules. Deployment options include Loopthink's managed EU cloud service and self-hosted components for connecting on-premises systems; enterprise options include dedicated or on-premises deployments. Connectors include Salesforce, HubSpot, Google Ads, Google Search Console, PostgreSQL, and Microsoft SQL Server. Teams can use these integrations from AI clients, including Claude and ChatGPT. Plans include a free tier and paid team tiers.

Cotlet is a hosted MCP server and REST API that lets AI agents work with web apps that lack a usable API. Users connect an app and sign in through a personal Chrome browser hosted in the cloud; agents can then call supported read and write actions through MCP, while scripts and backends can use the REST API. Its integration catalog covers tasks such as bookings, travel, customer support, invoicing, and marketing. Cotlet is aimed at developers and teams building agent workflows, as well as automation providers working with clients’ apps. It supports MCP clients including Claude, ChatGPT, Cursor, GitHub Copilot, Gemini, Windsurf, and n8n. Connected apps use the account holder’s signed-in session; Cotlet says it does not store passwords and encrypts browser profiles. Successful calls consume credits, while errors and timeouts do not. The company says integrations are regularly tested and updated when connected apps change.
