In their own words
Knit
Knit brings together a Unified API, an Integrations Agent, and MCP servers for building software integrations and workflows. The Unified API provides normalized data models, read and write access, and two-way syncs across product integrations. The Integrations Agent converts natural-language workflow descriptions into custom integration code that can be deployed and monitored. Knit’s MCP servers offer AI agents managed-auth access to more than 190 apps without customer-managed infrastructure. Its directory lists 194 integrations, including Salesforce, HubSpot, QuickBooks, Workday, BambooHR, Asana, Gmail, and Jira. The service supports Android, iOS, web, and API use. Knit says it does not keep end-user data on its servers, encrypts data at rest with AES-256 and in transit with TLS 1.3, and complies with SOC 2, GDPR, and ISO 27001. Data processing residency is available in the US, EU, and India. There is a free plan and a 30-day trial; paid plans include Starter at $29 a month and Professional at $99 a month.
