Best Authentication Software for Linear

Scalekit is the MCP gateway for AI agents. Developers and platform teams use it when an agent must call business tools as the user, not through a shared service account. One endpoint reaches 600+ connectors and 35,000+ tools, including Salesforce, Gmail, Slack, Notion, HubSpot, Jira, and GitHub. When the agent requests a tool, Scalekit finds that user's credentials, checks that the agent is allowed to call it, runs the call, and returns a clean response. Tokens stay in an AES-256 vault, isolated per tenant, and out of application code, logs, and the model prompt. Venu Madhav Kattagoni, Head of Engineering at Von, describes it this way: "Our agents act across Salesforce, Gong, Google Drive, and more, on behalf of every customer." Scalekit works with Anthropic, OpenAI, LangChain, Google ADK, Vercel AI, and Mastra. Managed cloud runs in the US (Los Angeles) or the EU (Frankfurt). EU data residency on Growth is a $99 a month add-on. Enterprise can run in a VPC or self-hosted, including air-gapped. Scalekit is SOC 2 Type II and ISO 27001 certified. A HIPAA BAA is available on Enterprise. The Free plan is $0 a month and includes 10,000 tool calls and 10,000 trigger events. Growth is $99 a month for 100,000 tool calls, then $0.50 per 1,000 calls. Enterprise pricing is custom, and includes SSO and SCIM for the Scalekit dashboard
