450+ Connectors, 28,000+ Actions
ConnectOne connection gives your agent 28,000+ tools across 450+ enterprise apps — compatible with 60+ AI clients & frameworks.
As a company rooted in security assurance, we needed a partner sharing our priorities. StackOne's approach gave us confidence to scale without compromise.

Without Pre-Built Connectors? Missing or thin MCP servers, designed for generic use-cases, not your workflows. Every call is a gamble.
Pre-Built Connectors
450+ connectors and 28,000+ actions — 100k+ evals using real agent prompts to guarantee their quality.
Without Managed Auth? OAuth flows, token refresh, key rotation — all yours to build, debug, and maintain. In every single integration.
Managed Authentication
OAuth, SAML, API keys, scopes — StackOne handles authentication into all your tools in a single interface.
AI Connector Builder
Build custom connectors or actions for any API in minutes — so you can cover any use-case.
Works with all your AI tools
Connect in minutes via MCP, A2A, or our API to where all your agents are built — Claude, Microsoft Copilot, Gemini, ChatGPT, Glean, and more.
AI Agent Webhooks
Trigger agentic workflows on any app event — filtered, enriched, and trimmed so your agent can act. No polling.
Without AI Connector Builder? Your coding assistant wasn't built for integrations. It guesses, skips edge cases, and ships code that breaks. You have to handle versioning, testing, and teaching your agent complex APIs.
AI Connector Builder
Build custom connectors or actions for any API in minutes — so you can cover any use-case.
Without Multi-Protocol? Agents are being built everywhere. Investing in a gateway that doesn't support all agentic interfaces leaves you exposed, and limits adoption.
Works with all your AI tools
Connect in minutes via MCP, A2A, or our API to where all your agents are built — Claude, Microsoft Copilot, Gemini, ChatGPT, Glean, and more.
Without AI Agent Webhooks? Agent polls on a loop, parses raw payloads, hunts for the one event that matters — burning calls and tokens just to react late.
AI Agent Webhooks
Trigger agentic workflows on any app event — filtered, enriched, and trimmed so your agent can act. No polling.

Without Prompt Injection Guard? People increasingly let agents act on their behalf. Yet every email, doc, and tool response is another attack surface for prompt injection. Your agent is one hidden instruction away from leaked data and actions you never approved.
Prompt Injection Guard
StackOne's Prompt Injection Guard catches 89% of malicious tool responses before your agent sees them.
Without Granular Permissions? Every agent gets every tool. No way to limit the data one user's agent can reach or act on.
Action, Field & User-Level Permissions
Scope which tools each user's agent can use. Customize fields returned by tools. Grant access per user. Agents can only ever touch what you've allowed.
Observability
Complete visibility into every action your agent takes — request tracing, audit logs, and real-time monitoring.
Secure Deployment
Run in any region, with real-time processing and no customer data stored by default.
Without Observability? No visibility into the actions agents take and data they access across your organization. Impossible to meet compliance requirements for sensitive data.
Observability
Complete visibility into every action your agent takes — request tracing, audit logs, and real-time monitoring.
Without Secure Deployment? No ability to choose where the data gets processed — no ability to match your organization's data compliance and security requirements.
Secure Deployment
Cloud-based, or self-hosted. Select any region in AWS, GCP, or Azure to process your data.

Without Tool Discovery? You load tool schemas you don't need, burn tokens, and pray your agent picks the right tool call for your users.

Tool Discovery
Give your agent powerful search across all its tools, instead of front-loading them in the context window.
Without Data Sync? Agents have to slowly paginate through large data, and load everything in their context window. Extremely token-expensive — and often impossible for agents to run analytics on large-scale data.
Underlying API
- List Records Underlying API
- Search Records Data Sync
- Filter Records Data Sync
- Sort Records Data Sync
- Query Records Data Sync
Managed Data Sync
StackOne can pre-sync data and exposes search, filtering, sorting, and querying capabilities to your agent that are not available in the underlying APIs.
Without Falcon Execution Engine? Agents struggle to use poorly designed MCPs, waste tokens on actions designed in the API era, and fail to automate your workflows.
Falcon Execution Engine
Our self-improving integration engine, optimized for agentic tool calling — actions that agents get right the first time, execute tasks faster, and use fewer tokens.
Context Bloat Makes Your Agent Slow, Costly, and Unreliable
Recognized for performance. Loved for simplicity.
