Open-source automation with MCP tool exposure

# Activepieces vs SealGate

How Activepieces and SealGate compare for securing AI agents and their MCP tool calls, and where each one fits.

Last updated: September 2026

Activepieces. Activepieces is an open-source (MIT core) no-code automation platform that can also publish its integration pieces to AI clients as a hosted MCP server, an automation and AI-workflow platform rather than a runtime security firewall.

SealGate. A runtime agentic data firewall that blocks dangerous tool calls before they execute, scans tool traffic for data loss and prompt injection, discovers shadow MCP servers on the device, and streams a provable audit trail to your SIEM.

Bottom line: Activepieces publishes your connected apps to AI clients as MCP tools; SealGate sits on the opposite side of the wire, inline in front of the agent to inspect, scan and block its tool traffic, which Activepieces does not do.

## Activepieces vs SealGate, feature by feature

SealGate leads with the rows at the top, its clearest points of difference, then the parity rows every enterprise gateway is expected to cover.

| Capability | SealGate | Activepieces |
| --- | --- | --- |
| How local stdio MCP servers are handled. Whether your local MCP server stays on the device or is shipped elsewhere. | Tunnel in place (Yes) | Hosted MCP server (No) |
| Local stdio servers stay on-device. The server keeps running on the machine, with no host-and-lift and no HTTP re-expose. | ✓ Yes | ✕ No |
| Device-level management. An endpoint agent that discovers and governs MCP activity on the device itself. | ✓ Yes | ✕ No |
| Interface coverage. Whether the gateway governs only the MCP protocol, or the agent CLI and LLM API too. | MCP + CLI (Yes) | Exposes MCP tools (No) |
| Runtime enforcement. Blocks a dangerous tool call before it executes, not just after the fact. | ✓ Yes | ~ Partial |
| DLP, PII and secrets scanning. Inspects tool inputs and outputs for sensitive data at runtime. | ✓ Yes | ✕ No |
| Prompt injection and tool-poisoning defense. Detects and stops injection, tool poisoning and rug-pull attacks. | ✓ Yes | ✕ No |
| Gateway holds the credential. The gateway issues the final call so the agent cannot bypass policy and retry. | ✓ Yes | ~ Partial |
| Shadow MCP discovery. Finds unauthorized MCP servers before they are used. | ✓ Yes | ✕ No |
| Provable per-call audit. A receipt for every call: agent, tool, policy version, result. | ✓ Yes | ~ Partial |
| SIEM integration and export. Streams audit events to Splunk, Sentinel and other SIEMs. | ✓ Yes | ~ Partial |
| SSO, SCIM and RBAC. Enterprise identity, group sync and role-based access. | ✓ Yes | ✓ Yes |
| Tool-level policy. Read and write tiers, per-tool rules and human-in-the-loop approvals. | ✓ Yes | ~ Partial |
| Self-host, on-prem or VPC. Run it in your own environment for data residency. | ✓ Yes | ✓ Yes |
| Compliance mapping. Evidence mapped to SOC 2, NIST AI RMF and the EU AI Act. | ~ Partial | ~ Partial |
| Low latency overhead. Minimal added latency on the tool-call path. | ✓ Yes | – Not publicly verified |
| Open source core. An open, inspectable core rather than a closed proxy. | ✕ No | ✓ Yes |

## Where SealGate is different

- Activepieces exposes MCP tools (it acts as a hosted MCP server over SSE) but does not secure agent traffic at runtime: no inline DLP, PII or secrets scanning of tool inputs and outputs, no prompt-injection or tool-poisoning defense, and no pre-execution blocking of dangerous tool calls.
- It has no device-level endpoint agent and no shadow-MCP discovery; it governs only the pieces you deploy inside Activepieces, and hosts its own MCP tools in its cloud rather than keeping your local stdio MCP servers on-device via a tunnel.
- Its controls (per-project tool enable and disable, scoped connections, human approval on high-risk actions, audit logs) are automation-platform governance over its own workflows, not a policy firewall inspecting the MCP protocol and agent CLI between an AI client and enterprise tools.
- Credit where due: the core is genuinely open source (MIT), fully self-hostable on Docker, Compose or Kubernetes Helm and air-gap capable, with enterprise SSO, SCIM, RBAC, audit logs and SIEM streaming.

## Frequently asked questions

Doesn't Activepieces' MCP support mean it secures my AI agents? No. Activepieces acts as an MCP server that publishes its connected apps to AI clients as callable tools. It is a tool producer, not a security layer in front of the agent, and it does not inspect, DLP-scan, or block the tool traffic flowing through an agent to other MCP servers or CLIs. That inline runtime firewall role is what SealGate fills.

Is Activepieces self-hostable and open source? Yes. The core is MIT-licensed and self-hostable on Docker, Docker Compose, or Kubernetes Helm, and is air-gap capable. Enterprise features such as SSO, SCIM, custom RBAC and audit-log or SIEM streaming are under a separate commercial license, an open-core model.

Is SealGate a good alternative to Activepieces? Yes. Activepieces is an open-source (MIT core) no-code automation platform that can also publish its integration pieces to AI clients as a hosted MCP server, an automation and AI-workflow platform rather than a runtime security firewall. SealGate is a runtime agentic data firewall that blocks dangerous tool calls before they execute, scans tool traffic for data loss and prompt injection, discovers shadow MCP servers on the device, and streams a provable audit trail to your SIEM. If runtime data security is the priority, SealGate is a strong alternative.

What does SealGate do that Activepieces does not? Activepieces exposes MCP tools (it acts as a hosted MCP server over SSE) but does not secure agent traffic at runtime: no inline DLP, PII or secrets scanning of tool inputs and outputs, no prompt-injection or tool-poisoning defense, and no pre-execution blocking of dangerous tool calls.
