Use Case Recommendations
Best for: Preloop
Preloop is an Apache-2.0 licensed control plane for AI agents, aimed at the governance problem that appears the moment more than one agent is running in an organisation: nobody can see what tools they can reach, what they are spending, or who approved anything. It bundles six capabilities into one self-hostable platform — an MCP firewall that defines allow, deny and require-approval rules on tool access; an AI model gateway that attributes cost and enforces per-agent budgets; policy-as-code written in YAML with CEL expressions; human-in-the-loop approvals delivered to mobile, watch, Slack, Mattermost or a webhook; runtime session observability; and an audit trail. Onboarding is deliberately frictionless: `preloop agents discover` finds compatible agent configurations already on the machine and transparently rewrites them so tool calls route through the MCP firewall and model traffic through the gateway, with no SDK changes and no agent code changes. The named runtimes it rewrites include Claude Code, Codex CLI, Cursor, Gemini CLI, Hermes, OpenClaw, OpenCode and Windsurf. The vendor positions Preloop explicitly as an open-source alternative to AWS Bedrock AgentCore and as a way to build EU AI Act readiness evidence, with dedicated guidance published for that use case. Because the full control plane is Apache 2.0 and self-hostable, the paid tiers sell hosting, team governance and conditional-approval sophistication rather than the core capability.
Ideal use cases:
- •Teams or individuals who need mcp firewall with allow, deny and require-approval rules on tool access
- •Teams or individuals who need ai model gateway with per-agent budgets and cost attribution
- •Teams or individuals who need policy-as-code in yaml with cel expressions
- •Teams or individuals who need human approvals on mobile, watch, slack, mattermost or webhook
- •Anyone focused on mcp workflows
- •Anyone focused on agent-governance workflows
Best for: Weavz
Weavz is agent integration infrastructure that sits between AI agents and the business apps a company already runs. Instead of handing each agent its own OAuth tokens and API keys, you provision a scoped workspace per customer, team, project or agent, mount the apps you want as stable aliases, generate hosted connect links so end users authorise their own accounts, and then issue the agent a scoped MCP endpoint. The catalog covers more than 1,000 apps and roughly 12,000 agent tools — Gmail, Slack, HubSpot, Salesforce, Notion, Sheets, GitHub, Linear, Stripe, Zendesk and the rest — and the same workspace works from Claude, ChatGPT, Codex, Claude Code, Cursor, VS Code, Cline, Gemini CLI, OpenCode or any custom remote MCP client. What separates it from a plain connector directory is the governance layer: Human Gates apply approval policies to actions taken through REST, SDK, MCP, the playground or triggers; Input Partials pre-fill or lock argument values before an agent ever sees them; and every action lands in an audit trail. The platform also ships sandbox execution runtime, browser control, a filesystem and a state key-value store as first-class primitives rather than separate add-on packages, so a single plan covers the whole surface and the tiers differ only by capacity.
Ideal use cases:
- •Teams or individuals who need 1,000+ app integrations, 12,000+ agent tools
- •Teams or individuals who need per-customer scoped workspaces and mcp endpoints
- •Teams or individuals who need human gates approval policies
- •Teams or individuals who need input partials for locked or pre-filled arguments
- •Anyone focused on mcp workflows
- •Anyone focused on integrations workflows
