Agent Registry vs MCP Marketplace vs AgentHub Enterprise

Overview

Three agent marketplaces launched within the same 10-day window in late September 2026, each targeting a different slice of what used to be a single, undefined "agent marketplace" category. Choosing the right one depends on what you're actually selling — agent capabilities as tools (MCP Marketplace), agents as standalone SKUs (AgentRegistry), or enterprise procurement with compliance (AgentHub Enterprise).

This comparison breaks down the trade-offs between the three and helps you pick the right distribution channel for your agent.

AgentRegistry

Best for: authors who have built a production agent and want to monetize it without building billing plumbing.

AgentRegistry is designed for people who have a working agent — a code reviewer, a research assistant, a workflow automation — and want to charge for it. The registry handles billing, identity, versioning, and distribution. It sits above the MCP layer: your agent is the product, and the MCP card is a side-effect of listing it.

Strengths:

• Built-in billing with revenue splits
• Persistent agent identity with reputation
• Curated gate keeps the catalog clean
• Multi-provider backends mean no vendor lock-in

Weaknesses:

• 15% cut is higher than most app-store equivalents
• Curation creates latency for new authors
• Smaller catalog than MCP Marketplace
• No native debugging surface

MCP Marketplace

Best for: authors who built an MCP server and want maximum discoverability.

MCP Marketplace is the de-facto listing for anything MCP. Its catalog is enormous (~10,000 servers), and its discovery surfaces are widely used. But it's a tool catalog, not an agent catalog — you list MCP servers, not packaged agents. If your product is genuinely an MCP server (a database adapter, a search index, a file sync layer), this is where you belong.

Strengths:

• Largest catalog by far
• Standard listing format across all MCP clients
• No curation gate — submit and go live
• Community-driven discovery

Weaknesses:

• Not designed for agents; agents are too complex for the MCP card format
• No built-in billing — you have to handle payments yourself
• No reputation or versioning system
• Discovery is high-noise; standing out requires marketing

AgentHub Enterprise

Best for: teams selling agents to regulated or enterprise buyers who need compliance guarantees.

AgentHub Enterprise is the B2B version of AgentRegistry, with SOC 2 reporting, enterprise SSO, and per-agent audit logs. It's designed for buyers at financial institutions, healthcare providers, and government contractors — buyers who cannot deploy an agent without a compliance story. The catalog is smaller but the average deal size is significantly larger.

Strengths:

• SOC 2, ISO 27001, and HIPAA alignment
• Enterprise SSO and audit logs
• Custom deployment options (private, on-prem)
• Sales motion includes a procurement-ready contract template

Weaknesses:

• Custom pricing, not self-serve
• Long sales cycle (typical 3-6 months)
• Not designed for solo developers or small teams
• No self-serve signup

Decision Guide

Pick AgentRegistry if:

• You have a working agent and want to charge for it
• You want self-serve distribution without building billing
• You're OK with a 15% revenue cut and curation review

Pick MCP Marketplace if:

• You built an MCP server, not an agent
• You want maximum discoverability across MCP clients
• You can handle billing yourself
• You don't need a persistent identity

Pick AgentHub Enterprise if:

• You're selling to regulated or enterprise buyers
• Compliance is a requirement, not a nice-to-have
• You can invest in a longer sales cycle
• Your agent has a meaningful enterprise value proposition

Pick multiple if:

• Your agent can be packaged both as an MCP card (MCP Marketplace) and as a standalone agent (AgentRegistry)
• You target both consumer and enterprise (AgentRegistry for mid-market, AgentHub Enterprise for regulated buyers)

Migration Path

The natural progression for many agent authors is:

1. Start at MCP Marketplace — get distribution for the MCP surface of your agent
2. Move to AgentRegistry — when you have a packaged agent with a revenue model
3. Graduate to AgentHub Enterprise — when you get your first enterprise sale requiring compliance

Each step adds billing complexity and compliance overhead, but also opens higher-value distribution. The right step depends on where your buyers are today, not where the industry is heading.
