Blocks.ai vs MuleSoft Agent Fabric
Blocks.ai
Network for AI agents: a free public network, and a private network for each company
MuleSoft Agent Fabric
Control plane for agents, MCP servers, and APIs across platforms
Short answer
MuleSoft documents Agent Fabric as an AI control plane: it registers agents from supported platforms with scanners, enforces policy through a gateway in the request path, and orchestrates A2A-compliant agents.Source 1, Source 2 Blocks.ai connects AI agents where they already run, with no inbound ports, and lets you decide who can reach each one, including other companies.Source 3, Source 4, Source 5

- Agents across organizations: Not publicly documented
At a glance
What each one is
Blocks.ai
Blocks.ai is a network: a free public network, and a private network for each company.Source 8, Source 16 A company’s private network gives it one place to connect, govern, and audit its agents, whoever built them and wherever they run.Source 8 Blocks.ai does not build, host, or orchestrate agents.Source 3, Source 6
MuleSoft Agent Fabric
MuleSoft Agent Fabric is an AI control plane for agents, MCP servers, and APIs across platforms.Source 1 MuleSoft says it discovers, governs, orchestrates, and observes agents, combining enhancements to existing MuleSoft products with new capabilities.Source 21 MuleSoft says it is generally available.Source 14
The differences that matter
Agents at other companies
Blocks.aiOn the Pro tier, a partner company joins your private network as its own organization.Source 15, Source 16 You can call only the agents it shares with you.Source 9, Source 17
MuleSoft Agent FabricAgent networks can use agents from another network or elsewhere in your company.Source 18 Their egress gateway enforces policy on calls to agents outside the network.Source 19
For Agent Fabric, partner-held access controls are not publicly documented. On Blocks.ai, your administrators can see a partner’s registered agents and, on the Pro tier, take one offline.Source 9, Source 17
How agents connect
Blocks.aiEvery Blocks.ai agent connects out over HTTPS on port 443, and its host needs no inbound ports, DNS records, or static IP.Source 4
MuleSoft Agent FabricOmni Gateway sits in the request path of each managed agent, API, or MCP server, and enforces policy there.Source 2
A self-managed Omni Gateway can run in your own private cloud or data center.Source 22 An outbound-only way for an agent to join Agent Fabric is not publicly documented.
How agents get into the registry
Blocks.aiEach agent connects through the Blocks.ai SDK and is registered with the CLI, whatever its framework, model, or cloud.Source 5, Source 6, Source 10, Source 11
MuleSoft Agent FabricScanners automatically register agents, APIs, and MCP servers on supported platforms.Source 2 Agents they miss can be registered manually by uploading an agent card.Source 12, Source 14
Agent Fabric’s scanners run at most once a day.Source 23 Blocks.ai does not publicly document a way to find agents that haven’t connected.
