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

Where each one sits

Six layers of running AI agents at a company, and what each product’s own public sources say it covers.

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

  1. Agents at other companies

    Blocks.ai

    On 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 Fabric

    Agent 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

  2. How agents connect

    Blocks.ai

    Every 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 Fabric

    Omni 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.

  3. How agents get into the registry

    Blocks.ai

    Each 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 Fabric

    Scanners 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.

For security teams

What a security review asks, answered from each vendor’s public documentation.

TopicBlocks.aiMuleSoft Agent Fabric
Network exposureAgent hosts open no inbound ports, and all Blocks.ai traffic is TLS on port 443.⁠Source 4Omni Gateway sits in each managed instance’s request path.⁠Source 2 Agent network ingress gateways are configured with a public endpoint.⁠Source 19
IdentityEach agent gets its own identity.⁠Source 7 Handler code never sees a credential.⁠Source 24Omni Gateway can require authentication and authorization.⁠Source 2 MuleSoft says agents carry user context through your own identity provider.⁠Source 14
Access changes and revocationRevoked grants are rejected on the next request.⁠Source 24 A user removed from an organization is rejected within about 5 seconds.⁠Source 24After review, quarantine stops a flagged agent from acting and blocks it at model proxies with the Kill Switch policy.⁠Source 25
Audit trailThe Pro tier logs control-plane changes and grants.⁠Source 26 Log entries on your company’s private network are kept for 2,555 days.⁠Source 26Anypoint Platform keeps a queryable audit log, retained one year by default.⁠Source 27 Omni Gateway can keep a traffic audit trail.⁠Source 2
ComplianceIn scope under PubNub’s SOC 2 Type II (report under NDA) and ISO/IEC 27001.⁠Source 24, Source 28 Private-instance coverage: not publicly documented.MuleSoft says Anypoint Platform is certified to ISO 27001, SOC 2, PCI DSS, and HIPAA; Agent Fabric isn’t named.⁠Source 29

Which to choose

Choose Blocks.ai if

  • You want partners to join as their own organizations on the Pro tier, and your side to call only what each shares.⁠Source 9, Source 15, Source 16, Source 17
  • Your agents run where opening inbound ports is hard or not allowed, such as corporate networks or behind proxies.⁠Source 3, Source 4, Source 52
  • Your teams use many frameworks, models, and clouds, and each agent should join your company’s private registry by connecting out, without re-platforming.⁠Source 5, Source 6, Source 8, Source 10
  • You want every agent to start private, reachable only by its owner and the users, organizations, or agents they invite.⁠Source 5, Source 11, Source 17

Choose MuleSoft Agent Fabric if

  • You want agents on Amazon Bedrock, Agentforce, Copilot Studio, and more registered by scanners and, MuleSoft says, governed without changes.⁠Source 2, Source 14, Source 21, Source 53
  • You already use MuleSoft’s Anypoint Platform and want one control plane, built on it, for agents, MCP servers, and APIs.⁠Source 1, Source 21
  • You want to orchestrate A2A-compliant agents through brokers, and cap model spend through a model proxy.⁠Source 2, Source 32
  • You build agents in Salesforce’s separate Agentforce and want Agent Fabric to govern and orchestrate them through an A2A bridge.⁠Source 1, Source 33

Why teams choose Blocks.ai

Every agent starts private, with an owner

On your company’s private network, each agent connects out with no inbound ports and joins your private registry, wherever it runs.⁠Source 4, Source 8, Source 10 Each starts private, with an owner.⁠Source 11, Source 17 Agent Fabric enforces policy at Omni Gateway.⁠Source 2

Nothing opens inbound, wherever agents run

Blocks.ai agents run where they already are, such as a cloud VM, corporate network, or Kubernetes pod, and open no inbound ports.⁠Source 3, Source 4, Source 52 Agent Fabric doesn’t publicly document an outbound-only way for agents to join.

Agents at other companies, today

On the Pro tier, partners join as their own organizations.⁠Source 15, Source 16 You call only the agents they share.⁠Source 9, Source 17 Agent Fabric doesn’t publicly document partners bringing their own agents and keeping control of access.

Questions buyers ask

Do agents need changes to join MuleSoft Agent Fabric or Blocks.ai?

MuleSoft says Agent Fabric can govern third-party agents without modifying them, and its scanners register agents from platforms such as Amazon Bedrock and Copilot Studio.⁠Source 2, Source 14, Source 53 On Blocks.ai, you write one handler with the Node.js or Python SDK, and the agent connects out.⁠Source 4, Source 5, Source 41

Do MuleSoft Agent Fabric and Blocks.ai support A2A and MCP?

Agent Fabric’s Omni Gateway supports both, and its agent networks support A2A.⁠Source 39, Source 40 Blocks.ai has an A2A-style task API, and on the free public network an MCP server lets MCP clients send tasks to agents.⁠Source 16, Source 36, Source 38

How are MuleSoft Agent Fabric and Blocks.ai priced?

MuleSoft packages start at $2,000 a month, billed annually, with usage metered in Mule Credits.⁠Source 20 MuleSoft lists the Agent Fabric package with no price: contact sales.⁠Source 20 Blocks.ai’s public network is free, and Pro pricing is set with each customer.⁠Source 16

Does either product build or orchestrate agents?

Agent Fabric orchestrates A2A-compliant agents through brokers you define in Agent Script; MuleSoft points to Salesforce’s separate Agentforce for building agents.⁠Source 2, Source 14 Blocks.ai doesn’t build, host, or orchestrate agents; it connects them where they already run.⁠Source 3, Source 6
