LangSmith vs MuleSoft Agent Fabric

LangSmith

Platform for observing, evaluating, and deploying agents

MuleSoft Agent Fabric

Control plane for agents, MCP servers, and APIs across platforms

Short answer

LangChain calls LangSmith a platform for observing, evaluating, and deploying agents, while MuleSoft Agent Fabric is a control plane for agents, MCP servers, and APIs across platforms.⁠Source 1, Source 2 LangSmith builds, runs, and traces agents; Agent Fabric registers agents found on supported platforms and enforces policy at a gateway in the request path of managed agents.⁠Source 3, Source 4, Source 5, Source 6

Where each one sits

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

These aren’t the same kind of product

Where they overlap
Both keep a registry of agents (LangSmith’s for agents on Deployment), can authenticate calls to agents, support MCP and A2A, and keep audit logs, LangSmith’s on its Enterprise plan.⁠Source 6, Source 7, Source 8, Source 9, Source 10, Source 11, Source 12, Source 13
Where they differ
In LangSmith, teams build agents in Fleet and run agents on Deployment.⁠Source 3, Source 4 Agent Fabric’s scanners register agents found on supported platforms, and its brokers orchestrate A2A-compliant agents.⁠Source 6, Source 14
Running both
MuleSoft documents an Exchange scanner that discovers, imports, and syncs agents from LangSmith, so they can be governed.⁠Source 15

What each one is

LangSmith

LangChain describes LangSmith as a framework-agnostic platform for observing, evaluating, and deploying agents.⁠Source 1 LangSmith Deployment runs agents in production on Agent Servers, and LangChain says Fleet lets teams, including non-technical ones, create and manage agents without code.⁠Source 1, Source 3, Source 4, Source 5 Agents hosted elsewhere can send it traces.⁠Source 20

MuleSoft Agent Fabric

MuleSoft documents Agent Fabric as a control plane for agents, MCP servers, and APIs across platforms.⁠Source 2 Scanners and manual registration fill its registry, Omni Gateway enforces policy in the request path of managed agents, and agent brokers orchestrate A2A-compliant agents.⁠Source 6, Source 21

The differences that matter

  1. Building and running agents

    LangSmith

    Fleet builds agents without code, from a description or template, and LangSmith Deployment runs agents in production.⁠Source 3, Source 4

    MuleSoft Agent Fabric

    Agent Fabric’s brokers, written in Agent Script, orchestrate A2A-compliant agents; MuleSoft says Salesforce’s separate Agentforce is for building agents within Salesforce.⁠Source 6, Source 14, Source 19

  2. Agents from other platforms

    LangSmith

    Deployment runs agents built with Google ADK, CrewAI, and other frameworks.⁠Source 18 Agents hosted elsewhere can send traces.⁠Source 20 Registering those agents is not publicly documented.

    MuleSoft Agent Fabric

    Scanners register agents, APIs, and MCP servers they find on supported platforms; agents they miss can be registered by uploading an agent card.⁠Source 6, Source 19, Source 21

    LangSmith accepts traces from any OpenTelemetry-compatible application.⁠Source 30 Agent Fabric’s scanners run at most once a day.⁠Source 31

  3. Where access is controlled

    LangSmith

    Hosted Agent Servers check LangSmith API keys by default, or auth handlers you write; Fleet has per-agent Clone, Run, and Edit permissions.⁠Source 8, Source 16

    MuleSoft Agent Fabric

    Omni Gateway sits in the request path of each managed agent, API, or MCP server; governance strategies define rules once across those in scope.⁠Source 6

    Fleet agents can be set to pause for approval before specific actions.⁠Source 32 Agent Fabric can quarantine a flagged agent after an admin reviews it.⁠Source 33

For security teams

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

TopicLangSmithMuleSoft Agent Fabric
Network exposureOn self-hosted LangSmith with Deployment, agents run behind an ingress you configure.⁠Source 34 Enterprise can reach LangSmith Cloud privately.⁠Source 22Omni Gateway sits in managed agents’ request path; agent-network ingress gateways get a public endpoint, egress gateways none.⁠Source 6, Source 35
IdentityHosted Agent Servers default to API keys; self-hosted ones have no default authentication.⁠Source 8 Cloud Enterprise adds SAML SSO and SCIM.⁠Source 36Agents set up as service identities in your IdP for rogue-agent detection; Omni Gateway supports OAuth 2.0 token exchange.⁠Source 33, Source 37
Access changes and revocationFleet sharing can be revoked at any time, and organization admins can deactivate any member’s personal access token.⁠Source 32, Source 38After review, quarantine stops a flagged agent from acting and blocks it at model proxies with the Kill Switch policy.⁠Source 33
Audit trailEnterprise audit logs of admin and configuration actions, kept up to 400 days, can be pulled hourly into a SIEM.⁠Source 11Omni Gateway can keep a traffic audit trail; Anypoint Platform audit logs are kept one year by default.⁠Source 6, Source 13
ComplianceLangChain lists SOC 2 Type II, ISO 27001:2022, GDPR, and HIPAA for LangSmith.⁠Source 39, Source 40MuleSoft says Anypoint Platform meets ISO 27001, SOC 2, PCI DSS, and HIPAA.⁠Source 41 Agent Fabric’s own scope: not publicly documented.

Which to choose

Choose LangSmith if

  • Non-technical teams should build agents without code, from a description or template, and use them in Slack, Teams, or Gmail.⁠Source 1, Source 3, Source 56
  • You want a managed runtime for code-first agents built with LangGraph, Google ADK, CrewAI, or other frameworks.⁠Source 4, Source 18
  • You need LangSmith’s control plane and Agent Servers in your own infrastructure, for full data residency or air-gapped use, on Enterprise.⁠Source 4
  • You want to trace agents wherever they run, from any OpenTelemetry-compatible app or through integrations such as OpenAI, Anthropic, and CrewAI.⁠Source 20, Source 30, Source 57

Choose MuleSoft Agent Fabric if

  • Your agents already run on several platforms, and you want scanners that MuleSoft says cover Amazon, Google, Microsoft, and more.⁠Source 6, Source 42
  • You want policy enforced at a gateway in managed agents’ request path, where MuleSoft says third-party agents can be governed unmodified.⁠Source 6, Source 19
  • You already use MuleSoft’s Anypoint Platform and want one control plane, built on it, for agents, MCP servers, and APIs.⁠Source 2, Source 42
  • You want brokers to orchestrate A2A-compliant agents across ecosystems, and to quarantine a flagged agent after an admin reviews it.⁠Source 6, Source 14, Source 33

Questions buyers ask
