Build Manus AI Worker

This builder's guide provides detailed instructions for building AI Worker with Manus core agent. Manus is a general-purpose autonomous AI agent that can plan, execute, and complete multi-step tasks end-to-end.

TL;DR »

When using Manus as a core agent, it acts as a reasoning and execution engine for the AI worker, while Humatron provides the orchestration, infrastructure and services for the AI worker.

To integrate Manus with Humatron, you need:

Create new build
Select Manus as the core agent
In Manus - create new custom MCP connector with Humatron MCP
Pass newly created connector UUID to Humatron build
Set Manus API key to Humatron build
Configure additional MCP, functions, VPS scripts, etc.
Submit new build
Hire the AI Worker using the new build 🚀

End-To-End Message Flow »

When user interacts with the Manus-based AI worker, the message flow is as follows:

User (request)Humatron
Humatron Manus Task
Manus tasks produces response
Manus calls Humatron MCP Connector
Humatron User (response)

A Manus response is only "delivered" if it goes through Humatron MCP. Replies inside Manus alone are invisible to the user. If this end-to-end loop is not closed, the AI worker is effectively silent.

One Build - Many Hires »

A Humatron build acts as a shared template for AI workers of a certain type. It defines the Manus agent configuration, custom tools, and MCP servers that are inherited by all hires of that build. When a hire is created, the build is instantiated into a unique hire instance, which is then customized further based on the employer's context and the specific job requirements.

Common build settings that are shared across all hires of the same build include:

Manus agent configuration
Role and role's instructions
Deployment configuration
Custom tools and MCP servers

Each build can be used to create multiple AI workers. When you create a build, it automatically generates a resumé - the public-facing representation of that build. Note that access to the build and its resumé is governed by the build's publishing status.

Depending on publishing status, the build will be visible either to you only, to your company or to the general public. Among other parameters, the resumé displays essential information from the build such as professional summary, role description, and the list of skills.

During hiring, users select the build (via its resumé) and fill out the hiring form to create a new AI worker from that build. When fully deployed and instantiated, this newly created AI worker becomes an independent instance of that build that is customized with:

Personalized name and avatar
Social preferences
Communication style
Job-specific instructions and requirements
Docker environment variables
Shell scripts to run before and after the deployment
Knowledge base data sources

Combination of separate builds and hires defines Humatron's «One Build - Many Hires» architecture, where every AI worker functionally consists of two layers:

Build - common configuration and shared agentic capabilities
Hire - employer-specific, individual and job-related customizations

This two-stage approach allows you to concentrate most of the capabilities in a shared build ensuring functional consistency across workers - while at the same time allowing for individual customization to meet specific employer's needs.

Step 1: Create new build »

Start a new build. Every new build at Humatron starts with the following properties:

Role

A role typically defines a job title, position or level of responsibility within a company or organization. It typically reflects the nature of the job, the industry, and sometimes the hierarchy within the workplace. Examples of roles:

Legal Assistant
Accountant
Document Translator
Python Coder

Avatar

Ensure that the build avatar matches the build's job role. Note that selecting a human image or a photograph for your AI worker build does not conceal their AI nature. Note also that if the social customization is allowed the avatar can be changed during the hiring process along with name, gender and communication style.

NOTE:
Avatar image must be a square of at least 96px size or larger. 512px size or larger if using Slack. 2 MB maximum file size.

Role Instructions

Role instructions acts as an LLM system prompt and provide an initial detailed operating handbook, e.g. employee handbook, for the main functional responsibilities of this AI worker. Each functional job area should be described in sufficient detail - in the same way as it would be described to a junior level human employee. These instructions will be integrated into the overall context for Manus agent and should be modelled similar to a well organized reasoning prompt.

Note that an AI worker will learn new skills and adapt existing skills and internal instructions over time. All AI workers come with a set of built-in core skills and capabilities that are specific to the Manus agent. You do not need to instruct about any of these. Do not include function or MCP server definitions here.

You can also attach any files that would help to augment or define additional general context about role instructions. These may include operating guidelines, technical specifications, etc.

Step 2: Configure Manus Integration »

If necessary, create new Manus project on Manus side. Select "Manus" as the core agent on build form - that will open Manus configuration form:

Enter Manus API key.
- Settings ⇢ Integrations ⇢ Build With Manus API
Select Manus Agent Profile from the dropdown.
Enter optional Manus Project ID.
Add provided instructions to your Manus global or project settings.
Add provided Manus MCP connector "humatron-agent-mcp" as custom MCP connector. This MCP connector exposes Humatron functionality to Manus agent allowing it to use built-in Humatron capabilities and access Humatron data.
Enter a comma-separated list of UUIDs of all custom MCP connectors that you want to use for this build. Note that this list should contain at least UUID of the newly added MCP connector "humatron-agent-mcp" as well as UUIDs of all other custom MCP connectors added on the Manus side that you want to use for this build. If custom MCP connector UUID is not listed here, it will not be available to the Manus-based AI worker.

Step 3: Configure Function `&` MCP Servers »

You can optionally add REST functions and MCP servers to your build - the additional, custom set of tools that Manus agent will have access to. REST functions allow you to expose your own internal or external APIs to the Manus agent. MCP servers are more powerful than REST functions and allow you to expose more complex APIs to the Manus agent in a standardized way. These tools will be deployed for each new hire on the hire-side either on a VPS instance or on on-prem deployment.

With Manus agent - there are four sets of tools that Manus agent has access to:

Manus built-in tools
MCP connectors you add to your Manus project
"humatron-agent-mcp" MCP server (part of Manus agent integration) that exposes Humatron functionality to Manus agent
Custom tools added and deployed on the Humatron side (build form settings)

Make sure that there are no functional conflicts or duplicates between the four sets of tools. Also ensure that there is no technical interference between different sets of tools. We recommend starting with a minimal number of custom tools and developing and testing tools in isolation outside of Humatron platform since it is not designed as a full-featured development environment.

Start Small & Increment
Ensuring conflict-free operation between multiple sets of tools is not trivial. Start with a minimal number of custom tools that you do not expect to conflict with each other. Add custom tools gradually and use agent evaluations to test. Develop and test them in isolation.

Step 4: Additional Configuration »

Each build includes a set of additional configuration options and settings. These are optional, as they are either read-only or preconfigured with sensible defaults.

Restrict Social
You can protect your distinct brand identity (personal or corporate) by restricting modifications to social attributes such as name, gender, avatar, and communication style during the hiring process. When such modifications are disabled, all AI workers built from your build will use name, gender, avatar and communication style of this build maintaining consistent social attributes of your brand.
Important considerations:
- This feature prevents multiple hires of the same build by a single employer, as it would create duplicate identities.
- If you choose to restrict social attribute modifications, you must provide default values for these properties in your build configuration.
Initial Shell Scripts
Each hired AI worker is deployed either on-prem or on cloud (AWS, Azure, or OpenStack) on its own VPS instance. You can attach shell scripts to run before and after the build's MCPs are installed, enabling fine-tuned configuration of the hire instance runtime environment during startup and restarts. For example, you might use these init scripts to install additional libraries or Docker containers at startup to support custom telemetry, logging, or other extensions for your build.
Deployment
Humatron supports both on-prem and cloud-based deployments with full isolation of the infrastructure and data. On-prem deployment allows for full control of the infrastructure and data, while cloud-based deployment allows for easy scalability and deployment and management. Each AI worker is deployed either on-prem or on cloud (AWS, Azure, or OpenStack) on its own VPS instance. If you are deploying using cloud-based VPS, choose an instance that matches your CPU and RAM needs; all workers run on Ubuntu 24.04 LTS by default. Keep in mind that added MCP servers are the primary factor influencing how much CPU and memory capacity your VPS instance should provide.
Support Email
A support email is required and will be publicly displayed on the resumé as the primary support contact. Additionally, you may provide an optional link to external documentation or a detailed description of the AI worker's capabilities, skills, and functionality. This link will also be shown on the resumé.
Build Token
Each build is issued a unique build token, generated once at creation. Together with the corresponding organization and hire tokens, it can be used for MCP or tool authorization and authentication.

Step 5: Submit `&` Hire 🚀 »

Once build form is completed - submit it. Note that you can update and reconfigure the build any time later. After submission, you can hire the AI worker right away using the new Manus-based build.

When build is submitted for the first time - the resumé for this build is automatically generated.

Resumé is generated based on the build instructions and is visible to the public.
You can update resumé overview and skills list at any time.

Changes to the build may require a restart of the AI worker to take effect:

Some changes, like overview and skills list, do not require a restart of the AI worker to take effect.
However, it is recommended to assume that other changes to the build will be applied to the new AI workers only.
When build is public (published on the marketplace) - there is no way to force a restart of the existing AI workers of this build.
Any changes to the public build configuration will apply to new AI workers only.

Build can only be deleted after all AI workers of this build are terminated, if any. You can change publishing status of the build to builder to prevent new AI workers from being created.

Note:
Even if the build has no AI workers created off it yet - it will still incur some (minimal) credit consumption.

Build Lifecycle »

Build goes through the following lifecycle stages:

Live
When build is first submitted - it is automatically in live status. This is the normal status for the build when all permitted operations on the build are available.
Paused
The owner of the build can pause the build at any time. When build is paused - it is not available for hiring. Note, however, that the build is still subject to normal credit consumption. When build is paused - the existing AI workers of this build are NOT paused. The build owner can resume the build for hiring at any time. When build is resumed - it goes back to live status.
Suspended
Unlike pausing the build which can only be done by the build owner - the suspension of the build can only be performed by Humatron team. It happens when Humatron team determines that the build is in violation of the platform policies. When build is suspended - it is not available for hiring and will be further reviewed by Humatron team. Only Humatron team can reinstate the build to live status. If your build is suspended - contact Humatron support team at support@humatron.ai for more details.
Removed
Build can be removed only by the build owner. When removed it is no longer available for hiring or further modification. Removed build cannot be reinstated. Removed builds are available on the dashboard for informational purpose only. Only when the build is removed - all billing and credit consumption associated with this build are stopped.

Build Publishing »

When build is first created - it is in builder publishing mode. This is the mode where only the builder (the user that created the build) can hire the build. Build can be published between different modes where each mode has different visibility and cost profile:

Build Mode	Who Can Hire	Use Case	Cost Margins	Commission on Hire
`Builder`	Builder only	Development, testing, prototyping	Low	None
`Private`	Builder's company	Internal AI workers for company use	High	None
`Public`	Anyone	Marketplace - builder sets the price per hire	Medium	20% per hire (80% paid to builder)

Build Pricing »

Build pricing is generally designed to be directly aligned with actual system usage.

Under the hood, the platform orchestrates multiple third-party and internal services - LLM providers, compute/hosting, storage, agents, messaging, and more. Each operation incurs a real cost. Humatron applies a small, consistent margin on top of these underlying costs and deducts the total from your credit balance.

Some charges are applied per operation (e.g., model inference), while others are amortized over time (e.g., infrastructure and shared platform services). You can monitor overall and individual credit consumption for each hire and build.

Credit consumption depends on the core agent. For example, with Blackbox agent, Humatron manages and bills for model inference via its own LLM integrations. With agents like OpenClaw, the builder provides and pays for the model directly, so inference costs are not charged to Humatron credits in this case.

Pricing further depends on the publishing mode of the build. In builder publishing mode, margins are minimized to reduce iteration cost during development. In private mode (company use), margins are higher to reflect production-grade reliability and support, while remaining commission-free. In public mode (marketplace), medium margins apply - covering production-grade reliability and scalability, yet accounting for the 20% per-hire Humatron commission.

Observability, Governance, Guardrails »

Humatron provides a comprehensive set of internal and external observability, governance, and guardrails tools to help you manage your builds and AI workers.

Audit

Every AI worker instance deployed on Humatron platform comes with built-in internal audit functionality. Click on 'Edit' button next to the AI worker instance (hire) and on 'Edit Hire' form you will see 'Audit' button.

Dozzle

Dozzle provides real-time logging and monitoring of the AI worker instance in its Docker containers. Every live AI worker instance (hire) comes with built-in Dozzle monitoring functionality. On a live hire instance you will see 'Dozzle' button that opens built-in Dozzle monitoring dashboard. You can find Dozzle & SSH passwords and usernames in the same 'Edit Hire' form.

PortKey

PortKey provides a comprehensive set of observability, governance, and guardrails tools to help you manage your AI workers. You can configure PortKey API key and optional configuration ID on 'Organization Edit' form. Once configured, you can see 'PortKey' button on hire and built edit forms that will navigate to the PortKey dashboard.
