Standard

Why use Ceven?

  1. AI native Manus integration

    • Describe the outcome and Ceven picks the right Manus calls, fills the parameters, and checks the result.
    • Structured, agent friendly tool schemas so each call runs reliably instead of by guesswork.
    • Rich coverage for reading, writing, and querying your Manus data, across all 14 of its actions.

  2. Managed auth

    • Built in OAuth with automatic token refresh and rotation.
    • One place to manage, scope, and revoke Manus access.
    • Per user and per environment credentials instead of shared keys.

  3. Agent optimized design

    • Actions are tuned from real success and error rates so reliability climbs over time.
    • Full execution logs so you always know what ran in Manus, when, and on whose behalf.
    • The agent pauses and asks when Manus is unclear instead of plowing ahead.

  4. Enterprise grade security

    • Fine grained access so you control which agents and people can reach Manus.
    • Least privilege by default, read scopes first and only the writes a workflow needs.
    • A full audit trail of every Manus action to support review and sign off.

Supported tools

Every action Ceven's agents can run on Manus, and when to use it.

Create file
Use this to get a presigned URL for uploading file content to S3 for AI processing.
Create new project
Use this to organize related tasks and apply consistent instructions across a project ID.
Create new task
Start a new AI task with custom parameters and attachments or continue a multi turn conversation.
Create webhook
Register a webhook to receive real time notifications for task created or task stopped events.
Delete file
Remove a file record and its associated S3 storage by ID.
Delete task
Permanently remove a specific task from the system by its ID.
Delete webhook
Remove an existing webhook subscription that is no longer needed.
Get file details
Pull metadata and status for a specific file to check if it is pending or uploaded.
Get task
Pull the current status, output messages, and credit usage for a specific task ID.
Get webhook public key
Retrieve the RSA public key to verify that webhook signatures genuinely came from Manus.
List uploaded files
Pull a list of the ten most recently uploaded files with their IDs and timestamps.
List projects
Retrieve all projects in the account to find a specific project ID.
List tasks
Fetch multiple tasks using filters for status or sorting by creation time.
Update task
Modify task metadata like the title or change public sharing and visibility settings.
Delete a file
Deletes a file by ID. This removes both the file record and the file from S3 storage. Use when you need to remove a previously uploaded file from the Manus platform.

Frequently asked questions

Ceven follows a two step process to ensure files are handled securely and efficiently. First, the agent calls the Create File action to request a presigned URL from the Manus API. This URL points directly to an S3 bucket. Ceven then performs a PUT request to upload the file content directly to that location. This method prevents large files from clogging the API gateway and ensures that the AI has direct access to the data. Once the upload is complete, Ceven verifies the file status using the Get File Details action before attaching that file ID to any new AI tasks you trigger.
Yes, Ceven uses Manus webhooks to avoid constant polling. When you set up a workflow, Ceven creates a webhook registration that tells Manus to push updates to our listener whenever a task changes state, such as moving from pending to progress or completed. This allows your workflow to trigger the next step, like sending a Slack notification or updating a database, the millisecond the AI finishes its work. If you prefer a manual check, the agent can also use the Get Task action to pull the latest output messages and credit usage for a specific task.
Manus enforces strict rate limits on task creation based on your account tier. If a Ceven workflow attempts to spin up dozens of tasks simultaneously, you may encounter a 429 Too Many Requests error. To handle this, Ceven implements an exponential backoff strategy, queuing requests and retrying them at intervals. Users on lower tiers should be aware that concurrent task limits are tighter, so we recommend batching tasks within a single project or spacing out triggers in your workflow to avoid hitting these API ceilings during peak operational hours.
Projects act as a container and an instruction set for tasks. When Ceven creates a new project, it sets a baseline of context and rules that every task within that project inherits. This is critical for maintaining consistency across a large volume of AI work. For example, if you have a project for competitive intelligence, the project level instructions ensure every task uses the same formatting and source requirements. Tasks are the individual units of work. By using the project ID when creating tasks, Ceven ensures the AI does not have to be re briefed on the overall goal every time.
No, the Delete Task action is permanently destructive. Once Ceven sends the request to remove a task by its ID, Manus wipes the task record and all associated output messages from its active database. There is no trash bin or undo feature available through the API. We strongly recommend configuring your Ceven workflows to archive the output messages to a secondary system, like Notion or a SQL database, using the Get Task action before triggering a delete command to ensure you have a permanent record of the AI work.
Security is handled through RSA signature verification. Ceven uses the Get Webhook Public Key action to retrieve the current public key from Manus. Every time Manus sends a webhook notification to Ceven, it includes a cryptographic signature in the header. Ceven uses the stored public key to validate this signature, ensuring that the request actually came from Manus and not a malicious third party. This prevents attackers from spoofing task completion events to trigger downstream actions in your business tools, like sending an unauthorized email to a client.
Yes, the Create New Task action supports continuity. When the agent starts a task, Manus returns a unique task ID. To continue the conversation or provide follow up instructions based on the AI output, Ceven passes that same task ID back into the next request. This tells Manus to maintain the conversation state and memory from the previous turns. This is particularly useful for iterative research where the first task identifies a list of companies and the second task dives deeper into a specific one based on the results of the first.
If the initial request for a presigned URL fails or the subsequent PUT request to S3 returns an error, Ceven marks that specific step as failed and triggers your defined error path. Because file uploads are decoupled from task creation, the agent can attempt to re upload the file up to three times before alerting the user. If the failure is due to a file size limit imposed by Manus, the agent will capture the specific error message and notify you that the file exceeds the platform maximum, allowing you to compress the document and restart the workflow.
