E2B connector reference

Operations, inputs, troubleshooting, and questions for the E2B connection. Policy decides each change before the credential is resolved, and the action record carries the result.

Set up and verify the E2B connection

Choose one task and its account, and match the reads and actions on the overview page to it before granting provider permissions.
Prepare the connection settings from the overview page, connect the provider in Deixic, and choose which tools your agent can use.
Try a small task with a known result, and compare the returned identity and resource with what the account owner expects.
Configure approval for sensitive changes, review the destination and inputs, and check the result in the provider before expanding the workflow.

Information your agent can use

Resource	Record identity	Start with	Page coverage
Volumes	`volumeID`	Top level	None configured
Sandboxes	`sandboxID`	Top level	None configured
Sandbox	`sandboxID`	Sandboxes	None configured
Volume	`volumeID`	Volumes	None configured

Record identity: Match on these fields before joining or deduplicating results; where none is specified, check the returned record first.
Start with: Resolve the parent identifier first.
None configured: No page continuation is configured for this resource. Check the response and any provider limits before treating it as a complete inventory.

Supported operations

Review the inputs before granting an action to an agent. Required inputs must be supplied, optional inputs narrow the request, and provider permissions apply in addition to Deixic policy.

Action: Can change provider state; review the target and inputs, then retain the result to avoid repeating completed work.

When the E2B task does not produce the expected result

Connected, but the expected data is missing

Check the identity behind the api key connection and its access to the specific resource; a successful connection does not establish access to every object.

Resolve parent resources first: Sandboxes, Volumes. A matching display name is not enough for a child lookup.

The answer covers only part of the data

Check the resource’s page coverage, query filters, and result limit, and have the agent state the account and time window it inspected, so a partial response yields a scoped answer.

The agent keeps doing the same work

Inspect the action history for repeated targets and inputs, keep the successful result’s identifiers with the task, and refresh a lookup only when the information changed.

A change is waiting or failed

Check whether the call awaits approval, was rejected by policy, lacks an input, or failed at the provider, and after a timeout inspect the destination before repeating a write.

See how an action proceeds and how to review an approval.

Questions about the E2B connector

Can I use my existing agent with E2B?

Yes: connect your agent to Deixic through MCP, choose which connected tools it can use, and Deixic checks calls routed through its gateway; Dex is available if your team also wants an agent.

Can an agent change data in E2B?

This connector supports 3 actions, listed on its overview page. Configure a connection and choose the tools and provider permissions your task needs; an available action is not permission for every agent to run it, and Deixic policy and any required approval still apply to calls through the gateway.

What do I need to connect E2B?

Prepare API key; the connection uses API key, and the connected identity’s provider permissions determine which resources it can access.

Does connecting E2B keep every answer up to date?

No: an earlier answer is still an earlier answer, so for a decision that depends on current state, have the agent refresh the source and retain the lookup time, and save stable instructions separately from facts that can change.
