What E2B (BYOK) is for

E2B (BYOK) lets an AI assistant read your own E2B data through the E2B API with a key you supply (API key). Read-only: 9 tools (list_sandboxes, get_sandbox, get_sandbox_metrics, get_sandbox_logs, list_templates, list_template_builds, list_snapshots, list_volumes, get_team_metrics). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.e2b.app. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by E2B. E2B and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which E2B sandboxes are running right now?"
• "Show the details of one E2B sandbox"
• "How much CPU and memory is my E2B sandbox using?"
• "Show the latest error logs of an E2B sandbox"
• "Which E2B templates do I have and which built successfully?"
• "Show the build history of an E2B template"

What it does

• list_sandboxes: List your E2B sandboxes (running and paused) newest first, with template, state, start and end time, CPU, memory and disk size.
• get_sandbox: Get one sandbox: template, state, start and end time, resources, whether internet access is allowed and its lifecycle (auto-resume, action on timeout).
• get_sandbox_metrics: Get CPU, memory and disk usage samples of one sandbox over a time window.
• get_sandbox_logs: Read the log lines of one sandbox (up to 1000 per call), optionally by level or search text; page with the cursor.
• list_templates: List the sandbox templates your team can use, with resources, public flag, aliases, build status, spawn count and last use.
• list_template_builds: List the builds of one template (status, resources, timestamps), newest first.
• list_snapshots: List persistent snapshots of your sandboxes with their IDs and names, optionally for one sandbox.
• list_volumes: List the persistent volumes of your team with ID and name.
• get_team_metrics: Get your team's concurrent sandbox count and sandbox start rate over time. Needs your team ID, shown in the E2B dashboard.

BYOK key

You bring your own E2B API key (https://console.e2b.dev/?tab=keys). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.e2b.app over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

• https://docs.e2b.dev/api-reference (the API this connector calls, with a BYOK key)

Live from the E2B API (api.e2b.app) with a BYOK key; documentation: https://docs.e2b.dev/api-reference. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by E2B. E2B and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your E2B account.

Built for: Worldwide. Languages: English.

E2B (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What E2B (BYOK) is. E2B (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own E2B data: Read your E2B sandboxes, templates, snapshots, volumes, logs and resource metrics with your own API key. You bring your own E2B API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one E2B call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.e2b.app, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If E2B rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What E2B receives. The request we make on your behalf, including the key and the arguments, under E2B's own terms and privacy policy. E2B acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer E2B gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your E2B data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. E2B (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at E2B at any time to end all access.

Children. E2B (BYOK) is a general-audience service operated by the adult using the assistant, under E2B's own age rules.

Changes. We will post changes here with a new effective date.
