Give your agent a pass for 20 calls and 10 minutes.

The agent says why it needs access. You approve in Telegram or on the web. The gateway adds your key to each call and closes the pass when the limit runs out.

sales-agent asks for access to Bitrix24

Waiting for you

For: 10 min
Calls, up to: 20

Agent will see: deals and leads without names, phones, e‑mails or comments

Weekly report: leads that changed status since Monday
Written by the agent, not checked

Example request. Telegram and Slack get the same facts: agent, service, time, calls, reason.

An agent can do everything its key can.

Agents read .env files even when deny rules say no.claude-code issue #24846
A prompt injection in a web page or a ticket can ask the agent to send its keys somewhere else.Prompt injection
A key with full rights gives the agent full rights, for as long as the key lives.Blast radius
A sandbox does not help once the key is already in the agent's memory.Sandboxing
A CRM webhook link is a key too: whoever has the link gets its rights.CRM webhooks

How a call goes through

1
The agent asks
It names the service, how long, how many calls, and why.
2
You decide
The request comes to Telegram, Slack or e‑mail with all the facts. Approve or deny in Telegram or on the web.
3
The gateway makes the call
It adds your key, counts the call and filters the response. When the time or the calls run out, the pass stops working.

Revoke a pass or a whole agent at any time. It takes effect on the next call.

An agent asks for access, the owner approves the request in the web UI, the call goes through the gateway — Recorded on the demo build. An agent asks, the owner approves, the call goes through.

You decide what comes back from your CRM.

CRM keys are read-only by default. You tick the data types and fields the agent can see, and the gateway removes the rest from the response.

Bitrix24 returns crm.lead.list, example

{
  "result": [{
    "ID": "4182",
    "TITLE": "Anna Lee, website redesign",
    "STATUS_ID": "IN_PROCESS",
    "ASSIGNED_BY_ID": "12",
    "OPPORTUNITY": "12400.00",
    "CURRENCY_ID": "USD",
    "NAME": "Anna",
    "LAST_NAME": "Lee",
    "PHONE": [{ "VALUE": "+1 415 555 0134" }],
    "EMAIL": [{ "VALUE": "anna.lee@example.com" }],
    "COMMENTS": "Asked for a discount, call after 5 pm"
  }]
}

The agent gets with a field filter

{
  "result": [{
    "ID": "4182",
    "STATUS_ID": "IN_PROCESS",
    "ASSIGNED_BY_ID": "12",
    "OPPORTUNITY": "12400.00",
    "CURRENCY_ID": "USD"
  }]
}

If you allow a free-text field, turn on mask: e‑mails, phone numbers written with +, card numbers and IBANs become ****. Before a request is approved, you see an “Agent will see” line.

What it protects, and what it does not

Protects

Keys stay on your server.Encrypted in AWS SSM or in an encrypted file vault. Agents get passes, never keys.
Every key has a policy.Always, ask or deny, with the channels and hours you choose.
Read-only by default for CRM and support keys.A write returns 403 and spends no quota.
Weakening a rule needs a fresh 2FA code.Tightening needs none.
No secrets in logs.Key values never appear in logs, URLs, responses or errors.
Fails closed.If the vault or the database is down, agents get 503.

Does not protect

Against root on the server.Anyone with root or cloud admin rights can read the keys.
Against misuse inside the pass.Within its limits the agent can make any call the key allows. Give it narrow keys.
From the service you call.It sees the key and the data you send.
Every kind of personal data.Mask does not find names and addresses, or phone numbers written without +.
Your own accounts.If someone takes over your Telegram or e‑mail, they can approve requests.

Works with the agents you already use

Connect over MCP (Streamable HTTP with a bearer token) or plain HTTP. Any script that can send an HTTP request works too.

Install on your server

Debian 12 or Ubuntu 24.04 and a domain pointed at the server. The script installs Node.js 22, Caddy and systemd services, then prints a one-time setup link.

curl -fsSL https://raw.githubusercontent.com/maximskorohod/agentkeygate/v1.0.1/scripts/setup.sh -o setup.sh
echo "40c9cc59c14ca795263b537325f624f709f3e2e670d93221d8e99ddd76147a15  setup.sh" | sha256sum -c -
sudo bash setup.sh --domain gw.example.com
# outside AWS add: --vault file
