The problem with letting an agent hold your keys
OpenClaw is valuable precisely because it operates autonomously — it reads a task, decides which APIs to call, and executes without waiting for step-by-step confirmation. That autonomy is also the risk. When OpenClaw runs with credentials in its context window, environment variables, or configuration files, it’s carrying keys that can reach far beyond the specific workflow you had in mind.
Three failure modes come up consistently:
- Overly broad credentials — OpenClaw receives an API key with full account access when the task only needs read access to one resource type.
- No rate guardrails — a retry loop or a misunderstood task causes the agent to hammer an endpoint, exhausting your quota or triggering vendor-side blocks.
- No audit trail — when something goes wrong, you have no record of which API was called, with what parameters, or what the response contained.
A gateway between OpenClaw and the APIs it calls solves all three — without requiring any changes to the agent itself.
Step 1: Move credentials out of the agent’s context
Replace the real vendor API key in OpenClaw’s configuration with a proxy-type RequestRocket credential. The vendor key stays inside RequestRocket; the agent never sees it.
First, create a target for the upstream API:
POST /clients/{clientId}/targets
{
"targetName": "github-api",
"targetBaseURL": "https://api.github.com",
"targetRegion": "us-east-1"
}Store the real GitHub token as a target-type credential. This never leaves RequestRocket:
POST /clients/{clientId}/credentials
{
"credentialType": "target",
"credentialAuthType": "bearer",
"credentialName": "github-token-production",
"credentialRegion": "us-east-1",
"credentialSecret": {
"token": "ghp_xxxxxxxxxxxxxx"
}
}Create a proxy-type credential for OpenClaw to present. This is the only secret the agent needs:
POST /clients/{clientId}/credentials
{
"credentialType": "proxy",
"credentialAuthType": "key",
"credentialName": "openclaw-github-agent",
"credentialRegion": "us-east-1",
"credentialSecret": {
"key": "rr_live_xxxxxxxxxxxxxx"
}
}If the agent key is compromised, rotate it independently of the real GitHub token. The vendor key is never exposed to the agent.
Step 2: Create a proxy with deny-by-default
Wire the target and both credentials into a proxy, and set proxyDefaultRuleEffect: "deny":
POST /clients/{clientId}/proxies
{
"proxyName": "openclaw-github",
"proxyRegion": "us-east-1",
"proxyProxyCredentialId": "<openclaw-github-agent-id>",
"proxyTargetId": "<github-api-id>",
"proxyTargetCredentialId": "<github-token-production-id>",
"proxyDefaultRuleEffect": "deny"
}With proxyDefaultRuleEffect: "deny", every request is blocked unless an explicit allow rule permits it. OpenClaw cannot call any endpoint not covered by a rule, even if the agent decides to try.
Step 3: Allow only the paths the task requires
A code review agent that reads pull requests and posts comments doesn’t need access to delete repositories, manage billing, or administer organisation members. Add allow rules for exactly the paths the task requires:
POST /clients/{clientId}/proxies/{proxyId}/rules
{
"effect": "allow",
"methods": ["GET"],
"path": {
"path": { "pattern": "^/repos/[^/]+/[^/]+/pulls" },
"presence": "must_exist"
},
"priority": 10,
"notes": "OpenClaw: read pull requests"
}POST /clients/{clientId}/proxies/{proxyId}/rules
{
"effect": "allow",
"methods": ["POST"],
"path": {
"path": { "pattern": "^/repos/[^/]+/[^/]+/issues/[^/]+/comments$" },
"presence": "must_exist"
},
"priority": 9,
"notes": "OpenClaw: post PR review comments"
}Everything else — repository administration, organisation settings, actions workflows — is denied by default.
Step 4: Cap request volume
Agents don’t always model backoff correctly. A 429 from GitHub, misread by the agent as a signal to retry harder, can exhaust your rate limit across the account. Rate limits are enforced on a proxy through meters. Create a request_count meter with meterMode: "all" to cap the total volume across all methods and paths:
POST /clients/{clientId}/proxies/{proxyId}/meters
{
"meterType": "request_count",
"meterActive": true,
"meterMode": "all",
"limits": {
"minute": 60,
"day": 2000
},
"notes": "Total request cap for OpenClaw GitHub agent"
}When this meter’s limit is reached, the gateway returns a rate-limit response and the request is not forwarded upstream. Cap retry attempts and backoff at the proxy level to prevent runaway behaviour if upstream calls fail:
PUT /clients/{clientId}/proxies/{proxyId}
{
"proxyMaxRetries": 2,
"proxyMaxBackoff": 15
}proxyMaxRetries: 2 means a failed request gets at most two retries — three total attempts. proxyMaxBackoff: 15 caps the exponential backoff at 15 seconds, so the retry window doesn’t extend indefinitely.
Step 5: Strip sensitive data from responses
GitHub API responses include data beyond what a code review agent needs: private email addresses, internal organisation identifiers, contributor profile metadata, and more. A filter removes these before the response reaches the agent:
POST /clients/{clientId}/proxies/{proxyId}/filters
{
"methods": ["GET"],
"operations": [
{
"effect": "destroy",
"jsonPath": {
"pattern": "\\.(email|node_id|gravatar_id|followers_url|following_url|gists_url|starred_url|subscriptions_url|organizations_url|received_events_url)$",
"flags": "i"
},
"notes": "Strip internal and PII fields from GitHub API responses"
}
],
"notes": "Response scrubbing for OpenClaw code review agent"
}The agent’s context window contains only the data the task actually requires.
What you gain
After these five steps:
- OpenClaw authenticates with a scoped proxy key, not the real vendor credential.
- Every request is path-restricted by explicit allow rules; anything outside scope is blocked at the gateway before it reaches GitHub.
- Runaway retry behaviour is capped before it drains your quota.
- Sensitive response fields are stripped before the agent processes the payload.
- Every call is logged with path, method, status, and timing — a complete audit trail you can query at any time.
Rotating the real vendor key no longer requires touching OpenClaw’s configuration. Changing the task scope means updating a rule, not redeploying the agent.
