How can you give Claude Code access to secrets safely?
Updated June 25, 2026
Short answer
The safer pattern is to create a named agent identity for Claude Code, grant it only the project secrets it needs, and let it resolve those secrets through a secure runtime API. The raw provider key should not be pasted into the chat transcript or committed to the repo.
What to do now
Do not paste the raw key into Claude Code. Create a Claude Code agent identity, assign it to the project, and grant only the credentials required for the current work.
Better pattern
Use a short-lived setup prompt to provision the agent, then let the agent resolve granted secrets through ScopeHold. The raw provider secret remains outside the chat transcript.
Avoid
Avoid copied production keys, broad .env files, shared human credentials, and generic agent tokens reused across unrelated projects.
Example
If Claude Code needs a Stripe test key, grant the Claude Code agent that one Stripe secret for the project and revoke the grant when the work no longer needs it.
Give an agent safe access in minutes
- 1.Store the credential.
- 2.Create a named agent identity.
- 3.Grant the access it needs.
- 4.Resolve it at runtime.
- 5.Review the audit entry.
No card required.
Secrets management for Claude Code
Secrets management for Claude Code should give the coding agent a scoped way to retrieve task-required credentials without placing raw API keys in the chat transcript, project files, or shared human accounts.
Do not paste raw keys into the conversation
Claude Code is useful because it can reason about files and run commands, but that does not mean raw credentials belong in chat. Chat history, screenshots, copied prompts, and tool logs can all become secondary places where a key exists.
Use a 10-minute provisioning prompt instead
A safer onboarding flow gives Claude Code a 10-minute, single-use provisioning token. Redeeming that token creates or rotates the Agent Key outside the chat transcript. The recommended CLI path stores the returned key in a named ScopeHold profile, while the API-only path remains available for runtimes that cannot or should not install the CLI.
Give the agent reusable guidance
ScopeHold Agent Guidance is available from the Runtime API so agents can refresh the safe operating pattern without a separate installer command. The generic endpoint works for any runtime, with Claude, Codex, and Cursor packaging variants where those formats help.
Grant project secrets deliberately
If Claude Code is working on one repository, it should only see that repository's project context and only resolve directly granted secrets. Visibility into a provider should not automatically mean access to every key under that provider.
- Create one Claude Code agent per durable working context.
- Assign it to the relevant project.
- Grant the specific API keys or login credentials it needs.
- Revoke or rotate agent access when the working context changes.
Reading this because it just happened to you?
ScopeHold gives every key one home: paste it once, grant it to your coding agents per project, see everything they touched, and revoke in one click. Free tier, five-minute setup, no card.
Fix it in 5 minutesPractical workflow
- 1Create the Claude Code agentName it after the project or operating role so audit history is readable later.
- 2Generate a provisioning promptUse a short-lived prompt that can be redeemed once instead of exposing a long-lived key.
- 3Register Agent Guidance when supportedIf Claude Code supports reusable skills or instruction files in your runtime, use the ScopeHold Agent Guidance variant as optional guidance. Do not block secret resolution on this step.
- 4Resolve only task-required secretsThe agent should inspect inventory, resolve only the needed values, apply them, verify the result, and clear temporary shell variables.

Frequently asked questions
What is the safest way to give Claude Code credentials?
Use a scoped agent identity and runtime secret resolution. Do not paste raw API keys or login credentials into the Claude Code chat.
Can Claude Code use secrets without storing them in the repo?
Yes. The agent can resolve a granted credential at runtime and use it for the task without writing the raw value into project files.
Should each Claude Code workspace have its own agent identity?
For durable or repeated work, yes. A named identity makes project grants, rotation, and audit events much easier to review.

Where ScopeHold fits
ScopeHold's agent provisioning flow is designed for this exact problem: keep the setup prompt convenient, but keep the raw Agent Key and provider secrets out of chat.
