1Password
Inject 1Password secrets into an AI agent's tool calls without exposing them in chat.
Quick answer
What it does
Resolves 1Password secret references at MCP tool-call time so cleartext credentials never enter the conversation context.
Best for
- Reference-only secret injection
- Multi-credential workflows
- Team-shared vaults for AI tools
- Audit trails on agent secret use
Not for
- Workflows with one local API key in env
- Cases where the downstream tool cannot accept a runtime-resolved secret

ChatGPT → Apps directorynone1Password doesn't ship a hosted HTTPS endpoint today. ChatGPT supports remote MCP servers only — to use this server in ChatGPT you'll need to deploy it to a public HTTPS URL first (e.g. via Cloudflare Workers or Vercel) or wait for an official remote build.

Security & scope
- Access scope
- Read-only
- Sandbox
- 1Password service-account token. Scoped to specific vaults at the 1Password side. The MCP itself never persists cleartext — every resolution happens inline at tool-call time.
- Gotchas
- The service-account token IS a secret. Store it in the OS credential store, not in a config file.
- Resolve-only — there is no write tool to create or update items. Use the 1Password app or CLI for that.
- Audit logs are at the 1Password side. Pair the MCP with a periodic review of service-account access events.
Agent prompt pack
— copy into Claude, Cursor, or ChatGPT.Recommend the best MCP servers for [task: e.g. security work] in [client: Claude]. Constraints: - Prefer tools that are [official | open-source | read-only] — pick what matters for my use case. - Exclude MCPs that require [e.g. a paid plan, OAuth-only flows, remote-only transport]. - Return at most 3 picks, ranked. For each pick include: 1. One-sentence rationale. 2. The ready-to-paste install snippet for my client. 3. Any required secrets I need to create before installing. Cross-check the top-mcps.com listing: https://top-mcps.com/top-mcps-for-security
Compare 1Password MCP vs [HashiCorp Vault MCP] for the following job: [describe the job, e.g. "let an agent create GitHub issues on bug triage"]. Judge them on: - Setup time and complexity (what a new user hits first). - Auth model (none / API key / OAuth 2.1) and credential risk. - Transport (stdio / Streamable HTTP / SSE) and where the server runs. - Required secrets and the blast radius if they leak. - Operational risk in an unattended agent loop. - Which one is "good enough" for a weekend prototype vs. production. End with one sentence: which should I pick for my scenario, which is: [my scenario]. References: - https://top-mcps.com/mcp/1password - top-mcps.com listing for HashiCorp Vault
Install the 1Password MCP server for my [client: Claude] at the default config path for that client. Use the exact install snippet published at https://top-mcps.com/mcp/1password (fetch https://top-mcps.com/mcp/1password.json for the canonical server.json if you can read URLs). Before finishing: 1. Create the required secrets (OP_SERVICE_ACCOUNT_TOKEN) and put them in the appropriate env block — do not hard-code them. 2. Restart or reload the client so it picks up the new server. 3. Verify the server is connected (green / running state) and at least one tool is listed. 4. If anything fails, read the client's MCP logs and report the exact error — do not silently retry. Confirm when done and list the tools the server now exposes.
