Bitwarden Secrets Manager by Bitwarden

# Fix list: Bitwarden Secrets Manager

From Anchor Terminal's listing at https://www.anchorterminal.com/tools/bitwarden-secrets-manager, the October 2026 research run, assessed 1 October 2026. Grade C, 57.1 out of 100.

This is everything the published grade says the listing lacks, the biggest possible gain to the total first. It comes from the reason given for each score, the checklist each category was scored against (https://www.anchorterminal.com/benchmark/#checklist), the provenance checks, the deductions, what we couldn't check and what the review panel asked for. A fix counts at the next check, once it's public.

For a coding agent working on Bitwarden Secrets Manager: work through the items below in the product, its docs and its public pages. Each category gives the reason for its score, with the points each checklist item earned, and the checklist itself, so the gap is the items that earned less than their points. Change the product, not the wording, and keep a note of what you changed and where it's published.

## 1. Payments & pricing, 25 out of 100, up to 9.4 more on the total

Why it scored 25: No x402, MPP or L402 (0). Teams $6 and Enterprise $12 per user a month with 20 or 50 machine accounts and $1 per extra machine account are public (10). A free plan with 2 users, 3 projects and 3 machine accounts, and a 14-day trial; the pages don't say whether a card is taken (15 of 20). A person signs up and creates the machine account and token in the web app (0).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-payments):

The published rubric, also on the [x402 page](https://www.anchorterminal.com/x402/).

- 40, a machine payment protocol (x402, MPP or L402) on the tool's own endpoints. 10 to 30 when it covers only some endpoints or only goes through a third party, and the note says which.
- 20, per-call or per-unit pricing published without a login. 10 for public plan-only pricing, 0 for "contact sales" or prices behind a login.
- 20, a free tier or trial that doesn't need a card.
- 20, autonomous onboarding, meaning an agent can get access without a person signing up in a browser (keyless use, x402, a programmatic key API).

Payment platforms and agent wallets rarely charge for their own API over a machine protocol, so the first line has steps for them, and the highest one that applies counts. 40 when x402, MPP or L402 runs on all their own endpoints, 30 when it runs on part of their own API, 25 when their merchants can accept one, 20 for running a facilitator, 15 for paying as a buyer, and 0 when the only protocol is their own. Merchant acceptance sits above a facilitator because the platform's own customers can charge agents through it, while a facilitator settles for sellers who wire up the protocol themselves. The counter-argument (a facilitator does more for the protocol as a whole) has a point. Each note says which step applied.

Open-source software you run yourself is scored on its hosted or paid option if it has one. A free, self-hosted package with nothing to buy gets 20, 20 and 20 for the last three lines, and 0 to 40 for the first only if it ships a payment protocol.

## 2. Agent ergonomics, 52 out of 100, up to 7.8 more on the total

Why it scored 52: No MCP server for Secrets Manager, so the cost is CLI output, which comes as json, yaml, env, tsv, table or none (15 of 25). Secrets list by project and are fetched one by one by UUID, with no name lookup, paging or filtering (8 of 20). Error messages are a known weak spot, with open issues for a wrong message on a bad token (#1561) and a bad message on a missing write permission (#1287) (8 of 20). No idempotency keys or retry guidance, and secret writes are addressed by ID (6 of 20). SDKs in eight languages plus bws run, and the access token is the only required input (15).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-ergonomics):

- 0 to 25, context cost. For MCP, the number and size of the tool definitions (25 for ten or fewer compact tools, 15 for 11 to 30, 5 for more than 30, plus up to 10 back for toolsets, dynamic loading or read-only subsets). For APIs, whether responses can be sized (field selection, limits, summaries).
- 20, pagination, filtering and output-size controls.
- 20, actionable, documented error responses, codes and messages an agent can recover from.
- 20, idempotency or safe retries, and for MCP the `readOnlyHint` and `destructiveHint` annotations.
- 15, sensible defaults, few required parameters, and official SDKs in at least two languages.

Models are read for tool use, structured output, prompt caching, context length, batch and SDKs. Frameworks for how much code and how many defaults a tool-calling agent with MCP needs.

## 3. Schema & documentation, 53 out of 100, up to 7.6 more on the total

Why it scored 53: No OpenAPI for the Secrets Manager API; the SDK generates JSON schemas for its own command interface, which the language bindings are built from (10 of 25). bitwarden.com/llms.txt answers with an index of about 60 links, none to the Secrets Manager CLI, SDK or machine account help pages (3 of 10). Help pages explain each concept and the CLI has --help for every command, but nothing says when to use the SDK rather than bws run (12 of 20). The SDKs are typed from those generated schemas (12 of 15). Examples on the help pages and READMEs, while open issues #1561, #1287 and #1331 report wrong or bare error messages (8 of 15). Semver tags and GitHub releases, but the crate changelogs stopped in September 2024 (8 of 15).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-schema):

APIs and MCP servers.

- 25, a machine-readable contract (a public OpenAPI file or similar; for MCP, typed JSON Schema inputs on every tool).
- 10, llms.txt or Markdown docs served for agents.
- 0 to 20, descriptions that say what a tool is for, when to use it and when not to, read from the tool definitions in the source or the API reference.
- 0 to 15, typed inputs with enums, constraints and required fields, and no free-form JSON blobs.
- 0 to 15, examples and documented error responses.
- 15, versioning and a public changelog.

Models are read from the API reference, the OpenAPI file, llms.txt, the structured-output and tool-use docs and the model cards. Frameworks from docs a model can follow, typed interfaces, examples and the API reference.

## 4. Reliability, 71 out of 100, up to 5.8 more on the total

Why it scored 71: Graded as an SDK, since that's the listing's kind. Official packages on crates.io (bws), PyPI (bitwarden-sdk), npm, Go, NuGet and Maven, with a minimum Rust version of 1.88.0 stated, but the npm package is still 1.0.0 from 30 September 2024 (17 of 20). Rust, Go and Python test workflows run on pushes to main; we couldn't see whether they pass (20 of 25). 33 open issues, nearly all bugs, including a Python SDK segfault open since 23 July 2025 (#1288), a .NET failure on Linux from 29 May 2026 (#1522) and a 15-minute CLI timeout (#1386) (12 of 25). Semver tags with 2.0.0 marked breaking, but the bws changelog stops at 1.0.0 from 26 September 2024 (7 of 15). 2.1.0 is past 1.0 (15). The hosted API behind it has a Hund.io status page that showed one 38-minute spell of elevated US API errors on 29 September 2026 and five planned maintenance windows since 7 July.

The checklist (https://www.anchorterminal.com/benchmark/#checklist-reliability):

Hosted APIs, MCP servers, models and platforms.

- 20, a public status page with component history (Statuspage, Instatus, BetterStack or the vendor's own).
- 0 to 30, the incident record for the last 90 days on that page. 30 for a clean record or trivial incidents only, 20 for minor incidents only, 10 for one major outage (an hour or more of a core API down, or errors across the board), 0 for several. 5 when there's no history we could read, and the note says so.
- 15, rate limits documented with numbers.
- 15, documented 429 or overload handling (Retry-After, backoff guidance), and idempotency keys or safe-retry guidance where writes are involved.
- 10, an SLA published for any paid tier.
- 10, the surface agents use is generally available, not beta or preview.

Local packages, SDKs, frameworks and stdio MCP servers.

- 20, installs from an official package with supported runtimes stated.
- 25, a public CI and test suite, passing on the default branch.
- 0 to 25, open crash or regression issues relative to activity (25 for few and handled, 0 for many, old and unanswered).
- 15, semver discipline and breaking changes called out in a changelog.
- 15, version 1.0 or later, or declared stable.

Protocols are read from their reference implementations, the public facilitators or servers, spec stability and test vectors.

## 5. Maintenance & community, 36 out of 100, up to 5.6 more on the total

Why it scored 36: Newest releases are 2.1.0 for Rust, Python and bws on 20 May 2026 and Go 2.1.0 on 22 May, 132 days before this check (10). No release in the last 90 days (0). 33 open issues, with bug reports from July 2025 still open and no fix released since May (10 of 25). Rust, Python and Go SDKs are current at 2.1.0, but the npm package is 1.0.0 from September 2024, and the official MCP server covers the password vault only (7 of 15). Renovate keeps dependencies current, CI covers each binding, and the internal crates moved to 4.0.0 on 30 September 2026 (9 of 10).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-maintenance):

- 0 to 30, time since the last release, or the last published model or API change for a closed service. 30 within 30 days, 20 within 90, 10 within 180, 0 older.
- 20, at least three releases or dated changelog entries in the last 90 days.
- 0 to 25, responsiveness. Issues and pull requests answered on GitHub (the open issues and how recent the replies are). For closed services, a public changelog and a support or community channel that answers, 0 to 15.
- 15, presence in the official MCP registry under a verified namespace (MCP servers), or current official SDKs (APIs and models).
- 10, package health, current dependencies and CI.

Models are read for deprecation notice periods and model churn rather than release counts.

## 6. Security & auth, 76 out of 100, up to 4.2 more on the total

Why it scored 76: Machine account access tokens are revocable, optionally expire (default never), are never stored by Bitwarden, and inherit the account's Can read or Can read, write grant per project, while secrets decrypt only on the client. A revoked token's live session can keep reading for up to an hour, and there's no workload identity login (23 of 30). Can read on one project gives a read-only agent, but there's no approval step for writes or deletes (14 of 20). Secrets aren't untrusted content, and bws run puts them in the environment rather than in a model's context (10). Each machine account has an event log of secret access, retained indefinitely and exportable, on Teams and Enterprise only (12 of 15). SOC 2 Type II, SOC 3, ISO 27001 and a HackerOne bounty, but no security.txt per the 30 September check (17 of 20).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-security):

- 0 to 30, the credential model. 30 for OAuth 2.1 with scopes, or scoped and revocable keys with rotation. 20 for plain revocable API keys. 10 for one all-powerful key. 10 off when a secret can travel in a URL query string as a documented option.
- 0 to 20, read-only or least-privilege modes, and confirmation or approval for destructive actions.
- 0 to 15, prompt-injection posture where the tool returns untrusted content (documented mitigations or guidance). A tool that returns no untrusted content gets 10.
- 0 to 15, audit logs or per-call visibility for the operator.
- 0 to 20, a security programme. security.txt or a disclosure policy, a bug bounty, SOC 2 or ISO 27001, advisories handled in public.

Models are read for retention, whether API data trains models (and whether that's off by default), zero-retention options and certifications. Frameworks for telemetry defaults, approval hooks, guardrails and sandboxing.

## 7. Transparency & trust, 71 out of 100, up to 2.5 more on the total

Made of editorial 52, provenance 90.

Why it scored 71: Source is on GitHub, but the SDK and bws ship under Bitwarden's own SDK licence, which limits use to applications that work with Bitwarden; it isn't an OSI licence (12 of 30). The privacy policy (revised April 2024, per the 30 September check) and the compliance page agree on US or EU hosting on Azure, with GDPR and DPF statements; we didn't read a DPA or subprocessor list (18 of 30). No SDK deprecation policy found; the only dated removal is the action type commands in bws 1.0.0 (6 of 20). No telemetry in the bws or SDK source, and hosting regions are disclosed (16 of 20).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-transparency):

- 0 to 30, source availability and licence clarity. 30 for open source under an OSI licence, 15 for closed with clear terms, 0 for unclear terms.
- 0 to 30, data handling and retention statements that agree with each other (privacy policy, DPA, retention periods, subprocessors).
- 0 to 20, a deprecation policy or notices with dates.
- 0 to 20, telemetry disclosed with an opt-out (local software), or subprocessors and data locations disclosed (hosted).

The other half of Transparency and trust is the provenance score, computed from checked facts (below). The category score is the mean of the two.

Provenance checks not met in full (half of this category, computed from checked facts):

- security.txt: not found (0 of 10)

## What we couldn't check

What we couldn't read counted as absent. Publishing it on a page a plain HTTP fetch can read (not only in a browser) lets the next check count it.

- Whether the CI test workflows pass on main; we read them but couldn't see run results.
- Whether the free plan or the 14-day trial asks for a card.
- Whether self-hosting Secrets Manager is available now; the product page lists it on Enterprise and the plans help page says coming soon.
- unchecked: a DPA and subprocessor list, and security.txt (relied on from the 30 September check).
- Whether bitwarden.com/llms.txt is meant as an llms.txt; it answers with a short index that doesn't reach the help pages, so we left the listing's llmsTxt field empty.

## Weaknesses

- No release since 22 May 2026, and the npm SDK is still 1.0.0 from September 2024
- 33 open issues, mostly bugs, including a Python SDK segfault open since July 2025
- Revoked tokens keep working for up to an hour on already-authenticated machines
- No rotation, dynamic secrets, workload identity login or MCP server for Secrets Manager
- SDK and CLI under Bitwarden's own SDK licence, and no OpenAPI for the secrets API

## What costs an agent a turn today

The notes we give agents before they call it. Each one is a workaround an agent shouldn't need.

- Create one machine account per agent with Can read on one project, and give its token an expiry date rather than the default of never
- Run the agent under `bws run -- <cmd>` so secrets arrive as environment variables and aren't written to disk or into the context
- Fetch with `bws secret list <project-id> --output json` once per run; `bws secret get` needs the secret's UUID, not its name
- Set BWS_SERVER_URL for an EU organisation or a self-hosted server; the default is the US cloud
- Rotate the secret's value as well as revoking the token in an emergency, since a live session can read for up to an hour

## What the review panel asked for

- changelog entries for 2.x
- a current npm release
- immediate session revocation
- expiry on by default

## When it's done

Send what changed and where it's published as a dispute (https://www.anchorterminal.com/builders/#disputes, or `POST https://www.anchorterminal.com/api/v1/contact` with `"kind": "dispute"`). Disputes are answered in public, and the listing is checked again by the same checklist. Paying for an audit or a listing claim changes nothing here.
