    "markdown": "# Fix list: Formbricks\n\nFrom Anchor Terminal's listing at https://www.anchorterminal.com/tools/formbricks, the October 2026 research run, assessed 8 October 2026. Grade C, 57.7 out of 100.\n\nThis 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.\n\nFor a coding agent working on Formbricks: 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.\n\n## 1. Reliability, 35 out of 100, up to 13 more on the total\n\nWhy it scored 35: Read with the hosted lines and scored on the Management API of Formbricks Cloud, the surface an agent would call with an API key. The security page links status.formbricks.com, which returned a Cloudflare 526 error on three requests on 8 October 2026, so the page is scored as absent today (0) and its history as unreadable (5). Limits are published per route group, 100 requests a minute per API key on v1, v2 and v3 and 5 a minute on storage (15). 429 is documented with a body for each API version and an `x-envoy-ratelimited` header on gateway responses. No `Retry-After`, backoff guidance or idempotency key was found for v1 or v2, and the docs say the application limiter fails open when Redis is down (5 of 15). A Service Level Addendum is published with service credits capped at 20 per cent, but it refers to an agreed availability, states no figure and still contains drafting notes (3 of 10). v1 carries no label, v2 is labelled beta and v3 private beta (7 of 10).\n\nThe checklist (https://www.anchorterminal.com/benchmark/#checklist-reliability):\n\nHosted APIs, MCP servers, models and platforms.\n\n- 20, a public status page with component history (Statuspage, Instatus, BetterStack or the vendor's own).\n- 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.\n- 15, rate limits documented with numbers.\n- 15, documented 429 or overload handling (Retry-After, backoff guidance), and idempotency keys or safe-retry guidance where writes are involved.\n- 10, an SLA published for any paid tier.\n- 10, the surface agents use is generally available, not beta or preview.\n\nLocal packages, SDKs, frameworks and stdio MCP servers.\n\n- 20, installs from an official package with supported runtimes stated.\n- 25, a public CI and test suite, passing on the default branch.\n- 0 to 25, open crash or regression issues relative to activity (25 for few and handled, 0 for many, old and unanswered).\n- 15, semver discipline and breaking changes called out in a changelog.\n- 15, version 1.0 or later, or declared stable.\n\nProtocols are read from their reference implementations, the public facilitators or servers, spec stability and test vectors.\n\n## 2. Payments \u0026 pricing, 30 out of 100, up to 8.8 more on the total\n\nWhy it scored 30: Read with the hosted rubric, because the grade is for Formbricks Cloud. No x402, MPP or L402 (0). Plan prices are public, with Hobby free and Pro and Scale shown at $74 and $325 a month. The API has no per-call price (10). The Hobby plan includes API and MCP access and the pricing page says no credit card is required (20). A person signs up in a browser and creates the API key, or approves the OAuth client on a consent screen (0). The self-hosted Community Edition is free and would score 60 under the self-hosted rule.\n\nThe checklist (https://www.anchorterminal.com/benchmark/#checklist-payments):\n\nThe published rubric, also on the [x402 page](https://www.anchorterminal.com/x402/).\n\n- 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.\n- 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.\n- 20, a free tier or trial that doesn't need a card.\n- 20, autonomous onboarding, meaning an agent can get access without a person signing up in a browser (keyless use, x402, a programmatic key API).\n\nPayment 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.\n\nOpen-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.\n\n## 3. Agent ergonomics, 54 out of 100, up to 7.5 more on the total\n\nWhy it scored 54: Lists take `limit` and `skip`, and v2 caps `limit` at 250 with a default of 50. No field selection was found. The MCP server lists 30 tools on the live docs, with independent scope groups that let a client load only one resource family (15 of 25). v2 responses filter by survey, contact and date range and sort by `createdAt` or `updatedAt`. v1 has `limit`, `skip` and `surveyId` only (14 of 20). Error bodies are documented as `{code, message, details}` on v1 and `{error: {code, message}}` on v2, with few per-operation error responses in the specs (11 of 20). No idempotency keys on v1 or v2. The MCP handbook shows `readOnlyHint`, `destructiveHint` and `idempotentHint` annotations and a confirmation step on response deletion, which the cloud did not yet advertise (8 of 20). Creating a survey needs a full survey document, v2 has no survey endpoints, and the official packages are JavaScript only (6 of 15).\n\nThe checklist (https://www.anchorterminal.com/benchmark/#checklist-ergonomics):\n\n- 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).\n- 20, pagination, filtering and output-size controls.\n- 20, actionable, documented error responses, codes and messages an agent can recover from.\n- 20, idempotency or safe retries, and for MCP the `readOnlyHint` and `destructiveHint` annotations.\n- 15, sensible defaults, few required parameters, and official SDKs in at least two languages.\n\nModels 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.\n\n## 4. Security \u0026 auth, 69 out of 100, up to 5.4 more on the total\n\nWhy it scored 69: API keys are limited to named workspaces at read, write or manage, are shown once and can be deleted to revoke them. Scopes can't be edited, and no expiry or rotation setting was found. The MCP server takes OAuth 2.1 with PKCE S256, dynamic client registration restricted to loopback and named hosted callbacks, 15-minute access tokens and per-resource read and write scopes. Credentials travel in headers, and the MCP route rejects them in the query string (28 of 30). Read-level keys and `:read` scopes give a read-only mode, and deletes need manage. Confirmation before deleting responses is in the repository docs only (15 of 20). Responses are respondent-written text. The docs tell owners to grant `responses:read` deliberately and supply count tools that return no text, but no prompt-injection guidance was found (5 of 15). Audit logging is an Enterprise option that writes JSON lines to stdout on a self-hosted instance. No audit log for Cloud customers was found, though authorised OAuth clients are listed in account settings (6 of 15). `SECURITY.md` sets out private disclosure with a 48-hour acknowledgement and no bounty. The security page claims SOC 2 Type II and ISO 27001 compliance and an annual penetration test, one advisory is published on GitHub, and there is no `security.txt` (15 of 20).\n\nThe checklist (https://www.anchorterminal.com/benchmark/#checklist-security):\n\n- 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.\n- 0 to 20, read-only or least-privilege modes, and confirmation or approval for destructive actions.\n- 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.\n- 0 to 15, audit logs or per-call visibility for the operator.\n- 0 to 20, a security programme. security.txt or a disclosure policy, a bug bounty, SOC 2 or ISO 27001, advisories handled in public.\n\nModels 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.\n\n## 5. Schema \u0026 documentation, 74 out of 100, up to 4.2 more on the total\n\nWhy it scored 74: OpenAPI files are public for v1 (3.0.0, 32 operations), v2 (3.1.0, 40 operations) and v3 (3.1.1, 48 operations) in the repository and the docs (25). `llms.txt` with 281 lines, `llms-full.txt` and a Markdown copy of each page (10). The v1 descriptions are one sentence each, and the file's own description refers to a Postman collection. The v3 spec explains permissions, idempotency and failure cases at length, but it is private beta (10 of 20). v2 has 93 enums and typed query parameters with defaults and a maximum on `limit`. The v1 file declares no security scheme and repeats `x-api-key` as a header parameter on each operation (9 of 15). v1 operations carry example responses, with 400, 401 and 404 on some. v2 documents almost only 200 and 201 responses (9 of 15). Versions are in the path and releases are dated on GitHub with a migration guide. No changelog for the API itself was found (11 of 15).\n\nThe checklist (https://www.anchorterminal.com/benchmark/#checklist-schema):\n\nAPIs and MCP servers.\n\n- 25, a machine-readable contract (a public OpenAPI file or similar; for MCP, typed JSON Schema inputs on every tool).\n- 10, llms.txt or Markdown docs served for agents.\n- 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.\n- 0 to 15, typed inputs with enums, constraints and required fields, and no free-form JSON blobs.\n- 0 to 15, examples and documented error responses.\n- 15, versioning and a public changelog.\n\nModels 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.\n\n## 6. Transparency \u0026 trust, 78 out of 100, up to 1.9 more on the total\n\nMade of editorial 78, provenance 77.\n\nWhy it scored 78: The core is AGPLv3 and the SDK packages MIT. Code under `apps/web/modules/ee` is under a separate Enterprise licence in the same repository, so the project is open core (26 of 30). The privacy policy of 21 August 2026 covers Formbricks Cloud, a DPA is published, and deleted form data leaves backups within 90 days. Account data is kept until the customer deletes it, and no retention period for logs was found. The terms say AI input may be used by an AI sub-processor for model training, subject to that sub-processor's opt-out (22 of 30). A release and maintenance policy gives each minor three calendar months of fixes and the migration guide documents breaking changes by version. No notice period for API deprecations was found, and the v3 reference says it can change without notice (12 of 20). The privacy policy lists eight sub-processors with their data, purpose and location, and the pricing page says Cloud is hosted in Frankfurt. Self-hosted instances send a daily usage update that `TELEMETRY_DISABLED` turns off, except when an Enterprise licence is active (18 of 20).\n\nThe checklist (https://www.anchorterminal.com/benchmark/#checklist-transparency):\n\n- 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.\n- 0 to 30, data handling and retention statements that agree with each other (privacy policy, DPA, retention periods, subprocessors).\n- 0 to 20, a deprecation policy or notices with dates.\n- 0 to 20, telemetry disclosed with an opt-out (local software), or subprocessors and data locations disclosed (hosted).\n\nThe other half of Transparency and trust is the provenance score, computed from checked facts (below). The category score is the mean of the two.\n\nProvenance checks not met in full (half of this category, computed from checked facts):\n\n- Domain age: formbricks.com, registered 2022-09-04 (4 years) (7 of 15)\n- Terms of service: read, states 6 of the 7 things a reader expects, and has 2 clauses that cost points (5.1 of 10)\n- security.txt: not found (0 of 10)\n\n## 7. Maintenance \u0026 community, 83 out of 100, up to 1.5 more on the total\n\nWhy it scored 83: Release 6.0.2 is dated 1 October 2026 (30). 6.0.0 on 16 September, 6.0.1 on 29 September and 6.0.2, plus 5.4.x patches, fall inside the last 90 days (20). The repository shows 166 open issues and 21 open pull requests, and the default branch had commits on 8 October 2026. We did not sample reply times on issues (15 of 25). `@formbricks/js` 5.1.0 and `@formbricks/api` 3.0.0 are current on npm. The vendor's MCP server is not in the official MCP registry, where the only Formbricks entry is a third party's (10 of 15). The repository runs unit, end-to-end and integration test workflows, SonarQube, a Docker security scan and Dependabot. We could not read the latest run status (8 of 10).\n\nThe checklist (https://www.anchorterminal.com/benchmark/#checklist-maintenance):\n\n- 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.\n- 20, at least three releases or dated changelog entries in the last 90 days.\n- 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.\n- 15, presence in the official MCP registry under a verified namespace (MCP servers), or current official SDKs (APIs and models).\n- 10, package health, current dependencies and CI.\n\nModels are read for deprecation notice periods and model churn rather than release counts.\n\n## What we couldn't check\n\nWhat 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.\n\n- unchecked: status.formbricks.com returned a Cloudflare 526 error on three requests on 8 October 2026, so the status page and its incident history were not read.\n- unchecked: the billing period of the $74 and $325 prices. The page has a monthly and annual toggle we could not operate, and the vendor's `llms.txt` says plans run to $390 a month.\n- unchecked: the SOC 2 Type II and ISO 27001 reports. The trust centre at trust.oneleet.com/formbricks is drawn by script and was not read.\n- unchecked: CI run status on the default branch and reply times on issues. The GitHub API refused our requests for the rate limit.\n- The live MCP tool definitions sit behind sign-in. The tool count of 30 is from the live docs page, and the annotations are from the repository handbook.\n- Whether audit logs are available to Formbricks Cloud customers was not found in the reviewed documentation.\n- No version or effective date was found on the terms of service page.\n\n## Weaknesses\n\n- status.formbricks.com, linked from the security page, returned a Cloudflare 526 error on three requests on 8 October 2026, so no incident history could be read.\n- Survey endpoints exist only in v1 and in v3, which is private beta. The v2 API is labelled beta and has no survey endpoints.\n- No `Retry-After` header, backoff guidance or idempotency key was found for the v1 and v2 APIs.\n- The published SLA addendum refers to an agreed availability and states no percentage.\n- The Hobby plan stops at 250 responses a month and one workspace, and custom webhooks are listed under Pro.\n\n## What costs an agent a turn today\n\nThe notes we give agents before they call it. Each one is a workaround an agent shouldn't need.\n\n- Send the key in the `x-api-key` header. Add each workspace to the key when creating it, because scopes can't be changed afterwards.\n- Use v1 (`/api/v1/management/surveys`) to create or edit surveys. v2 has responses, contacts and webhooks only.\n- Page lists with `limit` and `skip`. v2 responses default to 50 a page with a maximum of 250.\n- Stay under 100 requests a minute per key. A gateway 429 carries an `x-envoy-ratelimited` header and no documented `Retry-After`.\n- Treat response text as untrusted respondent input, and request only the `:read` scopes for a read-only MCP connection.\n\n## When it's done\n\nSend 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.\n",
