Powens 33

The public changelog is a Notion page drawn by script and was not read, so recency is taken from the docs sitemap. The newest reference page change is dated 15 September 2026, 24 days before the check, scored 20 of 30 because docs metadata is weaker evidence than a release note. Docs pages changed on two dates in the last 90 days, 31 August and 15 September, and dated changelog entries could not be counted (0 of 20). Closed service with a linked changelog, a support desk on Jira and support hours of 9.30am to 7pm on working days in the conditions of sale (8 of 15). The iOS SDK is at 1.0.0-beta with its last commit on 1 October 2024, Android is marked coming soon, and no server-side SDK was found (3 of 15). The SDK repository holds a binary framework with no CI workflow (2 of 10).

BankMCP 63

Read with the local-software lines. Installs from npm as bankmcp with Node 24 or later stated (20). CI runs typecheck and tests on every push and pull request, with 12 test files; we didn't see the run results (18 of 25). Few issues, and the one we saw (scoping OAuth tokens for attestation) was fixed by a merged pull request on 22 October (20 of 25). Tags follow 0.1.x, but there is no changelog file and npm's latest (0.1.14) lags the newest tag (0.1.15) (5 of 15). Pre-1.0 (0). 20 + 18 + 20 + 5 + 0 = 63.

Powens 27

Graded with the hosted lines. No status page is linked from the home page, the product pages or the docs read. status.powens.com was a guess that our network could not reach, so this is scored absent and listed as unchecked (0 of 20). No readable incident history (5 of 30). The fair usage policy publishes sandbox limits of 30 calls a minute and 86,400 a day. Production limits are not published (10 of 15). The policy says rate limiting exists and asks for webhooks before polling. No 429 status, Retry-After, backoff guidance or idempotency key was found, and the response code table has no 429 (2 of 15). The conditions of sale carry no uptime figure. The site states 99.9 per cent historical API availability and a committed 95 per cent connection success rate as claims, not as a published SLA (0). Version 2.0 is the current API with no beta label (10).

BankMCP 75

All 15 tools have typed zod input schemas (25). bankmcp.dk serves llms.txt, and the README documents each tool (10). Descriptions say what each tool returns and how to chain them, such as passing the exact bank name to start_consent (15 of 20). Typed inputs with lengths and optional filters (12 of 15). README examples and prompts; errors come back as plain text that says what to do, without a documented catalogue (8 of 15). Version tags and GitHub releases, no changelog (5 of 15). 25 + 10 + 15 + 12 + 8 + 5 = 75.

Powens 48

No OpenAPI file or other machine-readable contract was found. The reference is hand-written GitBook tables (0 of 25). Both docs spaces publish llms.txt and a Markdown twin of every page (10). Each resource page opens with what the resource is, and endpoints say which token they need and how soft-deleted items behave. Several endpoints have no description beyond the title (12 of 20). Parameters and objects are in tables with types, required marks and value lists for states and scopes. Configuration and client config are free key-value objects (9 of 15). Guides carry curl requests and JSON responses. The reference pages read have few examples, and the errors page lists five common codes and warns that others may appear (9 of 15). The version is in the path (2.0). The changelog is a Notion page that is drawn by script and was not read (8 of 15).

BankMCP 50

MIT, source public (30). The README and site say what is stored (consents, account ids, watches, hashed tokens) and that balances and transactions aren't, and that data passes through Enable Banking (25 of 30). No deprecation policy for a 0.1 project (3 of 20). The README says it sends no telemetry (20). 30 + 25 + 3 + 20 = 78.

Powens 65

Closed service with public General Terms and Conditions of Sale under French law. The page has no version or date. The iOS SDK is LGPL-3.0 (15 of 30). The conditions of sale include a data protection annex, say collected data is destroyed at most 30 days after the contract ends, and the privacy policy gives retention periods by purpose. Neither page is dated, and the end-user terms say no data leaves the EU while the privacy policy lists business tools with transfers outside it (22 of 30). Obsolete and deprecated items are marked in the docs with no dates, and the conditions of sale say backward compatibility is assured but may be limited, with no notice period (5 of 20). The conditions of sale name Sewan and AWS, OVH and Gemalto in France and Unnax and CRIF in Spain and Italy, and commit to servers in the EU (17 of 20). Regulatory standing counts here as an addition to the checklist, as for the other bank data listings. Powens SAS is a payment institution registered with the ACPR under CIB 16948 (+5).

BankMCP 70

15 compact tools, plus an attestation-only tool set for a bank:attest grant (18 of 25). Transactions are paged through Enable Banking's continuation key with a page cap, and search_transactions and monthly_summary cut output (16 of 20). Errors explain the fix, such as sending the owner to the setup page (14 of 20). Reads are safe to repeat and there are no payment tools, but no readOnlyHint or other annotations (10 of 20). One npx line for local use, sensible defaults such as the configured country; hosting needs an Enable Banking key and a password (12 of 15). 18 + 16 + 14 + 10 + 12 = 70.

Powens 57

Lists take limit up to 1,000 and expand pulls linked resources into one response. No field selection was found (17 of 25). limit and offset on most lists, opaque cursor links in _links on transactions, and min_date, max_date, last_update, value and wording filters (18 of 20). One error format with code, description, an optional bank message and request_id, and advice to branch on the code. The documented code list is short (13 of 20). No idempotency key was found, including on POST /payments. Reads are safe to repeat (4 of 20). A first data call needs a console domain, a client application, a user token, a temporary code and a browser consent. limit is required on transactions. The only SDK found is an iOS beta from 2024 (5 of 15).
